Sociodemographic and Behavioral Risk Correlates of PrEP Interest and Use Among Young Adults Experiencing Homelessness in Los Angeles

Young adults experiencing homelessness (YAEH) are at elevated risk for HIV compared to their stably housed peers.

Preexposure prophylaxis (PrEP) is highly effective at preventing HIV infection, yet YAEH have been largely overlooked in PrEP efforts to date despite YAEH reporting high overall interest in PrEP.

We assessed individual, social, and structural variables associated with PrEP interest and use among a sample of 195 YAEH (ages 18–25) recruited from drop-in centers across Los Angeles County who met criteria for HIV risk.

In the current sample, though most had heard of PrEP (81.0%), the majority were not interested in taking PrEP (68.2%) and only a minority had used/were using PrEP (11.8%).

YAEH who identified as sexual and/or gender minority, reported knowing someone who had used PrEP, or recently accessed sexual health services were more likely to have used and/or reported interest in using PrEP.

Those who reported more episodes of heavy drinking were less likely to report having used PrEP.

Suggestions are provided for better integrating PrEP-related services into existing behavioral and health service programs for YAEH, as well as leveraging peers and fostering positive social norms to reduce PrEP-related stigma and increase interest and use of PrEP among YAEH.
