Objective: To examine the association of social support with dental caries experience in Hispanics/Latinos living in the United States (US) and to assess whether the relationship is modified by nativity status. Methods: This cross‐sectional study analysed data for 4459 dentate men and women aged 18‐74 years in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study. At baseline (2008‐2011), dentists quantified dental caries experience as the number of decayed, missing, and filled permanent tooth surfaces (DMFS) for all teeth excluding third molars. Social support was assessed according to measures of structural support (Social Network Index) and functional support (Interpersonal Support Evaluation List). Covariate‐adjusted multiple linear regression estimated the relationship between social support and dental caries experience and tested whether the association was modified by nativity status (born within the 50 US states, foreign‐born <10 years in the United States, foreign‐born >10 years or more in the United States). Results: In covariate‐adjusted models, each additional role in the social network was associated with 1.39 fewer DMF tooth surfaces (95% CI: −2.21, −0.58) among foreign‐born Hispanics/Latinos with fewer than 10 years lived in the US. For foreign‐born Hispanics/Latinos with 10 years or more in the United States, each additional social network role was associated with 0.57 fewer DMF tooth surfaces (95% CI: −1.19, 0.04). No association was observed between functional social support and dental caries experience regardless of nativity status. Conclusions: Our findings suggest that structural social support is protective against dental caries experience among recent immigrants of Hispanic/Latino background. This association may reflect the importance of social support to integration into the medical and dental infrastructure and thus receipt of dental care. Future research that examines the behavioural and cultural factors that moderate the relationship between social support and dental caries experience will inform development of culturally sensitive dental caries prevention programs for Hispanics/Latinos in the United States.

The authors' aim was to examine the association between sugar-sweetened beverage (SSB) consumption and the prevalence and severity of the caries experience in children and adults in the United States. The authors analyzed data obtained from 14,192 people aged 2 through 74 years, who participated in the National Health and Nutrition Examination Survey from 2011 through 2014. Using descriptive analyses, the authors assessed the distributions of sociodemographic characteristics overall and via SSB intake. The authors used multivariable logistic regression to estimate the association of untreated and severe untreated caries with SSB consumption in all age groups. Across all ages, male participants were more likely than female participants to consume SSBs, and consumption was higher in non-Hispanic black and Hispanic populations. Relative to those who did not consume SSBs, people aged 20 through 44 years who consumed SSBs had significantly higher odds of having untreated caries (adjusted odds ratio [AOR], 1.27; 95% confidence interval [CI], 1.04 to 1.55) and severe untreated caries (AOR, 1.36; 95% CI, 1.15 to 1.60). Adolescents aged 9 through 19 years had significantly higher odds of having untreated caries (AOR, 1.37; 95% CI, 1.05 to 1.80), and middle-aged adults (45-64 years) had significantly higher odds of severe untreated caries (AOR, 1.46; 95% CI, 1.10 to 1.92) relative to those who did not consume SSBs. Consumption of SSBs was associated with increased caries experience among young children and increased risk of developing untreated caries in all age groups of children and adults. Continued efforts by policy makers, public health leaders, and clinicians to reduce consumption of SSBs across the life span are paramount. [ABSTRACT FROM AUTHOR]

Objective: Recent reports have documented health disparities according to sexual orientation and used the minority stress model as a framework for understanding their origins. To date, however, sexual orientation-related disparities in the oral health domain have not been evaluated. Accordingly, this study sought to investigate potential health disparities in objectively-assessed and subjective reports of oral heath among lesbian, gay, and bisexual adults relative to the heterosexual community-dwelling US population.Methods: We used three consecutive cycles (2009-2014) of National Health and Nutrition Examination Survey (NHANES) data for men and women aged 18-59 years. We examined clinical measures of dental caries, tooth loss, chronic periodontitis, and oral human papillomavirus (HPV) as well as subjective reports of oral health status and use of dental services.Results: Clinical measures of oral disease did not differ according to sexual orientation; however, bisexual adults were more likely to rate their oral health unfavorably (41%) than heterosexual adults (27%). Gay men reported "bone loss around teeth" more frequently (35%) than heterosexual (11%) and bisexual (10%) men. Bisexual individuals were more likely to confront barriers to accessing dental care (30%) versus heterosexual adults (19%).Conclusions: While clinical measures of oral health did not substantially differ between sexual orientation strata, subjective measures of oral health were worse among gay, lesbian, and bisexual adults versus heterosexual adults. Further study of the psychosocial construction of oral health among sexual minorities is warranted. [ABSTRACT FROM AUTHOR]

