Socioeconomic position indicators and risk of alcohol-related medical conditions: A national cohort study from Sweden

BACKGROUND

Alcohol consumption contributes to excess morbidity and mortality in part through the development of alcohol-related medical conditions (AMCs, including alcoholic cardiomyopathy, hepatitis, cirrhosis, etc.). The current study aimed to clarify the extent to which risk for these outcomes differs as a function of socioeconomic position (SEP), as discrepancies could lead to exacerbated health disparities.

METHODS AND FINDINGS

We used longitudinal Swedish national registries to estimate the individual and joint associations between 2 SEP indicators, educational attainment and income level, and risk of AMC based on International Classification of Diseases codes, while controlling for other sociodemographic covariates and psychiatric illness. We conducted Cox proportional hazards models in sex-stratified analyses (N = 1,162,679 females and N = 1,196,659 males), beginning observation at age 40 with follow-up through December 2018, death, or emigration. By the end of follow-up, 4,253 (0.37%) females and 11,183 (0.93%) males had received an AMC registration, corresponding to overall AMC incidence rates among females and males of 2.01 and 5.20, respectively. In sex-stratified models adjusted for birth year, marital status, region of origin, internalizing and externalizing disorder registrations, and alcohol use disorder (AUD) registration, lower educational attainment was associated with higher risk of AMC in both females (hazard ratios [HRs] = 1.40 to 2.46 for low- and mid-level educational attainment across 0 to 15 years of observation) and males (HRs = 1.13 to 1.48). Likewise, risk of AMC was increased for those with lower income levels (females: HRs = 1.10 to 5.86; males: HRs = 1.07 to 6.41). In secondary analyses, we further adjusted for aggregate familial risk of AUD by including family genetic risk scores for AUD (FGRSAUD), estimated using medical, pharmacy, and criminal registries in extended families, as covariates. While FGRSAUD were associated with risk of AMC in adjusted models (HR = 1.17 for females and HR = 1.21 for males), estimates for education and income level remained largely unchanged. Furthermore, FGRSAUD interacted with income level, but not education level, such that those at higher familial liability to AUD were more susceptible to the adverse effect of low income. Limitations of these analyses include the possibility of false negatives for psychiatric illness registrations, changes in income after age 40 that were not accounted for due to modeling restrictions, restriction to residents of a high-income country, and the inability to account for individual-level alcohol consumption using registry data.

CONCLUSIONS

Using comprehensive national registry data, these analyses demonstrate that individuals with lower levels of education and/or income are at higher risk of developing AMC. These associations persist even when accounting for a range of sociodemographic, psychiatric, and familial risk factors. Differences in risk could contribute to further health disparities, potentially warranting increased screening and prevention efforts in clinical and public health settings.

Adverse Childhood Experiences and Tobacco Use among Latinx Parents in the USA

The current study aimed to understand the effects of adverse childhood experiences (ACEs) and cultural factors on Latinx parents' tobacco use. Tobacco use is the leading cause of death among Latinx individuals in the USA, and parental use has long-term secondary harm for children. Thus, it is important to examine cultural protective factors that could prevent Latinx parents and children from the negative health effects of tobacco use. Data came from 2813 18- to 50-year-old Latinx respondents who participated in the Wave 3 of the National Epidemiological Survey on Alcohol and Related Conditions. They reported having children living in their household and had complete data for the variables of interest. In this sample (mean age = 33.5 years, 53.7% female), 16.4% (95%CI = 14.7%, 18.4%) and 7.4% (95%CI = 6.4%, 8.6%) were current and former smokers, respectively. The multivariate multinomial logistic regression analysis showed that experiencing more ACEs categories was associated with increased likelihood of current and former tobacco use compared to never use. Past year discrimination experiences and being US born (2nd and 3rd-generation parents) also increased the likelihood of current use. Differences in risk of current and former tobacco use were found based on respondents' country of origin, with protection against tobacco use found for most countries compared to being from Puerto Rico. Stronger ethnic-racial identity was not protective against tobacco use. Findings show the importance of considering ACEs and cultural factors when designing and implementing tobacco cessation programs for Latinx parents and increasing awareness of the impact of parents' tobacco use on their children.

Triangulation of evidence on immigration and rates of alcohol use disorder in Sweden: Evidence of acculturation effects

BACKGROUND

This study aimed to determine the robustness of the impact of immigration on risk for alcohol use disorder (AUD) using different measures, designs, and immigrant regional cohorts.

METHODS

The analytic sample included all individuals born between 1950 and 1990 and registered in Sweden from 1973 to 2017. Using Cox regression models, we examined the risk for AUD from Swedish nationwide registries in immigrants to Sweden from seven geographical regions: Africa, Asia and Oceania, Eastern Europe, Finland, Latin America and the Caribbean, Middle East/North Africa, and Western countries. We assessed greater exposure to Swedish culture, which we interpreted as increasing acculturation, by (i) comparing first-generation immigrants and their children with no and one native Swedish parent and (ii) examining age at immigration. The baseline comparison group was the native Swedish population. We also examined AUD risk in first-generation sibling pairs discordant for their age at immigration.

RESULTS

In nearly all immigrant cohorts in Sweden, increasing degrees of acculturation, as assessed by both our variables, were associated with rates of AUD that approached those of the Swedish population. These findings occurred in both men and women and both regional cohorts whose first-generation immigrants had lower and higher levels of AUD than native-born Swedes. For most cohorts, the rates of change with acculturation were greater in women than in men. In sibling pairs from most regions, the sibling who was younger at immigration had a higher rate of AUD.

CONCLUSIONS

An examination of both sexes and two different proxies for acculturation provides consistent support for socio-cultural influences on AUD risk. Our co-sibling analyses suggest that a meaningful proportion of this effect is likely to be causal in nature.

Cardiorespiratory Fitness and Depression Symptoms among Adults During the COVID-19 Pandemic: Cooper Center Longitudinal Study

This study examined the relation between cardiorespiratory fitness (fitness) and depression symptoms prior to and during COVID-19 among adults seeking preventive medical care. Participants consisted of 967 patients attending the Cooper Clinic (Dallas, TX) pre-pandemic (March 2018-December 2019) and during the pandemic (March-December 2020). The outcome, depression symptoms, was based on the Center for Epidemiological Studies-Depression (CES-D). Maximal metabolic equivalents task (MET) levels for fitness were determined from the final treadmill speed and grade. Multiple linear regression models were computed by sex. Analysis revealed that mean fitness decreased from 11.4 METs (SD=2.1) prior to the pandemic to 10.9 METs (SD=2.3) during the pandemic (p-value<0.001). The mean CES-D score increased from 2.8 (SD= 3.1) before to pandemic to 3.1 (SD=3.2) during the pandemic (p-value=0.003). Results from multiple linear regression indicate that increased fitness was associated with a statistically significant decrease in depression scores in men (-0.17 per MET; 95%CI -0.33, -0.02) but not women. This modest decrease may have been tempered by high fitness levels and low depression scores at baseline in this well-educated sample.

