Background: Black men who have sex with men (BMSM) and some who also have sex with women (BMSMW) account for over 70% of new HIV infections in the United States representing an elevated HIV risk in this group, also informing risks of HIV transmission to other BMSM and female sexual partners. Settings: We examined trajectories of self-reported substance use, HIV-related sexual risk behaviors, and psychosocial vulnerabilities among BMSMW versus BMSM over a 1-year study period. Methods: We analyzed baseline, 6-, and 12-month follow-up data from the HIV Prevention Trials Network "BROTHERS" Study (HPTN 061; n = 1126). Categorizing participants by sexual partner type across 3 time points: (1) BMSMO: having male and no female partners across assessments and (2) BMSMW: having sex with male and one or more female partners at least at 1 time point. Using generalized estimating equations, we estimated associations between being BMSMW (versus BMSMO) and changes in psychosocial vulnerability, substance use, and HIV-related sexual risk behaviors. Results: Generalized estimating equation models controlling for sociodemographics, time-varying effects, and intervention status showed that BMSMW versus BMSMO had 50% increased odds of crack use, 71% increased odds of alcohol use during condomless anal intercourse (CAI), 51% greater odds of using drugs at last CAI, and twice the odds of receiving goods at last CAI. Conclusions: Findings show stable and comparatively elevated illicit drugs, alcohol, and exchange sex during last CAI among BMSMW. Future intervention research should focus on ways to address changes in substance-related HIV-transmission behaviors over time in this population of men. [ABSTRACT FROM AUTHOR]

The article explores the relation between social and behavioral indicators and HIV, herpes simplex virus-2 (HSV-2), and/or Chlamydia-discordant sexual partnership. The characteristics of respondents were identified by analyzing the data collected in a social network study in Bushwick, New York City. Results show that HSV-2 and Chlamydia discordance were linked with sexual behavior, including multiple partnerships, while HIV partnership discordance is mainly associated with injection drug use.

Background: Given the disproportionate rates of incarceration and lower life expectancy (LE) among Black sexual minority men (BSMM) and Black transgender women (BTW) with HIV, we modeled the impact of decarceration and screening for psychiatric conditions and substance use on LE of US BSMM/BTW with HIV. Methods: We augmented a microsimulation model previously validated to predict LE and leading causes of death in the US with estimates from the HPTN 061 cohort and the Veteran's Aging Cohort Studies. We estimated independent associations among psychiatric and substance use disorders, to simulate the influence of treatment of one condition on improvement on others. We used this augmented simulation to estimate LE for BSMM/BTW with HIV with a history of incarceration under alternative policies of decarceration (ie, reducing the fraction exposed to incarceration), screening for psychiatric conditions and substance use, or both. Results: Baseline LE was 61.3 years. Reducing incarceration by 25%, 33%, 50%, and 100% increased LE by 0.29, 0.31, 0.53, and 1.08 years, respectively, versus no reductions in incarceration. When reducing incarceration by 33% and implementing screening for alcohol, tobacco, substance use, and depression, in which a positive screen triggers diagnostic assessment for all psychiatric and substance use conditions and linkage to treatment, LE increased by 1.52 years compared with no screening or decarceration. Discussion: LE among BSMM/BTW with HIV is short compared with other people with HIV. Reducing incarceration and improving screening and treatment of psychiatric conditions and substance use could substantially increase LE in this population. [ABSTRACT FROM AUTHOR]

The article presents a study on the risk factors of group sex events (GSEs) in acquiring sexually transmitted infection (STI) and HIV in Brooklyn, New York. The study aims to describe the prevalence of HIV and STI among GSEs and GSE attendees. It also describes the characteristics of individual and network of GSEs and GSE attendees through the respondents sera and urine samples. The study concluded that self-reported GSE attendance and participation were usual among the high-risk urban network.

Background: Exposure to incarceration is associated with increased risk of mortality, and HIV is cited as a leading cause of death. Yet, few studies have examined the association between incarceration and mortality among people with HIV (PWH), specifically whether and how increasing exposure to incarceration increases risk of mortality. We compared mortality by different incarceration exposures and HIV status. Methods: We conducted a prospective cohort study of participants in the Veterans Aging Cohort Study from January 2011 to August 2017 (N = 5367). The primary exposure was incarceration by 3 measures: (1) any (ever/never); (2) frequency; and (3) cumulative duration. Stratifying by HIV status and controlling for age, race, and sex, we used Cox Proportional Hazard models to estimate adjusted hazard ratios (AHRs) and 95% confidence intervals (CIs). Results: Incarceration was associated with increased risk of mortality compared with those never incarcerated for PWH (AHR 1.37; 95% CI: 1.13 to 1.66) and those uninfected (AHR 1.24; 95% CI: 0.99 to 1.54), but the association was only statistically significant among PWH. Increasing frequency of incarceration was associated with higher risk of mortality in both groups: for PWH, AHRs 1.13, 1.45, and 1.64 for 1, 2-5; 6+ times, respectively, for uninfected, AHRs 0.98, 1.35, and 1.70 for 1, 2-5, and 6+ times, respectively. Conclusions: PWH were at increased risk of mortality after incarceration, and repeated exposure to incarceration was associated with mortality in both groups in a dose--response fashion. This increased risk of mortality may be mitigated by improving transitional health care, especially HIV care, and reducing incarceration. [ABSTRACT FROM AUTHOR]
