Understanding pathways to e-cigarette use across sexual identity: A multi-group structural equation model

This study explored the relationships between sexual violence, smoking behaviors, suicidality and past 30-day e-cigarette use under the theoretical framework of Minority Stress Theory. The 2017 National Youth Risk Behavioral Survey was utilized to study a nationally representative sample of sexual minority (lesbian, gay, bisexual, and unsure) and heterosexual high school students (N = 7882). Multi-group structural equation modeling (SEM) was employed to examine whether sexual violence and suicidality had a direct effect on e-cigarette use, after controlling for prior smoking behaviors (cigarette, cigar, and marijuana use). Suicidality and smoking behaviors were examined as mediators of the relationship between sexual violence and e-cigarette use, and suicidality was examined as a mediator of the relationship between sexual violence and smoking behaviors. This model was tested for invariance across sexual minority and heterosexual students. For both groups, smoking behaviors had significant direct effects on e-cigarette use, yet suicidality revealed no significant direct effects. Both suicidality and sexual violence had significant indirect effects on e-cigarette use through their effects on smoking behaviors. Sexual violence had a significant direct effect on e-cigarette use for sexual minority students, but not for heterosexual students. Despite this notable difference, the model was found to be invariant across the two groups. These findings suggest that students who report sexual violence may experience suicidality and victimization may lead to smoking behaviors and e-cigarette use. Students' mental health and substance use behaviors should continue to be targeted in schools, particularly among sexual minority youths.

A supportive school environment may reduce the risk of non-medical prescription opioid use due to impaired mental health among students

Canada is in the midst of an ongoing, escalating opioid crisis, with significant impacts on adolescents and young adults. Accordingly, mental health impairment was examined as a risk factor for non-medical prescription opioid use (NMPOU) among high school students. In addition, the moderating effects of the school environment, in terms of the availability of mental health services and substance use policies, were characterized. Self-reported, cross-sectional data were obtained from the COMPASS study, including 61,239 students (grades 9-12) in 121 secondary schools across Canada. Current and lifetime NMPOU were ascertained. Categorical indicators of mental health impairment and school environment were derived. The main analytical strategy encompassed hierarchal multilevel logistic regression, including the addition of interaction terms to characterize the moderation effects. Current and lifetime NMPOU were reported by 5.8% and 7.2% of the students, respectively. After adjusting for confounders, students in the highest quintile of mental health impairment had odds ratios (OR) of 2.60 (95% confidence interval [CI] 2.29-2.95) and 2.96 (95% CI 2.64-3.33) for current and lifetime NMPOU, respectively when compared to students in the lowest quintile of mental health impairment. A significant interaction between mental health impairment and school environment indicated relatively lower risks of NMPOU in students from schools that provide more mental health services and have stricter substance use policies. Mental health impairment increased the risk of NMPOU, but the associations were moderated by the school environment. These findings underscore the importance of mental health services and substance use regulations in schools.

Is substance abuse treatment actually 'treating'? The effectiveness of pre- and post-release substance abuse programming within the reentry process

The process of reintegrating back into society can be a difficult time for formerly incarcerated individuals in desisting from substance use. Although prior work has shown that experiences like securing employment or abstaining from criminal peers can help individuals desist from substance use, one aspect about which criminologists know considerably less concerns the role of substance abuse treatment programming during reentry. Using the Serious and Violent Offender Reentry Initiative data, we explore the role of substance treatment programming on substance use through multiple avenues. Namely, we investigate the impact of substance abuse treatment during prison, during reentry, and over time. Results of longitudinal models demonstrate that individuals who participated in pre-release substance abuse treatment programming report significantly lower levels of substance use than those who did not participate in pre-release substance programming. Yet, we find that individuals who participated in substance treatment programming post-release reported significantly higher levels of substance use than those who did not participate in post-release programming. Finally, we find no evidence that substance use treatment programming relates to decreases in substance use across time.

Tobacco harm perceptions and use among sexual and gender minorities: findings from a national sample of young adults in the United States

INTRODUCTION

In the United States, the prevalence of tobacco use among sexual and gender minorities (SGM) is higher compared to their non-SGM counterparts. Tobacco harm perceptions have gone largely unexamined as a potential mechanism supporting disproportionate tobacco use among this population. The purpose of this study was to examine differences between SGM and non-SGM young adults in harm perceptions of various tobacco products and tobacco use behavior and whether low tobacco-related harm perceptions moderate the relationship between identifying as a SGM and tobacco use behavior.

METHODS

This study used data from Wave 10 of the Truth Initiative Young Adult Cohort Study, a sample of U.S. young adults (ages 18-34). Data were collected from September to October 2016 and the study sample included 3089 individuals. Demographics, past 30-day use of cigarettes, little cigars/cigarillos/bidis and electronic cigarettes were assessed. Absolute and relative harm perceptions of these products were also examined.

RESULTS

Identifying as a SGM and low tobacco harm perceptions were found to be positively associated with past 30-day tobacco use. There was no interaction between SGM status and harm perceptions on past 30-day tobacco use CONCLUSIONS: Findings confirm that SGM young adults continue to disproportionately use tobacco products, compared to non-SGM young adults. More research is needed to understand moderators of the relationship between SGM status and tobacco use in young adults.

Cost-effective way to reduce stimulant-abuse among gay/bisexual men and transgender women: a randomized clinical trial with a cost comparison

OBJECTIVES

A randomized controlled study was conducted with 422 homeless, stimulant-using gay/bisexual (G/B) men and 29 transgender women (n = 451) to assess two community-based interventions to reduce substance abuse and improve health: (a) a nurse case-managed program combined with contingency management (NCM + CM) versus (b) standard education plus contingency management (SE + CM).

STUDY DESIGN

Hypotheses tested included: a) completion of hepatitis A/B vaccination series; b) reduction in stimulant use; and c) reduction in number of sexual partners.

METHODS

A deconstructive cost analysis approach was utilized to capture direct costs associated with the delivery of both interventions. Based on an analysis of activity logs and staff interviews, specific activities and the time required to complete each were analyzed as follows: a) NCM + CM only; b) SE + CM only; c) time to administer/record vaccines; and d) time to receive and record CM visits. Cost comparison of the interventions included only staffing costs and direct cash expenditures.

RESULTS

The study outcomes showed significant over time reductions in all measures of drug use and multiple sex partners, compared to baseline, although no significant between-group differences were detected. Cost analysis favored the simpler SE + CM intervention over the more labor-intensive NCM + CM approach. Because of the high levels of staffing required for the NCM relative to SE, costs associated with it were significantly higher.

CONCLUSIONS

Findings suggest that while both intervention strategies were equally effective in achieving desired health outcomes, the brief SE + CM appeared less expensive to deliver.