Background. Despite supporting scientific evidence, community water fluoridation (CWF) often fails in public referenda. To understand why, the authors quantitatively analyzed text from news media coverage of CWF referenda. Methods. The authors analyzed text from 234 articles covering 11 CWF referenda conducted in 3 US cities from 1956 through 2013. The authors used cluster analysis to identify each article's core rhetoric and classified it according to sentiment and tone. The authors used multilevel count regression models to measure the use of positive and negative words regarding CWF. Results. Media coverage more closely resembled core rhetoric used by fluoridation opponents than the rhetoric used by fluoridation proponents. Despite the scientific evidence, the media reports were balanced in tone and sentiment for and against CWF. However, in articles emphasizing children, greater negative sentiment was associated with CWF rejection. Conclusions. Media coverage depicted an artificial balance of evidence and tone in favor of and against CWF. The focus on children was associated with more negative tone in cities where voters rejected CWF. Practical Implications. When speaking to the media, advocates for CWF should emphasize benefits for children and use positive terms about dental health rather than negative terms about dental disease.

Introduction: This study's purpose is to determine whether nonconsumption of tap water is associated with lower prevalence of elevated blood lead levels and higher prevalence of dental caries in children and adolescents.Methods: Cross-sectional data from the National Health and Nutrition Examination Survey 2005-2014 recorded drinking water source (n=15,604) and blood lead levels (n=12,373) for participants aged 2-19 years, and dental caries experience for the 2011-2014 subset (n=5,677). The threshold for elevated blood lead level was ≥3 μg/dL. A binary outcome indicated presence or absence of dental caries experience. Multivariable generalized linear models estimated adjusted prevalence ratios with 95% confidence limits.Results: In analysis conducted in 2017, 15% of children and adolescents did not drink tap water, 3% had elevated blood lead levels ≥3 μg/dL, and 50% had dental caries experience. Children and adolescents who did not drink water were less likely than tap water drinkers to have an elevated blood lead level (adjusted prevalence ratios=0.62, 95% confidence limits=0.42, 0.90). Nonconsumers of tap water were more likely to have dental caries (adjusted prevalence ratios=1.13, 95% confidence limits=1.03, 1.23). Results persisted after adjustment for other covariates and using a higher threshold for elevated blood lead level.Conclusions: In this nationally representative U.S. survey, children and adolescents who did not drink tap water had lower prevalence of elevated blood lead levels and higher prevalence of dental caries than those who drank tap water.

