Note. SO = sexual orientation; AOR = adjusted odds ratio; CI = confidence interval. Model 1 shows the estimated odds of substance use by each dimension of SO considered singly. Model 2 shows the estimated odds of substance use by each dimension of SO while controlling for the other 2 dimensions. All AORs adjusted for respondent's age, age squared, race/ethnicity, and design effects. AORs in model 2 for each outcome also adjusted for behavior, attraction, and identity.
Differs from reference category at P < .05.
Differs from gay/bisexual at P < .05.
Differs from those with exclusively same-gender partners at P < .05.
Differs from those with partners of both genders at P < .05.
Differs from those reporting at least some same-gender attraction at P < .05
