Background: In the United States, Latino men who have sex with men (MSM) are disproportionately affected by HIV. However, little is understood about variations in HIV risk by location of birth and time since immigration for foreign-born MSM. We assessed differences in HIV prevalence among Latino MSM by these characteristics.
Methods: For the National HIV Behavioral Surveillance System (NHBS) among MSM, venue-based sampling was used to recruit men. In 20 cities in the continental United States, men were interviewed and tested for HIV infection. We analyzed data for Latino men who reported ≥1 male sex partner in the past 12 months. We compared HIV prevalence for three groups (U.S.-born, foreign-born who immigrated ≤5y ago, and foreign-born who immigrated >5y ago). We used generalized estimating equations (clustered on city of interview) to identify factors associated with prevalent HIV infection. We also determined the proportion unaware of their infection (those who tested positive but reported a negative or unknown HIV status during the interview).
Results: We interviewed and tested 1734 Latino MSM. HIV prevalence was highest among foreign-born MSM who immigrated >5y ago (see table). Among HIV-positive Latino MSM, 43% were unaware of their infection; this did not vary by location of birth or time since immigration. In multivariate analysis including age and income, HIV infection was more prevalent among foreign-born MSM who immigrated >5y ago and U.S.-born Latino MSM, both compared with persons who were foriegn-born and immigrated ≤5y ago. HIV prevalence was also associated with increasing age and income < $20,000.
Conclusions: Lower HIV prevalence among foreign-born Latino MSM shortly after immigration contrasts with higher HIV prevalence among foreign-born Latino MSM >5 years after immigration and suggests a critical window of opportunity for HIV prevention. Prevention activities among Latino MSM should prioritize those with low income, who are at particular risk for HIV infection.
