我国14城市男男性行为人群艾滋病感染状况及艾滋病知识、态度、行为研究

目的 调查分析我国14个城市男男性行为者(men who have sex with men,MSM)艾滋病感染状况及艾滋病知识、态度及行为特征.方法 采取整群抽样法在全国内抽取14个大中城市,采用同伴推动抽样法(RDS)选取6101例MSM进行问卷调查,同时采集血液检测人类免疫缺陷病毒(HIV)和梅毒螺旋体.采用SPSS等软件对数据进行统计学分析.结果 6101例MSM中,HIV感染率为6.3%(384/6101),梅毒感染率为14.0%(854/6101),艾滋病防治知识知晓率为59.7%(3644/6101),最近6个月内付钱获得性行为、为获得金钱而发生性行为的比率分别为6.2%(378/6101)和11.2%(683/6101),最近1个月与男性伴性行为时均使用安全套的比率为39.2%(2392/6101),最近1次与男性伴性行为时使用安全套的比率为65.2%(3978/6101).结论 调查的MSM中HIV感染率高,艾滋病防治知识较为缺乏,高危行为普遍存在,应尽快采取措施干预HIV在MSM中的传播.

HIV infection and KAP status among men who have sex with men in 14 Chinese cities

Objective To explore the current status of HIV infection and HIV-related knowledge, attitude and practice (KAP) among men who have sex with men (MSM) in 14 cities in China. Methods A cluster sampling method was administrated and 14 large or medium cities were selected. The respondent-driven sampling (RDS) was also used to conduct a questionnaire survey in 6101 MSM. Blood specimens were collected for HIV and syphilis testing. Results A total of 6101 MSM were selected and investigated,with an HIV infection rate of 6.3% (384/6101) and a syphilis infection rate of 14.0% (854/6101). The proportion of MSM knowing correct HIV/AIDS knowledge was 59.7% (3644/6101) ;6.2% (378/6101) and 11.2% (683/6101) of the respondents ever had buying sex or selling sex in the last six months respectively; the proportion of consistent condom-using each time while with male partners in the last month was 39.2% (2392/6101). The proportion of condom-using while with male partners was 65.2% (3978/6101) in the last time among MSM. Conclusion A high HIV infection rate was observed among MSM with limited HIV/AIDS awareness and high risk behaviors. It is necessary to initiate a rapid response to prevent HIV spreading in MSM.
