Funded at Northwestern University · NIH-11458430 · Data updated 2026-11-12

Researchers will survey 2,700 young men who have sex with men and transgender women across five U.S. cities to learn how social networks, neighborhoods, and access to resources relate to HIV risk and substance use.

Who could benefit from this research

Could help

Young men who have sex with men and transgender women—particularly Black/African American individuals—living in the participating cities and willing to complete remote network surveys are the ideal candidates.

Less likely to help

People who are not MSM or transgender women, who are outside the study cities, or who do not match the study's age or demographic targets likely would not benefit directly from participation.

What this research studies

This project invites people like me—young men who have sex with men and transgender women, especially Black participants—to complete remote surveys about our friendships, places we go, and experiences with stigma and services. The team will map social connections and neighborhood contexts to see how supportive or risky environments spread across networks. About 2,700 racially diverse participants from five U.S. cities will be included and data will be collected remotely to protect privacy. The researchers aim to show how layered social inequalities concentrate risk and limit access to resources so future programs can better help those most affected.

Why it matters

Potential benefit: If successful, findings could guide new community- and network-based programs that reduce HIV transmission and substance use among marginalized groups.

How similar studies have gone: Previous social-network and neighborhood studies have identified risk patterns and helped target interventions, but this multi-city, layered focus on structural inequities is relatively new.
