OBJECTIVE: Self-reported alcohol consumption in U.S. public health surveys covers only 30%–60% of per capita alcohol sales, based on tax and shipment data. To estimate alcohol-attributable harms using alcohol-attributable fractions, accurate measures of total population consumption and the distribution of this drinking are needed. This study compared methodological approaches of adjusting self-reported survey data on alcohol consumption to better reflect sales and assessed the impact of these adjustments on the distribution of average daily consumption (ADC) levels and the number of alcohol-attributable deaths. METHOD: Prevalence estimates of ADC levels (i.e., low, medium, and high) among U.S. adults who responded to the 2011–2015 Behavioral Risk Factor Surveillance System (BRFSS; N = 2,198,089) were estimated using six methods. BRFSS ADC estimates were adjusted using the National Alcohol Survey, per capita alcohol sales data (from the Alcohol Epidemiologic Data System), or both. Prevalence estimates for the six methods were used to estimate average annual alcohol-attributable deaths, using a population-attributable fraction approach. RESULTS: Self-reported ADC in the BRFSS accounted for 31.3% coverage of per capita alcohol sales without adjustments, 36.1% using indexed-BRFSS data, and 44.3% with National Alcohol Survey adjustments. Per capita sales adjustments decreased low ADC prevalence estimates and increased medium and high ADC prevalence estimates. Estimated alcohol-attributable deaths ranged from approximately 91,200 per year (BRFSS unadjusted; Method 1) to 125,200 per year (100% of per capita sales adjustment; Method 6). CONCLUSIONS: Adjusting ADC to reflect total U.S. alcohol consumption (e.g., adjusting to 73% of per capita sales) has implications for assessing the impact of excessive drinking on health outcomes, including alcohol-attributable death estimates.

Social prioritization in scene viewing, a work by Martinez-Cedillo, Dent & Foulsham (2023).

Random-digit dialing (RDD) telephone surveys are challenged by declining response rates and increasing costs. Many surveys that were traditionally conducted via telephone are seeking cost-effective alternatives, such as address-based sampling (ABS) with self-administered web or mail questionnaires. At a fraction of the cost of both telephone and ABS surveys, opt-in web panels are an attractive alternative. The 2019–2020 National Alcohol Survey (NAS) employed three methods: (1) an RDD telephone survey (traditional NAS method); (2) an ABS push-to-web survey; and (3) an opt-in web panel. The study reported here evaluated differences in the three data-collection methods, which we will refer to as “mode effects,” on alcohol consumption and health topics. To evaluate mode effects, multivariate regression models were developed predicting these characteristics, and the presence of a mode effect on each outcome was determined by the significance of the three-level effect (RDD-telephone, ABS-web, opt-in web panel) in each model. Those results were then used to adjust for mode effects and produce a “telephone-equivalent” estimate for the ABS and panel data sources. The study found that ABS-web and RDD were similar for most estimates but exhibited differences for sensitive questions including getting drunk and experiencing depression. The opt-in web panel exhibited more differences between it and the other two survey modes. One notable example is the reporting of drinking alcohol at least 3–4 times per week, which was 21 percent for RDD-phone, 24 percent for ABS-web, and 34 percent for opt-in web panel. The regression model adjusts for mode effects, improving comparability with past surveys conducted by telephone; however, the models result in higher variance of the estimates. This method of adjusting for mode effects has broad applications to mode and sample transitions throughout the survey research industry.

When free-viewing scenes, participants tend to preferentially fixate social elements (e.g. people). We investigated whether this bias is automatic by testing whether it would be disrupted by increasing the demands of a secondary dual-task: holding a set of (1 or 6) spatial locations in memory, presented either simultaneously or sequentially. Following a retention interval, participants judged whether a test location was present in the to-be-remembered stimuli. During the retention interval participants free-viewed scenes containing a social element (e.g. a person) and a non-social element (object) that served as regions of interest. In order to assess the impact of physical salience, the non-social element was presented in both an unaltered baseline version, and in a version where its salience was artificially increased. The results showed that the preference to look at social elements decreased when the demands of the spatial memory task were increased from 1 to 6 locations, regardless of presentation mode (simultaneous or sequential). This reduction in the social prioritisation effect was accompanied by an increased tendency to fixate on the centre of the screen. The results place important boundary conditions on the social prioritisation effect and suggest clear limits to its automaticity.

Tuff beds (volcanic ash beds and tuffs) have been known in the Miocene Monterey and Modelo Formations since they were initially described nearly 100 yr ago. Yet, these tephra layers have remained largely ignored. The ages and correlation of the Monterey and Modelo Formations are predominantly based on associated biostratigraphy. Here, we combined tephrochronology and biostratigraphy to provide more precise numerical age control for eight sedimentary sequences of the Monterey and Modelo Formations from Monterey County to Orange County in California. We correlated 38 tephra beds in the Monterey and Modelo Formations to 26 different dated tephra layers found mainly in nonmarine sequences in Nevada, Idaho, and New Mexico. We also present geochemical data for an additional 19 tephra layers in the Monterey and Modelo Formations, for which there are no known correlative tephra layers, and geochemical data for another 11 previously uncharacterized tephra layers in other areas of western North America. Correlated tephra layers range in age from 16 to 7 Ma; 31 tephra layers erupted from volcanic centers of the Snake River Plain, northern Nevada to eastern Idaho; 13 other tephra layers erupted from the Southern Nevada volcanic field; and the eruptive source is unknown for 12 other tephra layers. These tephra layers provide new time-stratigraphic markers for the Monterey and Modelo Formations and for other marine and nonmarine sequences in western North America. We identified tephra deposits of four supereruptions as much as 1200 km from the eruptive sources: Rainier Mesa (Southern Nevada volcanic field) and Cougar Point Tuff XI, Cougar Point Tuff XIII, and McMullen Creek (all Snake River Plain).

