Background: No national studies have explored the role of psychosocial factors to explain differences in tobacco use across sexual orientation groups in adolescents. Methods: Survey data from 12,224 adolescent girls and boys participating in 1999 in the Growing Up Today Study, a national longitudinal cohort study, were examined cross-sectionally using univariate descriptive statistics and multivariate regression analyses. Results: 92% of subjects described themselves as heterosexual (n=9,296), 6% as mostly heterosexual (n=511), 1% as gay/bisexual (n=103), 2% as unsure (n=226). Subjects were 12 to 17 years old. Gay/bisexuals and mostly heterosexuals reported greater tobacco use than heterosexuals, even when controlling for age, pubertal stage, depressive symptoms, self-esteem, BMI, and region of residence in multivariate models. Gay/bisexual girls were 6.6 (95% CI: 3.6, 12.4) times more likely and mostly heterosexual girls were 2.3 (95% CI: 1.8, 2.9) times more likely than heterosexual girls to have ever smoked. Among girls who reported smoking in the past year, gay/bisexual girls had 4.2 times (95% CI=1.6, 10.8) the odds of smoking weekly compared to heterosexual girls, and gay/bisexual girls and mostly heterosexual girls were more highly addicted to tobacco (p<.05). Gay/bisexual boys were 2.1 (95% CI: 1.1, 4.3) times more likely and mostly heterosexual boys were 2.0 (95% CI: 1.3, 3.0) times more likely than heterosexual boys to have ever smoked. Conclusions: These results indicate that sexual orientation group differences in tobacco use and addiction persist even when accounting for effects of multiple factors previously thought to explain differences in tobacco use.