Objective To describe self-reported exposure to environmental tobacco smoke ( ETS) and its association with periodontitis prevalence in a diverse group of Hispanics/Latinos. Methods Data came from 8675 lifetime nonsmokers in the 2008-2011 Hispanic Community Health Study/Study of Latinos. Exposure to ETS was self-reported, while periodontitis was defined using the Centers for Disease Control and Prevention-American Academy of Periodontology criteria and the proportion of sites affected by clinical attachment level of ≥3 mm or pocket depth of ≥4 mm. Survey logistic regression estimated prevalence odds ratios ( POR) and 95% confidence intervals ( CI). In addition, we assessed whether greater hours of exposure to ETS in the past year was associated with greater periodontitis prevalence, and lastly, we conducted a simple sensitivity analysis of ETS misclassification. Results Age-standardized prevalence estimates (95% CI) for ETS exposure and periodontitis were 57.6% (55.9, 59.4) and 39.8% (38.1, 41.4), respectively. After adjusting for confounders and periodontitis risk factors, we estimated an overall adjusted POR (95% CI) for the ETS-periodontitis association as 1.09 (0.95-1.26) with a confidence limit ratio ( CLR) of 1.34. This association varied in magnitude by Hispanic/Latino background, ranging from 1.04 (0.75, 1.43 with a CLR = 1.91) among Central Americans to 1.76 (1.16, 2.66 with a CLR = 2.29) in Puerto Ricans. Conclusions Previously reported associations between ETS and periodontitis appear weak in this study. However, the magnitude of the association differs according to Hispanic/Latino background.

Background. Hispanics and Latinos are an ethnically heterogeneous population with distinct oral health risk profiles. Few study investigators have examined potential variation in the burden of periodontitis according to Hispanic or Latino background. Methods. The authors used a multicenter longitudinal populationbased cohort study to examine the periodontal health status at screening (2008-2011) of 14,006 Hispanic and Latino adults, aged 18 to 74 years, from four U.S. communities who self-identified as Cuban, Dominican, Mexican, Puerto Rican, Central American or South American. The authors present weighted, age-standardized prevalence estimates and corrected standard errors of probing depth (PD), attachment loss (AL) and periodontitis classified according to the case definition established by the Centers for Disease Control and Prevention and the American Academy of Periodontology (CDC-AAP). The authors used a Wald χ:2 test to compare prevalence estimates across Hispanic or Latino background, age and sex. Results. Fifty-one percent of all participants had exhibited total periodontitis (mild, moderate or severe) per the CDC-AAP classification. Cubans and Central Americans exhibited the highest prevalence of moderate periodontitis (39.9 percent and 37.2 percent, respectively). Across all ages, Mexicans had the highest prevalence of PD across severity thresholds. Among those aged 18 through 44 years, Dominicans consistently had the lowest prevalence of AL at all severity thresholds. Conclusions. Measures of periodontitis varied significantly by age, sex and Hispanic or Latino background among the four sampled Hispanic Community Health Study/Study of Latinos communities. Further analyses are needed to account for lifestyle, behavioral, demographic and social factors, including those related to acculturation. Practical Implications. Aggregating Hispanics and Latinos or using estimates from Mexicans may lead to substantial underestimation or overestimation of the burden of disease, thus leading to errors in the estimation of needed clinical and public health resources. This information will be useful in informing decisions from public health planning to patient-centered risk assessment. [ABSTRACT FROM AUTHOR]

Objectives. We investigated the relationship between secondhand smoke and periodontal disease in nonsmokers. Methods. We undertook a cross-sectional analysis of the Atherosclerosis Risk in Communities study with 2739 lifetime nonsmokers aged 53-74 years, unexposed to other sources of tobacco, who received a complete periodontal examination at visit 4. Exposure was reported as average hours per week in close contact with a smoker in the preceding year. We defined severe periodontitis as 5 or more periodontal sites with probing pocket depth of 5 millimeters or more and clinical attachment levels of 3 millimeters or more in those sites. Other outcomes were extent of periodontal probing depths of 4 millimeters or more and extent of clinical attachment levels of 3 millimeters or more. Results. In a binary logistic regression model, adjusted odds of severe periodontitis for those exposed to secondhand smoke 1 to 25 hours per week increased 29% (95% confidence interval=1.0, 1.7); for those exposed to secondhand smoke 26 hours per week, the odds were twice as high (95% confidence interval=1.2, 3.4) as for those who were unexposed. Conclusions. Exposure to secondhand smoke and severe periodontitis among nonsmokers had a dose-dependent relationship. [ABSTRACT FROM AUTHOR]

