Introduction This study examined trajectories of tobacco dependence (TD) in relation to changes in tobacco product use and explored the effects of product-specific adding, switching, or discontinued use on dependence over time. Aims and Methods Data were analyzed from the first three waves of the Population Assessment of Tobacco and Health (PATH) Study, a nationally representative, longitudinal study of adults and youth in the United States. Data included 9556 Wave 1 (2013/2014) adult current established tobacco users who completed all three interviews and had established use at ≥2 assessments. Groups included cigarettes-only users, e-cigarettes-only users, cigars-only users, hookah-only users, any smokeless-only users, cigarette + e-cigarette dual users, and multiple product users. A validated 16-item scale assessed TD across product users. Results Wave 1 e-cigarette-only users’ who maintained exclusive e-cigarette use increased levels of TD through Wave 3 as did those who added or switched to another product. Wave 1 multiple product users’ TD decreased across waves. TD for all other Wave 1 user groups remained about the same. For Wave 1 cigarette-only smokers, switching to another product or moving to a pattern of no established use was associated with lower levels of TD than smokers whose use stayed the same. Movement to no established use of any tobacco product was consistently associated with lower TD for all other product users. Conclusions Except for Wave 1 e-cigarette-only users, TD among US tobacco product users was stable over time, with daily users less likely to vary from baseline. Implications The level of TD among most US tobacco users was stable over the first three waves of the PATH Study and trends in levels of TD were predominantly unrelated to changes in patterns of continued product use. Stable levels of TD suggest a population at persistent risk of health impacts from tobacco. Wave 1 e-cigarette users, including those maintaining exclusive e-cigarette use, experienced increasing levels of TD over time, perhaps because of increases in quantity or frequency of their e-cigarette product use or increasing efficiency of nicotine delivery over time.

Background Prior work established a measure of tobacco dependence (TD) among adults that can be used to compare TD across different tobacco products. We extend this approach to develop a common, cross-product metric for TD among youth. Methods 1,148 youth ages 12 to 17 who used a tobacco product in the past 30-days who were identified from 13,651 youth respondents in Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study. Findings Analyses confirmed a single primary latent construct underlying responses to TD indicators for all mutually exclusive tobacco product user groups. Differential Item Functioning (DIF) analyses supported use of 8 of 10 TD indicators for comparisons across groups. With TD levels anchored at 0.0 (standard deviation (SD)=1.0) among cigarette only (n=265) use group, mean TD scores were more than a full SD lower for e-cigarette only (n=150) use group (mean=-1.09; SD=0.64). Other single product use group (cigar, hookah, pipe, or smokeless; n=262) on average had lower TD (mean=-0.60; SD= 0.84), and the group with use of multiple tobacco products (n=471) experienced similar levels of TD (mean=0.14; SD= 0.78) as the cigarette only use group. Concurrent validity was established with product use frequency among all user groups. A subset of 5 TD items comprised a common metric permitting comparisons between youth and adults. Conclusion The PATH Study Youth Wave 1 Interview provided psychometrically valid measures of TD that enables future regulatory investigations of TD across tobacco products and comparisons between youth and adult tobacco product use group. Implications A measure of tobacco dependence (TD) has been established previously among adults to compare TD across tobacco products. This study established the validity of a similar, cross-product measure of TD among youth. Findings suggest a single latent TD construct underlying this measure, concurrent validity of the scale with product use frequency across different types of tobacco users, and a subset of common items that can be used to compare TD between youth and adults who use tobacco.

Introduction This study examines predictors of trajectories of cigarette and e-cigarette use among a cohort of US adolescents transitioning into young adulthood. Comparing trajectories of each tobacco product is important to determine if different intervention targets are needed to prevent progression to daily use. Methods Latent trajectory class analyses identified cigarette and e-cigarette use (never, ever excluding past 12-month, past 12-month (excluding past 30-day (P30D)), P30D 1–5 days, P30D 6+ days) trajectory classes, separately, among US youth (12–17; N = 10,086) using the first 4 waves (2013–2017) of data from the nationally representative PATH Study. Weighted descriptive analyses described the class characteristics. Weighted multinomial logistic regression analyses examined demographic, psychosocial, and behavioral predictors of class membership. Results Younger adolescents 12–15 years had lower tobacco use compared to 16–17 year olds and less stable classes. In the 16–17 year group, there were five unique trajectories of cigarette smoking, including a Persistent High Frequency class. Four e-cigarette use trajectories were identified; but not a persistent use class. Shared predictors of class membership for cigarettes and e-cigarettes included mental health problems, other tobacco use, marijuana use, and poorer academic achievement. Male sex and household tobacco use were unique e-cigarette trajectory class predictors. Conclusions There was no evidence that initiation with e-cigarettes as the first product tried was associated with cigarette progression (nor cigarettes as first product and e-cigarette progression). Interventions should focus on well-established risk factors such as mental health and other substance use to prevent progression of use for both tobacco products. Implications Using nationally representative data and definitions of use that take into account frequency and recency of use, longitudinal 4-year trajectories of e-cigarette and cigarette use among US adolescents transitioning into young adulthood were identified. Results among 16–17-year olds revealed a class of persistent high frequency cigarette smoking that was not identified for e-cigarette use. Cigarette use progression was not associated with e-cigarettes as the first product tried. Risk factors for progression of use of both products included mental health and other substance use, which are important prevention targets for both tobacco products.

Introduction To date, no studies have evaluated the consistency of biomarker levels in people who smoke over a long-time period in real-world conditions with a large number of subjects and included use behavior and measures of nicotine metabolism. We evaluated the variability of biomarkers of nicotine exposure over approximately a 1-year period in people who exclusively smoke cigarettes, including intensity and recency of use and brand switching to assess impact on understanding associations with product characteristics. Aims and Methods Multivariate regression analysis of longitudinal repeated measures of urinary biomarkers of nicotine exposure from 916 adults in the Population Assessment of Tobacco and Health (PATH) Study with demographic characteristics and use behavior variables. Intraclass correlation coefficients (ICCs) were calculated to examine individual variation of nicotine biomarkers and the uncertainty of repeat measures at two time points (Waves 1 and 2). Results Age, race, and urinary creatinine were significant covariates of urinary cotinine. When including use behavior, recency, and intensity of use were highly significant and variance decreased to a higher extent between than within subjects. The ICC for urinary cotinine decreased from 0.7530 with no use behavior variables in the model to 0.5763 when included. Similar results were found for total nicotine equivalents. Conclusions Urinary nicotine biomarkers in the PATH Study showed good consistency between Waves 1 and 2. Use behavior measures such as time since last smoked a cigarette and number of cigarettes smoked in the past 30 days are important to include when assessing factors that may influence biomarker concentrations. Implications The results of this study show that the consistency of the nicotine biomarkers cotinine and total nicotine equivalents in spot urine samples from Waves 1 to 2 of the PATH Study is high enough that these data are useful to evaluate the association of cigarette characteristics with biomarkers of exposure under real-world use conditions.

IntroductionWhile risk factors for cigarette smoking among youth and young adults are well-documented, less is known about the correlates of initiation of other tobacco products. This study aims to provide estimates and correlates of initiation among U.S. youth and young adults.MethodsData on youth aged 12-17 (n=10,072) and young adults aged 18-24 (N=5,727) who provided information on cigarettes, electronic nicotine delivery systems (ENDS), cigars, pipe, hookah and smokeless tobacco use in Wave 1 (W1: 2013-2014)-Wave 4 (W4: 2016-2018) of the nationally-representative PATH Study were used to calculate ever use initiation and correlates of initiation by W4.ResultsNearly 6 million youth and 2.5 million young adults used tobacco for the first time between W1-W4. Approximately one quarter of youth and young adult ENDS never users initiated ENDS between W1-W4 of the PATH Study. Among youth, use of other tobacco products, ever substance use, and high externalizing problems were associated with initiation of most products. Among young adults, use of other tobacco products and ever substance use were associated with initiation of most products. In both youth and young adults, Hispanics were more likely to initiate hookah use than their non-Hispanic White counterparts. While male sex was a risk factor for most tobacco product initiation across both age groups, it was not associated with hookah initiation.ConclusionsCigarette and non-cigarette products shared many correlates of initiation, although there are noteworthy demographic differences. Findings can help tailor product specific interventions to reach populations at risk during preliminary stages of use.

ImportanceAdults with psychotic disorders have high premature mortality, partly due to the high prevalence of smoking in this population. Yet recent data are lacking on tobacco product use among US adults with a history of psychosis.ObjectiveTo examine the sociodemographic characteristics and behavioral health status; types of tobacco products used; prevalence of use by age, sex, and race and ethnicity; and nicotine dependence severity and smoking cessation methods among community-dwelling adults with vs without psychosis.Design, Setting, and ParticipantsThis cross-sectional study analyzed nationally representative, self-reported, cross-sectional data of adults (aged ≥18 years) who participated in the Wave 5 survey (conducted from December 2018 to November 2019) of the Population Assessment of Tobacco and Health (PATH) Study. Data analyses were conducted between September 2021 and October 2022.ExposurePATH Study respondents were classified as having lifetime psychosis if they answered yes to whether they had ever received from a clinician (eg, physician, therapist, or other mental health professional) a diagnosis of schizophrenia, schizoaffective disorder, psychosis, or psychotic illness or episode.Main Outcomes and MeasuresUse of any and major types of tobacco products, severity of nicotine dependence, and cessation methods.ResultsAmong the 29 045 community-dwelling adults who participated in the PATH Study (weighted median [IQR] age, 30.0 [22.0-50.0] years; weighted percentage estimates: 14 976 females (51.5%); 16.0% Hispanic, 11.1% non-Hispanic Black, 65.0% non-Hispanic White, and 8.0% non-Hispanic other race and ethnicity [American Indian or Alaska Native, Asian, Native Hawaiian or other Pacific Islander, and more than 1 race]), 2.9% (95% CI, 2.62%-3.10%) reported receiving a lifetime psychosis diagnosis. Compared with those without psychosis, people with psychosis had a higher adjusted prevalence of past-month any tobacco use (41.3% vs 27.7%; adjusted risk ratio [RR], 1.49 [95% CI, 1.36-1.63]) as well as cigarette smoking, e-cigarette use, and other tobacco product use overall and in most examined subgroups; they also had a higher past-month prevalence of dual cigarette and e-cigarette use (13.5% vs 10.1%; P = .02), polycombustible tobacco use (12.1% vs 8.6%; P = .007), and polycombustible and noncombustible tobacco use (22.1% vs 12.4%; P P P = .002), female (56.9 vs 49.8; P = .001), Hispanic (53.7 vs 40.0; P = .01), and Black (53.4 vs 46.0; P = .005) groups. They were also more likely to make a quit attempt (60.0% vs 54.1%; adjusted RR, 1.11 [95% CI, 1.01-1.21]) and use counseling, a quitline, or a support group for tobacco cessation (5.6% vs 2.5%; adjusted RR, 2.25 [95% CI, 1.21-3.30]).Conclusions and RelevanceIn this study, the high prevalence of tobacco use, polytobacco use, and making a quit attempt as well as the severity of nicotine dependence among community-dwelling adults with a history of psychosis highlighted the urgency for tailored tobacco cessation interventions for this population. Such strategies must be evidence-based and age, sex, and race and ethnicity appropriate.