Effects of family history of alcohol problems on alcohol consumption: Stronger for medically underserved men

Family history (FH), informed by genetics and family environment, can be used by practitioners for risk prediction. This study compares the associations of FH with alcohol outcomes for medically underserved (MUS) men and women with the associations for non-underserved individuals to assess the utility of FH as a screening tool for this high-priority group. Data were from 29,993 adult lifetime drinkers in the Wave 1 (2001-2002) and Wave 2 (2004-2005) National Epidemiologic Survey on Alcohol and Related Conditions. All variables except FH were measured at Wave 2. Dependent variables were 12-month alcohol consumption and alcohol use disorder (AUD). FH scores (FH-SCORE) measured the proportion of first- and second-degree biological relatives with alcohol problems. MUS status was defined by household income at or below 100% of the federal poverty line and participants reporting no usual source of health care. Multivariate linear and logistic regression models tested main and interaction effects. Models showed a significant interaction of FH-SCORE with MUS status (p < .01), with a stronger effect of FH on alcohol consumption for the MUS group. This moderating effect was weaker for women than for men (FH-SCORE x MUS x Sex three-way interaction: p < .01). AUD models showed a significant positive association with FH-SCORE (p < .001) but no association with MUS status and no significant interaction effects. In this sample of lifetime drinkers, FH was associated with higher alcohol consumption, especially for MUS men. These results encourage additional validation of FH scores to prioritize MUS adults at high risk for alcohol problems to receive preventive interventions.

Divergent changes: abstinence and higher-frequency substance use increase among racial/ethnic minority young adults during the COVID-19 global pandemic

BACKGROUND

Identifying factors influencing substance use among racial/ethnic minorities (REM) is important given the disproportionate impact of the COVID-19 pandemic on this population.

OBJECTIVES

We examined factors in four domains and hypothesized that poor mental health, negative coping behaviors, negative environmental aspects, and belonging to more vulnerable social groups would be associated with increased substance use during the pandemic.

METHODS

Multiple regression was applied to longitudinal data from a college sample assessed prior (fall 2017 to spring 2019) and during (spring 2020) the pandemic (n= 323; 81.5% cisgender women; 34.5% African-American, 36.1% Asian-American, 15.5% Hispanic/Latinx, 11.8% multi-racial) to identify factors predicting current alcohol, cannabis, and nicotine use frequency (spring 2020) and change in frequency of use between springs 2019 and 2020.

RESULTS

While infrequent substance use (monthly or less) decreased during the pandemic, abstinence rates increased (alcohol 39%; cannabis 18%; nicotine 18%) and higher-frequency alcohol use increased (207%-1600% 2-3 times+/week) compared to spring 2019. The strongest protective factor was change in living situation during the pandemic, associated with lower current alcohol and cannabis use. Risk factors included a history of trouble with police and impulsivity since the pandemic, both associated with higher current and increased alcohol and cannabis use. REM did not differ on most factors and the outcomes. However, a higher percentage of Asian-Americans than other REM reported living situation changes.

CONCLUSION

Substance use rates diverged during the pandemic, with both increased abstinence and higher-frequency use, attributed mostly to mental health and environmental domain factors with few REM differences.

Fit and Tipsy? The Interrelationship between Cardiorespiratory Fitness and Alcohol Consumption and Dependence

PURPOSE

To examine whether higher levels of cardiorespiratory fitness are related to increased alcohol consumption and dependence among a large sample of adults attending a preventive medicine clinic.

METHODS

A cross-sectional study of 38,653 apparently healthy patients who visited the Cooper Clinic (Dallas, TX) for preventive medical examinations (1988-2019) and enrolled in the Cooper Center Longitudinal Study. The primary independent variable was cardiorespiratory fitness, based on a maximal treadmill test, and the dependent variables were alcohol consumption and dependence (self-reported). The relations between fitness category (low, moderate, high) and alcohol consumption (low, moderate, heavy) and suggested alcohol dependence (Cut down, Annoyed, Guilty, Eye opener score ≥2) among women and men were estimated via multivariable regression while adjusting for covariates (e.g., age, birth year cohort, marital status, and body mass index).

RESULTS

Women within the moderate and high fitness categories had 1.58 (95% confidence interval [CI], 1.32-1.91) and 2.14 (95% CI, 1.77-2.58) greater odds of moderate/heavy alcohol consumption, respectively, in comparison to their low fitness counterparts. Similarly, moderate and high fit men had 1.42 (95% CI, 1.30-1.55) and 1.63 (95% CI, 1.49-1.80) times greater odds of moderate-to-heavy alcohol consumption, respectively, in comparison to the low fitness group. In addition, among men who were heavy drinkers (but not women), higher fitness levels were related to lower rates of suggested alcohol dependence. Specifically, these men had 45.7%, 41.7%, and 34.9% proportions of clinically relevant alcohol problems across low, moderate, and high fitness categories (adjusted P for trend <0.001).

CONCLUSIONS

Higher fitness levels are significantly related to greater alcohol consumption among a large cohort of adult patients. Interventions focusing on increasing fitness (via physical activity promotion) might consider concurrently aiming to reduce alcohol consumption.

At home and online during the early months of the COVID-19 pandemic and the relationship to alcohol consumption in a national sample of U.S. adults

Introduction

The current study aimed to understand the links between social media use and alcohol consumption during the early months of the COVID-19 pandemic.

Method

Data were from the national Understanding American Study, a probability-based Internet panel weighted to represent the U.S. population. Subjects (N = 5874; 51% female) were adults, 18 years and older, who completed a March survey (wave 1) and a follow-up survey one month later (wave 3). Analyses assessed the relationships of social media use at wave 1 with wave 3 alcohol use frequency, accounting for wave 1 alcohol use frequency and the sociodemographic characteristics of the sample. Two alcohol use change variables were also assessed as outcomes–increased and decreased alcohol use between waves. We considered the effect of work status changes (working/studying from home and job loss) as potential moderators.

Results

Twitter and Instagram users and users of multiple social media platforms, but not Facebook users, drank more frequently at wave 3. The results were similar when assessing relationships between social media use and increased alcohol use between waves. For Instagram users, more frequent alcohol use at wave 3 was at least partially attributed to drinking frequency at wave 1. Additionally, working/studying from home at wave 3 and employment (rather than job loss) were associated with greater consumption. The interaction effect between Twitter use and working/studying from home was statistically significant in association with alcohol use frequency at wave 3, as was the interaction effect between using multiple platforms and working/studying from home in association with decreased alcohol use between waves.

Discussion

Exposure to content about COVID-19 and increased alcohol consumption during the pandemic may have contributed to more frequent alcohol use for some social media users. The study of public health messaging via social media to change alcohol use behaviors during traumatic events is warranted.

Long-term weight loss success and the health behaviours of adults in the USA: findings from a nationally representative cross-sectional study

OBJECTIVE

To describe the relationship between long-term weight loss (LTWL) success and lifestyle behaviours among US adults.

DESIGN

Serial cross-sectional data from National Health and Nutrition Examination Survey cycles 2007-2014.

SETTING AND PARTICIPANTS

Population-based nationally representative sample. The analytic sample included 3040 adults aged 20-64 years who tried to lose weight in the past year.

MEASURES

Participants were grouped into five LTWL categories (<5%, 5%-9.9%, 10%-14.9%, 15%-19.9% and ≥20%). Lifestyle-related behaviours included the following: alcohol intake, physical activity, smoking, fast-food consumption, dietary quality (Healthy Eating Index (HEI)) and caloric intake. Multivariable regression was employed adjusting for age, sex, race/ethnicity, marital status, education, household income and size, current body mass index and self-reported health status.

