Adolescent tobacco use and substance abuse treatment outcomes

This study investigated the relationship between cigarette-smoking status and 12-month alcohol and marijuana treatment outcomes in a sample of 1,779 adolescents from the Drug Abuse Treatment Outcomes Study for Adolescents. Participants were classified into four groups based on change in cigarette-smoking status from intake to the 12-month follow-up: persistent smokers, nonsmokers, quitters, and smoking initiators. Logistic regression was used to predict likelihood of relapse to alcohol, marijuana, and other drugs after controlling for intake levels and demographic/treatment characteristics. Results found persistent smokers and smoking initiators to have significantly greater odds of alcohol and marijuana relapse compared with quitters. Furthermore, persistent smokers and smoking initiators were also found to have distinctively shorter periods to marijuana relapse at follow-up. Implications for the implementation of tobacco cessation treatment in the context of substance abuse treatment for adolescents are discussed.

Religiosity, Alcohol Use Attitudes, and Alcohol Use in a National Sample of Adolescents

The purpose of this study was to investigate alcohol use attitudes as a mediator of the relationship between religiosity and the frequency of past month alcohol use in a national sample of adolescents. Data were drawn from 18,314 adolescents who participated in the 2006 and 2007 National Survey on Drug Use and Health. Variables included religiosity, alcohol use attitudes, and past month frequency of alcohol use. Structural equation modeling was used to test alcohol use attitudes as a mediator of the relationship between religiosity and frequency of alcohol use and to test model invariance across 4 racial/ethnic groups. Results suggest that alcohol use attitudes partially mediate the relationship between religiosity and frequency of alcohol use. Furthermore, while the pattern of these relationships is similar across racial/ethnic groups, the magnitude of alcohol use attitudes on frequency of alcohol use differed. Implications for prevention programs include targeting alcohol use attitudes in a variety of settings.

Risks for early substance involvement associated with parental alcoholism and parental separation in an adolescent female cohort

BACKGROUND We examined timing of substance involvement as a joint function of parental history of alcoholism and parental separation during childhood. METHOD Data were drawn from a large cohort of female like-sex twins [n=613 African Ancestry (AA), n=3550 European or other ancestry (EA)]. Cox proportional hazards regression was conducted predicting age at first use of alcohol, first alcohol intoxication, first use and regular use of cigarettes, and first use of cannabis and other illicit drugs from dummy variables coding for parental alcoholism and parental separation. Propensity score analysis was also conducted comparing intact and separated families by predicted probability of parental separation. RESULTS In EA families, increased risk of substance involvement was found in both alcoholic and separated families, particularly through ages 10 or 14 years, with risk to offspring from alcoholic separated families further increased. In AA families, associations with parental alcoholism and parental separation were weak and with few exceptions statistically nonsignificant. While propensity score findings confirmed unique risks observed in EA families, intact and separated AA families were poorly matched on risk-factors presumed to predate parental separation, especially parental alcoholism, requiring cautious interpretation of AA survival-analytic findings. CONCLUSION For offspring of European ancestry, parental separation predicts early substance involvement that is not explained by parental alcoholism nor associated family background characteristics. Additional research is needed to better characterize risks associated with parental separation in African American families.

Alcohol use severity and depressive symptoms among late adolescent Hispanics: testing associations of acculturation and enculturation in a bicultural transaction model

Research has indicated that Hispanics have high rates of heavy drinking and depressive symptoms during late adolescence. The purpose of this study was to test a bicultural transaction model composed of two enthnocultural orientations (acculturation and enculturation); and stressful cultural transactions with both the U.S. culture (perceived ethnic discrimination) and Hispanic culture (perceived intragroup marginalization) to predict alcohol use severity and depressive symptoms among a sample of 129 (men=39, women=90) late adolescent Hispanics (ages 18-21) enrolled in college. Results from a path analysis indicated that the model accounted for 18.2% of the variance in alcohol use severity and 24.3% of the variance in depressive symptoms. None of the acculturation or enculturation domains had statistically significant direct effects with alcohol use severity or depressive symptoms. However, higher reports of ethnic discrimination were associated with higher reports of alcohol use severity and depressive symptoms. Similarly, higher reports of intragroup marginalization were associated with higher depressive symptoms. Further, both ethnic discrimination and intragroup marginalization functioned as mediators of multiple domains of acculturation and enculturation. These findings highlight the need to consider the indirect effects of enthnocultural orientations in relation to health-related outcomes.

