Nonvolitional sex and HIV-related sexual risk behaviours among MSM in the United States.

ABSTRACT: We estimated the prevalence of lifetime nonvolitional sex (NVS) among MSM by demographic characteristics, and characterized its association with HIV-related sexual risk behaviours among MSM in the United States.The National Survey of Family Growth (NSFG) is a nationally representative cross-sectional survey of the United States.NSFG data from recent cycles 2002, and 2006-2010 were weighted and analysed for men aged 18-44 years who reported ever having anal or oral intercourse with another male. Associations of lifetime NVS (forced sex by men or women) and age of first NVS experience (<18 vs. ?18 years), with HIV-related sexual risk behaviour outcomes in the past 12 months (i.e. sex with two or more male sex partners; exchanged sex for money or drugs; sex with IDU; sex with HIV-positive person; sex with two or more female sex partners) were assessed using adjusted prevalence ratios (aPR).An estimated 3?226?872 or 5.8% of men aged 18-44 years were identified as MSM with 24.6% of them reporting ever experiencing NVS. MSM reporting NVS at age 18 years or older were more likely to have had sex with an IDU [aPR?=?4.40; 95% confidence interval (95% CI) 1.78-10.88] and exchanged sex for money or drugs (aPR?=?2.52; 95% CI 1.17-5.43) in the past 12 months compared with those not reporting NVS. NVS for MSM less than 18 years of age was associated with exchanging sex for money or drugs.Effective interventions to raise awareness of NVS among MSM and to offer support for MSM who have experienced NVS are needed.

Project description:BACKGROUND:Despite evidence supporting pre-exposure prophylaxis (PrEP) efficacy, there are concerns regarding the feasibility of widespread PrEP implementation among men who have sex with men (MSM). To inform the development of targeted PrEP delivery guidelines, sexual risk trajectories among HIV-negative MSM were characterized. METHODS:At semiannual visits from 2003 to 2011, HIV-negative MSM (N = 419) participating in the Multicenter AIDS Cohort Study provided data on sexual risk behaviors (SRBs) since their last visit. Based on their reported behaviors, participants were assigned a SRB score at each visit as follows: 0 = no insertive or receptive anal intercourse, 1 = no unprotected insertive or receptive anal intercourse, 2 = only unprotected insertive anal intercourse, 3 = unprotected receptive anal intercourse with 1 HIV-negative partner, 4 = condom serosorting, 5 = condom seropositioning, and 6 = no seroadaptive behaviors. Group-based trajectory modeling was used to examine SRB scores (<4 vs. ?4) and identify groups with distinct sexual risk trajectories. RESULTS:Three sexual risk trajectory groups were identified: low-risk (n = 264; 63.0%), moderate-risk (n = 96; 22.9%; mean duration of consecutive high-risk intervals ?1 year), and high-risk (n = 59; 14.1%; mean duration of consecutive high-risk intervals ?2 years). Compared to low-risk group membership, high-risk group membership was associated with younger age (in years) [adjusted odds ratio (AOR) = 0.92, 95% confidence interval (CI): 0.88 to 0.96], being White (AOR = 3.67, 95% CI: 1.48 to 9.11), earning an income ?$20,000 (AOR = 4.98, 95% CI: 2.13 to 11.64), distress/depression symptoms (Center for Epidemiologic Studies Depression Scale ? 16) (AOR = 2.36, 95% CI: 1.14 to 4.92), and substance use (AOR = 2.00, 95% CI: 1.01 to 3.97). CONCLUSIONS:Screening for the sociodemographic and behavioral factors described above may facilitate targeted PrEP delivery during high-risk periods among MSM.

Project description:Regular HIV testing enables early identification and treatment of HIV among at-risk men who have sex with men (MSM). Characterizing HIV testing needs for Internet-using MSM informs development of Internet-facilitated testing interventions. In this systematic review we analyze HIV testing patterns among Internet-using MSM in the United States who report, through participation in an online study or survey, their HIV status as negative or unknown and identify demographic or behavioral risk factors associated with testing. We systematically searched multiple electronic databases for relevant English-language articles published between January 1, 2005 and December 16, 2014. Using meta-analysis, we summarized the proportion of Internet-using MSM who had ever tested for HIV and the proportion who tested in the 12 months preceding participation in the online study or survey. We also identified factors predictive of these outcomes using meta-regression and narrative synthesis. Thirty-two studies that enrolled 83,186 MSM met our inclusion criteria. Among the studies reporting data for each outcome, 85 % (95 % CI 82-87 %) of participants had ever tested, and 58 % (95 % CI 53-63 %) had tested in the year preceding enrollment in the study, among those for whom those data were reported. Age over 30 years, at least a college education, use of drugs, and self-identification as being homosexual or gay were associated with ever having tested for HIV. A large majority of Internet-using MSM indicated they had been tested for HIV at some point in the past. A smaller proportion-but still a majority-reported they had been tested within the year preceding study or survey participation. MSM who self-identify as heterosexual or bisexual, are younger, or who use drugs (including non-injection drugs) may be less likely to have ever tested for HIV. The overall findings of our systematic review are encouraging; however, a subpopulation of MSM may benefit from targeted outreach. These findings indicate unmet needs for HIV testing among Internet-using MSM and identify subpopulations that might benefit from targeted outreach, such as provision of HIV self-testing kits.

Project description:OBJECTIVES:In the United States, all men who have sex with men (MSM) were banned from donating blood from 1985 through 2015. In 2016, the guideline was amended such that men who had sexual contact with other men within the previous 12 months could not donate blood. We aimed to identify blood donation practices and their relationship with HIV risk and testing among young adult MSM (YMSM) at risk for having HIV. METHODS:In 2014, we recruited HIV-negative non-Hispanic black, Hispanic, and non-Hispanic white YMSM aged 18-24 from across the United States through social media platforms to complete an online survey. Among these YMSM who previously donated blood, we conducted a secondary analysis examining the relationship between having donated blood within the past 12 months and sexual risk behavior from recent condomless anal intercourse (CAI), HIV testing, and self-perceived risk of having an undiagnosed HIV infection. RESULTS:Of the 2261 YMSM surveyed, 1104 (48.8%) had ever previously donated blood and 305 (13.5%) had donated blood within the past 12 months. Of the 305 blood donors, 50 (16.4%) had ever had CAI before their most recent blood donation. Among YMSM who donated blood, past-12-month blood donation was more likely among YMSM who never had CAI (adjusted odds ratio [aOR] = 1.84; 95% confidence interval [CI], 1.24-2.73) than among YMSM who had CAI and more likely among YMSM who believed it was not possible at all that they had an undiagnosed HIV infection (aOR = 1.57; 95% CI, 1.14-2.16) than among YMSM who believed there was any possibility of having an undiagnosed HIV infection; it was not related to past-12-month HIV testing. CONCLUSIONS:YMSM donated blood frequently, suggesting that the deferral process in place did not prevent YMSM from donating blood. The current donor screening process should be reconsidered if it is to prevent YMSM from donating blood. Future research could identify screening questions that permit YMSM with a low risk of HIV infection to donate blood while maintaining the safety of the blood supply.