RESULTS

Individuals in the 15%-19.9% LTWL group differed significantly from the reference group (<5% LTWL) in their physical activity and dietary quality (HEI) but not caloric intake. Specifically, they had a higher HEI score (β=3.19; 95% CI 0.39 to 5.99) and were more likely to meet physical activity guidelines (OR=1.99; 95% CI 1.11 to 3.55). In comparison, the ≥20% LTWL group was significantly more likely to smoke (OR=1.63; 95% CI 1.03 to 2.57) and to consume lower daily calories (β=-202.91; 95% CI -345.57 to -60.25) than the reference group; however, dietary quality and physical activity did not significantly differ.

CONCLUSION

Among a national sample of adults, a higher level of LTWL success does not necessarily equate to healthy weight loss behaviours. Future research should attempt to design interventions aimed at facilitating weight loss success while encouraging healthy lifestyle behaviours.

Adverse childhood experience patterns, major depressive disorder, and substance use disorder in older adults

OBJECTIVES

This article investigates distinct patterns of adverse childhood experiences (ACEs) in a representative sample of US older adults, and how the ACEs patterns relate to major depression and substance use disorder (SUD).

METHODS

Data came from the National Epidemiologic Survey on Alcohol and Related Conditions III. The study sample consisted of older adults aged 55 or older (N = 11,386). The dependent variable was past-year SUD measuring any DSM-5 diagnosis for alcohol, tobacco, cannabis, and other illicit drugs. The independent variables were the classes of ACEs identified using 11 types of early adversities. The mediating variable was past-year major depressive disorder. We conducted a latent class analysis (LCA) to identify latent classes of ACEs, estimated the relationships between the ACEs classes, major depressive disorder, and SUD, and tested mediation by major depression.

RESULTS

Results of the LCA identified four classes of ACEs: High Adversity (6%), Low Adversity (69%), Child Abuse (16%), and Parental Substance Use (8%). The three classes of High Adversity, Child Abuse, and Parental Substance Use showed significantly higher rates of SUD than the Low Adversity class. The High Adversity and Child Abuse classes were more likely to have major depression compared to the Low Adversity class. In addition, major depression mediated the association between ACEs and SUD for those two classes.

CONCLUSION

The findings provide evidence for a long-term impact of ACEs on mental health and SUD later in life and emphasize trauma-informed care principles in interventions for older adults with SUD.

Intersection of familial risk and environmental social control on high-risk drinking and alcohol dependence in a US national sample of adults

BACKGROUND

Effects of a family history of alcoholism may be moderated by area-level social control factors. We examine whether increased neighborhood alcohol availability (low social control environment) or increased presence of religious adherents in the county (high social control environment) interact with family history in relation to alcohol outcomes.

METHODS

Weighted data from 12,686 adult drinkers (51% male; mean age 44; 80% White, 9% Black, 11% Hispanic) in three US National Alcohol Surveys were linked with data on area-level off-premise alcohol availability and adherence to religions with strong prohibitions against drinking. Family history density had four levels (family history negative, extended family only, first-degree relative(s) only, high family density). Dichotomous outcomes were past-year high-risk drinking and alcohol dependence. Logistic regression models with interaction terms assessed whether associations of family history with alcohol outcomes differed significantly by area-level social control. Stratified models assessed differences by sex and by race/ethnicity.

RESULTS

In the full sample, effects of first-degree relatives and high family density on high-risk drinking strengthened as alcohol availability increased. This was replicated in the subsample of women and suggested in relation to dependence among men and Black drinkers. For White drinkers, higher religious social control reduced effects of first-degree relatives on high-risk drinking.

CONCLUSIONS

Low social control-in particular, greater density of off-premise alcohol outlets-appears to exacerbate effects of a family history of alcoholism on high-risk drinking. Policy makers should consider differential benefits of decreasing alcohol availability for people from high-risk families to reduce high-risk drinking and alcohol problems.

Recruiting for diversity: a pilot test of recruitment strategies for a national alcohol survey with mail-in genetic data collection

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.

College students' use of strategies to hide facial flushing: A target for alcohol education

Alcohol-related facial flushing occurs in individuals who are unable to metabolize ethanol effectively and is associated with increased cancer risk. This study describes college students' understanding of the meaning of flushing for how much alcohol a person should drink and their use of over-the-counter medications and other strategies to reduce its visible effects. Participants: The sample includes 335 White and Asian college students who reported facial flushing after an alcoholic drink. Methods: Students completed an online survey in the spring of their junior year. Results: Most students reported that flushing had no special meaning for drinking or that they did not know what it meant. Six percent reported ever using strategies to hide facial flushing; they were mostly Asian, and those using these strategies drank more alcohol. Conclusions: Findings identify a need for targeted alcohol education with Asian college students who drink alcohol despite experiencing the flushing response.

Exploring how Family and Neighborhood Stressors Influence Genetic Risk for Adolescent Conduct Problems and Alcohol Use

Previous research suggests that genetic risk factors may predispose to conduct problems and alcohol use in adolescence. Whether genetic risk factors interact with social contexts has not been well characterized among African American adolescents. Data came from a subsample of the Genes, Environment, and Neighborhood Initiative study comprising 501 African American adolescents, including 151 lifetime drinkers (56% female, mean age = 16.3, SD = 1.4). Genetic risk was assessed with polygenic risk scores for alcohol dependence. Analyses explored interactions between genetic risk and self-reported alcohol use, conduct problems, life stressors, and other covariates. The effects of two gene-environment interactions (G × E) were tested in the sample of alcohol exposed adolescents; one on conduct problems and the other on alcohol use. There were significant associations between polygenic risk for alcohol dependence and conduct problems. A significant G × E interaction showed the impact of genetic risk on conduct problems was stronger under conditions of high exposure to family and neighborhood stressors. Among this sample of African American adolescents, genetic risk for alcohol dependence was not directly associated with alcohol use but was related to more conduct problems. Further, the effect of genetic risk interacted with stressors from the family and neighborhood, so that the effect of genetic risk on conduct problems was stronger for individuals who reported greater stressors.

Alcohol Metabolizing Polygenic Risk for Alcohol Consumption in European American College Students

OBJECTIVE

Evidence suggests that the nature and magnitude of some genetic effects on alcohol use vary by age. We tested for moderation in the effect of an alcohol metabolizing polygenic score by time across the college years.

METHOD

Participants (total n = 2,214) were drawn from three cohorts of undergraduate college students, who were assessed annually for up to 4 years starting in their freshman year. Polygenic risk scores (PRSs) were calculated from genes involved in the metabolism of alcohol, as many of these markers are among the best replicated in association studies examining alcohol use phenotypes. Linear mixed effects models were fit by maximum likelihood to test the main effects of time and the PRS on alcohol consumption, as well as moderation of the PRS effect on alcohol consumption by time.

RESULTS

In the main effects model, the fixed effects for time and the PRS were positively associated with alcohol consumption. The interaction term testing moderation of the PRS effect by time reached statistical significance and remained statistically significant after other relevant interaction effects were controlled for. The main effect of the PRS accounted for 0.2% of the variance in alcohol consumption, whereas the interaction of PRS effect and time accounted for 0.05%.

CONCLUSIONS

Alcohol metabolizing genetic effects on alcohol use appear to be more influential in later years of college than in earlier years. Shifting environmental contexts, such as increased access to alcohol as individuals approach the legal age to purchase alcohol, may account for this association.

