Pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention intervention; however, most studies of PrEP adherence and persistence among men who have sex with men (MSM) have been conducted with MSM who live in urban areas. The experiences of PrEP-using MSM in non-urban areas might differ due to increased barriers to culturally competent care. We examined similarities and differences among urban and non-urban PrEP-using MSM in the southern United States, the region with the highest number of annual HIV diagnoses. We surveyed a total of 78 (n = 25 non-urban, n = 53 urban) PrEP-using MSM. Self-reported adherence was high across all participants. No differences were observed with respect to PrEP persistence, source of PrEP, or reasons for PrEP initiation. Fewer non-urban than urban men reported STI testing in the past 12 months. Overall, we observed few differences comparing urban and non-urban PrEP-using MSM. Additional studies are needed to describe differences in PrEP initiation comparing urban and non-urban MSM.

Gay, bisexual and other men who have sex with men (GBMSM) experience greater health disparities, and concern about other health conditions may decrease engagement in HIV prevention. This study assessed perceived threat and impact of HIV relative to other health concerns among GBMSM. Data were from a national online survey of GBMSM conducted between August and September 2015. Participants ranked concern about contracting HIV and impact of HIV on their health compared with other health conditions. The association of HIV threat and impact with recent condomless anal sex (CAS) and HIV testing were assessed using regression models. Among 466 participants, threat and impact of HIV were ranked lower compared to cancer, Alzheimer's and heart disease. Concern about getting HIV was associated with greater odds of recent HIV testing (adjOR 1.1, 95%CI 1.02–1.18) and lower CAS (adjOR 0.86, 95%CI 0.78–0.94). Among GBMSM, other health conditions may be perceived as a greater threat and higher impact on health compared with HIV. Integrating complex health care concerns with HIV prevention strategies may increase engagement in prevention. [ABSTRACT FROM AUTHOR]

Factors such as race, masculinity, and sexually transmitted infections have been documented to influence partner selection in men who have sex with men (MSM). Pre-exposure prophylaxis (PrEP) has received mixed evaluations as a responsible step in HIV prevention and as an enabler of risker sexual practices. PrEP may consequently serve as an additional factor in partner choice. We examine the role that PrEP use and "promiscuity" play in affiliation and dating decisions by men who have sex with men with different HIV and PrEP stati. We invited 450 MSM across the United States from a smartphone geo-locating sex application to complete a survey of which 339 successfully finished the task. The survey contained vignettes of fictional men who were promiscuous or monogamous and either taking PrEP or not. Participants provided responses on whether to affiliate with these characters in three social domains: as friends, dates, or sex partners. Neither PrEP nor promiscuity influenced friendship choices. There was a preference for dating monogamous characters. Critically, PrEP influenced sexual affiliations for HIV negative individuals who showed a preference for PrEP-using characters. The pattern of results provides quantitative evidence for PrEP-based sexual sorting aimed at reducing risk of HIV transmission. [ABSTRACT FROM AUTHOR]

Three quarters of new HIV infections in the US are among men who have sex with men (MSM). In other populations, incarceration is a social determinant of elevations in viral load and HIV-related substance use and sex risk behavior. There has been limited research on incarceration and these HIV transmission risk determinants in HIV-positive MSM. We used the Veterans Aging Cohort Study (VACS) 2011-2012 follow-up survey to measure associations between past year and prior (more than one year ago) incarceration and HIV viral load and substance use and sex risk behavior among HIV-positive MSM (N = 532). Approximately 40% had ever been incarcerated, including 9% in the past year. In analyses adjusting for sociodemographic factors, past year and prior incarceration were strongly associated with detectable viral load (HIV-1 RNA >500 copies/mL) (past year adjusted odds ratio (AOR): 3.50 95% confidence interval (CI): 1.59, 7.71; prior AOR: 2.48 95% CI: 1.44, 4.29) and past 12 month injection drug use (AORs > 6), multiple sex partnerships (AORs > 1.8), and condomless sex in the context of substance use (AORs > 3). Past year incarceration also was strongly associated with alcohol and non-injection drug use (AOR > 2.5). Less than one in five HIV-positive MSM recently released from incarceration took advantage of a jail/prison re-entry health care program available to veterans. We need to reach HIV-positive MSM leaving jails and prisons to improve linkage to care and clinical outcomes and reduce transmission risk upon release. [ABSTRACT FROM AUTHOR]