Background: The purpose of this study was to examine the association between established cigar use and prevalence and incidence of cardiovascular diseases (CVD; congestive heart failure, stroke, or heart attack/needed bypass surgery) among U.S. adults, 40 years or older. The study also explored if years of use, is associated with CVD prevalence. Methods: Using Waves 1-5 (2013-2019) of the Population Assessment of Tobacco and Health (PATH) Study, a nationally representative, longitudinal cohort study of U.S. adults and youth, pooled prevalence, restricted to adults 40 and older who provided data at every wave (N=10,128 unique respondents and Nobs=46,294;), was estimated to understand the association between established cigar use and self-reported CVD outcomes. Weighted generalized estimating equations were used to examine CVD outcomes among exclusive current/former established cigar smokers (ever cigar smokers who have smoked fairly regularly), exclusive current/former established cigarette smokers (lifetime smokers of 100 or more cigarettes), dual current/former established cigarette and cigar smokers compared to never smokers of cigars or cigarettes, adjusting for covariates. Results: The incidence of CVD among exclusive current/former established cigar smokers over a six-year period was low (overall average rate of 3.0%). The pooled-prevalence of CVD outcome was very similar among exclusive current/former established cigar smokers (10.7%; 95% CI: 7.0-16.1) and exclusive current/former established cigarette smokers (10.7%; 95% CI: 9.4-12.2) and slightly higher among dual users of cigars and cigarettes (14.3%; 95% CI: 11.8-17.1). Compared to never users, exclusive current/former established cigar smokers (OR = 1.67, 95% CI: 1.11-2.51) and exclusive current/former established cigarette smokers (OR = 2.12, 95% CI: 1.45-3.09) were more likely to have any CVD outcome in unadjusted analyses. When adjusted for covariates, only exclusive current/former established cigarette use was associated with CVD outcomes (AOR = 1.63, CI: 1.05-2.53). We did not find a consistent dose response relationship between duration of exclusive current/former established cigar use and CVD prevalence. Conclusions: Understanding how cigar use impacts CVD is important in reducing tobacco-related mortality and morbidity. In this study, exclusive established use of cigars or duration of exclusive cigar use was not associated with CVD prevalence compared to never cigar or cigarette smokers.

Background: Prior studies have not clearly established risk of cardiovascular disease (CVD) among smokers who switch to exclusive use of electronic nicotine delivery systems (ENDS). We compared cardiovascular disease incidence in combustible-tobacco users, those who transitioned to ENDS use, and those who quit tobacco with never tobacco users. Methods: This prospective cohort study analyzes five waves of Population Assessment of Tobacco and Health (PATH) Study data, Wave 1 (2013–2014) through Wave 5 (2018–2019). Cardiovascular disease (CVD) incidence was captured over three intervals (Waves 1 to 3, Waves 2 to 4, and Waves 3 to 5). Participants were adults (40+ years old) without a history of CVD for the first two waves of any interval. Change in tobacco use status, from exclusive past 30 day use of any combustible-tobacco product to either exclusive past 30 day ENDS use, dual past 30 day use of ENDS and combustible-tobacco, or no past 30 day use of any tobacco, between the first two waves of an interval was used to predict onset of CVD between the second and third waves in the interval. CVD incidence was defined as a new self-report of being told by a health professional that they had congestive heart failure, stroke, or a myocardial infarction. Generalized estimating equation (GEE) analyses combined 10,548 observations across intervals from 7820 eligible respondents. Results: Overall, there were 191 observations of CVD among 10,548 total observations (1.7%, standard error (SE) = 0.2), with 40 among 3014 never users of tobacco (1.5%, SE = 0.3). In multivariable models, CVD incidence was not significantly different for any tobacco user groups compared to never users. There were 126 observations of CVD among 6263 continuing exclusive combustible-tobacco users (adjusted odds ratio [AOR] = 1.44; 95% confidence interval (CI) 0.87–2.39), 15 observations of CVD among 565 who transitioned to dual use (AOR = 1.85; 0.78–4.37), and 10 observations of CVD among 654 who quit using tobacco (AOR = 1.18; 0.33–4.26). There were no observations of CVD among 53 who transitioned to exclusive ENDS use. Conclusions: This study found no difference in CVD incidence by tobacco status over three 3 year intervals, even for tobacco quitters. It is possible that additional waves of PATH Study data, combined with information from other large longitudinal cohorts with careful tracking of ENDS use patterns may help to further clarify this relationship.

Introduction This study examined the predictive relationships between biomarkers of nicotine exposure and 16-item self-reported level of tobacco dependence (TD) and subsequent tobacco use outcomes. Aims and Methods The Population Assessment of Tobacco and Health (PATH) Study surveyed adult current established tobacco users who provided urine biospecimens at Wave 1 (September 2013–December 2014) and completed the Wave 2 (October 2014–October 2015) interview (n = 6872). Mutually exclusive user groups at Wave 1 included: Cigarette Only, E-cigarette Only, Cigar Only, Hookah Only, Smokeless Tobacco Only, Cigarette Plus E-cigarette, multiple tobacco product users who smoked cigarettes, and multiple tobacco product users who did not smoke cigarettes. Total Nicotine Equivalents (TNE-2) and TD were measured at Wave 1. Approximate one-year outcomes included frequency/quantity used, quitting, and adding/switching to different tobacco products. Results For Cigarette Only smokers and multiple tobacco product users who smoked cigarettes, higher TD and TNE-2 were associated with: a tendency to smoke more, smoking more frequently over time, decreased likelihood of switching away from cigarettes, and decreased probability of quitting after one year. For other product user groups, Wave 1 TD and/or TNE-2 were less consistently related to changes in quantity and frequency of product use, or for adding or switching products, but higher TNE-2 was more consistently predictive of decreased probability of quitting. Conclusions Self-reported TD and nicotine exposure assess common and independent aspects of dependence in relation to tobacco use behaviors for cigarette smokers. For other product user groups, nicotine exposure is a more consistent predictor of quitting than self-reported TD. Implications This study suggests that smoking cigarettes leads to the most coherent pattern of associations consistent with a syndrome of TD. Because cigarettes continue to be prevalent and harmful, efforts to decrease their use may be accelerated via conventional means (eg, smoking cessation interventions and treatments), but also perhaps by decreasing their dependence potential. The implications for noncombustible tobacco products are less clear as the stability of tobacco use patterns that include products such as e-cigarettes continue to evolve. TD, nicotine exposure measures, and consumption could be used in studies that attempt to understand and predict product-specific tobacco use behavioral outcomes.

ImportanceInformation about national substance use trends among youths and adults after mid-March 2020 is limited due to constraints on surveillance during the COVID-19 pandemic.ObjectiveTo evaluate whether substance use prevalence in the early part of the pandemic (2020) differed from the prepandemic periods of 2018 to 2019 and 2016 to 2018.Design, Setting, and ParticipantsThis cross-sectional study was a repeated analysis of 2016 to 2020 data from a nationally representative sample of youths and adults in the Population Assessment of Tobacco and Health (PATH) Study. Participants were representative of the US civilian noninstitutionalized population. Household residents age 13 years or older were interviewed in person from 2016 to 2019 and via telephone in 2020.ExposuresAge, calendar year.Main Outcomes and MeasuresPast 30-day self-reported use of any tobacco, any alcohol, binge drinking, cannabis, and any other illegal or misused prescription drugs.ResultsThe overall nationally representative 2020 sample included 7129 youths (ages 13-17 years), 3628 young adults (ages 18-20 years), and 8874 adults (ages ≥21 years). Comparing 2018 to 2019 with 2020 among youths, prevalence of all substances used declined (eg, cannabis use declined in those aged 16-17 years from 14.9% to 7.6%; absolute difference, −7.3 percentage points [95% CI −8.8 to −5.8 percentage points]). Among young adults, prevalence of all substances other than any alcohol decreased significantly (eg, tobacco use declined from 37.8% to 22.8%; absolute difference, −15.1 percentage points [95% CI −16.8 to −13.3 percentage points]). In adults ages 21 to 24 years, any tobacco use declined from 39.0% to 30.9% (absolute difference, −8.2 percentage points [95% CI, −10.6 to −5.7 percentage points]), and alcohol use increased from 60.2% to 65.2% (absolute difference, 5.0 percentage points [95% CI, 2.3 to 7.7 percentage points]). Among adults aged 25 years or older, any tobacco use declined from 39.0% to 30.9% (absolute difference, −8.2 percentage points [95% CI, −10.6 to −5.7 percentage points]), cannabis use increased from 11.3% to 12.4% (absolute difference, 1.2 percentage points [95% CI, 0.3 to 2.0 percentage points]), and other substance use declined from 5.8% to 3.7% (absolute difference, −2.1 percentage points [95% CI, −2.9 to −1.4 percentage points]).Conclusions and RelevanceIn this cross-sectional study, substance use decreased between 2019 and 2020 among those aged 13 to 20 years; consistent declines were not seen in older persons other than tobacco use reductions, and cannabis use increased among adults ages 25 years and older. While social changes during the COVID-19 pandemic could have affected substance use, findings should be interpreted with caution due to differences in data collection methods in 2016 to 2019 and 2020.