Objective Hispanic immigrants exhibit more positive outcomes than U.S.-born Hispanics across educational, psychological, and physical health indices, a phenomenon called the immigrant paradox. We examined the immigrant paradox in relation to alcohol use severity among Hispanic young adults while considering both positive (optimism) and negative (depressive symptoms) processes. Method Among 200 immigrant and U.S.-born Hispanic young adults (Mage = 21.30; 49% male) in Arizona and Florida, we tested whether optimism and depressive symptoms statistically mediated the relationship between nativity and alcohol use severity. Specifically, we examined whether Hispanic immigrants reported greater optimism than their U.S.-born counterparts, and whether such optimism was, in turn, associated with less depressive symptoms and thus lower alcohol use severity. Results Indirect effects were significant in hypothesized directions (nativity → optimism → depressive symptoms → alcohol use severity). Conclusions Both positive and negative psychological processes are important to consider when accounting for the immigrant paradox vis-a-vis alcohol use severity among Hispanic young adults.

We report two experiments investigating the effect of working memory (WM) load on selective attention. Experiment 1 was a modified version of Lavie et al. and confirmed that increasing memory load disrupted performance in the classic flanker task. Experiment 2 used the same manipulation of WM load to probe attention during the viewing of complex scenes while also investigating individual differences in attention deficit hyperactivity disorder (ADHD) traits. In the image-viewing task, we measured the degree to which fixations targeted each of two crucial objects: (1) a social object (a person in the scene) and (2) a non-social object of higher or lower physical salience. We compared the extent to which increasing WM load would change the pattern of viewing of the physically salient and socially salient objects. If attending to the social item requires greater default voluntary top-down resources, then the viewing of social objects should show stronger modulation by WM load compared with viewing of physically salient objects. The results showed that the social object was fixated to a greater degree than the other object (regardless of physical salience). Increased salience drew fixations away from the background leading to slightly increased fixations on the non-social object, without changing fixations on the social object. Increased levels of ADHD-like traits were associated with fewer fixations on the social object, but only in the high-salient, low-load condition. Importantly, WM load did not affect the number of fixations on the social object. Such findings suggest rather surprisingly that attending to a social area in complex stimuli is not dependent on the availability of voluntary top-down resources.

INTRODUCTION: During the COVID-19 pandemic, online video platforms became the primary mode of accessing substance use-focused mutual-help group meetings, which may persist after in-person meetings are available again. This study examined the characteristics (demographic, substance use and recovery, and mutual-help group use) of attendees of online recovery support meetings, and associations of online meeting attendance with substance use outcomes, using national data (without ensured representativeness) collected before the pandemic. METHODS: Data were from the Peer Alternatives in Addiction (PAL) Study of attendees of 12-step groups (e.g., Alcoholics Anonymous), Women for Sobriety (WFS), LifeRing Secular Recovery (LifeRing), and SMART Recovery (SMART). The baseline sample, collected in 2015 (pre-pandemic), was 647 adults with lifetime alcohol use disorder who were surveyed online at baseline and 6-month (81%) and 12-month follow-up (83%). RESULTS: At baseline, 62% (n=402) had attended an online mutual-help group meeting in their lifetime, and 36% (n=236) had done so in the past 30 days. Bivariate analyses found that online meeting attendance was more likely among women than men, younger than older participants, and participants with more recent alcohol and drug use, and less abstinence self-efficacy. In addition, online meeting attendance was more likely among respondents who attended two or more different types of mutual-help groups (rather than just one type), and whose primary group was 12-step or WFS rather than LifeRing or SMART. Longitudinal analyses found an interaction between online meeting attendance (yes or no) and time on the outcomes of alcohol and total abstinence such that, compared to those who did not attend online meetings, online meeting attendees were less likely to be abstinent at baseline but were about the same on abstinence at 12 months. However, the interaction effect was attenuated when the model adjusted for mutual-help use characteristics. CONCLUSIONS: The findings inform mutual-help groups, providers, and researchers’ efforts to sustain and expand this resource by suggesting that online meeting attendance may have appeal and be helpful to mutual-help group members who are earlier in their recovery.

We assessed the feasibility and acceptability of collecting a saliva sample for DNA through the mail from a national sample of drinkers and examined whether targeted messaging would increase the response rates of Black/African American and Hispanic/Latino participants. We invited respondents from two prior national population surveys to participate in a brief telephone survey regarding recent alcohol use and to mail in a self-administered saliva sample. Blacks/African Americans, Hispanics/Latinos, and Whites had similar rates of consenting to participate. A higher proportion of respondents with a college education and a family history of alcohol problems consented. The differences in participation between respondents receiving targeted and general messaging were not statistically significant. This study provides preliminary evidence for the feasibility of recruiting diverse participants into a genetic study of alcohol use disorder.

