Alcohol Use and Suicidality by Sexual Orientation Among U.S. Youth, 2009-2017.

INTRODUCTION: Alcohol use and suicidality remain serious risks for U.S. youth. Research has established that disparities exist in these outcomes between heterosexual and sexual minority youth. However, research into the associations between alcohol use and suicidality has yet to consider the differential role of sexual orientation. METHODS: Using a pooled, diverse sample from the 2009-2017 Youth Risk Behavior Survey, associations of alcohol use and suicidality by sex and sexual orientation, and changes in these outcomes over time, were investigated. Analyses were conducted in 2019. RESULTS: Suicidality was highest among nonheterosexuals, who ranged from twofold to sevenfold higher odds to report suicidality across all time points, with the most striking disparities among male sexual minority youth. Rates among all students remained stable or increased over time; notable exceptions included a decrease in suicide attempts among bisexual students. Among all students, current alcohol use was associated with elevated levels of suicidality. For female students, the association between drinking and suicidality did not significantly differ by sexual identity; for male students, it was significant regardless of sexual identity and most pronounced among not sure youth. CONCLUSIONS: These results emphasize the need for additional research into the relationship between contemporaneous alcohol use and suicidality, with attention to differences based on sex, sexual orientation, and other factors that may impact these relationships. There is a particular need for research to examine the temporal nature of the association such that evidence-informed, high-impact interventions can be developed to improve suicidality outcomes among sexual minority youth.

Engagement with LGBTQ community moderates the association between victimization and substance use among a cohort of sexual and gender minority individuals assigned female at birth.

BACKGROUND: Research has documented higher levels of substance use among sexual and gender minority (SGM) individuals - particularly sexual minority women (SMW) and transgender people - than among their heterosexual and cisgender peers. Because SGM substance use is linked to stigma-based victimization, it is crucial to identify social contexts that may buffer the association between victimization and substance use among SGM. METHODS: We explored how engagement with LGBTQ-specific community influences victimization experiences and substance use among 488 SGM individuals assigned female at birth (FAB-SGM; ages 16-32; 26% White) in a large Midwestern city. We tested whether participants who used LGBTQ community spaces differed from those who do not in levels of victimization and substance use, and whether use of LGBTQ spaces buffered SGM from the negative effects of victimization on substance use. RESULTS: Results demonstrated significant associations between victimization and alcohol and use of specific drugs. Contrary to expectations, participants who used LGBTQ spaces reported more victimization and more use of certain substances; however, when controlling for being out about non-heterosexual identity, this association remained only for LGBTQ community centers and school groups. Evidence was mixed for community engagement as a moderator of the association between victimization and substance use. CONCLUSIONS: Overall, results indicated that LGBTQ spaces may be associated with adaptive and maladaptive coping functions and should be considered a potential target for health interventions. Findings emphasize the need for increased research on FAB-SGM, including SMW and transgender individuals, and provide actionable recommendations to reduce incidence of victimization and substance use.