ImportanceEvolving tobacco use patterns, including increasing electronic nicotine delivery systems (ENDS) use, warrant re-examination of the associations between tobacco use and oral health.ObjectiveTo examine associations between tobacco product use and incidence of adverse oral health outcomes.Design, Setting, and ParticipantsThis cohort study used nationally representative data from wave (W) 1 to W5 (2013-2019) of the Population Assessment of Tobacco and Health Study. Recruitment used a stratified address-based, area-probability household sample of the noninstitutionalized US civilian population. The W1 cohort included respondents aged 18 years and older without lifetime history of oral health outcomes at W1 or W3, depending on when the outcome was first assessed. Data analysis was performed from October 2021 to September 2022.ExposuresCurrent (every day or someday use) established (lifetime use of at least 100 cigarettes or “fairly regular” use of other products) use of cigarettes, ENDS, cigars, pipes, hookah, snus, and smokeless tobacco, excluding snus at W1 to W4.Main Outcomes and MeasuresThe primary outcomes were past 12-month self-reported diagnosis of gum disease and precancerous oral lesions (W2-W5) and bone loss around teeth, bleeding after brushing or flossing, loose teeth, and 1 or more teeth removed (W4-W5).ResultsSample sizes varied across the 6 oral health outcomes (13 149 respondents for the gum disease sample, 14 993 respondents for the precancerous oral lesions sample, 16 312 respondents for the bone loss around teeth sample, 10 286 respondents for the bleeding after brushing or flossing sample, 15 686 respondents for the loose teeth sample, and 12 061 respondents for the 1 or more teeth removed sample). Slightly more than half of adults (52%-54% across the 6 samples) were women, and the majority were of non-Hispanic White race and ethnicity. Cox proportional hazards models were developed with covariates that included time-dependent tobacco use variables mutually adjusted for each other. Cigarette smoking was positively associated with incidence of gum disease diagnosis (adjusted hazard ratio [AHR], 1.33; 95% CI, 1.11-1.60), loose teeth (AHR, 1.35; 95% CI, 1.05-1.75), and 1 or more teeth removed (AHR, 1.43; 95% CI, 1.18-1.74). Cigar smoking was positively associated with incidence of precancerous oral lesions (AHR, 2.18; 95% CI, 1.38-3.43). In addition, hookah smoking was positively associated with incidence of gum disease diagnosis (AHR, 1.78; 95% CI, 1.20-2.63), and ENDS use was positively associated with incidence of bleeding after brushing or flossing (AHR, 1.27; 95% CI, 1.04-1.54). No associations were observed between snus and smokeless tobacco excluding snus and incidence of oral health outcomes.Conclusions and RelevanceThe observed associations of combustible tobacco use with incidence of several adverse oral health outcomes and ENDS use with incidence of bleeding after brushing or flossing highlight the importance of longitudinal studies and emphasize the continued importance of tobacco cessation counseling and resources in clinical practice.

BackgroundEvidence is accumulating that youth who try Electronic Nicotine Delivery Systems (ENDS, e-cigarettes) may go on to try cigarettes. This analysis examines the bidirectional patterns of ENDS and cigarette use among US youth over one year and uses propensity score matching (PSM) to examine frequency of ENDS use on changes in cigarette smoking.MethodsOur analysis included 11 996 participants who had two waves of available data (Wave 1 [W1] 2013–2014; Wave 2 [W2] 2014–2015) drawn from the longitudinal Population Assessment of Tobacco and Health Study. Cross-sectional weighted prevalence estimates are reported for cigarettes and ENDS. We used PSM to estimate the likelihood of ENDS use at W1 and to draw matched analytic samples, then used regression (logistic or linear) models to examine the effect of W1 ENDS use on W2 cigarette smoking. All statistical tests were two-sided.ResultsIn weighted analyses, 69.3% of W1 past-30-day cigarette smokers exhibited past-30-day smoking at W2; 42.2% of W1 past-30-day ENDS users were using ENDS at W2. W1 ever use of either product was similarly associated with W2 new use of the other product. Unweighted PSM models indicated W1 cigarette-naïve ENDS use was associated with W2 ever-cigarette smoking (n = 676; adjusted odds ratio = 3.21, 95% confidence interval [CI] = 1.95 to 5.45, P ConclusionsEver-ENDS use predicts future cigarette smoking, and frequency of ENDS use has a differential impact on subsequent cigarette smoking uptake or reduction. These results suggest that both cigarettes and ENDS should be targeted in early tobacco prevention efforts with youth.

Objective This study investigated the role of self-perceived oral health and normative need on dental services utilization by US adults aged ≥30 years from the 2011-2014 National Health and Nutrition Examination Survey (NHANES). Methods Data on 5,806 dentate adult NHANES participants were analyzed. Key independent variables were self-perceived oral health and normative need assessed by a dentist. The dependent variable was dental visit within the past 12 months. Select sociodemographic variables were adjusted for in logistic regression models using SAS survey procedures. Results Overall, 33.8 percent of adults did not have a dental visit in the past 12 months. About 26.9 percent reported they were unsatisfied with their oral health and 53.4 percent needed to seek care. Individuals unsatisfied with their oral health were less likely to have a dental visit in the past 12 months compared to those who were satisfied with their oral health (57 versus 25 percent). Overall, participants who were unsatisfied with their oral health received a recommendation to seek care. These participants had more normative needs and were less likely to have a dental visit in the past 12 months; however, this relationship varied by race/ethnicity. For Asian-Americans, there was no association between those unsatisfied with their oral health and dental visits. Also, there was no association across all race/ethnicities between number of teeth present and dental visits. Conclusion Both self-perceived oral health and normative need are associated with dental utilization. Results will contribute to health policy discussions and program development that aim to improve oral health status in the United States.

Flavored non-cigarette tobacco product use is widespread in the U.S. The availability of flavor options could be playing a role in recent increases in use, especially for non-cigarette tobacco products, among youth and young adults. Little is known about specific flavor preferences of youth and adult flavored tobacco product users, as well as how preferences may change over time.This study analyzes PATH Study data from completed Wave 2 (2014-2015) and Wave 3 (2015-2016) youth (12-17 years), and adult (18 + years) interviews to estimate the prevalence of flavored non-cigarette tobacco product use. We assess flavor switching by examining changes between flavors and characteristics of those who changed flavors between waves.Across age groups, and at both waves, fruit-flavored products were the most frequently used flavor by past 30-day electronic nicotine delivery systems (ENDS), cigar, cigarillo, and hookah users. In the past 30 days, a higher proportion of youth and young adults used candy/sweets-flavored ENDS than adults. Among adult ENDS users, the odds of changing flavors were highest among younger users and decreased with increasing age.Flavored tobacco product use is prevalent across non-cigarette tobacco products. Stability in the number of flavors used, as well as specific flavors, is higher among adult tobacco users, while the use of multiple flavors, and change in specific flavor, is more prevalent among youth tobacco users. Additional longitudinal research can further examine the role flavors play in appeal, product trial, and switching.

Potential mechanisms by which e-cigarette use may relate to combustible cigarette smoking cessation are not well-understood. We used U.S. nationally representative data to prospectively evaluate the relationship between e-cigarette flavor use and frequency of e-cigarette use among adult cigarette/e-cigarette dual users who attempted to quit smoking cigarettes. Analyses used Population Assessment of Tobacco and Health (PATH) Study data from adult dual users (2015/16) who attempted to quit smoking between 2015/16 and 2016/17 (Wave 3-Wave 4, n = 685, including those who did/did not quit by 2016/17). E-cigarette flavor use (usual/last flavor, past 30-day flavor; assessed in 2015/16) was categorized into Only tobacco; Only menthol/mint; Only non-tobacco, non-menthol/mint; and Any combination of tobacco, menthol/mint, other flavor(s). The key outcome, evaluated at follow-up in 2016/17, was frequent e-cigarette use, which was defined as use on 20+ of past 30 days. Logistic regression was used to evaluate associations between e-cigarette flavor use in 2015/16 and frequent e-cigarette use at follow-up in 2016/17. Dual users who attempted to quit smoking had greater odds of frequent e-cigarette use at follow-up when they used only non-tobacco, non-menthol/mint flavor than when they used only tobacco flavor as their regular/last e-cigarette flavor (OR = 1.9, 95% CI: 1.1–3.4); findings were no longer significant when adjusted for factors including e-cigarette device type (AOR = 1.4, 95% CI: 0.7–2.8). Past 30-day e-cigarette flavor use results were generally similar, although frequent e-cigarette use at follow-up was highest among those who used any combination of tobacco, menthol/mint, or other flavors. Findings indicate that e-cigarette flavor use among dual users who attempt to quit smoking may be related to e-cigarette use frequency overall, which may indicate a mechanism underlying findings for e-cigarette use and smoking cessation. Further longitudinal research may help to disentangle how e-cigarette characteristics uniquely impact e-cigarette use frequency and smoking cessation/sustained use.

