The effects of neighborhood context on sexual risk behavior are understudied, particularly for Black heterosexual men who do not inject drugs or report heavy drug use. Evidence of a generalized HIV epidemic (>1 %) among Black heterosexuals in low-income urban U.S. communities underscores the importance of examining the effects of neighborhood context on Black heterosexual men's sexual risk, however. We used structural equation modeling to test the pathways between neighborhood context (neighborhood disorder, personal violence, neighborhood threats), depression, substance use, and sexual risk behavior. Participants were 526 self-identified Black heterosexual men, ages 18-45, recruited via randomized venue-based probability sampling in Philadelphia, PA. Analyses of model fit statistics from Mplus indicated statistically significant direct pathways between neighborhood context, depression, substance use, and sexual risk behavior. The total indirect effect of neighborhood context on sexual risk behavior through substance use was also significant. The study's results highlight a need for more research on neighborhood context and sexual HIV risk, and for multilevel interventions to address the effects of negative neighborhood context on Black heterosexual men's sexual HIV risk.
