Crew 450 is an ongoing longitudinal cohort study of young men who have sex with men (YMSM) aged 16 – 20 being conducted in the Chicagoland area. This research study was designed to analyze the prevalence, course, and predictors of a syndemic of psychosocial health issues linked to HIV among YMSM. In addition, Crew 450 strives to learn more about the factors related to causes and grouping of health problems such as substance abuse, experience of violence, and mental health in this population.
The two main goals of this study are:
- To provide much-needed epidemiologic data on the prevalence of HIV and related health issues among YMSM in order to inform public health priorities.
- To collect vital information on risk and protective factors to inform the development of an intervention targeting this vulnerable population.
The study has successfully recruited a final sample of 451 YMSM and is actively collecting data at follow-up assessments. Crew 450 is being conducted in collaboration with the Center for Sexuality, Gender, and HIV Prevention at Ann & Robert H. Lurie Children’s Hospital of Chicago.
