Participant Demographics
RADAR is the largest longitudinal study of YMSM ever conducted and is unique in its focus of this young risk group, its diversity (33.7% Black, 29.9% Latino/Hispanic, 25.5% White, 7.6% multi-racial, 2.4% Asian, < 1% Other, Pacific Islander/Native American/Native Alaskan).
This mirrors the demographics of the city of Chicago, which is also the urban epicenter of HIV and drug epidemics in the Midwest (Cook County, IL, where Chicago is located, was fourth in HIV incidence in 2017).
Geographic Reach and Study Milestones
- Study participants reside in over 40 US states and 6 countries.
- RADAR has provided over 6,000 HIV tests to study participants.
- RADAR was the first major study to enroll dyads into a YMSM cohort.
- RADAR has successfully retained cohort participants who are living with HIV and who are HIV-negative (>80%).
- RADAR researchers publish scientific outputs frequently (40+ publications).
- RADAR created an innovative research platform (25+ connected studies; 7 concepts via NIDA C3PNO consortium).
Research Aims
- Keep a pulse on emerging trends in drug use, HIV risk/preventive behaviors, and care continuum engagement
- Continue to enroll cohort members’ new serious partners
- Build on our provocative findings of high levels of systematic inflammation in the RADAR cohort regardless of HIV status
- Continue to add specimens and data to our well-characterized biobehavioral respository to provide a platform for high-impact science
A Community-Embedded Study
The Institute for Sexual and Gender Minority Health and Wellbeing (ISGMH) is the resident research partner of Center on Halsted—the Midwest’s largest and most comprehensive LGBTQ community center. Center on Halsted offers a vast array of services and programs, including a comprehensive HIV testing and linkage-to-care program, mental health services, and domestic violence prevention programs. RADAR study visits take place at Center on Halsted in a private research space, which provides a welcoming environment for diverse YMSM from across Chicago, allows for us to make warm handoffs to services needed by participants, and allows for rapid community dissemination of study findings.
The RADAR Community Advisory Board (CAB)
The RADAR CAB is comprised of health professionals from local organizations serving YMSM, as well as adolescent and young adults from the community. Our CAB discuss new aspects of the RADAR project, study findings, and community information needs. The CAB meets on a bi-annual basis and is also regularly accessed for ad hoc consultation.