We examined whether tobacco susceptibility at Wave (W) 1 (2013–2014) predicts the onset of tobacco and other substances at W2 (2014–2015) among 5325 U.S. youth (12–17 years) never substance users at W1 in the Population Assessment of Tobacco and Health (PATH) Study. Tobacco susceptibility was based on curiosity, use intentions, and response to a best friend's offer to use. Onset of use included past 12-month use of a specific substance or group of substances at W2 among those who had never used any substance at W1. Approximately, 31.3% of W1 youth were susceptible to tobacco use. W2 onset was 8.2% (SE = 0.4) for alcohol exclusively, 5.0% (SE = 0.4) for polysubstance including tobacco, 4.4% (SE = 0.3) for tobacco exclusively, 3.1% (SE = 0.3) for other drugs (misused prescription stimulants and painkillers, cocaine, other stimulants, heroin, inhalants, solvents and hallucinogens) exclusively, 1.4% (SE = 0.2) for polysubstance excluding tobacco, and 0.9% (SE = 0.1) for marijuana exclusively. Tobacco-susceptible compared with non-tobacco susceptible youth had higher odds of onset of exclusive tobacco use (AOR: 2.4; 95% CI: 1.7, 3.3), exclusive alcohol use (AOR: 1.5; 95% CI: 1.2, 1.8), and polysubstance use (AOR: 3.9; 95% CI: 2.8, 5.6 including tobacco and AOR: 1.8; 95% CI: 1.1, 3.0 excluding tobacco) compared with W2 never substance use. In this national study, tobacco susceptibility identified U.S. youth at risk for onset of tobacco and other substances, perhaps reflecting common etiology and clustering of substance use in youth. Identifying and preventing tobacco-susceptible youth from progressing to using addictive substances must remain a public health priority.

Purpose This study examined U.S. middle and high school student observations of electronic nicotine product (ENP) use in and around the school building and students’ normative perceptions of use among peers. Methods Adolescents and young adult participants enrolled in middle (n = 672) or high school (n = 962) were recruited from an online nationally representative panel and surveyed from November 2 to 15, 2018. They answered questions on observed ENP use in and around the school building as well as perceptions of use among peers. Results Nearly one in five U.S. middle and high school students believed that at least half of their peers used ENPs. Confirming anecdotal reports, nearly six in 10 reported ever seeing someone use ENPs in or around their school, most often outside the school building and in bathrooms or locker rooms. Conclusions The findings of this study underscore the importance of targeted prevention strategies and education efforts to prevent and combat adolescent ENP use in and around schools.

BackgroundMore smokers report using e-cigarettes to help them quit than FDA-approved pharmacotherapy.ObjectiveTo assess the association of e-cigarettes with future abstinence from cigarette and tobacco use.DesignCohort study of US sample, with annual follow-up.ParticipantsUS adult (ages 18+) daily cigarette smokers identified at Wave 1 (W1; 2013-14) of the PATH Study, who reported a quit attempt before W2 and completed W3 (n = 2443).ExposuresUse of e-cigarettes, pharmacotherapy (including nicotine replacement therapy), or no product for last quit attempt (LQA), and current daily e-cigarette use at W2.AnalysisPropensity score matching (PSM) of groups using different methods to quit.Outcome measures12+ months abstinence at W3 from cigarettes and from all tobacco (including e-cigarettes). 30+ days abstinence at W3 was a secondary outcome.ResultsAmong daily smokers with an LQA, 23.5% used e-cigarettes, 19.3% used pharmacotherapy only (including NRT) and 57.2% used no product. Cigarette abstinence for 12+ months at W3 was ~10% in each group. Half of the cigarette abstainers in the e-cigarette group were using e-cigarettes at W3. Different methods to help quitting had statistically comparable 12+ month cigarette abstinence at W3 (e-cigarettes vs no product: Risk Difference (RD) = 0.01, 95% CI: -0.04 to 0.06; e-cigarettes vs pharmacotherapy: RD = 0.02, 95% CI:-0.04 to 0.09). Likewise, daily e-cigarette users at W2 did not show a cessation benefit over comparable no-e-cigarette users and this finding was robust to sensitivity analyses. Abstinence for 30+ days at W3 was also similar across products.LimitationsThe frequency of e-cigarette use during the LQA was not assessed, nor was it possible to assess continuous abstinence from the LQA.ConclusionAmong US daily smokers who quit cigarettes in 2014-15, use of e-cigarettes in that attempt compared to approved cessation aids or no products showed similar abstinence rates 1-2 years later.

Background and aims Building on published work1 establishing concurrent validity of a self-report tobacco dependence (TD) index among users of different tobacco products in Wave 1 (W1) of the Population Assessment of Tobacco and Health (PATH) Study, the current study examines prospective relationships with tobacco use behaviors to establish predictive validity of the TD index. Hypotheses suggested high levels of W1 TD would be associated with persistent tobacco use at Wave 2 (W2). Participants A U.S. nationally representative sample of 32,320 adult W1 and W2 interviews focused on 11,615 W1 adults who were current established tobacco users and completed the W2 interview. Findings Higher TD scores and greater changes in TD scores were associated with greater quantity and frequency of tobacco use at the W2 interview for Cigarette Only (n = 7068), Smokeless (smokeless or snus pouches) Only (n = 772), Cigarette plus E-Cigarette (n = 592), and Multiple Products (n = 1866) users, although not significantly so for E-Cigarette Only (n = 367), Cigar Only (traditional, cigarillo, or filtered) (n = 584), or Hookah Only (n = 366) users. Higher TD was associated with decreased odds of successful quitting for Cigarette and Multiple Product users. Higher TD was associated with increased odds of a quit attempt for those in the Hookah and Multiple Products user groups and was not associated with quit attempts or deceased odds of quit success among exclusive E-Cigarette, Cigar, Smokeless and Cigarette plus E-Cigarette users. Conclusion Support for the predictive validity of the PATH Study measures of adult TD will enable regulatory investigations of TD across several tobacco products.

Objectives Suicide is a leading cause of death worldwide, and disproportionately affects Indigenous populations. Seasonal suicide patterns are variable in the literature, and could offer novel approaches to the timing and focus of prevention efforts if better understood. With a suicide surveillance system in place since 1989, this study offers an unprecedented opportunity to explore seasonal variations in both fatal and non-fatal suicide behavior in an Indigenous Arctic region. Study design Cross-sectional. Methods In this descriptive study, we analyzed data collected from 1990 to 2009 in the rural northwest region of Alaska, both graphically and using the chi-squared test for multinomials. Results We found a significant monthly variation for suicide attempts, with a peak in suicide behavior observed between April and August ( P = 0.0002). Monthly variation was more pronounced among individuals ≤29 years of age, and was present in both males and females, although the seasonal pattern differed by sex. Conclusions Our findings of a significant seasonal pattern in suicide behavior, with monthly variation (summer peak) in non-fatal suicide behavior among younger age groups, and among both males and females can assist planners in targeting subpopulations for prevention at different times of the year.

Objectives To prospectively evaluate the association between gestational weight gain (GWG), prepregnancy body mass index (BMI), and hypertensive disorders of pregnancy using the revised Institute of Medicine (IOM) Guidelines. Methods We examined these associations among 1359 participants in Proyecto Buena Salud, a prospective cohort study conducted from 2006 to 2011 among women from the Caribbean Islands. Information on prepregnancy BMI, GWG, and incident diagnoses of hypertension in pregnancy were based on medical record abstraction. Results Four percent (n = 54) of women were diagnosed with hypertension in pregnancy, including 2.6 % (n = 36) with preeclampsia. As compared to women who gained within IOM GWG guidelines (22.8 %), those who gained above guidelines (52.5 %) had an odds ratio of 3.82 for hypertensive disorders (95 % CI 1.46-10.00; ptrend = 0.003) and an odds ratio of 2.94 for preeclampsia (95 % CI 1.00-8.71, ptrend = 0.03) after adjusting for important risk factors. Each one standard deviation (0.45 lbs/week) increase in rate of GWG was associated with a 1.74 odds of total hypertensive disorders (95 % CI 1.34-2.27) and 1.86 odds of preeclampsia (95 % CI 1.37-2.52). Conclusions for Practice Findings from this prospective study suggest that excessive GWG is associated with hypertension in pregnancy and could be a potentially modifiable risk factor in this high-risk ethnic group.

Importance The prevalence of electronic nicotine delivery systems (ENDS) use, including e-cigarettes, among US young adults (YAs) has raised questions about how these products may affect future tobacco and nicotine use among YAs. Given this prevalence and that young adulthood is a critical period for the establishment of tobacco and nicotine use, it is important to consider the association between ENDS use and cigarette smoking specifically in this age group. Objective To examine whether ENDS use frequency or intensity is associated with changes in cigarette smoking among US YA ever smokers during 1 year. Design, Setting, and Participants This cohort study used 3 waves of data (2013-2014, 2014-2015, and 2015-2016) from the Population Assessment of Tobacco and Health (PATH) Study, an ongoing longitudinal cohort study of adults and youth. Unweighted 1:6 propensity score matching was used to match participants on wave 1 risk factors for ENDS use at wave 2. The changes in smoking between wave 2 and wave 3 were assessed using the matched sample. In total, 1096 ENDS-naive, ever cigarette–smoking YAs (18-24 years of age) at wave 1 who participated in wave 2 and wave 3 and who had complete data in the PATH Study were included in the analyses, which were conducted from August 2018 to October 2019. Exposures Never ENDS use (n = 987), any previous 30-day ENDS use (n = 109), 1 to 5 days of ENDS use in the previous 30 days (n = 75), and 6 or more days ENDS use in the previous 30 days at wave 2 (n = 34). Main Outcomes and Measures The analytic sample was selected using multiple variables based on peer-reviewed literature supporting associations with ENDS use. The main outcomes—changes in cigarette smoking behavior between wave 2 and wave 3—were defined using 2 measures: (1) change in smoking frequency, defined as the number of smoking days in the previous 30 days at wave 3 vs wave 2, and (2) change in smoking intensity, defined as the number smoking days in the previous 30 days multiplied by the mean number of cigarettes consumed on smoking days at wave 3 vs wave 2. Results The present cohort analyses included 1096 YA ever smokers who were ENDS naive at wave 1. The majority of the sample were women (609 [55.6%]) and White individuals (698 [63.7%]), and the mean (SD) age was 21.4 (1.9) years. In wave 1, 161 YAs (14.7%) were daily smokers in the previous 30 days. After propensity score matching, no statistically significant associations were observed between any definition of wave 2 ENDS use and changes in either the frequency or intensity of smoking at wave 3. Conclusions and Relevance In this cohort study of US YA ever smokers, ENDS use was not associated with either decreased or increased cigarette smoking during a 1-year period. However, it is possible that the rapidly evolving marketplace of vaping products may lead to different trajectories of YA cigarette and ENDS use in the future.

