Sexual-orientation differences in alcohol use trajectories and disorders in emerging adulthood: results from a longitudinal cohort study in the United States.

ABSTRACT: AIMS:We estimated sexual-orientation differences in alcohol use trajectories during emerging adulthood, and tested whether alcohol use trajectories mediated sexual-orientation differences in alcohol use disorders (AUDs). DESIGN:Longitudinal self-reported survey data from the Growing Up Today Study. SETTING:United States. PARTICIPANTS:A total of 12?493 participants aged 18-25 during the 2003, 2005, 2007 or 2010 surveys. MEASUREMENTS:Stratified by gender, longitudinal latent class analyses estimated alcohol use trajectories (using past-year frequency, quantity and binge drinking from 2003 to 2010). Multinomial logistic regression tested differences in trajectory class memberships by sexual orientation [comparing completely heterosexual (CH) participants with sexual-minority subgroups: mainly heterosexual (MH), bisexual (BI) and gay/lesbian (GL) participants]. Modified Poisson regression and mediation analyses tested whether trajectories explained sexual-orientation differences in AUDs (past-year DSM-IV abuse/dependence in 2010). FINDINGS:Six alcohol use trajectory classes emerged for women and five for men: these included heavy (23.5/36.9% of women/men), moderate (31.8/26.4% of women/men), escalation to moderately heavy (9.7/12.0% of women/men), light (17.0% for women only), legal (drinking onset at age 21; 11.1/15.7% of women/men) and non-drinkers (7.0/9.1% of women/men). Compared with CH women, MH and BI women had higher odds of being heavy, moderate, escalation to moderately heavy and light drinkers versus non-drinkers (odds ratios = 2.02-3.42; P-values < 0.01-0.04). Compared with CH men, MH men had higher odds of being heavy, moderate and legal drinkers versus non-drinkers (odds ratios = 2.24-3.34; P-values < 0.01-0.01). MH men and women, BI women and GLs had higher risk of AUDs in 2010 than their same-gender CH counterparts (risk ratios = 1.34-2.17; P-values < 0.01). Alcohol use trajectories mediated sexual-orientation differences in AUDs for MH and GL women (proportion of effect mediated = 30.8-31.1%; P-values < 0.01-0.02), but not for men. CONCLUSIONS:In the United States, throughout emerging adulthood, several sexual-minority subgroups appear to have higher odds of belonging to heavier alcohol use trajectories than completely heterosexuals. These differences partially explained the higher risk of alcohol use disorders among mainly heterosexual and gay/lesbian women but not among sexual-minority men.

Project description:ImportanceSexual minority men have reported higher rates of both indoor tanning and skin cancer than heterosexual men, and sexual minority women have reported lower or equal rates of both indoor tanning and skin cancer compared with heterosexual women. Bisexual men, in particular, have reported higher rates of indoor tanning bed use than heterosexual men; however, no study has investigated skin cancer prevalence among gay, lesbian, and bisexual individuals as separate groups.ObjectiveTo evaluate the association between sexual orientation and lifetime prevalence of skin cancer.Design, setting, and participantsThis cross-sectional study analyzed data from the 2014-2018 Behavioral Risk Factor Surveillance System (BRFSS) surveys of a noninstitutionalized population in the United States that included 877 650 adult participants who self-identified as being heterosexual, gay, lesbian, or bisexual.Main outcomes and measuresSelf-reported lifetime history of skin cancer.ResultsThe study included 877 650 participants, including 364 833 heterosexual men (mean age, 47.7; 95% CI, 47.5-47.8), 7823 gay men (mean age, 42.7; 95% CI, 41.8-43.6), 5277 bisexual men (mean age, 39.4; 95% CI, 38.4-40.5), 484 341 heterosexual women (mean age, 49.7; 95% CI, 49.6-49.8), 5609 lesbian women (mean age, 41.8; 95% CI, 40.6-43.0), and 9767 bisexual women (mean age, 32.8; 95% CI, 32.3-33.3). The adjusted odds ratios (AORs) of skin cancer prevalence were significantly higher among both gay (AOR, 1.25; 95% CI, 1.03-1.50; P = .02) and bisexual men (AOR, 1.46; 95% CI, 1.01-2.10; P = .04) compared with heterosexual men. The AORs of skin cancer were statistically significantly lower among bisexual women (AOR, 0.75; 95% CI, 0.60-0.95; P = .02) but not among gay or lesbian women (AOR, 1.01; 95% CI, 0.77-1.33; P = .95) compared with the AORs of skin cancer among heterosexual women.Conclusions and relevanceIn this study, gay and bisexual men had an increased self-reported lifetime prevalence of skin cancer compared with the prevalence among heterosexual men. Patient education and community outreach initiatives focused on reducing skin cancer risk behaviors among gay and bisexual men may help reduce the lifetime development of skin cancer in this population. Continued implementation of the Behavioral Risk Factor Surveillance System's sexual orientation and gender identity module is imperative to improve understanding of the health and well-being of sexual minority populations.