Aims The experiment tested the effects of a web‐push survey research protocol, compared with the standard mailed paper‐and‐pencil protocol, among young adults aged 19–30 years in the ‘Monitoring the Future’ (MTF) longitudinal study. Design, Setting and Participants The US‐based MTF study has measured substance use trends among young adults in panel samples followed biennially, using consistent mailed survey procedures from 1977 to 2017. In 2018, young adult participants in the MTF longitudinal component scheduled to be surveyed at ages 19–30 in 2018 (from high school senior cohorts of 2006–17, n = 14 709) were randomly assigned to receive the standard mail/paper survey procedures or new web‐push procedures. Measurements Primary outcomes were responding to the survey and prevalence estimates for past 30‐day use of alcohol, cigarettes, marijuana and illicit drugs. Findings The web‐push response rate was 39.07% [95% confidence interval (CI) = 37.889, 40.258]; this was significantly better than the standard MTF response rate of 35.12% (95% CI = 33.964, 36.285). After adjusting for covariates, the web‐push condition was associated with a 19% increase in the odds of responding compared with standard MTF (adjusted odds ratio = 1.188; 95% CI = 1.096, 1.287). Substance use prevalence estimates were very similar and differences became negligible when using attrition weights and controlling for socio‐demographic characteristics. Conclusions The web‐push protocol produced a higher response rate than the mailed pencil and paper protocol in the Monitoring the Future panel study, without substantially affecting estimates of substance use once attrition weights and socio‐demographic variables were factored in.

Background Studies show drinking to cope and mental health problems have increased during the COVID-19 pandemic, however, their samples have been limited by convenience sampling or lack of a pre-pandemic measure. We examined the early impact of the COVID-19 pandemic on mental health, drinking to cope and their association using a probability-based sample of the US adult population. Methods Data was drawn from the probability samples of the 2019–2020 National Alcohol Survey (N = 7,233) to examine differences in drinking to cope and symptoms of depression and anxiety. Analyses compared participants who responded to the survey just prior to the widespread onset of the pandemic to those who responded after March 2020, in the total sample and by sex. Results Respondents in the early- vs. pre-COVID-19 period had a 1.48 higher odds (p = 0.03) of higher agreement with drinking to forget one’s worries and problems, with a significant association observed among women only. Respondents with symptoms of depression and anxiety had a 2.94 and 1.56 higher odds, respectively, of higher agreement with drinking to forget one’s worries. We observed significant associations between early- vs. pre-COVID-19 period, depression and anxiety symptoms, and drinking to forget one’s worries among women only; however, moderation by sex in the total sample was not statistically significant. Conclusions We observed higher prevalence of depression and anxiety symptoms and greater drinking to forget worries in the early months of COVID restrictions relative to the period just prior, with some effects more prominent among women. These observations call for sustained monitoring of and support for the mental health of the general population, and of women in particular during the course of the pandemic.

Author(s): Subbaraman, Meenakshi S; Thomas, Sue; Treffers, Ryan; Delucchi, Kevin; Kerr, William C; Martinez, Priscilla; Roberts, Sarah CM | Abstract: BackgroundPolicies regarding alcohol use during pregnancy continue to be enacted and debated in the United States. However, no study to date has examined whether these policies are related to birth outcomes-the outcomes they ultimately aim to improve. Here, we assessed whether state-level policies targeting alcohol use during pregnancy are related to birth outcomes, which has not been done comprehensively before.MethodsThe study involved secondary analyses of birth certificate data from 148,048,208 U.S. singleton births between 1972 and 2013. Exposures were indicators of whether the following 8 policies were in effect during gestation: Mandatory Warning Signs (MWS), Priority Treatment for Pregnant Women, Priority Treatment for Pregnant Women/Women with Children, Reporting Requirements for Data and Treatment Purposes, Prohibitions Against Criminal Prosecution, Civil Commitment, Reporting Requirements for Child Protective Services Purposes, and Child Abuse/Child Neglect. Outcomes were low birthweight (l2,500ng), premature birth (l37nweeks), any prenatal care utilization (PCU), late PCU, inadequate PCU, and normal (≥7) APGAR score. Multivariable fixed-effect logistic regressions controlling for both maternal- and state-level covariates were used for statistical analyses.ResultsOf the 8 policies, 6 were significantly related to worse outcomes and 2 were not significantly related to any outcomes. The policy requiring MWS was related to the most outcomes: specifically, living in a state with MWS was related to 7% higher odds of low birthweight (pnln0.001); 4% higher odds of premature birth (pnln0.004); 18% lower odds of any PCU (pnln0.001); 12% higher odds of late PCU (pnln0.002); and 10% lower odds of a normal APGAR score (pnln0.001) compared to living in a state without MWS.ConclusionsMost policies targeting alcohol use during pregnancy do not have their intended effects and are related to worse birth outcomes and less PCU.

