2010-2013年重庆市部分男男性行为人群认知艾滋病和感染状况分析

目的分析重庆市男男性行为(men who have sex with men,MSM)人群近几年HIV流行状况及相关性行为和检测史的变化情况。方法 2010-2013年每年通过社会组织的积极动员,以滚雪球以及网络招募的方式招募调查对象,进行面对面问卷调查,所获得资料运用SPSS 13.0软件进行统计学分析。结果 2010-2013年,调查对象中30岁以下结婚比例很低,均不足6%,艾滋病知识知晓率高。最近6个月发生肛交行为比例较高,安全套坚持使用率不足50%。高年龄组HIV及梅毒感染率均较高,18~24岁年龄组HIV感染率从2010年的11.4%增长到2013年的17.6%,30~34岁年龄组HIV感染率从2010年的10.5%增长到2013年的26.4%。多因素分析结果显示,文化程度、近6个月安全套坚持使用情况、HIV检测史及梅毒感染状况是感染HIV的影响因素。结论尽管重庆市MSM人群知识知晓率较高,开展了安全套促进、推进HIV检测服务,梅毒感染率也有所下降,但艾滋病HIV感染率却一直处于较高的水平,加强感染者管理,及时尽早进行治疗,以及针对不同层次人群寻求更有效的干预措施迫在眉睫。

Sex behaviors and HIV infection status among men who have sex with men in Chongqing, 2010-2013

Objective To understand the prevalence of risk sex behaviors and HIV infection status among men who have sex with men in Chongqing in recent several years. Methods Face to face questionnaire survey was conducted among the MSM recruited by snowballing methods in the communities in Chongqing from 2010 to 2013. All the data were analyzed with SPSS 13.0 software. Results Only 6% of the MSM aged 30 years were got married, but the awareness of AIDS related knowledge was high among them. Most MSM surveyed had anal sex in the past 6 months, but the condom use rate was less than 50%. The positive rates of HIV and syphilis antibodies were high in age group 34 years. From 2010 to 2013,the HIV infection rate increased from 11.4% to 17.6% in age group 18-24 years and from 10.5% to 26.4% in age group 30-34 years. The result of logistic regression analysis showed that influencing factors of HIV infection included education level, condom usage in recent 6 months, HIV test history and syphilis infection. Conclusion Although the MSM had high awareness of AIDS related knowledge and behavior interventions had been conducted among them in Chongqing, the HIV infection rate was still high. It is urgent to conduct early antiretroviral treatment and more effective targeted behavior interventions in MSM.