Abstract: Explanations for the social gradient in health status are informed by the rare exceptions. This cross-sectional observational study examined one such exception, the “Latino paradox” by investigating the presence of a Latino advantage in oral health-related quality of life and the effect of nativity status on this relationship. A nationally representative sample of adults (n =4208) completed the National Health and Nutrition Examination Survey (NHANES) 2003–2004. The impact of oral disorders on oral health-related quality of life was evaluated using the NHANES Oral Health Impact Profile. Exposures of interest were race, ethnicity and nativity status. Covariates included sociodemographic characteristics, smoking status, self-rated health, access to dental care and number of teeth. Unconditional logistic regression models estimated odds of impaired oral health-related quality of life for racial/ethnic and nativity groups compared to the Non-Latino white population. Overall, prevalence of impaired oral health-related quality of life was 15.1%. A protective effect of Latino ethnicity was modified by nativity status, such that Latino immigrants experienced substantially better outcomes than non-Latino whites. However, the effect was limited to first-generation Latinos. U.S. born Latinos did not share the oral health-related quality of life advantage of their foreign-born counterparts. This advantage was not attributable to the healthy migrant phenomenon since immigrants of non-Latino origin did not differ from Non-Latino whites. The excess risk among Non-Hispanic Blacks was rendered non-significant after adjustment for socioeconomic position. A protective effect conferred by Latino nativity is unexpected given relatively disadvantaged socioeconomic position of this group, their language barrier and restrictions to needed dental care. As the Latino advantage in oral health-related quality of life is not explained by healthy immigrant selection, cultural explanations seem more likely than explanations based on characteristics of individuals.

The US National Health and Nutrition Examination Survey (NHANES 2003–2004) evaluated oral health quality of life for the first time using a previously untested subset of seven Oral Health Impact Profile (OHIP) questions, i.e. the NHANES-OHIP. Objectives: (i) To describe the impact of dental conditions on quality of life in the US adult population; (ii) to evaluate construct validity and adequacy of the NHANES-OHIP in NHANES 2003–2004 and a comparable Australian survey. Methods: In the cross-sectional NHANES 2003–2004 survey of a nationally representative sample of US adults ( n = 4907), prevalence was quantified as the proportion of adults who reported experiencing one or more impacts fairly often or very often within the past year. Construct validity was tested by comparing prevalence estimates across categories of sociodemographic, dental health and utilization characteristics known to vary in oral health. In 2002, Australian cross-sectional survey of a nationally representative sample of adults ( n = 2644), adequacy of the NHANES-OHIP questions were tested with reference to a slightly modified version of the OHIP-14 questions. Results: NHANES-OHIP prevalence estimates were markedly similar in the United States (15.3%) and Australia (15.7%). In the US construct, validity was evidenced by higher NHANES-OHIP scores among groups with greater levels of tooth loss, perceived treatment need and problem-oriented visiting and with lack of private dental insurance and low income. In Australia, prevalence for the NHANES-OHIP closely resembled prevalence estimates of the modified OHIP-14. Both varied to a similar degree across levels of tooth loss, perceived treatment need, problem-oriented visiting, and private dental insurance and income, demonstrating adequacy of the NHANES-OHIP as a brief independent instrument. Conclusions: There was acceptable construct validity and adequacy of the NHANES-OHIP questionnaire. In the United States, the impact of oral disease disproportionately affected disadvantaged groups, a finding that supports application of the US Healthy People 2010 major goals of improved quality of life and reduced health disparities.