OBJECTIVE: There is a lack of epidemiological information on drug use in the U.S.–Mexico border. MATERIALS AND METHODS: Data are from the U.S.–Mexico Study on Alcohol and Related Conditions (UMSARC, 2011-2013), a survey of 4,796 randomly selected Mexican and Mexican origin individuals on both sides of the border. RESULTS: Higher rates of any past-year drug use and symptoms of drug use disorders were found only in the border city of Laredo, when compared to the non-border city of San Antonio; Nuevo Laredo and Reynosa/Matamoros showed higher rates of drug use than the non-border city of Monterrey. Much higher rates (OR's in the range of 4-11) were found in the U.S. cities when compared to their across-the-border Mexican counterparts. CONCLUSIONS: Drug use is high on the border for the selected Mexican cities. Misuse of prescription drugs is nevertheless a concern in the south Texas border cities in our study.

Background and Objectives There is a paucity of genetics research examining alcohol use among Latinos. The purpose of this study is to examine Latino perceptions of participation in alcohol studies that collect biological samples, an important precursor to increasing their participation in genetics research. Methods A synthesis of the literature addressing participation of racial/ethnic minorities in alcohol genetics research was undertaken. We developed a framework of themes related to barriers and facilitators for participation, which we then used to analyze two focus groups held with 18 Latino participants. Results From the literature review, we identified nine themes related to facilitators of and barriers to participation. They are, on continua: curiosity to disinterest; trust to mistrust; understanding to confusion; safety to danger; inclusion to exclusion; sense of connection to disconnection; hope to despair; ease to hassle; and benefit to cost. Another theme emerged from the focus groups: previous experience to no previous experience with health research. Conclusions Applying the themes from the literature review to Latino perspectives on providing biological samples for alcohol research helps expand their definition and applicability. Consideration of these themes when designing recruitment/retention materials and strategies may encourage Latino participation in alcohol genetics research. Scientific Significance An understanding of these themes and their significance for Latinos is offered in the form of “guiding questions” for researchers to consider as we strive for more inclusive research. Focus group participants were Mexican American; future research should further explore perspectives of this heterogeneous demographic group by studying other Latino subgroups.

A multi-modular donor-acceptor triad composed of zinc porphyrin, BF2-chelated dipyrromethene (BODIPY), and C60 was newly synthesized, with the BODIPY entity at the central position. Using absorbance and emission spectral, electrochemical redox, and computational optimization results, energy level diagrams for the ZnP-BODIPY dyad and ZnP-BODIPY-C60 triad were constructed to envision the different photochemical events upon selective excitation of the BODIPY and ZnP entities. By transient absorption spectral studies covering a wide femtosecond-to-millisecond time scale, evidence for the different photochemical events and their kinetic information was secured. Efficient singlet-singlet energy transfer from 1BODIPY* to ZnP with a rate constant kENT = 1.7 × 1010 s-1 in toluene was observed in the case of the ZnP-BODIPY dyad. Interestingly, in the case of the ZnP-BODIPY-C60 triad, the selective excitation of ZnP resulted in electron transfer leading to the formation of the ZnP˙+-BODIPY-C60˙- charge-separated state. Owing to the distal separation of the radical cation and radical anion species (edge-to-edge distance of 18.7 A), the radical ion-pair persisted for microseconds. By contrast, the selective excitation of BODIPY resulted in an ultrafast energy transfer to yield ZnP-BODIPY-1C60* as the major product. The 1C60* populated the low-lying 3C60* via intersystem crossing prior to returning to the ground state. The present study successfully demonstrates the importance of supramolecular geometry and selection of excitation wavelength in regulating the different photoprocesses.

Background Valid measurement of alcohol use can be difficult in surveys, which are subject to biases like underreporting and differential nonresponse. Still, monitoring trends, policy impacts, disparities, and related issues all require valid individual- and state-level drinking data collected over time. Here, we propose a double-adjustment approach for improving the validity of the Behavioral Risk Factor Surveillance System (BRFSS) alcohol measures. Methods Validity analyses of the 1999 to 2016 BRFSS, a general population survey of U.S. adults. Measures are aggregated to state level for N = 918 observations, single-adjusted for BRFSS methodologic changes, and double-adjusted by per capita consumption. Fixed-effects models: (i) assess predictive validity using adjusted BRFSS drink volume to predict mortality outcomes and (ii) assess outcome validity using state-level alcohol taxes to predict adjusted BRFSS volume. Results Neither the raw nor the single-adjusted BRFSS drinking measures were related to mortality in the expected direction, while double-adjusted BRFSS volume and 5+ days were significantly positively related to mortality, as expected. Spirits and beer taxes were not related to single-adjusted BRFSS drinking in the expected direction. However, spirits and beer taxes were both significantly related to double-adjusted BRFSS volume in the expected directions. Conclusions Future studies should consider using the double-adjusted BRFSS measures to ensure the validity of drinking survey data in analyses where variation over time is considered.

