	Abstract

Objectives. We used data from a nationally representative sample to examine the associations among 3 dimensions of sexual orientation (identity, attraction, and behavior), lifetime and past-year mood and anxiety disorders, and sex.

Methods. We analyzed data from wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions.

Results. Mental health outcomes differed by sex, dimension of sexual orientation, and sexual minority group. Whereas a lesbian, gay, or bisexual identity was associated with higher odds of any mood or anxiety disorder for both male and female participants, females reporting only same-sex sexual partners in their lifetime had the lowest rates of most disorders. Higher odds of any lifetime mood or anxiety disorder were more consistent and pronounced among sexual minority males than among sexual minority females. Finally, bisexual behavior conferred the highest odds of any mood or anxiety disorder for both males and females.

Conclusions. Findings point to mental health disparities among some, but not all, sexual minority groups and emphasize the importance of including multiple measures of sexual orientation in population-based health studies.
