Multilevel Influences on HIV and Substance Use in a YMSM Cohort (RADAR)
The RADAR study is designed to provide insights into risk and protective factors for HIV and drug use among young men who have sex with men and transgender women (YMSM). Participants include over 1,000 male individuals, recruited from two previous research projects, Project Q2 and Crew 450, alongside a third cohort of newly recruited individuals and their romantic partners. Those from the previous research projects and newly recruited participants were aged 16 to 20 years old, while their romantic partners could be up to 29 years old. Since the beginning of the study in 2015, participants have been followed up over 15 times, with follow-ups occurring every 6 months.