Importance Relapse to smoking among former smokers is a serious clinical concern, and use of electronic nicotine delivery systems (ENDS) has been proposed as a new risk factor for relapse. Understanding the specificity of this risk can help guide clinical practice and lead to improved health outcomes. Objective To assess the associations of ENDS use with cigarette smoking relapse among adult former cigarette smokers. Design, Setting, and Participants This cohort study examined data from the Population Assessment of Tobacco and Health Study, waves 1 to 4 (2013-2018). Cox proportional hazards models were developed. This is an ongoing, nationally representative, longitudinal cohort study in the US. Participants included adult (≥18 years) former cigarette smokers who reported no tobacco product use at wave 1 (unweighted n = 2273), separated into recent former cigarette smokers (last smoked ≤12 months previously) and long-term former smokers (last smoked >12 months previously). Data analysis was conducted from July to August 2019. Exposures Self-reported use of cigarettes, ENDS, and other tobacco products (ie, cigars, pipe tobacco, hookah, snus tobacco, other smokeless tobacco, and dissolvable tobacco) was assessed. Main Outcomes and Measures Self-reported current (every day or some days) use of cigarettes at follow-up interviews. Results Of 2273 adult former cigarette smokers, 51.8% (95% CI, 49.7%-53.8%) were women, 65.0% (95% CI, 62.6%-67.4%) were older than 50 years, and 79.5% (95% CI, 77.8%-81.2%) were non-Hispanic white participants. Use of ENDS was associated with significant risk of cigarette smoking relapse among recent former smokers (adjusted hazard ratio [AHR], 1.63; 95% CI, 1.04-2.53; unweighted n = 304) and among long-term former smokers (AHR, 3.79; 95% CI, 1.75-8.20; unweighted n = 1554). Use of other tobacco products was also associated with significant risk for cigarette smoking relapse among recent former smokers (AHR, 1.97; 95% CI, 1.27-3.05) and among long-term former smokers (AHR, 3.82; 95% CI, 1.91-7.66). Conclusions and Relevance In this study, use of ENDS and other tobacco products was associated with increased risk of cigarette smoking relapse among former cigarette smokers who did not use any tobacco product at wave 1 of the PATH Study. For clinicians treating former smokers who have successfully quit all nicotine products, the implications are that use of ENDS products should be discouraged, just as use of all other tobacco products is discouraged.

Objective To examine whether mental health problems predict incident use of 12 different tobacco products in a nationally representative sample of youth and young adults. Method This study analyzed Wave (W) 1 and W2 data from 10,533 12- to 24-year-old W1 never tobacco users in the Population Assessment of Tobacco and Health (PATH) Study. Self-reported lifetime internalizing and externalizing symptoms were assessed at W1. Past 12-month use of cigarettes, electronic nicotine delivery systems (ENDS), traditional cigars, cigarillos, filtered cigars, pipe, hookah, snus pouches, other smokeless tobacco, bidis and kreteks (youth only), and dissolvable tobacco was assessed at W2. Results In multivariable regression analyses, high-severity W1 internalizing (adjusted odds ratio [AOR] = 1.5, 95% CI = 1.3−1.8) and externalizing (AOR = 1.3, 95% CI = 1.1−1.5) problems predicted W2 onset of any tobacco use compared to no/low/moderate severity. High-severity W1 internalizing problems predicted W2 use onset across most tobacco products. High-severity W1 externalizing problems predicted onset of any tobacco (AOR = 1.6, 95% CI = 1.3−1.8), cigarettes (AOR = 1.4, 95% CI = 1.0−2.0), ENDS (AOR = 1.8, 95% CI = 1.5−2.1), and cigarillos (AOR = 1.5, 95% CI = 1.0−2.1) among youth only. Conclusion Internalizing and externalizing problems predicted onset of any tobacco use. However, findings differed for internalizing and externalizing problems across tobacco products, and by age, gender, and race/ethnicity. In addition to screening for tobacco product use, health care providers should screen for a range of mental health problems as a predictor of tobacco use. Interventions addressing mental health problems may prevent youth from initiating tobacco use.

Background and aims Youth aged 15-17 years are at high risk of tobacco, alcohol and drug use. Given the changing landscape with respect to availability, use of emerging products and regulatory environments, we examined patterns and correlates of polysubstance use among US youth aged 15-17 years. Design Cross-sectional self-reported data. Setting United States. Participants A total of 6127 US youth aged 15-17 years from wave 1 (2013-14) of the nationally representative Population Assessment of Tobacco and Health (PATH) Study. Measurements Latent class analysis was used to identify subgroups of polysubstance use, including 12 tobacco products, alcohol, marijuana, prescription drugs and other drugs. Socio-demographic characteristics, residence in urban area, sensation-seeking, sexual orientation and internalizing and externalizing problems were examined as correlates. Findings Approximately 43.5% of 15-17-year-olds had used at least one substance in the past 12 months. A 5-class model was identified: class 1 'abstainers' (67.3%), class 2 'alcohol users' (19.2%), class 3 'alcohol, marijuana and tobacco (AMTpredominant AM ) users' (8.2%), class 4 'alcohol, marijuana and tobacco (AMTpredominant T ) users' (3.9%) and class 5 'alcohol, marijuana, tobacco and other drug (AMTOD) users' (1.4%). Abstainers were considered the reference class. Higher sensation-seeking scores, higher age and lower academic grades were each associated with greater likelihood of membership in all user classes. Gender, race/ethnicity, parents/guardians' education, residence in non-urban areas and sexual minority groups were associated with membership in some, but not all, user classes. Compared with no/low/moderate severity, high severity internalizing problems were associated with membership in classes 2, 3 and 5, whereas high severity externalizing problems were associated with membership in classes 3 and 5 only. Conclusions There appear to be three heterogeneous polysubstance use classes among US youth aged 15-17 years. Correlates of substance use among US youth include higher sensation-seeking, poor academic performance, non-urban residence, minority sexual orientation and mental health problems.

Background While evidence suggests bidirectional associations between cigarette use and substance (alcohol or drug) use, how these associations are reflected across the range of currently available tobacco products is unknown. This study examined whether ever tobacco use predicted subsequent substance use, and ever substance use predicted subsequent tobacco use among 11,996 U.S. youth (12–17 years) from Waves 1 (2013–2014) and 2 (2014–2015) of the Population Assessment of Tobacco and Health (PATH) Study. Methods Ever use of cigarettes, e-cigarettes, traditional cigars, cigarillos, filtered cigars, pipe, hookah, snus pouches, smokeless tobacco excluding snus pouches, dissolvable tobacco, bidis, kreteks, alcohol, marijuana, prescription drugs, and other drugs (cocaine and other stimulants, heroin, inhalants, solvents, and hallucinogens) was assessed at Wave 1 followed by past 12-month use assessments at Wave 2. The analyses included covariates (demographics, mental health, sensation seeking, prior use) to mitigate confounding. Results Ever tobacco use predicted subsequent substance use. The magnitude of the associations was lowest for alcohol, higher for marijuana, and highest for other drugs. Ever substance use also predicted subsequent tobacco use. Specifically, ever alcohol, marijuana, and non-prescribed Ritalin/Adderall use predicted tobacco-product use. Ever e-cigarette and cigarette use exclusively and concurrently predicted subsequent any drug (including and excluding alcohol) use. E-cigarette and cigarette use associations in the opposite direction were also significant; the strongest associations were observed for exclusive cigarette use. Conclusion Tobacco and substance use prevention efforts may benefit from comprehensive screening and interventions across tobacco products, alcohol, and drugs, and targeting risk factors shared across substances.

© 2018 American Medical Association. All rights reserved. IMPORTANCE Cigarette marketing contributes to initiation of cigarette smoking among young people, which has led to restrictions on use of cigarette advertising. However, little is known about other tobacco advertising and progression to tobacco use in youth and young adults. OBJECTIVE To investigate whether receptivity to tobacco advertising among youth and young adults is associated with progression (being a susceptible never user or ever user) to use of the product advertised, as well as conventional cigarette smoking. DESIGN, SETTING, AND PARTICIPANTS The Population Assessment of Tobacco and Health (PATH) Study at wave 1 (2013-2014) and 1-year follow-up at wave 2 (2014-2015) was conducted in a US population-based sample of never tobacco users aged 12 to 24 years from wave 1 of the PATH Study (N = 10 989). Household interviews using audio computer-assisted self-interviews were conducted. EXPOSURES Advertising for conventional cigarettes, electronic cigarettes (e-cigarettes), cigars, and smokeless tobacco products at wave 1. MAIN OUTCOMES AND MEASURES Progression to susceptibility or ever tobacco use at 1-year follow-up in wave 2. RESULTS Of the 10 989 participants (5410 male [weighted percentage, 48.3%]; 5579 female [weighted percentage, 51.7%]), receptivity to any tobacco advertising at wave 1 was high for those aged 12 to 14 years (44.0%; 95%confidence limit [CL], 42.6%-45.4%) but highest for those aged 18 to 21 years (68.7%; 95%CL, 64.9%-72.2%). e-Cigarette advertising had the highest receptivity among all age groups. For those aged 12 to 17 years, susceptibility to use a product at wave 1 was significantly associated with product use at wave 2 for conventional cigarettes, e-cigarettes, cigars, and smokeless tobacco products. Among committed never users aged 12 to 17 years at wave 1, any receptivity was associated with progression toward use of the product at wave 2 (conventional cigarettes: adjusted odds ratio [AOR], 1.43; 95% CL, 1.23-1.65; e-cigarettes: AOR, 1.62; 95%CL, 1.41-1.85; cigars: AOR, 2.01; 95%CL, 1.62-2.49; and smokeless [males only]: AOR, 1.42; 95%CL, 1.07-1.89) and with use of the product (conventional cigarettes: AOR, 1.54; 95%CL, 1.03-2.32; e-cigarettes: AOR, 1.45; 95%CL, 1.19-1.75; cigars: AOR, 2.07; 95%CL, 1.26-3.40). Compared with those not receptive to any product advertising, receptivity to e-cigarette advertising, but not to cigarette advertising, was independently associated with those aged 12 to 21 years having used a cigarette at wave 2 (AOR, 1.60; 95%CL, 1.08-2.38). CONCLUSIONS AND RELEVANCE Receptivity to tobacco advertisingwas significantly associated with progression toward use in adolescents. Receptivity was highest for e-cigarette advertising and was associated with trying a cigarette.

