Nonvolitional sex and HIV-related sexual risk behaviours among MSM in the United States. (24th August 2015) - Nasrullah, Muazzam
Abstract : Objective: 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. Design: The National Survey of Family Growth (NSFG) is a nationally representative cross-sectional survey of the United States. Methods: 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). Results: 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. Conclusion: Effective interventions to raise awareness of NVS among MSM and to offer support for MSM who have experienced NVS are needed.
