摘要
目的了解男男性行为人群(MSM)的性伴特征及高危性行为情况,探讨艾滋病病毒(HIV)在该人群中传播及向普通人群传播的模式,为针对性开展MSM高危性行为干预提供依据。方法通过网络、现场和社会小组同伴推动法招募研究对象,进行问卷调查、采血和检测。结果 857名调查者中,87人(10.2%)近6个月与固定异性发生过性行为,高危行为发生率73.6%(64/87);3人(0.4%)有非固定异性性伴。同性性伴类型中,173人(20.2%)有固定男性伴,631人(73.6%)有多次或偶遇男性伴,33人(3.9%)购买过商业性服务,15人(1.8%)提供过商业性服务。与以上四种性伴发生性行为中,高危性行为的发生率依次为22.5%(39/173)、54.5%(344/631)、15.2%(5/33)、33.3%(5/15)。近6个月735人(85.8%)有2种以上性伴类型。有固定男性伴的MSM发生多次或偶遇性行为、购买商业性行为、提供商业性行为的比例,分别低于没有固定男性伴的MSM(P<0.01,P=0.012,P=0.049)。结论 MSM的性伴类型复杂,性伴人数众多,高危性行为发生率高,不仅使HIV在MSM中容易传播,且使该人群成为艾滋病传播的桥梁人群,增加了HIV向普通人群传播的风险,需加强知识宣传和行为干预。
Objective In order to understand sexual partner characteristics and high-risk sexual behaviors among men who have sex with men（MSM）,to explore how human immunodeficiency virus（HIV）are transmitted among MSM and the general population,and provide evidence for intervention on high-risk behaviors among MSM.Methods The survey and serological tests were conducted on MSM by methods of network recruitment and site recruitment and social organizations recruitment.Results Among 857 MSM surveyed,87subjects（10.2%）had sexual intercourse with regular female sexual partners in the past 6 months,3（0.4%）had non-regular female partners,173（20.2%）had regular male partners,631（73.6%）had non-regular male partners or one-night-stand male partners,and 33（3.9%）had bought commercial sexual services from money boy,and 15（1.8%）had provided commercial sexual services for male clients.The rates of high risk behaviors with those four types of partners were 22.5%,54.5%,15.2%,33.3%,respectively.In the past six months,735（85.8%）subjects had two or more types of sexual partners.The ratio was higher for those that had boyfriends,subjects that had occasional male partners or one-nightstand male partners,bought homosexual intercourses or provided sex for money than those without non-regular male partners,（P〈0.000,P=0.012,P=0.049）.Conclusion High-risk sexual behavior and multiple sexual partners are prevalent among MSM,it not only helped make HIV spread more easily among MSM population,but also increased the risk to spread HIV among the general population.Awareness of HIV/AIDS related knowledge and behavioral interventions should be strengthened.
