Intersectional Disparities in Youth Tobacco Use by Sexual and/or Gender Minority Status and Race and/or Ethnicity

Introduction: The current study applied an intersectional lens to examine societal factors, individual psychological outcomes, and youth combustible tobacco and vape use at the intersection of sexual and/or gender minority (SGM) status and race and/or ethnicity. Aims and Methods: Data were drawn from 133 969 youth respondents surveyed in the 2019-2020 California Student Tobacco Survey, a representative school-based survey of 8th and 10th(-)grade public school students throughout California. The impact of multiple marginalized group membership using four mutually exclusive intersectional positions (non-SGM white, SGM white, racial minority only, and both SGM and racial minority), in addition to specific differences across ten SGM by race and/or ethnicity groups (e.g. non-SGM black or African American, SGM black or African American, etc.) were assessed. Results: Compared to heterosexual and cisgender white youth, SGM and racial minority adolescents were shown to experience poorer school tobacco education quality and cessation support, lower school and family connectedness, and higher anxiety and depression symptoms. SGM and racial minority youth had a higher prevalence of ever-combustible tobacco use but were less likely to be current vape users compared to non-SGM white respondents. In examining specific group differences, results revealed that SGM teens had the highest risk of ever combustible tobacco use. This disparity was amplified for those belonging to multiple marginalized groups, with black or AA SGM teens evidenced to be at the highest risk of current combustible tobacco. Conclusions: Information from this study has useful implications for SGM measurement in surveillance systems and highlights the usefulness of adopting an intersectional approach to inform equity-driven public health policy and intervention. Implications: This representative study of California youth supports that identifying as a sexual and/or gender minority (SGM) is an important risk factor for combustible tobacco use. Particularly, observed SGM disparities were magnified for the youth belonging to marginalized groups, as black or African American SGM teens were shown to be at the highest risk of current combustible tobacco use. Findings support that Intersectionality Theory represents a useful framework for examining tobacco-related disparities and underscores the importance of assessing how the intersection of multiple social categories impacts youth tobacco use.
