Intersectionality of Sexual Orientation With Race and Ethnicity and Associations With E-Cigarette Use Status Among U.S. Youth

Introduction: Although structural discrimination against sexual and racial/ethnicity minorities is a putative risk factor for youth tobacco use, understanding health disparities in youth E-cigarette use at the intersection of sexual orientation, race, and ethnicity is still lacking. This study aims to examine the differences in E-cigarette use prevalence among U.S. youth at the intersections of sexual orientation with race and ethnicity.

Methods: E-cigarette use status (never, experimental, or current use) was analyzed among 38,510 U.S. youth using a pooled data set from the Youth Risk Behavior Surveillance System 2015-2019. The weighted E-cigarette use status between youth at the intersections of sexual orientation with race and ethnicity was reported, stratified by sex. Multivariable multinomial regression adjusting for relevant covariates was further conducted. Data analyses were performed in April 2022.

Results: After controlling for other covariates, the RRR of current E-cigarette use compared with never use between lesbian Black girls (and heterosexual Black girls) was higher than between lesbian White girls (and heterosexual White girls) (adjusted RRR=6.99; 95% CI=2.21, 22.14). The RRR of current E-cigarette use compared with never use between lesbian other race/multiracial girls (and heterosexual other race/multi-racial girls) was higher than between lesbian White girls (and heterosexual White girls) (adjusted RRR=3.60; 95% CI=1.06, 12.26).

Conclusions: This study has shown that sexual minority Black girls were more likely to currently use E-cigarettes than heterosexual Black girls. Future studies should examine the underlying reasons for current E-cigarette use among girls with intersectional identities, including race and sexual orientation.
