Health Disparities Among Exclusively Lesbian, Mostly Lesbian, and Bisexual Young Women

Abstract

Purpose: Health disparities have been identified between groups of diverse young sexual minority women (SMW) and heterosexual women. This approach may generate sufficient group sizes for statistical analyses but obscures important differences. Moreover, some young women may not identify as "lesbian" or "bisexual" but somewhere in between. This study examined health and sexual minority identity-specific outcomes among three groups of SMW-women who identify as "exclusively lesbian," "mostly lesbian," and "bisexual." Methods: Participants were 990 young (18-30 years old) SMW (exclusively lesbian: n = 305, mostly lesbian: n = 133, bisexual: n = 552) who completed an online survey, including information about mental and physical health symptoms, hazardous drinking, and identity uncertainty. Those who reported alcohol use in the past 30 days responded to questions about their alcohol use and alcohol-related negative consequences. Results: Controlling for demographic differences, health outcomes varied significantly by identity. Mostly lesbian and bisexual women reported the most depression, anxiety, and physical health symptoms; mostly lesbian women reported the highest levels of hazardous drinking. Among those who reported drinking, mostly lesbian women drank the most frequently and reported the most alcohol-related consequences. Mostly lesbian women reported the most identity uncertainty. Conclusion: Mostly lesbian women were similar to bisexual women on several health outcomes. They appear unique, however, in drinking behavior and identity uncertainty. Collapsing across identities in health research may affect outcomes.
