Young men who have sex with men (YMSM) are among the highest risk groups for HIV, and the risk distribution varies by race/ethnicity. Prevalence rates are consistently higher for minority YMSM. Factors underlying these disparities are poorly understood. We examined disparities in HIV risk among a community-based sample of Black, Latino, and non-Hispanic Caucasian YMSM age 16-24. To address gaps in the literature, we examined factors between and within racial/ethnic groups across domains including: sexual and substance use behaviors, sexualized and other social contexts, psychological well-being, HIV attributes and prevention skills, and sexual minority stress.
