Intersectional Minority Stress and Alcohol, Tobacco, and Cannabis Use Among Sexual and Gender Minority Adolescents of Color: Moderating Role of Family Support.

Purpose: We examined the associations between intersectional minority stress and substance use among sexual and gender minority (SGM) adolescents of color and the moderating role of family support on these associations.

Methods

Data were from a national U.S. sample of SGM adolescents of color (N = 3423). Intersectional minority stress was assessed with the LGBT People of Color Microaggressions Scale.

Results

Intersectional minority stress was associated with greater odds of recent and heavy alcohol and recent cannabis use, but not tobacco use. When examining specific domains of intersectional minority stress, racism from SGM communities was associated with greater odds of recent and heavy alcohol, and recent cannabis use, whereas heterosexism from same racial/ethnic communities was associated with greater odds of recent cigarette and cigar use. Family support was associated with lower substance use. Family support was not a significant moderator.

Conclusions

Findings underscore the need to examine intersectional stressors that SGM adolescents of color experience and to bolster family supports to prevent substance use. Family support did not buffer the effects of intersectional minority stress on substance use outcomes, suggesting that other strategies, such as other forms of family support (e.g., identity-specific support) and community-level and structural changes that target reducing and dismantling oppression are needed to reduce the deleterious impact of intersectional minority stress.