OBJECTIVE: Research on the relationships between acculturation, ethnic identity, and oral health-related quality of life (OHRQOL) among the U.S. Hispanic/Latino population is sparse. The aim of this study is to examine the association between acculturation, ethnic identity, and OHRQOL among 13,172 adults in the 2008–2011 Hispanic Community Health Study/Study of Latinos (HCHS/SOL). DESIGN: Participants self-reported their acculturation (immigrant generation, birthplace, residence in the U.S., language, and social acculturation), ethnic identity (sense of belonging and pride), and four OHRQOL measures. Key socio-demographic, behavioral, and oral health outcomes were tested as potential confounders. RESULTS: Overall, 57% of individuals experienced poor OHRQOL in at least one of the domains examined. In multivariable analyses, some elements of higher acculturation were associated with greater food restriction and difficulty doing usual jobs/attending school, but not associated with pain or difficulty chewing, tasting, or swallowing. While sense of belonging to one’s ethnic group was not associated with poor OHRQOL, low sense of pride was associated with food restriction. Socio-behavioral characteristics were significant effect modifiers. CONCLUSION: This study contributes to the understanding of the role of Hispanic/Latino’s cultural factors in OHRQOL perception and can inform targeted strategies to improve OHRQOL in this diverse population.

Objectives Maternal periodontal disease is associated with adverse perinatal outcomes. Anxiety and depression adversely impact oral health in nonpregnant women; however, this association has not been evaluated during pregnancy, a time characterized by higher rates of anxiety and depression. Therefore, we examined the association between these factors and oral disease and oral healthcare utilization among 402 pregnant respondents to the 2010 Behavioral Risk Factor Surveillance System. Methods Self-reported lifetime diagnoses of anxiety, depression, and current depression were assessed. Oral health outcomes included self-reported tooth loss and dental visits in the past year. Results One-fifth (21.2 percent) of respondents reported a tooth loss and 32.5 percent reported nonuse of oral health services. The prevalence of lifetime diagnosed anxiety and depression was 13.6 percent and 11.3 percent, respectively, whereas 10.6 percent reported current depression. After adjusting for risk factors, pregnant women with diagnosed anxiety had increased odds of one or more tooth loss [odds ratio (OR) = 3.30; 95 percent confidence interval (CI): 1.01-10.77] compared with those without the disorder. Similarly, after adjusting for socioeconomic factors, women with anxiety had increased odds of nonuse of oral health services (OR = 2.67; 95 percent CI: 1.03-6.90); however, this was no longer significant after adjusting for health behaviors and body mass index. We observed no significant association with depression. Conclusions In this population-based sample, we found a two- to threefold increased odds of tooth loss and nonuse of oral health services among pregnant women with a lifetime diagnosis of anxiety. To our knowledge, this is the first study to examine these associations among pregnant women.

Excess weight is an epidemic problem in the United States, with 69.2% of the adult population overweight or obese (Ogden, Carroll, Kit, & Flegal, 2014). Prepregnancy obesity has been associated with increased risk of adverse pregnancy and birth outcomes including gestational hypertension, preeclampsia, and macrosomia, and, for the infant, increased risk of obesity later in life (Papachatzi, Dimitriou, Dimitropoulos, & Vantarakis, 2013; Patro et al., 2013; Sarwer, Allison, Gibbons, Markowitz, & Nelson, 2006). Gestational weight gain (GWG) guidelines are based on prepregnancy Body Mass Index (BMI), with overweight and obese women encouraged to gain less weight during pregnancy compared to normal and underweight women (Institute of Medicine and National Research Council, 2009). Hispanic mothers are more likely to begin their pregnancies overweight or obese compared to non-Hispanic White women (Kieffer et al., 2006). While obesity predicts depression and elevated depressive symptoms in nonpregnant women (Luppino et al., 2010), studies in the perinatal period are sparse. However, prenatal depression is common: occurring in up to 18% of women in the United States (Gavin et al., 2005), and up to 33% of Hispanic women in the United States (Chasan-Taber et al., 2010). Given current societal pressure in the United States to be thin, overweight women and those who gain excess weight may experience high levels of body dissatisfaction, which has been linked to depression (Clark, Skouteris, Wertheim, Paxton, & Milgrom, 2009). Our objective was to assess the association between prepregnancy BMI, GWG, and elevated depressive symptoms during pregnancy in a Hispanic cohort. We hypothesized that women who were overweight, obese, or gained more than the recommended amount of weight during pregnancy would experience elevated depressive symptoms during pregnancy.

Aim—Prior literature suggests a positive association between psychosocial stress and the risk of diabetes in non-pregnant populations, but studies during pregnancy are sparse. We evaluated the relationship between stress and glucose intolerance among 1115 Hispanic (predominantly Puerto Rican) prenatal care patients in Proyecto Buena Salud, a prospective cohort study in Western Massachusetts (2006–2011). Methods—Cohen’s Perceived Stress Scale (PSS-14) was administered in early (mean = 12.3 weeks gestation; range 4.1–18 weeks) and mid-(mean = 21.3 weeks gestation; range 18.1–26 weeks) pregnancy. Participants were classified as having a pregnancy complicated by gestational diabetes mellitus, impaired glucose tolerance, and abnormal glucose tolerance, based on the degree of abnormality on glucose tolerance testing between 24 and 28 weeks of gestation. Results—The prevalence of gestational diabetes mellitus, impaired glucose tolerance, and abnormal glucose tolerance was 4.1%, 7.2%, and 14.5%, respectively. Absolute levels of early or mid-pregnancy stress were not significantly associated with glucose intolerance. However, participants with an increase in stress from early to mid-pregnancy had a 2.6-fold increased odds of gestational diabetes mellitus (95% confidence intervals: 1.0–6.9) as compared to those with no change or a decrease in stress after adjusting for age and pre-pregnancy body mass index. In addition, every one-point increase in stress scores was associated with a 5.5 mg/dL increase in screening glucose level (β = 5.5; standard deviation = 2.8; P = 0.05), after adjusting for the same variables. Conclusion—In this population of predominantly Puerto Rican women, stress patterns during pregnancy may influence the risk of glucose intolerance.

Introduction Waterpipe use is common among U.S. young adults (aged 18–24 years), with estimates considerably higher than other age groups. Although studies have examined attitudes and beliefs associated with waterpipe use, no study has examined reasons for use in a nationally representative sample. Methods Using latent class analyses, this study examined subgroups based on self-reported reasons for use of past 30-day young adult (aged 18–24 years) waterpipe users (n=1,198) from Wave 1 (2013–2014) of the Population Assessment of Tobacco and Health Study. Data analyses were conducted in 2017. Covariates included sociodemographic characteristics, substance use, and internalizing and externalizing problems. Results A three-class model was identified: Class 1 (socializing and flavors, 57%), Class 2 (many reasons [flavors, socializing, less harmful than cigarettes, and affordability], 20%), and Class 3 (socializing, 23%). Class 3 was considered the referent group. Compared with non-Hispanic whites, non-Hispanic blacks were less likely to belong to Class 1, whereas Hispanics were more likely to belong to Class 2. Compared with less than high school education, greater than high school education was associated with membership in Class 1; however, high school graduation was associated with membership in Class 2. Past-year alcohol users compared with non-users were less likely to belong to Class 2. Past 30-day poly-tobacco users compared with non-users were more likely to belong to Class 2. Conclusions This study revealed distinct classes of waterpipe users based on self-reported reasons for use. Findings inform targeted policies for waterpipe tobacco control as part of public health efforts to mitigate harms associated with tobacco use.

Introduction Tobacco and obesity are leading contributors to mortality in the United States. Due to emerging changes in youth tobacco use, further examination of co-occurrence of these issues is warranted. Methods This study examined associations between body mass index (BMI) and tobacco-product use and whether these varied by gender in a nationally representative sample of 12,416 Wave 1 (2013–2014) U.S. youth (12–17 years) from the Population Assessment of Tobacco and Health Study. Multivariable logistic regression analyses examined the odds of past 30-day tobacco-product use according to BMI. BMI was analyzed categorically using the Centers for Disease Control and Prevention (CDC) BMI-for-age weight status categories (underweight/healthy weight, overweight, and obese) and as a continuous variable. Results Youth classified as overweight or obese were not more likely to use any tobacco, cigarettes, e-cigarettes, any cigar, or hookah. However, youth who were obese were more likely to use smokeless tobacco (Adjusted Odds Ratio (AOR) = 1.68, 95% Confidence Interval (CI): 1.01, 2.81). There were no significant gender interactions for these associations. When BMI was analyzed continuously, a 5-unit and 10-unit increase was significantly associated with using any tobacco, cigarettes, any cigar, and smokeless tobacco. This linear association was supported by similar results for a log-transformed BMI variable. Conclusions Findings suggest a continuum between weight increase and tobacco-product use among American youth. Clinicians should consider screening for tobacco use among youth who gain weight within any weight class, not just those considered overweight or obese.