Gender roles and binge drinking among Latino emerging adults: A latent class regression analysis

Gender roles are often cited as a culturally specific predictor of drinking among Latino populations. This study used latent class regression to test the relationships between gender roles and binge drinking in a sample of Latino emerging adults. Participants were Latino emerging adults who participated in Wave III of the National Longitudinal Study of Adolescent Health (N = 2,442). A subsample of these participants (n = 660) completed the Bem Sex Role Inventory--Short. We conducted latent class regression using 3 dimensions of gender roles (femininity, social masculinity, and personal masculinity) to predict binge drinking. Results indicated a 3-class solution. In Class 1, the protective personal masculinity class, personal masculinity (e.g., being a leader, defending ones own beliefs) was associated with a reduction in the odds of binge drinking. In Class 2, the nonsignificant class, gender roles were not related to binge drinking. In Class 3, the mixed masculinity class, personal masculinity was associated with a reduction in the odds of binge drinking, whereas social masculinity (e.g., forceful, dominant) was associated with an increase in the odds of binge drinking. Post hoc analyses found that females, those born outside the United States, and those with greater English language usage were at greater odds of being in Class 1 (vs. Class 2). Males, those born outside the United States, and those with greater Spanish language usage were at greater odds of being in Class 3 (vs. Class 2). Directions for future research and implications for practice with Latino emerging adults are discussed.

Alcohol Use Severity Among Hispanic Emerging Adults in Higher Education: Understanding the Effect of Cultural Congruity

Background: Identifying and understanding determinants of alcohol use behavior among Hispanic college students is an increasingly important public health issue, particularly during emerging adulthood. Studies examining ethnocultural determinants of alcohol use behavior among Hispanic college students have focused on direct associations with cultural orientation (e.g., acculturation and enculturation); yet there is a need for research that accounts for the complex interplay of other culturally relevant sociocultural factors. Objectives: This study examined associations of behavioral acculturation, behavioral enculturation, and cultural congruity (perception of cultural fit between the values of the academic environment and the students personal values) with alcohol use severity (AUS); and tested if gender moderated those associations. Methods: A hierarchical linear regression and moderation analysis were conducted on a sample of 167 Hispanic emerging adults (ages 18–25) enrolled in college. Results: All predictor variables entered in the regression model accounted for 20.9% of the variance in AUS. After controlling for demographic variables and depressive symptoms, behavioral acculturation and enculturation did not have a statistically significant association with AUS. Further, gender did not moderate either of these associations. Conversely, greater cultural congruity was associated with lower reports of AUS. A moderation analysis suggested that cultural congruity predicted lower reports of AUS among men, but not among women. Conclusions: This was the first known study to examine the association of cultural congruity with alcohol use. Findings highlight the value of examining contextual factors of culture and moving beyond reductive measures of cultural orientation.

Gender Differences in Risk and Protective Factors for Alcohol Use and Substance Use Problems among Hispanic Adolescents

This study investigates gender differences within the context of risk and protective factors for alcohol use and substance use problems in a sample of 8,992 Hispanic students in grades 6 through 12, who responded to a statewide survey of alcohol and other drug use. The effects of gender, grade, and risk and protective factors on past-month alcohol use, binge drinking, and risk for substance use problems are examined. Results show that outcomes were moderated by gender, such that females had greater predicted probabilities than males for alcohol use, binge drinking, and risk for substance use problems across levels of risk and protective factors. An ecological framework is applied to speculate why Hispanic female adolescents were more vulnerable than their males to problem alcohol use.

Public religiosity, religious importance, and substance use among Latino emerging adults

Objective: This study examined the relationship between religiosity (religious importance and public religion) and substance use (binge drinking and marijuana use) among Latino emerging adults. Method: Study utilized data (N = 2,442; 51.9% male) from wave 3 of the National Longitudinal Study of Adolescent Health (Add Health). Results: Only public religion was found to be a protective factor for both binge drinking and marijuana use. Conclusion: The study results suggest the potential for public forms of religion, such as attendance to services and activities, to act as a protective factor for substance use.

Mental Health Problems, Legal Involvement, and Smoking During Pregnancy

The current study examined predictors of past 30-day cigarette use among a US nationally representative sample of pregnant women over the age of 18 (N = 1,782). The study consisted of secondary data analysis of the 2005–2007 survey years of the National Survey on Drug Use and Health (NSDUH). Logistic regression analyses indicated that low-income women, those who experienced mental health problems in the past year, and women who experienced legal problems were more likely to smoke during pregnancy. Limitations to the study as well as implications for future research are discussed.

Childhood family characteristics and prescription drug misuse in a national sample of Latino adults.

Prescription drug misuse is a growing public health concern and has been understudied in Latino populations. The current study tests the relationships between childhood and family characteristics and prescriptions drug misuse among adult Latinos. A subsample of 8,308 Latinos from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were examined. Logistic regression analyses tested associations between parental alcoholism, parental divorce before age 18, and parental death before age 18 and prescription drug misuse and prescription drug use disorder. Parental alcoholism and parental divorce increased the odds of both prescription drug misuse and use disorder. Parental death increased the odds of prescription drug use disorders. The results have important implications for understanding the complex associations between family psychosocial history and prescription drug misuse.
