Recruiting substance-using men who have sex with men into HIV prevention research: current status and future directions.

Research investigators have identified increasing challenges to the recruitment of men who have sex with men (MSM) for observational and intervention HIV/AIDS studies. To address these issues, program staff from the National Institute on Drug Abuse convened a meeting on April 28th to 29th, 2009 to discuss issues in MSM recruitment. The panel indicated that there was decreased community identification with HIV research, although altruistic, community-oriented motives continued to be important. Substance use adds to recruitment challenges, particularly recruitment of MSM who use stigmatized substances. Relatively new recruitment methods such as respondent driven sampling, venue-data-time sampling, and internet sampling have helped advance knowledge about the recruitment process; however, they have not mitigated the challenges to MSM recruitment. Recruitment of youth and members of racial/ethnic minority populations present additional considerations. This report summarizes the meeting's proceedings, key points of discussion, and areas for further research consideration.