Although non-cigarette tobacco product use is increasing among U.S. adults, their associations with substance use and mental health problems are unclear. This study examined co-occurrence of tobacco use, substance use, and mental health problems, and its moderation by gender, among 32,202U.S. adults from Wave 1 (2013-2014) of the nationally representative longitudinal Population Assessment of Tobacco and Health (PATH) Study.Participants self-reported current cigarette, e-cigarette, traditional cigar, cigarillo, filtered cigar, hookah, smokeless tobacco and other tobacco product use; past year alcohol, marijuana, and other drug use; and past year substance use, internalizing and externalizing problems.Compared to non-current tobacco users, current users were more likely to report alcohol or drug use (adjusted odds ratio (AOR)=2.6; 95% confidence interval (CI): 2.3, 2.9), with the strongest associations observed for cigarillo and hookah users. Across all tobacco product groups, users were more likely to report internalizing (AOR=1.9; 95% CI: 1.7, 2.1), externalizing (AOR=1.6; 95% CI: 1.5, 1.8), and substance use (AOR=3.4; 95% CI: 2.9, 4.1) problems than non-users. Gender moderated many of these associations and, of these, all non-cigarette tobacco product associations were stronger among females.This nationally representative study of U.S. adults is the first to comprehensively document tobacco use, substance use, and mental health comorbidities across the range of currently available tobacco products, while also demonstrating that female tobacco users are at increased risk for substance use and mental health problems. These findings may point to gender differences in vulnerability and suggest that interventions incorporate gender-specific approaches.

Women diagnosed with abnormal glucose tolerance and gestational diabetes mellitus are at increased risk for subsequent type 2 diabetes, with higher risks in Hispanic women. Studies suggest that physical activity may be associated with a reduced risk of these disorders; however, studies in Hispanic women are sparse.We prospectively evaluated this association among 1241 Hispanic participants in Proyecto Buena Salud. The Pregnancy Physical Activity Questionnaire was used to assess pre, early, and mid pregnancy physical activity. Medical records were abstracted for pregnancy outcomes.A total of 175 women (14.1%) were diagnosed with abnormal glucose tolerance and 57 women (4.6%) were diagnosed with gestational diabetes. Increasing age and body mass index were strongly and positively associated with risk of gestational diabetes. We did not observe statistically significant associations between total physical activity or meeting exercise guidelines and risk. However, after adjusting for age, BMI, gestational weight gain, and other important risk factors, women in the top quartile of moderate-intensity activity in early pregnancy had a decreased risk of abnormal glucose tolerance (odds ratio=0.48, 95% Confidence Interval 0.27-0.88, Ptrend=0.03) as compared to those in the lowest quartile. Similarly, women with the highest levels of occupational activity in early pregnancy had a decreased risk of abnormal glucose tolerance (odds ratio=0.48, 95% Confidence Interval 0.28-0.85, Ptrend=0.02) as compared to women who were unemployed.In this Hispanic population, total physical activity and meeting exercise guidelines were not associated with risk. However, high levels of moderate-intensity and occupational activity were associated with risk reduction.

Key Points Question What is the association between first flavored use of a given tobacco product and subsequent tobacco use, including progression of tobacco use, among US youth (aged 12-17 years), young adults (aged 18-24 years), and adults (aged ≥25 years)? Findings In this cohort study of 11 996 youth and 26 447 adults who participated in waves 1 and 2 of the Population Assessment of Tobacco and Health Study, most youth and young adult new tobacco users first tried a flavored product. First use of flavored tobacco products was positively associated with subsequent product use compared with first use of a nonflavored product. Meaning First use of flavored tobacco products may place youth and adults at risk of subsequent tobacco use., This cohort study uses data from the Population Assessment of Tobacco and Health (PATH) Study to examine whether first use of flavored tobacco products is associated with subsequent tobacco use among US youth and adults., Importance Flavors in tobacco products may appeal to young and inexperienced users. Objective To examine among youth (aged 12-17 years), young adults (aged 18-24 years), and adults (aged ≥25 years) the prevalence of first use of flavored tobacco products among new tobacco users and the association between first flavored use of a given tobacco product and tobacco use 1 year later, including progression of tobacco use. Design, Setting, and Participants This cohort study represents a longitudinal analysis of data from the Population Assessment of Tobacco and Health (PATH) Study, a nationally representative study with data collected in 2013 to 2014 (wave 1) and 2014 to 2015 (wave 2). Participants were noninstitutionalized individuals, including 11 996 youth and 26 447 adults, in selected households who participated in both waves of the PATH Study. Data analysis was conducted from July 2016 to June 2019. Main Outcomes and Measures Prevalence of tobacco product use at wave 2. Results The mean (SE) age of the participants was 14.5 (0.0) years for youth, 21.1 (0.0) years for young adults, and 50.3 (0.0) for adults. Most youth (71.9%; 95% CI, 69.7%-74.0%) and young adults (57.6%; 95% CI, 54.9%-60.3%) who were new users of tobacco products over the 10- to 13-month follow-up period used flavored products. First use of a menthol or mint or other flavored cigarette documented at wave 1 was positively associated with past 12-month and past 30-day cigarette use in all age groups at wave 2 compared with first use of a nonflavored cigarette (youth, flavored cigarette, past 12-month use adjusted prevalence ratio [aPR], 1.14 [95% CI, 1.05-1.25] and past 30-day use aPR, 1.15 [95% CI, 1.00-1.31]; youth, menthol or mint cigarette, past 12-month use aPR, 1.18 [95% CI, 1.08-1.29] and past 30-day use aPR, 1.19 [95% CI, 1.04-1.37]; young adult, flavored cigarette, past 12-month use aPR, 1.09 [95% CI, 1.04-1.15] and past 30-day use aPR, 1.13 [95% CI, 1.06-1.21]; young adult menthol or mint cigarette, past 12-month use aPR, 1.10 [95% CI, 1.05-1.16] and past 30-day use aPR, 1.15 [95% CI, 1.07-1.23]; adult flavored cigarette, past 12-month use aPR, 1.10 [95% CI, 1.05-1.15] and past 30-day use aPR, 1.09 [95% CI, 1.04-1.14]; adult menthol or mint cigarette, past 12-month use aPR, 1.13 [95% CI, 1.08-1.18] and past 30-day use aPR, 1.12 [95% CI, 1.07-1.17]). Among young adults, first use of flavored e-cigarettes (aPR, 2.05; 95% CI, 1.61-2.61), any cigars (aPR, 1.60; 95% CI, 1.26-2.02), cigarillos (aPR, 1.49; 95% CI, 1.08-2.05), filtered cigars (aPR, 3.69; 95% CI, 2.08-6.57), hookah (aPR, 1.91; 95% CI, 1.23-2.98), and any smokeless tobacco (aPR, 1.54; 95% CI, 1.08-2.20) was prospectively associated with current regular use of those products at wave 2 compared with first nonflavored use. Among adults aged 25 years and older, first use of flavored e-cigarettes (aPR, 1.60; 95% CI, 1.41-1.82), any cigars (aPR, 1.56; 95% CI, 1.29-1.87), cigarillos (aPR, 1.29; 95% CI, 1.01-1.64), filtered cigars (aPR, 1.79; 95% CI, 1.25-2.54), hookah (aPR, 5.66; 95% CI, 2.04-15.71), and any smokeless tobacco (aPR, 1.55; 95% CI, 1.32-1.82) was prospectively associated with current regular use of those products at wave 2 compared with first nonflavored use. Conclusions and Relevance In this longitudinal cohort study, flavors in tobacco products were associated with youth and young adult tobacco experimentation. First use of a flavored tobacco product may place youth, young adults, and adults at risk of subsequent tobacco use.

BackgroundMost youth and young adult (YA) tobacco users use flavoured products; however, little is known about specific flavours used.MethodsWe report flavour types among US tobacco users from the Population Assessment of Tobacco and Health Study, wave 2, 2014–2015. At wave 2, we examined (1) flavour use and type at past 30-day use; (2) new flavoured tobacco product use and type; (3) product-specific flavour patterns across youth (ages 12–17) (n=920), YA (18–24) (n=3726) and adult (25+) (n=10 346) past 30-day and new tobacco users and (4) concordance between self-coded and expert-coded brand flavour type among all adults (18+).ResultsPrevalence of flavoured tobacco product use was highest among youth, followed by YA and adult 25+ any tobacco users. Within each age group, flavoured use was greatest among hookah, e-cigarette and snus users. Overall, menthol/mint, fruit and candy/sweet were the most prevalent flavour types at first and past 30-day use across age groups. For past 30-day use, all flavour types except menthol/mint exhibited an inverse age gradient, with more prevalent use among youth and YAs, followed by adults 25+. Prevalence of menthol/mint use was high (over 50% youth, YAs; 76% adults 25+) and exhibited a positive age gradient overall, though the reverse for cigarettes. Brand-categorised and self-reported flavour use measures among adults 18+ were moderately to substantially concordant across most products.ConclusionsCommon flavours like menthol/mint, fruit and candy/sweet enhance appeal to young tobacco users. Information on flavour types used by product and age can inform tobacco flavour regulations to addess flavour appeal especially among youth.

The aim of this study is to prospectively examine the association between maternal depressive symptoms in early pregnancy and risk of abnormal glucose tolerance (AGT) and impaired glucose tolerance (IGT) in mid-pregnancy. We evaluated this association among 934 participants in Proyecto Buena Salud, a prospective cohort study of Hispanic (predominantly Puerto Rican) women in Western Massachusetts. Depressive symptoms were assessed in early pregnancy using the 10-item Edinburgh Postnatal Depression Scale. Scores ≥13 indicated at least probable minor depression and scores ≥15 indicated probable major depression. AGT and IGT were diagnosed using American Diabetes Association criteria. In early pregnancy, 247 (26.5 %) participants experienced at least minor depression and 163 (17.4 %) experienced major depression. A total of 123 (13.2 %) were classified with AGT and 56 (6.0 %) were classified with IGT. In fully-adjusted models, the odds ratio for AGT associated with minor depression was 1.20 (95 % CI 0.77-1.89) and for major depression was 1.34 (95 % CI 0.81-2.23). The odds ratio for IGT associated with minor depression was 1.22 (95 % CI 0.62-2.40) and for major depression was 1.53 (95 % CI 0.73-3.22). We did not observe an association with continuous screening glucose measures. Findings in this prospective cohort of Hispanic women did not indicate a statistically significant association between minor or major depression in early pregnancy and AGT or screening glucose values in mid-pregnancy. Due to the small number of cases of IGT, our ability to evaluate the association between depression and IGT risk was constrained.