Objective: To compare perceptions of general health versus oral health within two populations.Methods: Secondary analysis of cross-sectional survey data obtained from representative samples of dentate adults in Australia and the United States. Australian data were collected in the 2002 National Dental Telephone Interview Survey and United States data were from the NHANES, 1988-1994. A stratified analysis compared self-ratings of general and oral health among groups classified by age, socioeconomic status and access to dental care.Results: In Australia, 43.6% rated their dental health 'very good' or 'excellent' whereas 58.6% rated their general health 'very good' or 'excellent'--a deficit of 15.0%. In the US, there was a comparable deficit of 24.2%. The deficit could be explained as a 'generation gap' where oral health ratings of the youngest cohort resembled the general health ratings of middle-aged adults in Australia and retirees in the US. An 'affluence gap' was evident where the oral health ratings of wealthier adults resembled the general health ratings of disadvantaged adults. Among Australians with private dental insurance who had visited a dentist in the past year the oral health deficit was negligible. Similar stratification in the US sample considerably attenuated the deficit.Conclusion: There is a deficit in perceived oral health compared with general health at all stages of adulthood and spanning the socioeconomic spectrum. The deficit was diminished among insured adults who had made a dental visit within the preceding year, suggesting that improved access to dental services may help redress the discrepancy.

Purpose: The association of second hand smoke or environmental tobacco smoke (ETS) and periodontitis in non-smokers has not been confirmed using a biomarker of ETS exposure. To estimate periodontitis prevalence in non-smokers with detectable serum cotinine, and to investigate racial/ethnic and socioeconomic variation in ETS exposure in a representative sample of the U. S. adult population. Determining periodontitis risk indicators occurring with ETS appears to be a salient purpose as this study is the first of its kind to provide a link (a salivary biomarker) between second hand smoke and risk for periodontitis. Methods: Data were collected from the 1999 to 2004 National Health and Nutrition Examination Survey (NHANES). Subjects were 3,137 adults who had smoked fewer than 100 cigarettes and had not used other forms of tobacco. ETS exposure was classified as negligible (cotinine concentrations below sex and race/ethnicity cut-points for smokers), moderate (cotinine 0.5-<1.5 μg/mL) or high (cotinine≥1.5 ng/mL). Periodontitis was classified according to the Centers for Disease Control and Prevention (CDC) and the American Academy of Periodontology (AAP) case defini tion for moderate-severe disease. Survey estimation procedures were used to estimate prevalence and odds ratios (OR) were from multivariable logistic regression models. Results: ETS exposure was observed in 40.5% of subjects and 2.6% had periodontitis. ETS exposure was inversely associated with educational attainment and family income and was higher in non-Hispanic blacks than whites. After adjusting for age, sex and year of survey, adults with high ETS exposure (cotinine≥1.5 ng/mL) had more than twice the odds of periodontitis as people with negligible exposure (OR=2.3, 95% confidence interval=1.3, 4.1). Conclusion: High ETS exposure was a risk indicator for periodontitis in lifetime non-smokers. [ABSTRACT FROM AUTHOR]

Background: The objectives were to assess (a) the association between poor oral health and mild cognitive impairment (MCI) in Hispanic/Latino immigrants and (b) potential modification effects on this association by age at immigration., Methods: Data were from the Hispanic Community Health Study/Study of Latinos and its ancillary study-the Study of Latinos-Investigation of Neurocognitive Aging. MCI, a binary outcome variable, defined by the National Institute on Aging-Alzheimer's Association criteria. The main exposure was significant tooth loss (STL), defined as a loss of 8 or more teeth, and periodontitis, classified using the Centers for Disease Control and Prevention and American Academy of Periodontology case classification. Multiple logistic regression was used to assess the association between STL/periodontitis and MCI and test moderation effects of age at immigration. The analytical sample comprised 5 709 Hispanic/Latino adult immigrants., Results: Hispanic/Latino immigrants with STL (adjusted odds ratio [AOR] = 1.36, 95% confidence interval [CI]: 1.01-1.85) were more likely to have MCI than those with greater tooth retention. Overall, migration to the United States after age 18 was associated with greater odds of MCI than migration at a younger age. A significant interaction effect between STL and age at immigration revealed that the effect of STL on MCI is even higher in those who immigrated to the United States at ages 35-49 years., Conclusions: STL is a significant risk factor for MCI and age at immigration had a modification effect on the association between STL and MCI. Better access to dental care, health education on risk factors of MCI, and promotion of good oral health may mitigate the burden of cognitive impairment in Hispanics/Latinos., (© The Author(s) 2022.

