To investigate factors associated with HIV infection and the frequency and willingness of male circumcision among men who have sex with men (MSM) in Chengdu city, China.
A cross-sectional survey provided information on participants' demographics, risk behaviors, circumcision, and uptake of HIV prevention services.
Of 570 participants, 13.3% were infected with HIV and 15.9% with syphilis. An estimated 43.0% of respondents reported having unprotected receptive anal intercourse, and 58.9% reported having ≥2 male sexual partners in the past 6 months. Multivariable logistic regression revealed that syphilis, more male sex partners, predominantly receptive anal intercourse, and exclusively receptive male sex were associated with HIV infection. Higher level of education and peer education service were inversely associated with HIV infection. Nearly a fifth (18.0%) of participants were circumcised. More than half of uncircumcised participants expressed willingness to be circumcised.
This study reveals a high prevalence of HIV and syphilis among MSM in Chengdu province of China. The frequency of unprotected receptive anal intercourse and multiple male sexual partnerships highlight the urgency for an effective comprehensive HIV prevention strategy. Although the willingness to accept male circumcision (MC) is high, further research is needed to assess the protective effective of MC among MSM.
调查中国成都市男男性行为者(MSM)中与HIV感染相关的因素以及男性包皮环切术的实施频率和意愿。
一项横断面调查提供了参与者的人口统计学信息、风险行为、包皮环切术及HIV预防服务的接受情况。
在570名参与者中,13.3%感染了HIV,15.9%感染了梅毒。估计43.0%的受访者报告有无保护的肛交行为,58.9%报告在过去6个月中有≥2名男性性伴侣。多变量逻辑回归显示,梅毒、更多的男性性伴侣、主要是接受肛交以及只接受男性性行为与HIV感染相关。较高的教育水平和同伴教育服务与HIV感染呈负相关。近五分之一(18.0%)的参与者接受了包皮环切术。超过一半未接受包皮环切术的参与者表示愿意接受包皮环切术。
本研究揭示了中国四川省成都市男男性行为者中HIV和梅毒的高流行率。无保护的肛交行为频率和多个男性性伴侣凸显了制定有效的综合HIV预防策略的紧迫性。尽管接受男性包皮环切术(MC)的意愿较高,但仍需要进一步研究以评估MC在男男性行为者中的保护效果。