Conclusion: Special issue on genetic and alcohol use disorder research with diverse racial/ethnic groups: Key findings and potential next steps

BACKGROUND AND OBJECTIVES

This special issue brings together papers focusing on a wide range of topics relevant to the research and understanding of the role of race/ethnicity and genetic variation for the susceptibility of developing an alcohol use disorder (AUD).

METHODS

The key findings from the issue's 10 articles are reviewed and organized here around three topics: I: addictive behaviors and potential environmental influences; II: a focus on four racial/ethnic groups; and III: special methodologies.

RESULTS

Several potential next steps in improving effective research strategies are highlighted: (1) implementing best practices for outreach and community engagement may reduce reluctance to participate; (2) recruiting adequately sized and racially/ethnically diverse samples will require new collaborations with investigators who successfully work in diverse communities; (3) identifying and assessing environmental influences that are both unique to, and common among, racial/ethnic groups may inform preventions for AUD; (4) use of standardized measures will facilitate the generation of larger samples and meta-analysis of research findings; and (5) use of better analytic approaches and experimental methods will improve replication in gene finding research and help advance new areas of research.

CONCLUSIONS

Genetic research of AUD in diverse racial/ethnic populations is advancing. The articles in this issue examined the general theme of including diverse population groups in genetic studies and offered potential strategies for addressing some common problems.

SCIENTIFIC SIGNIFICANCE

Greater inclusion of diverse racial/ethnic populations in this research is important to ensure that the benefits of new knowledge and technology are equally shared. (Am J Addict 2017;26:532-537).

ALDH2*2 and peer drinking in East Asian college students

BACKGROUND

The ALDH2*2 allele (A-allele) at rs671 is more commonly carried by Asians and is associated with alcohol-related flushing, a strong adverse reaction to alcohol that is protective against drinking. Social factors, such as having friends who binge drink, also contribute to drinking in Asian youth.

OBJECTIVES

This study examined the interplay between ALDH2*2, peer drinking, and alcohol consumption in college students. We hypothesized that the relationship between ALDH2*2 and standard grams of ethanol per month would vary based on the level of peer drinking.

METHODS

Subjects (N = 318, 63.25% female) were East Asian college students in the United States who reported drinking alcohol. Data were from the freshman year of a university survey that included a saliva DNA sample. ALDH2*2 status was coded ALDH2*2(+) (A/G and A/A genotypes) and ALDH2*2(-) (G/G genotype). Peer drinking was students' perception of how many of their friends "got drunk".

RESULTS

Main effects of ALDH2*2(-) and having more friends who got drunk were associated with greater alcohol consumption. The ALDH2*2 × peer drunkenness interaction showed a stronger positive association with alcohol consumption for ALDH2*2(-) versus ALDH2*2(+) at increasing levels of peer drunkenness. Follow-up comparisons within each peer drunkenness level identified significantly higher alcohol consumption for ALDH2*2(-) compared to ALDH2*2(+) at the all friends got drunk level.

CONCLUSION

There was evidence of a stronger effect for ALDH2*2(-) compared to ALDH2*2(+) with greater alcohol use when students were more exposed to peer drinking. Findings contribute to a growing literature on the interrelationships between genetic influences and more permissive environments for alcohol consumption.

Review: Environmental influences on alcohol use: Informing research on the joint effects of genes and the environment in diverse U.S. populations

BACKGROUND AND OBJECTIVES

This review aimed to inform the current state of alcohol research on the joint effects of genes and the environment conducted in U.S. racial/ethnic minority populations, focusing on African Americans, Latinos/Hispanics, Asians, and American Indians.

METHODS

A key-word and author-based search was conducted and supplemented with direct contact to researchers in this area to ensure a comprehensive inclusion of published, peer-reviewed studies. These studies were considered in terms of the racial/ethnic population groups, phenotypes, genetic variants, and environmental influences covered. Research findings from alcohol epidemiologic studies were highlighted to introduce some potential environmental variables for future studies of gene and environment (G-E) relationships.

RESULTS

Twenty-six (N = 26) studies were reviewed. They predominantly involved African American and Asian samples and had a very limited focus on Latinos/Hispanics and American Indians. There was a wide range of alcohol-related phenotypes examined, and studies almost exclusively used a candidate gene approach. Environmental influences focused on the most proximate social network relationships with family and peers. There was far less examination of community- and societal-level environmental influences on drinking. Epidemiologic studies informing the selection of potential environmental factors at these higher order levels suggest inclusion of indicators of drinking norms, alcohol availability, socioeconomic disadvantage, and unfair treatment.

CONCLUSIONS

The review of current literature identified a critical gap in the study of environments: There is the need to study exposures at community and societal levels.

SCIENTIFIC SIGNIFICANCE

These initial studies provide an important foundation for evolving the dialogue and generating other investigations of G-E relationships in diverse racial/ethnic groups. (Am J Addict 2017;26:446-460).

Introduction: Special issue on genetic research of alcohol use disorder in diverse racial/ethnic populations

This special issue of The American Journal on Addictions is an extension of a workshop held at the Research Society on Alcoholism (2015) highlighting several important issues related to studies of the genetic bases of alcohol use disorder among racially/ethnically diverse populations. While not exhaustive in their coverage, the papers in this special issue focus on three important topics: (1) the importance of considering the social and environmental context in genetic analyses; (2) social and cultural considerations for engaging diverse communities in genetic research; and (3) methodologies related to phenotype development for use with racially/ethnically diverse populations. A brief overview of each paper included in these three sections is presented. The issue concludes with additional considerations for genetic research with racially/ethnically diverse population groups along with a commentary. (Am J Addict 2017;26:422-423).

Learning from Latino voices: Focus Groups' Insights on Participation in Genetic Research

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. (Am J Addict 2017;26:477-485).

Interrelationship between family history of alcoholism and generational status in the prediction of alcohol dependence in US Hispanics

BACKGROUND

Both a family history of alcoholism and migration-related factors like US v. foreign nativity increase the risk for developing alcohol use disorders in Hispanic Americans. For this study, we integrated these two lines of research to test whether the relationship between familial alcoholism and alcohol dependence changes with successive generations in the United States.

METHOD

Data were from the waves 1 and 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Subjects self-identified Hispanic ethnicity (N = 4122; n = 1784 first, n = 1169 second, and n = 1169 third or later generation) and reported ever consuming ⩾12 drinks in a 1-year period. A family history of alcoholism was assessed in first- and second-degree relatives. Analyses predicting the number of alcohol dependence symptoms were path models.

RESULTS

Alcohol dependence symptoms were associated with a stronger family history of alcoholism and later generational status. There was a significant interaction effect between familial alcoholism and generational status; the relationship of familial alcoholism with alcohol dependence symptoms increased significantly with successive generations in the United States, more strongly in women than men. Acculturation partially mediated the interaction effect between familial alcoholism and generational status on alcohol dependence, although not in the expected direction.

CONCLUSIONS

Familial alcoholism interacted with generational status in predicting alcohol dependence symptoms in US Hispanic drinkers. This relationship suggests that heritability for alcoholism is influenced by a higher-order environmental factor, likely characterized by a relaxing of social restrictions on drinking.

