Abstract

We assessed socio-structural and behavioral correlates of preexposure prophylaxis (PrEP) for HIV infection among a sample of high-risk HIV-negative men who have sex with men (MSM) in Los Angeles, California. Participants from an ongoing 5-year prospective cohort study investigating the direct impacts of substance use on HIV transmission dynamics were enrolled between February 2015 and January 2017. All men completed a computer-assisted self-interview every 6 months that assessed recent (past 6 months) PrEP use and socio-structural and behavioral factors. Of the total 185 MSM (mean age = 29 years) included in the study, majority were African American (40%) or Hispanic (41%) and reported current health insurance coverage (80%). In multivariable analysis using log-binomial regression, having health insurance coverage [adjusted prevalence ratio (aPR) 2.02; 95% confidence interval (CI) 1.01 to 4.01, p = 0.04] was associated with recent PrEP use. Unstable housing (aPR = 0.44, 95% CI 0.22 to 0.90, p = 0.02) was associated with lower PrEP use. Behavioral factors associated with recent PrEP use include sex with a HIV-positive partner (aPR = 3.63, 95% CI 1.45 to 9.10, p = 0.01), having six or more sex partners (aPR = 2.20, 95% CI 1.26 to 3.82, p = <0.01), and popper use (aPR = 2.76, 95% CI 1.58 to 4.84, p = <0.01). In this sample of predominantly racial/ethnic minority MSM, socio-structural and behavioral factors were important factors associated with recent PrEP use. These findings provide considerations for intervention development to promote PrEP use among key groups of MSM.
