HIV prevention interventions with gay or bisexual men and youth.

This article describes and reviews the findings of several well-designed and controlled outcome trials of HIV prevention interventions that have been undertaken with men who have sex with men. The interventions reviewed have been of two types: face-to-face group or workshop interventions and community-level programs undertaken in gay communities. Both have shown robust effectiveness in promoting risk reduction behavior change among gay men and young people at risk for contracting HIV infection. Conclusions can now be reached about the benefits of these types of interventions. However, there remains an urgent need to develop and tailor HIV prevention approaches that can promote the maintenance of behavior change; to reach community segments that remain vulnerable, especially young and minority men who have sex with men; and to address the changing context of the epidemic.