Interactions Between Alcohol Metabolism Genes and Religious Involvement in Association With Maximum Drinks and Alcohol Dependence Symptoms

OBJECTIVE

Variations in the genes encoding alcohol dehydrogenase (ADH) enzymes are associated with both alcohol consumption and dependence in multiple populations. Additionally, some environmental factors have been recognized as modifiers of these relationships. This study examined the modifying effect of religious involvement on relationships between ADH gene variants and alcohol consumption-related phenotypes.

METHOD

Subjects were African American, European American, and Hispanic American adults with lifetime exposure to alcohol (N = 7,716; 53% female) from the Collaborative Study on the Genetics of Alcoholism. Genetic markers included ADH1Brs1229984, ADH1B-rs2066702, ADH1C-rs698, ADH4-rs1042364, and ADH4-rs1800759. Phenotypes were maximum drinks consumed in a 24-hour period and total number of alcohol dependence symptoms according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Religious involvement was defined by self-reported religious services attendance.

RESULTS

Both religious involvement and ADH1B-rs1229984 were negatively associated with the number of maximum drinks consumed and the number of lifetime alcohol dependence symptoms endorsed. The interactions of religious involvement with ADH1B-rs2066702, ADH1C-rs698, and ADH4-rs1042364 were significantly associated with maximum drinks and alcohol dependence symptoms. Risk variants had weaker associations with maximum drinks and alcohol dependence symptoms as a function of increasing religious involvement.

CONCLUSIONS

This study provided initial evidence of a modifying effect for religious involvement on relationships between ADH variants and maximum drinks and alcohol dependence symptoms.

A 10-year study of factors associated with alcohol treatment use and non-use in a U.S. population sample

BACKGROUND

This study seeks to identify changes in perceived barriers to alcohol treatment and predictors of treatment use between 1991-92 and 2001-02, to potentially help understand reported reductions in treatment use at this time. Social, economic, and health trends during these 10 years provide a context for the study.

METHODS

Subjects were Whites, Blacks, and Hispanics. The data were from the National Longitudinal Alcohol Epidemiologic Survey (NLAES) and the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). We conducted two analyses that compared the surveys on: (1) perceived treatment barriers for subjects who thought they should get help for their drinking, and (2) variables predicting past-year treatment use in an alcohol use disorder subsample using a multi-group multivariate regression model.

RESULTS

In the first analysis, those barriers that reflected negative beliefs and fears about seeking treatment as well as perceptions about the lack of need for treatment were more prevalent in 2001-02. The second analysis showed that survey year moderated the relationship between public insurance coverage and treatment use. This relationship was not statistically significant in 1991-92 but was significant and positive in 2001-02, although the effect of this change on treatment use was small.

CONCLUSIONS

Use of alcohol treatment in the U.S. may be affected by a number of factors, such as trends in public knowledge about treatment, social pressures to reduce drinking, and changes in the public financing of treatment.

Alcohol Use Patterns Among Urban and Rural Residents: Demographic and Social Influences

Rates of alcohol use and alcohol use disorder (AUD) vary with geographic location. Research on risks for AUD associated with living in a rural versus urban setting is complicated by the varied systems used to classify geographic location. Studies comparing the prevalence of heavier or binge drinking and AUD based on a dichotomous urban/rural classification have mixed findings when compared with those using more detailed urban-to-rural categories. In addition, urban/rural residence interacts with other demographic factors such as age, U.S. region, and race/ethnicity to affect alcohol use. Social and cultural factors help explain the relationship between geographic location and alcohol use. However, this area of research could be improved by the use of standardized definitions as well as the analysis of a more complete urban-to-rural continuum (e.g., urban, suburban, and rural areas). Having a better understanding of how geographic characteristics influence alcohol use would help inform and improve prevention and treatment efforts.

Explaining the frequency of alcohol consumption in a conflict zone: Jews and Palestinians in Israel

Experiencing stress and exposure to terrorism may have an adverse effect on health risk behaviors. Few studies have examined alcohol use among adults living in Israel under chronic, stressful terrorism-related conditions. In this study, we examined the relationships of demographics, past stressful events, and terrorism exposure to the frequency of alcohol use and the mediating roles of depressive and post-traumatic stress disorder (PTSD) symptoms. We used three waves of data from a 2007-2008 nationally representative sample of Jewish and Palestinian adults in Israel. We assessed past stressful events, in addition to direct and indirect exposures to terrorism. Results indicated that past stressful events and exposure to terrorism were not directly associated with alcohol use, but were indirectly associated and mediated by depressive and PTSD symptomology. Mental health symptoms were differentially associated with alcohol use. More frequent drinking was mediated by higher levels of depression, including for women and Palestinians; however, PTSD symptom severity was related to less frequent drinking. Mental health may play a prominent role in the frequency of alcohol use among adults exposed to terrorism in Israel. Alcohol use, as a coping mechanism, may differ by demographic characteristics (gender and ethnicity) and psychological symptomology for adults living in a conflict zone in Israel.

Men and women from the STRIDE clinical trial: An assessment of stimulant abstinence symptom severity at residential treatment entry

BACKGROUND AND OBJECTIVES

Gender-specific factors associated with stimulant abstinence severity were examined in a stimulant abusing or dependent residential treatment sample (N = 302).

METHOD

Bivariate statistics tested gender differences in stimulant abstinence symptoms, measured by participant-reported experiences of early withdrawal. Multivariate linear regression examined gender and other predictors of stimulant abstinence symptom severity.

RESULTS

Women compared to men reported greater stimulant abstinence symptom severity. Anxiety disorders and individual anxiety-related abstinence symptoms accounted for this difference. African American race/ethnicity was predictive of lower stimulant abstinence severity.

DISCUSSION AND CONCLUSIONS

Women were more sensitive to anxiety-related stimulant withdrawal symptoms.

SCIENTIFIC SIGNIFICANCE

Clinics that address anxiety-related abstinence symptoms, which more commonly occur in women, may improve treatment outcome.

Comorbidities and race/ethnicity among adults with stimulant use disorders in residential treatment

Comorbid physical and mental health problems are associated with poorer substance abuse treatment outcomes; however, little is known about these conditions among stimulant abusers at treatment entry. This study compared racial and ethnic groups on baseline measures of drug use patterns, comorbid physical and mental health disorders, quality of life, and daily functioning among cocaine and stimulant abusing/dependent patients. Baseline data from a multi-site randomized clinical trial of vigorous exercise as a treatment strategy for a diverse population of stimulant abusers (N=290) were analyzed. Significant differences between groups were found on drug use characteristics, stimulant use disorders, and comorbid mental and physical health conditions. Findings highlight the importance of integrating health and mental health services into substance abuse treatment and could help identify potential areas for intervention to improve treatment outcomes for racial and ethnic minority groups.

Do stressful events account for the link between socioeconomic status and mental health?

BACKGROUND

The purpose of this study was to prospectively examine the relationships between socioeconomic status (SES), demographic variables and mental health and to determine whether number of life stressors mediated these relationships.

METHODS

Wave 1 (2001-02) and 2 (2004-05) data from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; n = 34,459) were used in the current study. Controlling for wave 1 mental health, a mediation model was tested to determine the relative impact of socioeconomic and demographic variables (all measured at wave 1) on mental health 3 years later (wave 2). The number of life stressors experienced in the 12 months prior to wave 1, assessed at wave 1, was evaluated as the mediator.