Objective: To evaluate the association between complete denture use and subsequent mortality among edentulous adults., Methods: Data from 1649 edentulous adults who participated in the Third National Health and Nutritional Examination Survey were linked to public-use mortality files for the period up to December 2015. Denture wearing, defined as use of complete dentures in both arches (clinically inspected) all the time or only when awake, was compared to non-wearing, defined as use of dentures occasionally or not at all. The primary outcome was all-cause mortality. Data on 27 covariates, classified as sociodemographic characteristics, behavioral factors, health insurance, laboratory tests and general health status, were used to create propensity scores for weighted and matched analyses., Results: In weighted data, the difference in mortality rate between denture and non-denture wearers was 11.1 (95 %CI: 3.6-18.6) deaths per 1000 person-years and the number needed to treat (NNT) at 10 years was 12. Denture wearers had 15 % lower risk of death (HR: 0.85; 95 % CI: 0.73-0.98) than non-denture wearers. In the matched sample, the mortality rate difference between denture and non-denture wearers was 8.8 (95 %CI: 0.2-17.4) deaths per 1000 person-years and the NNT at 10 years was 11. Risk of death was 21 % lower among denture wearers (HR: 0.79; 95 % CI: 0.68, 0.92) than non-denture wearers., Conclusion: This longitudinal analysis showed that the use of complete dentures was associated with longer survival and lower all-cause mortality risk among American edentulous adults. NNT is interpreted as one death prevented after 10 years for every twelve rehabilitated dentitions with removable complete dentures., Clinical Significance: Edentulous adults wearing complete dentures had longer survival and lower overall mortality risk than non-denture wearers, suggesting that prosthodontic rehabilitation with removable complete dentures might have benefits beyond restoring oral functioning., (Copyright © 2020 Elsevier Ltd.

Aims: To examine the association of social capital with periodontal disease severity., Materials and Methods: We analysed data obtained from 3,994 men and women aged 18-74 years in the Hispanic Community Health Study/Study of Latinos Sociocultural Ancillary Study (HCHS/SOL SCAS). From 2008 to 2011, dentists assessed periodontitis status with a full-mouth periodontal examination. Periodontitis was classified using standardized case definitions. Multivariable logistic regression estimated odds of moderate-severe periodontitis associated with two measures of social capital: structural support (Social Network Index) and functional support (Interpersonal Support Evaluation List)., Results: For US-born participants, for each additional person in their social network, the adjusted odds of moderate-severe periodontitis was reduced 17% (OR = 0.83, 95% CI = 0.71, 0.96). However, no association was found between functional support and periodontal disease severity., Conclusions: Greater structural social support was associated with a lower prevalence of moderate-severe periodontitis in US-born Hispanics/Latinos. These findings suggest that US-born Hispanics/Latinos with less social support represent a vulnerable segment of the population at high-risk group for periodontal disease., (© 2020 John Wiley & Sons A/S.