OBJECTIVES: The misuse of prescription drugs in the U.S. is an alarming public health crisis. Prior research at the U.S.-Mexico border has found high rates of prescription drug misuse, but with rates varying significantly across border communities. We aimed to examine a model of permissive climate measures and stress exposures as potential mediators of community differences in prescription drug misuse at the U.S.-Mexico border. DESIGN: We analyzed data from the U.S.-Mexico Study of Alcohol and Related Conditions (UMSARC). Household, in-person interviews were conducted with Mexican-origin residents of the Texas border cities Laredo (n=751) and Brownsville/McAllen (n=814). Interviews assessed past-year misuse of any and pain-reliever prescription drugs. Drug availability, neighborhood safety, exposure to violence/crime, and social support were examined as potential mediators. Analyses were stratified by gender and employed regressions and mediation analysis with Mplus. RESULTS: The past-year prevalence of any prescription drug misuse in Laredo was 26.3% among women and 24.4% among men, and in Brownsville/McAllen was 12.4% among men, and 6.7% among women. Mediation analysis revealed site effects via some of the hypothesized risk factors for men, but not for women. Specifically, for men, site effects on any and pain reliever prescription drug misuse were partially mediated via high drug availability and low family support. CONCLUSIONS: Past-year prescription drug misuse was over 3 times the 2015 national prevalence among both men and women in Laredo and calls for immediate attention. Findings regarding the model suggest drug availability and social support may be relevant to understanding community differences in prescription drug misuse among men living at the border, and that additional factors should be investigated to understand misuse among women living at the border.

BACKGROUND: Even given equivalent drinking patterns, Black and Latino men experience substantially more dependence symptoms and other consequences than White men, particularly at low/no heavy drinking. No known studies have identified factors driving these disparities. The current study examines this question. METHODS: The 2005 and 2010 National Alcohol Surveys were pooled. Surveys are nationally representative, telephone interviews of the U.S. including Black and Latino oversamples; male drinkers were analyzed (N=4182). Preliminary analyses included negative binomial regressions of dependence symptom and consequence counts testing whether effects for race/ethnicity were diminished when entering potential explanatory factors individually. Additional analyses re-examined effects for race/ethnicity when using propensity score weighting to weight Blacks to Whites, and Latinos to Whites, first on heavy drinking alone, and then on heavy drinking and all explanatory factors supported by preliminary analyses. RESULTS: Preliminary regressions suggested roles for lower individual SES, greater prejudice and unfair treatment, and younger age in the elevated risk of alcohol problems among Black and Latino (vs. White) men at low heavy drinking levels; additional support emerged for single (vs. married) status among Blacks and neighborhood disadvantage among Latinos. When Blacks and Latinos were weighted to Whites on the above variables, effects for race/ethnicity on dependence counts were reduced to nonsignificance, while racial/ethnic disparities in consequence counts were attenuated (by >43% overall). CONCLUSIONS: Heavy drinking may be especially risky for those who are poor, exposed to prejudice and unfair treatment, young, and unmarried, and these factors may contribute to explaining racial/ethnic disparities in alcohol problems.Copyright © 2016 Elsevier Ireland Ltd.

BACKGROUND AND AIMS: Including a low-intensity blood collection method in population-based alcohol studies would advance our ability to study biological mechanisms related to alcohol. However, the likelihood of participation in such a blood collection method remains understudied. This study’s primary aims were to (1) estimate the return rate of mail-in, self-administered dried blood spot (saDBS) samples in national surveys and (2) test correlates of returning a sample. DESIGN: Re-contact of all eligible participants from two telephone, population-based alcohol surveys followed by chi-square tests and multivariate logistic regression analysis. SETTING: Non-institutionalized U.S. population in all 50 states and Washington, D.C. PARTICIPANTS: Adults aged 18+ who reported drinking at least one alcoholic beverage in the past 12 months (assessed 2017–2018). Contact was made with 680 eligible participants, and 257 consented. MEASUREMENTS: The return rate of saDBS samples was defined as the proportion of returned samples among those who were eligible and contacted. Key correlates examined were gender, age, race/ethnicity, and education. FINDINGS: Among the 680 eligible people contacted, 179 (26.3%) returned a saDBS sample. Blacks (OR = 0.60, 95% CI = 0.37–0.98), Latinos (OR = 0.41, 95% CI = 0.23–0.71) and those with a high school education or less (OR = 0.49, 95% CI = 0.31–0.79) were less likely to return a saDBS sample. CONCLUSIONS: The likelihood of participating in mail-in, self-administered dried blood spot (saDBS) sampling among drinkers in the U.S. general population appears low, and Blacks, Latinos, and people with lower levels of education appear less likely to provide a saDBS sample compared with Whites and people with higher levels of education.

Author(s): Martinez, Priscilla; Kerr, William C; Subbaraman, Meenakshi S; Roberts, Sarah CM | Abstract: BACKGROUND:Recent increases in alcohol-related morbidity and mortality have not occurred alongside notable increases in per capita alcohol consumption (PCC). This discrepancy may be partially due to U.S. PCC estimates not including annual estimates of the percentage of alcohol by volume (%ABV) of beer, wine, and spirits, but rather relying on time-invariant %ABV values. METHODS:Building on a prior study covering 1950 to 2002, estimates of the annual mean %ABV of beer, wine, and spirits sold in the United States were calculated using the %ABV of major brands and sales of each beverage type for each state and nationally for the period 2003 to 2016. We applied these estimates to the calculation of annual beverage-specific and total PCC, and made descriptive comparisons between our PCC estimates and those estimates using invariant %ABV values. RESULTS:For all beverage types, our mean %ABV estimates increased nationally and for all but 5 states. The PCC estimates from wine and spirits utilizing variable %ABV values were lower than estimates using invariant %ABV, and consumption from beer was higher. Our total PCC estimates were also lower than %ABV-invariant estimates; however, the percent change for %ABV-invariant estimates was 5.8% compared to a 7.9% change in our %ABV-variant estimates over the 2003 to 2016 period. CONCLUSIONS:Given the application of PCC estimates to understand changes in alcohol-related morbidity and mortality, the inclusion of annual estimates of the %ABV of alcoholic beverages sold in the United States is necessary to ensure the precision of PCC measures such that the conclusions drawn from these applications are accurate and valid.

