The overall goal of the RADAR study is to identify and understand the connections among sexually transmitted infections (like HIV), drug and alcohol use, and romantic or sexual relationship patterns over time among young men who have sex with men (YMSM). This cooperative agreement with the National Institute on Drug Abuse marks the first time that one study will look at drivers of new HIV infections at multiple levels- the genetics of the virus, effects of medications, individual behavior, sexual partner and relationship characteristics, networks, and community-level factors.
Age range: 16-29+
HIV status: negative (~80%), positive (~20%)
Race and ethnicity: All. Approx. 34% African American, 30% Hispanic, and 24% White/Caucasian.
