Sexual identity is associated with tobacco use in adults. We examined tobacco
use and susceptibility to use by sexual identity in adolescents. Data were
collected in February 2019 via Qualtrics research participant panels. Data
analyses were performed in June 2019 and updated in October 2020. Respondents
aged 13-17 reported sexual identity (heterosexual vs. sexual minority [lesbian,
gay, bisexual, or other]), past-month and lifetime tobacco product use,
susceptibility to e-cigarette use, friend(s)' e-cigarette use, tobacco
marketing exposure, and demographic characteristics. The sample (n=983) was
72.9% female, 46.5% non-Hispanic white, and 26.1% sexual minority with a mean
age of 15.0 years (SD=1.4). Sexual minority adolescents were more likely to
have friend(s) who vape (53.0% versus 42.0%; p=0.003). In adjusted models,
sexual minority adolescents had greater odds of ever smoking tobacco (odds
ratio [OR]=2.06; 95% confidence interval [CI]: 1.42-2.98) or using e-cigarettes
(OR=1.55; 95% CI: 1.08-2.25) relative to heterosexual adolescents. Past-month
tobacco smoking and e-cigarette use did not differ by sexual identity. Among
participants who had never used tobacco products, sexual minority adolescents
reported greater susceptibility to e-cigarette use (OR=1.62; 95% CI: 1.04-2.52)
compared to heterosexual adolescents. Exposure to cigarette and e-cigarette
marketing, e-cigarette use by friends, and respondent sex were significant
covariates in all models. The current findings indicate greater susceptibility
to use e-cigarettes and greater tobacco product initiation, but not
continuation, among sexual minority adolescents. Sexual minority-tailored
interventions may be warranted to prevent tobacco product initiation. Worth
exploring are the associations between sexual identity, tobacco marketing
exposure, and friend(s)' e-cigarette use.