Research suggests striking disparities in alcohol use, problems, and treatment across racial/ethnic groups in the United States. However, research on alcohol-related disparities affecting racial/ethnic minorities remains in its developmental stages. The current article aims to support future research in this growing field by highlighting some of the most important findings, questions, and approaches, focusing on psychosocial research.This article advances seven research needs (i.e., questions and topics meriting attention) that we believe are of crucial importance to the field. We draw on the existing literature to illuminate under-explored areas that are highly relevant to health intervention and that complement the field's existing focus.Identified research needs include research that (a) better describes disparities in alcohol-related health conditions and their drivers, (b) identifies appropriate screening and brief intervention methods for racial/ethnic minorities, (c) investigates disparities in access to and use of alcohol treatment and support services, (d) examines the comparative efficacy of existing alcohol interventions and develops tailored interventions, (e) explores the impacts of specific alcohol policies across and within racial/ethnic groups, and (f) describes the full spectrum of alcohol-related harms and how and why these may vary across racial/ethnic groups. We also call for (g) continuing research to monitor disparities over time.This article points to specific strategies for describing, explaining, intervening on, and monitoring some of the most substantial alcohol-related disparities. Conclusions outline methods and processes that may be advantageous in addressing these priorities, including the use of longitudinal designs; consideration of life course changes; attention to nontraditional intervention settings; and inclusion of disadvantaged populations in all aspects of research.

Objectives: The study compared the proportion of older adults identified as drinking hazardously based on the Alcohol Use Disorders Identification Test–Consumption (AUDIT-C) with the older adult-specific Comorbidity Alcohol Risk Evaluation Tool (CARET) and investigated whether sociodemographics, comorbidities, health, medication use, and alcohol-related risk behaviors explained discrepancies between the screens in classification of hazardousness. Method: The AUDIT-C and the CARET were administered to 3,673 adults aged 55 to 89 years. Classification agreement between the screens was evaluated using Cohen’s kappa. Hazardous drinking groups were compared using logistic regression. Results: Analysis indicated moderate agreement between the screens. Drinkers classified as “hazardous on the CARET only” consumed less alcohol, but were more likely to drink-drive. Introducing a drink-driving criterion into the calculation of hazardousness on the AUDIT-C substantially decreased the classification discrepancy between the measures. Discussion: Standard screening can be improved by investigating comorbidities, medication use, and alcohol-related risk behaviors in those initially identified as nonhazardous drinkers.

Background Psychological distress is common among people with a substance abuse disorder in treatment. Identifying correlates of psychological distress may serve as points of intervention to improve substance abuse treatment outcomes. Immune function measured as cytokine levels have been associated with psychological distress, but this association remains unexplored among people with a substance abuse disorder in treatment. This study aimed to examine whether cytokine levels in patients treated for a substance use disorder were related to depression, anxiety, and overall psychological distress, and to observe these associations separately among people with a past year alcohol use disorder and those with a past year drug use disorder. Methods We collected cross-sectional data from 80 inpatients at five alcohol and substance abuse treatment centers in Norway. We determined alcohol and drug diagnoses, and assessed symptoms of depression, anxiety, and overall psychological distress. We tested blood samples for IL-1, IL-6, TNF-α, INF-γ, and IL-10. We used multivariate linear regressions to examine the associations between cytokine levels and psychological distress measures. Results All cytokines were significantly and positively associated with depression score. INF-γ was significantly and negatively associated with anxiety, and IL-6 was significantly and positively associated psychological distress. Among people with only an alcohol use disorder, IL-6 was positively associated with depression and psychological distress scores, and IL-10 was negatively associated with anxiety score. Among people with only a drug use disorder, TNF-α was positively associated with depression score. Conclusion The relationship between immune function and psychological distress is robust in the context of substance abuse, and further research is warranted.

The objective of this study was to describe prevalence of alcohol use and risky drinking across socio-demographic factors in South Sudan, and to determine the association between risky drinking, traumatic events and mental distress. Methods This is a randomized, population based, cross-sectional study from the north-western part of South Sudan with nearly 500 participants. We used the Alcohol Use Disorders Identification Test (AUDIT) as main outcome variable, the General Health Questionnaire (GHQ-28) for mental distress and five questions to assess traumatic events. Results The mean AUDIT score was 2.7 (SD 0.3) with 14,2 % in the high risk problem drinking category. Being male, lack of a regular income and psychological distress were significantly associated with higher AUDIT score. Traumatic events, however, was not associated with higher score on AUDIT. Conclusion Despite decades of civil war and great poverty the alcohol use in this population was at the same level as other countries in Southern Africa. Traumatic events were not related to risk of problem drinking.