RESULTS

Findings indicated that SES, age, race/ethnicity, gender and marital status independently predicted changes in mental health ratings at wave 2. In addition, the number of life stressors mediated the relation between socioeconomic and demographic variables and mental health. Exposure to life stressors helps to explain commonly reported socioeconomic and demographic disparities in mental health.

CONCLUSIONS

Findings may suggest that reducing exposure to stressors and/or improving coping with life stressors may both improve mental health and reduce health disparities.

Characteristics of adults involved in alcohol-related intimate partner violence: results from a nationally representative sample

BACKGROUND

More than 12 million women and men are victims of partner violence each year. Although the health outcomes of partner violence have been well documented, we know very little about specific event-level characteristics that may provide implications for prevention and intervention of partner violence situations. Therefore, the purpose of this study is to evaluate substance abuse and dependence as risk factors for event-level alcohol-related intimate partner violence (IPV).

METHODS

Data were derived from Wave II of the National Epidemiological Survey on Alcohol and Related Conditions (2004-2005). Eligible participants (N = 2,255) reported IPV the year before the survey. Negative binomial and ordinal regression methods were used to assess risk factors for alcohol use during IPV.

RESULTS

Respondent PTSD was the only mental health diagnosis related to alcohol use during IPV (OR = 1.45). Marijuana use was related to respondents' use of alcohol during IPV (OR = 2.68). Respondents' meeting the criteria for alcohol abuse/dependence was strongly associated with respondent drinking (OR = 10.74) and partner drinking (OR = 2.89) during IPV.

CONCLUSION

Results indicate that PTSD, marijuana use disorders, alcohol abuse and dependence are associated with more frequent alcohol use during IPV. In addition, it is important to consider that the patient who presents in emergency settings (e.g., hospitals or urgent care facilities) may not be immediately identifiable as the victim or the perpetrator of partner violence. Therefore, screening and intervention programs should probe to further assess the event-level characteristics of partner violence situations to ensure the correct service referrals are made to prevent partner violence.

Framing ethnic variations in alcohol outcomes from biological pathways to neighborhood context

BACKGROUND

Health disparities research seeks to eliminate disproportionate negative health outcomes experienced in some racial/ethnic minority groups. This brief review presents findings on factors associated with drinking and alcohol-related problems in racial/ethnic groups.

METHODS

Those discussed are as follows: (i) biological pathways to alcohol problems, (ii) gene × stress interactions, (iii) neighborhood disadvantage, stress, and access to alcohol, and (iv) drinking cultures and contexts.

RESULTS

These factors and their interrelationships are complex, requiring a multilevel perspective.

CONCLUSIONS

The use of interdisciplinary teams and an epigenetic focus are suggested to move the research forward. The application of multilevel research to policy, prevention, and intervention programs may help prioritize combinations of the most promising intervention targets.

Focus on: ethnicity and the social and health harms from drinking

Alcohol consumption is differentially associated with social and health harms across U.S. ethnic groups. Native Americans, Hispanics, and Blacks are disadvantaged by alcohol-attributed harms compared with Whites and Asians. Ethnicities with higher rates of risky drinking experience higher rates of drinking harms. Other factors that could contribute to the different effects of alcohol by ethnicity are social disadvantage, acculturation, drink preferences, and alcohol metabolism. This article examines the relationship of ethnicity and drinking to (1) unintentional injuries, (2) intentional injuries, (3) fetal alcohol syndrome (FAS), (4) gastrointestinal diseases, (5) cardiovascular diseases, (6) cancers, (7) diabetes, and (8) infectious diseases. Reviewed evidence shows that Native Americans have a disproportionate risk for alcohol-related motor vehicle fatalities, suicides and violence, FAS, and liver disease mortality. Hispanics are at increased risk for alcohol-related motor vehicle fatalities, suicide, liver disease, and cirrhosis mortality; and Blacks have increased risk for alcohol-related relationship violence, FAS, heart disease, and some cancers. However, the scientific evidence is incomplete for each of these harms. More research is needed on the relationship of alcohol consumption to cancers, diabetes, and HIV/AIDS across ethnic groups. Studies also are needed to delineate the mechanisms that give rise to and sustain these disparities in order to inform prevention strategies.

Epidemiology of drinking, alcohol use disorders, and related problems in US ethnic minority groups

This chapter reviews selected epidemiologic studies on drinking and associated problems among US ethnic minorities. Ethnic minorities and the White majority group exhibit important differences in alcohol use and related problems, including alcohol use disorders. Studies show a higher rate of binge drinking, drinking above guidelines, alcohol abuse, and dependence for major ethnic and racial groups, notably, Blacks, Hispanics, and American Indians/Alaskan Natives. Other problems with a higher prevalence in certain minority groups are, for example, cancer (Blacks), cirrhosis (Hispanics), fetal alcohol syndrome (Blacks and American Indians/Alaskan Natives), drinking and driving (Hispanics, American Indians/Alaskan Natives). There are also considerable differences in rates of drinking and problems within certain ethnic groups such as Hispanics, Asian Americans, and American Indians/Alaskan Natives. For instance, among Hispanics, Puerto Ricans and Mexican Americans drink more and have higher rates of disorders such as alcohol abuse and dependence than Cuban Americans. Disparities also affect the trajectory of heavy drinking and the course of alcohol dependence among minorities. Theoretic accounts of these disparities generally attribute them to the historic experience of discrimination and to minority socioeconomic disadvantages at individual and environmental levels.

Cardiorespiratory fitness, alcohol intake, and metabolic syndrome incidence in men

PURPOSE

The objective of this study is to prospectively examine the independent and joint effects of alcohol consumption and cardiorespiratory fitness on the incidence of metabolic syndrome (MetS) in a cohort of men.

METHODS

A prospective examination was done of 3411 apparently healthy men at baseline, who came to the Cooper Clinic (Dallas, TX) for at least two preventive visits (1979-2010). Primary exposure variables were cardiorespiratory fitness and alcohol intake; the outcome measure was MetS and the components thereof. Cox proportional hazards models were computed to assess the relation between the exposure variables and the incidence of MetS while adjusting for confounders.

RESULTS

For a mean follow-up period of 9 yr (SD = 7.8), 276 men developed MetS. In multivariable analysis, a dose-response relationship was observed between increased levels of fitness and reduced MetS risk (moderate fitness: HR = 0.60; 95% confidence interval (CI), 0.43-0.82; high fitness: HR = 0.49, 95% CI, 0.35-0.69). When examining the independent effects of alcohol, light drinking increased the risk for MetS by 66% (HR = 1.66, 95% CI, 1.11-2.48). No statistically significant interaction effect was observed between alcohol and fitness in relation to MetS (P = 0.32). When assessing the relation between each exposure and the components of MetS, higher fitness consistently reduced the risk of all components, whereas lower alcohol intake reduced the risk of elevated glucose and blood pressure and increased the risk for low HDL cholesterol.

CONCLUSIONS

Among this cohort of men, higher fitness levels reduced the risk for MetS and its components. The relation between alcohol intake levels and metabolic risk was more complex and not reflected when examining MetS as a whole.

Ethnicity and gender comparisons of health consequences in adults with alcohol dependence

The moderating effects of ethnicity and gender on factors associated with physical health consequences in adults manifesting alcohol dependence were examined using data from the 2001-2002 US National Epidemiologic Survey on Alcohol and Related Conditions (NESARC). Black and white respondents with a lifetime diagnosis of DSM-IV alcohol dependence were selected for the study (n = 3,852). A multiple-group structural equation model tested ethnicity, gender, and intervening variables as predictors of physical health status in alcohol-dependent men and women. Study findings offer implications for clinical practice with alcohol-dependent individuals by identifying likely target groups and problems for intervention.

