Background: The objectives were to assess the impact of HIV on young Latino MSM on each side of the U.S.-Mexico border at San Diego and Tijuana and to estimate and compare their lifetime and recent risk behaviors.
Methods: From May 2000 to December 2001, 374 young Latino MSM aged 18 to 29 years were recruited from cruising areas/parks, gay bars/clubs, and other gay-identified venues in San Diego and Tijuana. Risk behavior was ascertained by interviewing participants from a standardized questionnaire. A blood sample was then collected and tested for HIV antibodies.
Results: HIV seroprevalence was 20.5% in the Tijuana sample (n=249) and 35.2% in the San Diego sample (n=125). Tijuana MSM were more likely than San Diego MSM (p<0.01) to report a lifetime history of having over 10 female sex partners (35.3% vs 6.4%), ever having unprotected vaginal sex (77.5% vs 36.8%), and ever having unprotected anal sex with a female (43.0% vs 13.6%). San Diego MSM were more likely than Tijuana MSM (p<0.01) to report more than 10 lifetime male sex partners (60.0% vs 26.9%) and ever having receptive unprotected anal intercourse (76.0% vs 28.1%). Over 45% of Tijuana MSM and over 75% of San Diego MSM reported sex with a male from across the border. Tijuana MSM reported more injection drug use than San Diego MSM. Over 41% of the Tijuana sample reported ever injecting and over 37% ever sharing needles/works, compared to 7.2% and 4.8%, respectively, for San Diego MSM (p<0.01).
Conclusions: Our data indicate that young Latino MSM in Tijuana are more likely to engage in more risky sexual behavior with women and injection drug use behavior than San Diego MSM. Young Latino MSM in San Diego are more likely to engage in more risky sexual behavior with male sex partners than Tijuana MSM. Binational collaboration is needed to develop and provide enhanced behavioral interventions for young Latino MSM.
