Oppression-Based Stress and Alcohol Inequities Among Sexual and Gender Minority People: An Intersectional Multilevel Framework.

Purpose: Sexual and gender minority (SGM) people are at heightened risk for alcohol use, hazardous drinking, and alcohol use disorder compared to heterosexual and cisgender individuals. This paper: (a) presents an oppression framework that integrates intersectionality, stress, stigma, and addiction-based theories to examine the complex and nuanced ways oppression-based stress (e.g., minority stress) leads to sexual orientation and gender identity inequities in alcohol use; (b) conducts a narrative review that summarizes recent and novel advancements in the literature on the impact of oppression-based stressors on alcohol use outcomes across structural, interpersonal, and intrapersonal domains among SGM people; and (c) provides future research and intervention directions for the alcohol field.

Search methods: A select review of the literature was conducted on July 10, 2023, using multiple electronic databases (i.e., PsycInfo, PubMed, Web of Science) and focusing on studies that had examined the associations between oppression-based stressors and alcohol use outcomes across structural, interpersonal, and intrapersonal levels. Search terms focused on alcohol consumption; SGM people, particularly SGM people of color; and oppression-based stress. Cross-sectional studies that focused on heterosexism-based and anti-bisexual oppression-based stressors at the interpersonal or intrapersonal levels and alcohol use outcomes were excluded as they have been included in prior reviews of the literature.

Search results: The initial and combined search across the databases resulted in 3,205 articles. Of those, the narrative review included 50 peer-reviewed articles that focused on the following four areas of the literature on the associations between oppression-based stressors and alcohol use outcomes: (1) experimental, longitudinal, and experience sampling studies of heterosexism- and anti-bisexual oppression-based stressors (22 articles); (2) any studies of cissexism-based stressors (12 articles); (3) any studies of intersectional oppression among SGM people of color (seven articles, one article overlapped with the first category and another overlapped with the fourth category); and (4) any studies of structural oppression (11 articles).

Discussion and conclusions: Results of this narrative review indicate that mounting evidence implicates oppression-based stress in inequities in alcohol use, hazardous drinking, and alcohol use disorder in SGM populations. This reflects SGM people's embodiment of oppression and injustice at the structural, interpersonal, and intrapersonal levels. Given some inconsistent and mixed patterns of findings, future research needs greater specificity in drinking inclusion criteria, robust and well-validated measures, more attention to culturally and developmentally relevant moderating and mediating mechanisms across the lifespan, application of sophisticated methodologies, and integration of intersectional and addiction frameworks.