Objective: To explore health literacy as a marker of voter confusion in order to understand the basis for public opposition to community water fluoridation., Design: A cross-sectional study., Setting: Conducted in three large US cities of San Antonio, Texas (602 voting precincts); Wichita, Kansas (171 voting precincts); and Portland, Oregon (132 voting precincts). Precinct-level voting data were compiled from community water fluoridation referendums conducted in San Antonio in 2002, Wichita in 2012 and Portland in 2013., Participants: Voter turnout expressed as a percentage of registered voters was 38% in San Antonio (n=2 92 811), 47% in Wichita (n=129 199) and 38% in Portland (n=164 301)., Main Outcome Measures: The dependent variable was the percentage of votes in favour of fluoridating drinking water. Precinct-level voting data were mapped to precinct scores of health literacy, and to US Census and American Community Survey characteristics of race/ethnicity, age, income and educational attainment. Multilevel regression with post-stratification predicted the precinct mean health literacy scores, with weights generated from the National Association of Adult Literacy health literacy survey, with item response theory computed scoring for health literacy. Predictive models on voter support of community water fluoridation were compared using robust linear regression to determine how precinct-level characteristics influenced voter support in order to determine whether health literacy explained more variance in voting preference than sociodemographic characteristics., Results: Precinct-level health literacy was positively associated with voter turnout, although sociodemographic characteristics were better predictors of turnout. Approximately 60% of voters opposed community water fluoridation in Wichita and Portland, whereas in San Antonio, a small majority (53%) voted in favour of it. Models suggest that a one SD increase in health literacy scores predicted a 12 percentage point increase support for community water fluoridation., Conclusion: Educational attainment and health literacy are modifiable characteristics associated with voting precincts' support for community water fluoridation., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

Study Objectives: To investigate the association between sleep disordered breathing (SDB) and severe chronic periodontitis., Design: Cross-sectional data analysis from the Hispanic Community Health Study/Study of Latinos., Setting: Community-based setting with probability sampling from four urban US communities., Participants: 12,469 adults aged 18-74 y., Interventions: None., Measurements and Results: Severe chronic periodontitis was defined using the Centers for Disease Control and Prevention/American Academy of Periodontology case classification based on full-mouth periodontal assessments performed by calibrated dentists. SDB was evaluated in standardized home sleep tests, and defined as the number of apnea plus hypopnea events associated with ≥ 3% desaturation, per hour of estimated sleep. SDB was quantified using categories of the apnea-hypopnea index (AHI): 0.0 events (nonapneic); 0.1-4.9 (subclinical); 5.0-14.9 (mild); and ≥ 15 (moderate/severe). Covariates were demographic characteristics and established periodontitis risk factors. C-reactive protein was a potential explanatory variable. Using survey estimation, multivariable binary logistic regression estimated odds ratios (OR) and 95% confidence limits (CL). Following adjustment for confounding, the SDB and periodontitis relationship remained statistically significant, but was attenuated in strength and no longer dose-response. Compared with the nonapneic referent, adjusted odds of severe periodontitis were 40% higher with subclinical SDB (OR = 1.4, 95% CL: 1.0, 1.9), 60% higher with mild SDB (OR = 1.6, 95% CL: 1.1, 2.2) and 50% higher with moderate/severe SDB (OR = 1.5, 95% CL: 1.0, 2.3) demonstrating an independent association between SDB and severe periodontitis., Conclusions: This study identifies a novel association between mild sleep disordered breathing and periodontitis that was most pronounced in young adults., (© 2015 Associated Professional Sleep Societies, LLC.)

Purpose: The aim of the study was to examine acculturation and established risk factors in explaining variation in periodontitis prevalence among Hispanic/Latino subgroups., Methods: Participants were 12,730 dentate adults aged 18-74 years recruited into the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) from four U.S. field centers between 2008 and 2011. A standardized periodontal assessment measured probing pocket depth and gingival recession at six sites per tooth for up to 28 teeth. Periodontitis was defined according to the Centers for Disease Control and Prevention and American Academy of Periodontology case classifications developed for population surveillance. Covariates included acculturation indicators and established periodontitis risk factors. Survey estimation procedures took account of the complex sampling design. Adjusted multivariate binomial regression estimated prevalence ratios and 95% confidence limits (CLs)., Results: Unadjusted prevalence of moderate and severe periodontitis was 38.5% and ranged from 24.7% among Dominicans to 52.1% among Cubans. Adjusted prevalence ratios for subgroups relative to Dominicans were as follows: (1) 1.34 (95% CL, 1.13-1.58) among South Americans; (2) 1.37 (95% CL, 1.17-1.61) among Puerto Ricans; (3) 1.43 (95% CL, 1.25-1.64) among Mexicans; (4) 1.53 (95% CL, 1.32-1.76) among Cubans; and (5) 1.55 (95% CL, 1.35-1.78) among Central Americans., Conclusions: Heterogeneity in prevalence of moderate/severe periodontitis among Hispanic/Latino subpopulations was not explained by acculturation or periodontitis risk factors., (Copyright © 2014 Elsevier Inc.