Background Alcohol use is a well-known risk factor for injury. However, information is needed about alcohol drinking patterns and the risk of injury among older adults in low- and middle-income countries as this population grows. We aimed to examine the influence of drinking patterns on the burden of injury and investigate factors associated with different types of injury in older populations in six emerging economies. Methods Data from more than 37,0 adults aged 50 years and older were included from the Study on Global AGEing and Adult Health (SAGE) Wave 1 conducted in six emerging economies, namely, China, Ghana, India, Mexico, Russia, and South Africa. We investigated past-year reported injuries from falls, traffic accidents, and being hit or stabbed. Alcohol drinking patterns were measured as lifetime abstinence, ever but not past- week use, and gender-specific past-week low-risk and high-risk use. We stratified by gender and used logistic regression models to observe the association between alcohol drinking pattern and risk of injury by controlling for other factors. Results During the year prior to interview, 627 (2.2%) subjects reported bodily injury resulting from a car accident, 1,156 (4.2%) from a fall, and 339 (.9%) from being hit or stabbed during the past year. For women, only being a high-risk drinker increased the risk of being hit or stabbed, whereas for men, all levels of drinking were associated with an increased risk of being hit or stabbed. We observed a higher risk of being hit or stabbed from past-week high-risk drinking among women (odds ratio [OR] = 6.09, P < 0.01) than among men (OR = 3.57, P < 0.01). We observed no association between alcohol drinking pattern and injury due to car accidents for either women or men. Conclusions The risk of experiencing injury due to violence increased with level of alcohol exposure of the victim. The increase in alcohol use in emerging economies calls for further study into the consequences of alcohol use and for public health initiatives to reduce the risk of violence in older adult populations, with special attention to the experience of older adult women.

Objective: The growth of the older adult population in Africa demands more knowledge about their chronic health problems, such as depression. The aim of this paper is to estimate depression prevalence and identify correlates of depression among older adults in Ghana and South Africa. Method: The WHO Study on global AGEing and adult health (SAGE study) was conducted in Ghana and South Africa from 2007 to 2009 by the World Health Organization, using a standardized questionnaire among an adult population. Our analyses included 4289 adults aged 50 and above in Ghana and 3668 in South Africa. Depression was measured using self-reported symptoms over the last 12 months according to ICD-10 criteria. Results: The prevalence of mild depression was 6.7% and 2.7% in Ghana and South Africa, respectively (p

Background Activation of the kynurenine pathway of tryptophan metabolism results in increased production of potentially depressogenic tryptophan catabolites and a reduction in tryptophan availability for serotonin synthesis. As alcohol consumption affects tryptophan metabolism and disposition, we determined serum levels of tryptophan, kynurenine, and an index of tryptophan degradation (kynurenine/tryptophan ratio) in patients with alcohol-use disorder (AUD) and compared their levels considering abstinence duration, AUD severity, and comorbid depression. Methods The study sample included 169 AUD inpatients from 8 alcohol treatment facilities in Kathmandu, Nepal. The Composite International Diagnostic Interview was administered to generate the AUD diagnosis. The Alcohol Use Disorder Identification Test (AUDIT) captured AUD severity and patterns of alcohol use. The Hopkins Symptom Checklist-25 was used to reveal current depressive symptoms. Serum kynurenine and tryptophan levels were determined by high-performance liquid chromatography, and tryptophan degradation was measured by KT ratio (kynurenine/tryptophan × 10(3)). Results Patients with above average AUDIT scores had higher mean serum levels of kynurenine (2.1 μM ± 0.7 vs. 1.8 μM ± 0.6, p = 0.006) and KT ratios (48.6 ± 17.6 vs. 40.4 ± 14.3, p = 0.002) than those with below average scores. Patients with current depressive symptoms had higher mean tryptophan concentrations (49.9 μM ± 13 vs. 45.7 μM ± 14.1, p = 0.047) and lower KT ratios (41.4 ± 14 vs. 47.5 ± 17.6, p = 0.028) compared to patients whose reported depressive symptoms were below the standard cutoff. Higher tryptophan levels and lower KT ratios in the depressed group were specific to patients with longer abstinence and higher AUD severity. Conclusions Depression-related deregulation in tryptophan metabolism was found to depend on length of abstinence and on AUD severity. Together, results suggest that in AUD populations, peripheral tryptophan metabolism is subject to interactions between AUD severity and depressive symptoms.

