2. www.aids2014.org Overview 1,913 new HIV diagnoses in Los Angeles County (LAC) in 2011; 84% among MSM; 64% among 20 – 39 year olds (LACDPH, 2012) Substance use among young MSM (YMSM) is a major driver of HIV infection (Colfax et al., 2004; Drumright et al., 2006; Semple, Patterson, & Grant, 2002) Social venues (e.g., bars and clubs) may facilitate substance use and risky sexual behavior (Grov & Crow, 2012; Halkitis et al., 2005; Kubicek et al., 2007; Shoptaw et al., 2005)

13. www.aids2014.org Discussion YMSM social spaces are highly interconnected Results may be consistent with Theory of Syndemic Production (Stall et al., 2008) YMSM desire HIV prevention that is quick, convenient and delivered in social contexts they’re already attending (Holloway et al., 2012) Interventions in venues have had mixed success (Kelly et al., 1992; Elford et al., 2002) Innovative, venue-based strategies for engaging YMSM should be revisited

14. www.aids2014.org Limitations Data is from 2005 New venues open, old venues close Popularity of venues changes rapidly Does not include popular virtual venues Venue-based recruitment May overestimate the popularity of venues YMSM are attending Misses YMSM who do not attend gay social venues

15. www.aids2014.org Conclusion YMSM who use substances and engage in sexual risk behavior are integrated into gay communities Tailoring prevention to capitalize on the socialization patterns of YMSM may be an effective way to reach YMSM “where they’re at” Strategies that engage consortia of gay social venues to promote health and well-being of YMSM may be especially effective. More research on the acceptability of venue owner, staff engagement in public health efforts is needed
