Abstract:
PurposeTo identify key social and structural factors associated with hazardous alcohol and problematic drug use among sexual and gender minority (SGM) adults.MethodsWe conducted a cross-sectional secondary analysis of 2016 to 2019 data from the Generations Study, a probability sample of 1518 SGM adults. Hazardous alcohol and problematic drug use were measured using the Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) and Drug Use Disorder Identification Test (DUDIT). Candidate predictors included sociodemographic characteristics, minority stressors, adverse childhood experiences, health indicators, and social support. Interpretable machine-learning models with SHapley Additive exPlanations characterized multilevel correlates of 3-level risk categories.ResultsHazardous alcohol use was linked to past smoking, lower social support, cancer history, housing instability, and identity-related stressors. Problematic drug use was linked to conversion-therapy exposure, housing discrimination, legal encounters, and mental-health indicators; prediction was more accurate for drug- than alcohol-use risk.ConclusionStructural vulnerability, discrimination, and identity-related stressors emerged as intervention targets to reduce substance-use disparities in SGM adults.
