Cannabis use trajectories over time in relation to minority stress and gender among sexual and gender minority people.

Substance use disparities among sexual and gender minority (SGM) people are attributed to minority stress, but few studies have examined minority stress and cannabis use over time or investigated differences in cannabis use trajectories by less-studied gender subgroups. We examined if longitudinal cannabis use trajectories are related to baseline minority stressors and if gender differences persisted after accounting for minority stress. Cannabis use risk was measured annually over four years (2017-2021) within a longitudinal cohort study of SGM adults in the United States (N = 11,813). Discrimination and victimization, internalized stigma, disclosure and concealment, and safety and acceptance comprised minority stress (n = 5,673). Latent class growth curve mixture models identified five cannabis use trajectories: 'low or no risk', 'low moderate risk', 'high moderate risk', 'steep risk increase', and 'highest risk'. Participants who reported past-year discrimination and/or victimization at baseline had greater odds of membership in any cannabis risk category compared to the 'low risk' category (odds ratios [OR] 1.17-1.33). Internalized stigma was related to 'high moderate' and 'highest risk' cannabis use (ORs 1.27-1.38). After accounting for minority stress, compared to cisgender men, gender expansive people and transgender men had higher odds of 'low moderate risk' (ORs 1.61, 1.67) or 'high moderate risk' (ORs 2.09, 1.99), and transgender men had higher odds of 'highest risk' (OR 2.36) cannabis use. This study indicates minority stress is related to prospective cannabis use risk trajectories among SGM people, and transgender men and gender expansive people have greater odds of trajectories reflecting cannabis use risk.

Substance Use Over Time Among Sexual and Gender Minority People: Differences at the Intersection of Sex and Gender.

Purpose: Sexual and gender minority (SGM) people are at greater risk for substance use than heterosexual and cisgender people, but most prior work is limited by cross-sectional analyses or the examination of single substance use. This study examined substance use over time among SGM people to identify patterns of polysubstance use at the intersection of sex and gender. Methods: Data were collected annually over 4 years from SGM respondents (n = 11,822) in The Population Research in Identity and Disparities for Equality (PRIDE) Study. Differences in substance use patterns (any prior 30-day use of 15 substances) by gender subgroup were examined with latent class analysis, and multinomial regression models tested relationships between gender subgroup and substance use. Results: Eight classes of substance use were observed. The three most common patterns were low substance use (49%), heavy episodic alcohol use (≥5 alcoholic drinks on one occasion) with some cannabis and tobacco use (14%), and cannabis use with some tobacco and declining heavy episodic alcohol use (13%). Differences observed included lower odds of patterns defined by heavy episodic alcohol use with some cannabis and tobacco use in all gender subgroups relative to cisgender men and persons with low substance use (odds ratios [ORs] 0.26-0.60). Gender expansive people assigned female at birth, gender expansive people assigned male at birth, and transgender men had greater odds of reporting cannabis use with small percentages of heavy episodic alcohol and tobacco use (ORs: 1.41-1.60). Conclusion: This study suggests that there are unique patterns of polysubstance use over time among gender subgroups of SGM people.

AWARENESS: A cognitive behavioral intervention to reduce intersectional minority stress among sexual minority men living with HIV who use substances.

Introduction: The minority stress model is the primary explanatory model for disparities in substance use and other mental health problems among sexual minority men (SMM) compared to heterosexual men. This pilot randomized controlled trial tested the feasibility of AWARENESS, a novel 9-session cognitive-behavioral psychotherapeutic intervention that targets intersectional minority stress and stigma, among sexual minority men living with HIV who use substances. Methods: Feasibility was determined by the number of participants screened to obtain the target sample size, the percentage of eligible participants randomized, percentage of study intervention and assessment visits attended, time to complete study procedures, and percentage of data completeness of intervention assessments. Forty-two sexual minority men living with HIV with any illicit substance use or who reported at least one occasion of consuming five or more drinks in one setting in the last three months were randomized to AWARENESS (n = 22) or an attention control condition (n = 20). Results: Feasibility of the trial was supported, with adequate completion of study procedures and visits (73% completed all intervention sessions, 71% completed all study assessment sessions). This trial also demonstrated the feasibility of using AWARENESS skills and strategies in relation to multiple intersecting identities, with participants discussing an average of 5.7 identities (e.g., sexual orientation) or individual characteristics (e.g., socioeconomic status) in relation to intervention content. Conclusion: Our results support the feasibility of an AWARENESS trial to reduce intersectional minority stress related to multiple identities and characteristics among sexual minority men living with HIV who use substances.