Genetics of alcohol dependence and social work research: do they mix?

Since completion of the mapping of the human genome in early 2000, tremendous progress has been made in the identification of many different genes associated with our health and across diseases. Although social work researchers are not expected to conduct genetic research at the molecular level, it is imperative that we are able to understand the basic genetic findings related to behavioral problems and are able to translate and integrate this information into psychosocial treatment approaches and program development. This article is an introduction and overview of genetic approaches, using studies of the genetics of alcoholism to exemplify important issues. The literature review is not comprehensive and focuses primarily on the Collaborative Study on the Genetics of Alcoholism project as an example of a multidisciplinary and integrative approach to the genetic study of a major health problem often encountered in social work practice.

Alcohol availability and neighborhood poverty and their relationship to binge drinking and related problems among drinkers in committed relationships

The authors examined the relationship of alcohol outlet density (AOD) and neighborhood poverty with binge drinking and alcohol-related problems among drinkers in married and cohabitating relationships and assessed whether these associations differed across sex. A U.S. national population couples survey was linked to U.S. Census data on AOD and neighborhood poverty. The 1,784 current drinkers in the survey reported on their binge drinking, alcohol-related problems, and other covariates. AOD was defined as the number of alcohol outlets per 10,000 persons and was obtained at the zip code level. Neighborhood poverty was defined as having a low (<20%) or high (≥20%) proportion of residents living in poverty at the census tract level. We used logistic regression for survey data to estimate odds ratios and 95% confidence intervals and tested for differences of associations by sex. Associations of neighborhood poverty with binge drinking were stronger for male than for female drinkers. The association of neighborhood poverty with alcohol-related problems was also stronger for men than for women. We observed no relationships between AOD and binge drinking or alcohol-related problems in this couples survey. Efforts to reduce binge drinking or alcohol-related problems among partners in committed relationships may have the greatest impact if targeted to male drinkers living in high-poverty neighborhoods. Binge drinking and alcohol-related problems, as well as residence in an impoverished neighborhood are risk factors for intimate partner violence (IPV) and other relationship conflicts.

Intimate partner violence and alcohol problems in interethnic and intraethnic couples

Despite the growing number of interethnic marriages in the United States, few studies have examined intimate partner violence (IPV) in interethnic couples. This article examined past-year occurrences of IPV across interethnic and intraethnic couples and tested correlates of IPV specifically in interethnic couples. Data were from a national survey of couples 18 years of age and older from the 48 contiguous states. Interethnic couples (n = 116) included partners from different ethnic backgrounds, including Black-White, Hispanic-White, and Black-Hispanic couples. White (n = 555), Black (n = 358), and Hispanic (n = 527) intraethnic couples included partners with the same ethnicity. Data analyses were prevalence rates and logistic regressions. The analysis showed that interethnic couples were comparatively younger and had shorter relationships than intraethnic White, Black, and Hispanic couples. Male partners in interethnic couples had higher rates of binge drinking and alcohol problems compared with male partners in intraethnic couples. Past-year prevalence rates for any occurrence of IPV and acts of severe IPV were higher for interethnic couples relative to intraethnic couples. Most occurrences of IPV for interethnic couples were mutual. Factors predicting IPV among interethnic couples included marital status, couples' age, male alcohol problems, and female impulsivity. Mounting evidence points to interethnic couples as a high-risk group for IPV. Interethnic couples may be at greater risk for IPV because of their younger age, binge drinking, and alcohol problems. Future research could build on this study by examining cohort effects and regional differences in IPV for interethnic couples and the risk for IPV across interethnic couples of different ethnic compositions.

Cardiorespiratory fitness, alcohol, and mortality in men: the Cooper Center longitudinal study

BACKGROUND

Studies have found that higher levels of cardiorespiratory fitness and light to moderate alcohol intake reduce the risk for premature death. Scant evidence, however, exists assessing the joint effects of both measures on all-cause and cardiovascular disease (CVD) mortality.

PURPOSE

This study aims to examine the independent and joint effects of alcohol consumption and cardiorespiratory fitness on all-cause and cardiovascular-related mortality in a large cohort of men.

METHODS

This prospective study included 29,402 men who came to the Cooper Clinic (Dallas, TX) for a preventive medicine visit from 1973 to 2006. Data were analyzed in 2011. The primary exposure variables were tertiles of cardiorespiratory fitness and four categories of alcohol consumption, and the outcomes were all-cause and CVD mortality. Cox proportional hazards regression was used to model the association between alcohol intake, cardiorespiratory fitness, and all-cause and CVD mortality, controlling for potential confounders.

RESULTS

A total of 1830 (all-cause) and 523 (CVD) deaths occurred in men over an average follow-up period of 17.4 years (SD=9.1). A linear relationship was observed (p<0.001) between increased fitness and reduced all-cause and CVD mortality. Specifically, moderate and high levels of fitness reduced the risk for all-cause mortality (HR=0.67, 95% CI=0.60, 0.74, and HR=0.57, 95% CI=0.49, 0.67, respectively) and CVD mortality in comparison to the low-fitness reference group (HR=0.70, 95% CI=0.57, 0.85; HR=0.54, 95% CI=0.40, 0.75, respectively), while controlling for alcohol intake and other covariates. A significant curvilinear relationship was found (p=0.01) between alcohol intake and all-cause mortality (but not CVD mortality), while controlling for fitness and other covariates. In a categoric examination of alcohol intake and mortality, adjusting for fitness and other confounders, there was no statistically significant effect of light drinking compared to heavy drinking on all-cause mortality or CVD mortality. An examination of the joint effects of fitness and alcohol on all-cause mortality showed that moderate and high fitness levels were protective against mortality irrespective of alcohol consumption levels. Few significant combined effects for CVD mortality reduction were found.

CONCLUSIONS

Alcohol consumption did not significantly modify the association between fitness and mortality in this large cohort of men.

Trends in alcohol services utilization from 1991-1992 to 2001-2002: ethnic group differences in the U.S. population

BACKGROUND

During the early 1990s in the United States, changes to the provision and financing of alcohol treatment services included reductions in inpatient treatment services and in private sector spending for treatment. We investigated trends in alcohol services utilization over the 10-year period from 1991-1992 to 2001-2002 among U.S. whites, blacks, and Hispanics.

METHODS

Data come from 2 household surveys of the U.S. adult population. The 1991 to 1992 National Longitudinal Alcohol Epidemiologic Survey and the 2001 to 2002 National Epidemiologic Survey on Alcohol and Related Conditions conducted face-to-face interviews with a multistage cluster sample of individuals 18 years of age and older in the continental United States. Treatment utilization represented both total utilization and the use of alcohol services. Data analyses were prevalence rates and multivariate logistic regressions for lifetime utilization with drinkers and individuals with alcohol use disorders (AUDs).