The course of preclinical pain symptoms sheds light on the etiology and prognosis of chronic pain. We aimed to quantify rates of developing initial and recurrent symptoms of painful temporomandibular disorder (TMD) and to evaluate associations with health behaviors. In the OPPERA prospective cohort study, 2,719 individuals aged 18 to 44years with lifetime absence of TMD when enrolled completed 25,103 quarterly (3-monthly) questionnaires during a median 2.3-year follow-up period. Questionnaires documented TMD symptom episodes, headache, other body pain, health care attendance, and analgesic use, and. Kaplan-Meier methods for clustered data estimated symptom-free survival time. Multivariable models assessed demographic variation in TMD symptom rates and evaluated associations with health care and analgesic use. One-third of the study subjects developed TMD symptoms and for a quarter of symptomatic episodes, pain intensity was severe. Initial TMD symptoms developed at an annual rate of 18.8 episodes per 100 persons. The annual rate more than doubled for first-recurrence and doubled again for second or subsequent recurrence such that, 1year after first recurrence, 71% of study subjects experienced a second recurrence. The overall rate increased with age and was greater in African Americans and lower in Asians relative to those of white race/ethnicity. The probability of TMD symptoms was strongly associated with concurrent episodes of headache and body pain and with past episodes of TMD symptoms. Episodes of TMD symptoms, headache, and body pain were associated with increases of ∼10% in probability of analgesic use and health care attendance. Yet, even when TMD, headache, and body pain occurred concurrently, 27% of study subjects neither attended health care nor used analgesics., (Copyright © 2013 International Association for the Study of Pain.

Unlabelled: Persistent stressors associated with sociodemographic disadvantage exert a physiologic toll, labeled "allostatic load," that contributes to disparities in some health conditions. We investigated the contribution of allostatic load to pain prevalence in U.S. adults. Interviews with 14,184 adults in the 1999-2004 National Health and Nutrition Examination Survey asked about severe headache, pain that lasted >24 hours, and widespread pain. Ten biomarkers of allostatic load were quantified from blood (glycated hemoglobin), serum (C-reactive protein, homocysteine, cholesterol, triglycerides), urine (creatinine, albumin), and physical measurements (body mass index, systolic and diastolic blood pressure). Log-binomial regression models estimated prevalence ratios (PRs) and 95% confidence intervals (95% CIs). Prevalence ranged from 3.4% for widespread pain to 26.9% for pain >24 hours. After adjustment for demographic characteristics, low income was associated with greater prevalence of pain >24 hours (PR = 1.65, 95% CI = 1.49, 1.83), severe headache (PR = 2.05, 95% CI = 1.68, 2.50), and widespread pain (PR = 3.67, 95% CI = 2.56, 5.27). Racial/ethnic minorities had lower prevalence of all 3 pain conditions than non-Hispanic whites. While greater allostatic load was associated with elevated prevalence of pain, allostatic load did not meaningfully attenuate PRs associated with income or race/ethnicity. We conclude that greater pain prevalence among low-income groups is not explained by greater allostatic load., Perspective: In U.S. adults, pain occurs more frequently in lower-income groups, although the relationship is not attributable to their experience of greater allostatic load. While allostatic load contributes to population variation in pain, other etiologic mechanisms contributing to pain are needed to account for income disparities in pain., (Copyright © 2012 American Pain Society.