Objective Hispanic women have high rates of excessive and inadequate gestational weight gain (GWG) according to Institute of Medicine (IOM) guidelines. Observational studies suggest that physical activity may be associated with GWG but have been conflicting and were largely conducted in non-Hispanic white populations. Methods The association between physical activity and compliance with GWG guidelines, total GWG, and rate of GWG among 1,276 Hispanic participants in Proyecto Buena Salud, a cohort study in Western Massachusetts was prospectively evaluated. The Pregnancy Physical Activity Questionnaire was used to assess pre, early, mid, and late pregnancy physical activity according to both intensity (i.e., sedentary, moderate, and vigorous) and type (i.e., housework/caregiving, occupational, and sports/exercise). Results A total of 26.9% of women gained within IOM guidelines, 21.2% had inadequate GWG, and 51.9% experienced excessive GWG. Overall, we did not observe statistically significant associations between type or intensity of physical activity during pre, early, mid, and late pregnancy and inadequate or excessive GWG, total GWG, or rate of GWG. Conclusions In this prospective cohort study of Hispanic women, after controlling for important risk factors, pregnancy physical activity did not appear to be associated with GWG.

Suicide rates among American Indian and Alaska Native (AI/AN) young people are significantly higher than other ethnic groups in the United States. Not only are there great differences when comparing AI/AN rates and those of other Americans, some tribal groups have very low rates of suicide while other Native communities have much higher rates. Despite this obvious variability, there is little research to help understand the factors associated with these differences. The current study considers the correlates of suicidal behavior in one rural Alaska Native region that suffers disproportionately from suicide. The analysis describes suicide behavior between the years 2001-2009, and considers the characteristics associated with both suicide deaths and nonfatal suicidal behavior. In multivariate analyses we identified gender, method of suicide and history of previous attempt as significant predictors of fatal suicide behavior, similar to results obtained from analyses on the same community's data from the previous decade. This descriptive study can offer some insights to shape prevention efforts in this and other rural, tribal communities.

Background:Physical activity during pregnancy is associated with reduced risk of adverse maternal and fetal outcomes. However, the majority of pregnant women are inactive and interventions designed to increase exercise during pregnancy are sparse. We evaluated the feasibility and preliminary efficacy of an exercise intervention among a diverse sample of pregnant women.Methods:The B.A.B.Y. (Behaviors Affecting Baby and You) Study is conducted at a large tertiary care facility in Western Massachusetts. We randomized 110 prenatal care patients (60% Hispanic) to an individually tailored 12-week exercise intervention arm (n = 58) or to a health and wellness control arm (n = 52) at mean = 11.9 weeks gestation. Physical activity was assessed via the Pregnancy Physical Activity Questionnaire (PPAQ).Results:After the 12-week intervention, the exercise arm experienced a smaller decrease (−1.0 MET-hrs/wk) in total activity vs. the control arm (−10.0 MET-hrs/wk; P = .03), and a higher increase in sports/exercise (0.9 MET-hrs/wk) vs. the control arm (−0.01 MET-hrs/wk; P = .02). Intervention participants (95%) reported being satisfied with the amount of information received and 86% reported finding the study materials interesting and useful.Conclusions:Findings support the feasibility and preliminary efficacy of a tailored exercise intervention in increasing exercise in a diverse sample of pregnant women.

Introduction This study assessed patterns of e-cigarette and cigarette use from Wave 1 to Wave 2 among adult e-cigarette users at Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study. Methods We examined changes in e-cigarette use frequency at Wave 2 among adult e-cigarette users at Wave 1 (unweighted n=2835). Adjusted prevalence ratios (aPR) were calculated using a predicted marginal probability approach to assess correlates of e-cigarette discontinuance and smoking abstinence at Wave 2. Results Half (48.8%) of adult e-cigarette users at Wave 1 discontinued their use of e-cigarettes at Wave 2. Among dual users of e-cigarettes and cigarettes at Wave 1, 44.3% maintained dual use, 43.5% discontinued e-cigarette use and maintained cigarette smoking and 12.1% discontinued cigarette use at Wave 2, either by abstaining from cigarette smoking only (5.1%) or discontinuing both products (7.0%). Among dual users at Wave 1, daily e-cigarette users were more likely than non-daily users to report smoking abstinence at Wave 2 (aPR=1.40, 95% CI 1.02 to 1.91). Using a customisable device (rather than a non-customisable one) was not significantly related to smoking abstinence at Wave 2 (aPR=1.14, 95% CI 0.81 to 1.60). Conclusions This study suggests that e-cigarette use patterns are highly variable over a 1-year period. This analysis provides the first nationally representative estimates of transitions among US adult e-cigarette users. Future research, including additional waves of the PATH Study, can provide further insight into long-term patterns of e-cigarette use critical to understanding the net population health impact of e-cigarettes in USA.

Maternal depression increases risk of adverse perinatal outcomes, and recent evidence suggests that body image may play an important role in depression. This systematic review identifies studies of body image and perinatal depression with the goal of elucidating the complex role that body image plays in prenatal and postpartum depression, improving measurement, and informing next steps in research. We conducted a literature search of the PubMed database (1996– 2014) for English language studies of (1) depression, (2) body image, and (3) pregnancy or postpartum. In total, 19 studies matched these criteria. Cross-sectional studies consistently found a positive association between body image dissatisfaction and perinatal depression. Prospective cohort studies found that body image dissatisfaction predicted incident prenatal and postpartum depression; findings were consistent across different aspects of body image and various pregnancy and postpartum time periods. Prospective studies that examined the reverse association found that depression influenced the onset of some aspects of body image dissatisfaction during pregnancy, but few evaluated the postpartum onset of body image dissatisfaction. The majority of studies found that body image dissatisfaction is consistently but weakly associated with the onset of prenatal and postpartum depression. Findings were less consistent for the association between perinatal depression and subsequent body image dissatisfaction. While published studies provide a foundation for understanding these issues, methodologically rigorous studies that capture the perinatal variation in depression and body image via instruments validated in pregnant women, consistently adjust for important confounders, and include ethnically diverse populations will further elucidate this association.

Maternal periodontal disease is associated with adverse perinatal outcomes. Anxiety and depression adversely impact oral health in nonpregnant women; however, this association has not been evaluated during pregnancy, a time characterized by higher rates of anxiety and depression. Therefore, we examined the association between these factors and oral disease and oral healthcare utilization among 402 pregnant respondents to the 2010 Behavioral Risk Factor Surveillance System.Self-reported lifetime diagnoses of anxiety, depression, and current depression were assessed. Oral health outcomes included self-reported tooth loss and dental visits in the past year.One-fifth (21.2 percent) of respondents reported a tooth loss and 32.5 percent reported nonuse of oral health services. The prevalence of lifetime diagnosed anxiety and depression was 13.6 percent and 11.3 percent, respectively, whereas 10.6 percent reported current depression. After adjusting for risk factors, pregnant women with diagnosed anxiety had increased odds of one or more tooth loss [odds ratio (OR) = 3.30; 95 percent confidence interval (CI): 1.01-10.77] compared with those without the disorder. Similarly, after adjusting for socioeconomic factors, women with anxiety had increased odds of nonuse of oral health services (OR = 2.67; 95 percent CI: 1.03-6.90); however, this was no longer significant after adjusting for health behaviors and body mass index. We observed no significant association with depression.In this population-based sample, we found a two- to threefold increased odds of tooth loss and nonuse of oral health services among pregnant women with a lifetime diagnosis of anxiety. To our knowledge, this is the first study to examine these associations among pregnant women.

Prior studies of the association between physical activity and hypertensive disorders of pregnancy have been conflicting; the majority focused on leisure-time activity only, did not use physical activity questionnaires validated for pregnancy, and were conducted in primarily non-Hispanic white populations.We prospectively evaluated this association among 1240 Hispanic women in Proyecto Buena Salud. The Pregnancy Physical Activity Questionnaire, validated for use in pregnancy, was used to assess pre- and early pregnancy sports/exercise, household/caregiving, occupational and transportation activity. Diagnoses of hypertensive disorders of pregnancy were based on medical record abstraction and confirmed by the study obstetrician.A total of 49 women (4.0%) were diagnosed with a hypertensive disorder of pregnancy, including 32 women (2.6%) with pre-eclampsia. In age-adjusted analyses, high levels of early pregnancy household/caregiving activity were associated with reduced risk of total hypertensive disorders (OR = 0.4, 95% CI 0.1-0.9) and pre-eclampsia (OR = 0.3, 95% CI 0.1-0.9) relative to low levels; however, these findings were no longer statistically significant in multivariable models. Pre-pregnancy activity and pattern of activity from pre- to early-pregnancy were not significantly associated with risk. Finally, sedentary behavior was not significantly associated with hypertensive disorders.Findings from this prospective study of Hispanic women were consistent with those of prior prospective cohorts indicating that physical activity prior to and during early pregnancy does not significantly reduce risk of hypertensive disorders of pregnancy.

Testing for systemic diseases in dental clinics is a potentially attractive avenue for oral health professionals and may be viewed as an opportunity to increase professional reach, expand practice, and improve financial returns. However, several ethical questions arise that must be addressed before such activities are adopted. (1) What should be the level of training dentists must acquire to deal with challenges associated with testing? (2) How well are dental practices aware of and compliant with the Health Insurance Portability and Accountability Act and procedures related to informed consent? (3) What is the evidence regarding acceptability and effectiveness of testing? (4) What should be the acceptable standard of practice for conduct of invasive and noninvasive tests? (5) What is the boundary delineating "testing" and "reporting" vis-a-vis counseling? (6) What is the value of testing without counseling? (7) What assurances need to be in place to ensure voluntariness of testing? (8) How would data from testing be used in "research," especially with the growth of practice based research networks? and (9) Does the American Dental Association Code of Ethics need to incorporate guidance for practicing dentists? We discuss how ethical principles can be used to develop a framework of guidelines for potential testing for systemic diseases in dental clinics..