RESULTS

From 1991-1992 to 2001-2002, drinking-related emergency room and human services use increased for drinkers, while total utilization and the use of private health professional services and mutual aid decreased for individuals with AUDs. In drinkers and individuals with AUDs, blacks and Hispanics were less likely than whites to use private health professional care. Hispanics with AUDs were less likely than whites with AUDs to use alcohol or drug programs. Ethnicity interacted with alcohol severity to predict alcohol services utilization. At higher levels of alcohol severity, blacks and Hispanics were less likely than whites to ever use treatment and to use alcohol services (i.e., human services for Hispanic drinkers, mental health services for blacks with AUDs, and mutual aid for Hispanics with AUDs).

CONCLUSIONS

Our findings showed increases from 1991-1992 to 2001-2002 in alcohol services utilization for drinkers, but reductions in utilization for individuals with AUDs. Blacks and Hispanics, particularly those at higher levels of alcohol severity, underutilized treatment services compared to whites. These utilization trends for blacks and Hispanics may reflect underlying disparities in healthcare access for minority groups, and language and logistical barriers to utilizing services.

Ten-year trends (1992 to 2002) in sociodemographic predictors and indicators of alcohol abuse and dependence among whites, blacks, and Hispanics in the United States

BACKGROUND

The objective of this paper is to examine 10-year trends (1992 to 2002) in the number and type of indicators of DSM-IV abuse and dependence among whites, blacks, and Hispanics in the United States.

METHODS

Data are from the 1991 to 1992 National Longitudinal Alcohol Epidemiologic Survey (NLAES; n = 42,862) and the 2001 to 2002 National Epidemiologic Study on Alcohol and Related Conditions (NESARC; n = 43,093). Both surveys used multistage cluster sample procedures to select respondents 18 years of age and older from the U.S. household population.

RESULTS

Increases in the prevalence of alcohol abuse between 1992 and 2002 seem associated with a rise in the prevalence of the indicator for "hazardous use." which usually means reports of driving after drinking. The decrease in dependence was not associated with changes in a particular indicator. In addition, both in 1992 and 2002, 12.3 to 15.4% of the men and 5.2 to 7.9% of the women were diagnostic "orphans." These respondents reported 1 or 2 indicators of alcohol dependence as present.

CONCLUSIONS

The observed trends in number and types of indicators of DSM-IV alcohol abuse and dependence were probably triggered by a complex interplay between individuals' volume and pattern of drinking and reactions from the drinkers' social environment. The close association between hazardous use of alcohol and the prevalence of abuse deserves further discussion. A medical diagnostic category should not be so dependent on a criterion that may be influenced by social situations. It is necessary to understand more about diagnostic "orphans" to better design interventions to address their problems.

Alcohol problems in young adults transitioning from adolescence to adulthood: The association with race and gender

Race and gender may be important considerations for recognizing alcohol related problems in Black and White young adults. This study examined the prevalence and age of onset of individual alcohol problems and alcohol problem severity across race and gender subgroups from a longitudinal study of a community sample of adolescents followed into young adulthood (N=166; 23-29 yrs. old who were drinkers). All alcohol problems examined first occurred when subjects were in their late teens and early 20s. Drinking in hazardous situations, blackouts, and tolerance were the most common reported alcohol problems. In race and gender comparisons, more males than females experienced alcohol problems. Blacks generally had a later age of onset of alcohol problems. Multivariate regressions showed greater alcohol problem severity in males compared to females, but no significant differences between Blacks and Whites. Education, family environment and earlier alcohol use behaviors and expectancies were reliable predictors of alcohol problem severity in young adulthood. White males were at particular risk for experiencing more severe alcohol problems. Findings may inform the design of more targeted interventions for alcohol problems in different populations.

Development and Vulnerability Factors in Adolescent Alcohol Use

This article provides an overview of the characteristics of adolescent alcohol use, normative and subgroup variations in drinking behavior, and the important factors associated with an increased risk for developing alcohol problems in later adolescence and young adulthood. Parental or family histories of alcoholism, temperament traits, conduct problems, cognitive functioning, alcohol expectancies, and peer and other social relations are identified as factors influencing an adolescent's susceptibility for initiating a variety of alcohol use behaviors. The deviance prone model, proposed by Sher in 1991, is presented as an important tool for testing possible relationships among the various risk factors and their sequencing that leads to early adolescent alcohol use and drug initiation. It is also possible to extend the model to allow for an examination of the complex interplay of risk factors that lead to the development of alcohol use problems in late adolescence and young adults.

Impulsive aggression in attention-deficit/hyperactivity disorder: symptom severity, co-morbidity, and attention-deficit/hyperactivity disorder subtype

OBJECTIVE

The aim of this study was to characterize aggression and its relationship to psychiatric co-morbidity, attention-deficit/hyperactivity disorder (ADHD) subtype, and ADHD symptom severity in clinically referred ADHD youngsters. We also wanted to ascertain whether reactive and impulsive aggression is more prevalent than proactive aggression in an ADHD sample.

METHOD

Consecutively referred ADHD children and adolescents (n = 268) and community controls (n = 100) were assessed systematically regarding demographics, psychiatric diagnosis, overt aggression severity, proactive and reactive aggression severity, and ADHD symptom severity using correlational analysis and analysis of covariance (ANCOVA).

RESULTS

Across all aggression measures, ADHD children were more aggressive than community controls. ADHD children with nonanxiety co-morbid disorders were more aggressive than ADHD children without such co-morbidity. The number of co-morbid psychiatric diagnoses and ADHD symptom severity were significantly associated with aggression. ADHD youngsters demonstrated significantly more reactive than proactive forms of aggression across all co-morbid diagnoses.

CONCLUSIONS

Aggression is common in clinically referred ADHD youngsters and should be identified as a legitimate target for psychopharmacological treatment in children and adolescents with moderate to severe ADHD and nonanxiety co-morbid diagnostic disorders.

Strengthening Family Practices for Latino Families

The study examined the effectiveness of a culturally-adapted Strengthening Families Program (SFP) for Latinos to reduce risks for alcohol and drug use in children. Latino families, predominantly Puerto Rican, with a 9-12 year old child and a parent(s) with a substance abuse problem participated in the study. Pre- and post-tests were conducted with each family. Parental stress, parent-child dysfunctional relations, and child behavior problems were reduced in the families receiving the intervention; family hardiness and family attachment were improved. Findings contribute to the validation of the SFP with Latinos, and can be used to inform social work practice with Puerto Rican families.

Ethnicity and adolescent pathways to alcohol use

OBJECTIVE

This study examined the influence of ethnicity on factors affecting alcohol-use behaviors in a community sample of white, black, and Hispanic youth (N = 323). Conduct problems, positive alcohol expectancies, and socioeconomic status were expected to mediate the effect of negative affectivity and a paternal history of substance dependence on the age at onset of regular drinking and the frequency of drinking.

METHOD

Subjects ages 14-21 (57.9% female; 60.7% white) were interviewed along with their fathers at baseline (Time 1), and subjects only were interviewed again 5 years later (Time 2). A structural equation model was used to test a deviance proneness model for predicting drinking behaviors and to evaluate differences on model paths by ethnicity.

RESULTS

Ethnic group membership moderated mediational pathways linked to the onset of regular alcohol use but not to drinking frequency. An increase in the number of childhood conduct problems predicted an earlier age at onset of regular drinking for blacks, whereas more positive alcohol expectancies were associated with an earlier initiation of regular drinking for whites and Hispanics.

CONCLUSIONS

Findings from this study provide evidence that risk factors for alcohol use in adolescents and young adults vary according to ethnic group.