Background Few nationally representative studies have examined racial/ethnic disparities in alcohol services utilization. Further, little is known about whether racial/ethnic disparities generalize across genders, and what factors account for these disparities. Thus, we aimed to describe the combined impact of race/ethnicity and gender on alcohol services utilization, and to explore the roles for social influence factors in explaining racial/ethnic and gender disparities. Methods Data were pooled across the 2000, 2005, and 2010 National Alcohol Surveys. Outcomes included lifetime utilization of any services, specialty alcohol treatment, and Alcoholics Anonymous. Social influence factors were assessed as lifetime social pressures (i.e., pressures from a partner, friends, and/or family), legal consequences, and work-related consequences. Core analyses included only those with a lifetime alcohol use disorder (AUD). Results Analyses revealed a pattern of lower services utilization among Latinos and Blacks (vs. Whites) and women (vs. men); further, race-by-gender interactions revealed that Black–White differences were limited to women, and provided some evidence of stronger Latino–White disparities among women (vs. men). Illustrating these patterns, among women, only 2.5% of Latinas and 3.4% of Blacks with a lifetime AUD accessed specialty treatment, versus 6.7% of Whites; among men, corresponding figures were 6.8% for Latinos, 12.2% for Blacks, and 10.1% for Whites. Racial/ethnic differences were typically robust (or stronger) when controlling for demographics and AUD severity. Evidence did not support a role for measured social influence factors in racial/ethnic disparities, but did suggest that these factors contribute to gender disparities, particularly among Whites and Blacks. Conclusions Findings for substantial Latino–White and Black–White disparities, especially among women, highlight the need for continuing research on explanatory factors and the development of appropriate interventions. Meanwhile, our evidence for persistent gender disparities and for social influence factors as drivers of these disparities tentatively suggests a need for intensified outreach to female heavy drinkers.

Background: Major depressive disorder is highly prevalent among HIV-infected persons, and depression symptom severity improves during the course of HIV antiretroviral therapy (ART). The potential biologic pathways explaining these phenomena remain unclear. We investigated the extent to which ART-mediated suppression of the kynurenine pathway of tryptophan catabolism (via indoleamine 2,3-dioxygenase-1 and potentially other sources) may correlate with improvements in depression symptom severity in this setting. Method: We used the first year of data from the Uganda AIDS Rural Treatment Outcomes Study, a prospective cohort of 504 HIV-infected individuals initiating their first ART regimen in rural Uganda. We fitted random-effects regression models to estimate the associations between plasma tryptophan, plasma kynurenine, dietary diversity, and self-reported depression symptom severity. Results: Greater depressive symptoms were associated with both lower plasma tryptophan and higher plasma kynurenine/tryptophan (KT) ratio over 12-month follow-up. In multivariable-adjusted models, declines in KT ratio and increases in plasma tryptophan levels partially explained ART-mediated improvements in depressive symptom severity. The association between KT ratio and depression symptom severity was stronger among persons with protein-deficient diets than among those with protein-rich diets. Conclusions: Indoleamine 2,3-dioxygenase-1-mediated tryptophan catabolism may contribute to depression symptom severity among HIV-infected individuals, particularly among those with poor dietary protein intake. ART-mediated improvements in depressive symptom severity may also be at least partially mediated by immunologic mechanisms. Interventions to reduce immune activation, and dietary protein supplementation, may be promising strategies to further reduce depression in this setting.

Aims - As major depression (MD) is often comorbid with alcohol‐use disorders (AUD) and alcohol itself modulates the immune system, we examined serum levels of interleukin (IL)‐6, IL‐10, tumor necrosis factor (TNF), and interferon (IFN)‐γ in AUD patients with and without MD. Putative interactions between alcohol variables and MD on cytokine levels were also assessed. Methods - A consecutive sample of inpatients with AUD (N = 176) from eight alcohol treatment centers in Kathmandu, Nepal, was assessed for alcohol use and depression by administering fully structured psychiatric interviews. Serum cytokine levels were determined using multiplex technology. Results - Alcohol‐use disorders patients with a positive history of MD had higher levels of the inflammatory cytokines IL‐6 (P = 0.019), TNF (P = 0.020), and IFN‐γ (P = 0.001), but not of IL‐10 (P = 0.853). AUD patients with MD had higher concentrations of cytokines compared with those without, regardless of the severity of the alcohol problem, but the difference was greater among those drinking in lower frequency and intensity. Conclusion - These findings provide evidence for altered functioning of the immune system in AUD patients with comorbid MD. However, frequent and intense drinking may attenuate the difference in the cytokine profiles between AUD patients with and without MD.

Background The literature from developed countries suggests a relationship between alcohol use and quality of life and social engagement, where harmful drinkers have lower quality of life and less social engagement. Despite the high rates of harmful alcohol use in South Africa, little is known about the association between drinking pattern and quality of life and social engagement in this context. We aimed to determine if quality of life and social engagement varied across different drinking patterns among older South African adults, contributed to drinking pattern when controlling for socio-demographic factors, and varied differentially between genders. Methods This is a secondary analysis of data from the Survey on Global Ageing and Adult Health (SAGE). Alcohol use was measured as self-reports of use over the previous seven days, and we constructed gender-specific alcohol variables. The WHO Quality of Life-scale was used to measure quality of life, and social engagement was measured by frequency of participation in social activities. We used ANOVA to observe differences in quality of life and social engagement scores across drinking patterns, and regression models were used to identify factors independently associated with drinking pattern. Results There were 2572 (84.4%) lifetime abstainers, and 475 (15.6%) persons who had a drink in the last 7 days. In bivariate analysis, quality of life was lowest among at risk drinking men compared to abstainers (OR = 0.21, p = 0.02), although this association was not significant in adjusted analysis. Social engagement did not vary statistically significantly across the drinking patterns in the total sample or within gender. Conclusions Quality of life and social engagement were not independently associated with drinking pattern among older adults in South Africa in this sample. In order to better understand their alcohol use, further exploratory research is warranted to identify other potentially relevant subjective factors of alcohol use among older adults in South Africa.
