To evaluate the effect of a community-based intervention project among men who have sex with men (MSM) after two-year implementation.
Comprehensive interventions among MSM in 18 cities of seven provinces were conducted. The pre-intervention questionnaire was conducted in September 2006 and 5178 subjects were investigated through snowball method. In May 2007, post-questionnaire was conducted and 5460 subjects were investigated through snowball or accompanied recommendation method. For each subject, a questionnaire was completed, including basic information, HIV/AIDS knowledge, behaviours and intervention status. At the same time, 5 ml intravenous blood sample was collected to detect HIV infection and evaluated the intervention effect.
After two-year implementation, the awareness rate of HIV/AIDS knowledge increased from 76.0% (3933/5178) in 2006 to 90.5% (4943/5460) in 2008 (chi(2) = 451.786, P < 0.001); the rate of condom use in the last anal sex with males increased from 58.0% (2382/4105) to 76.7% (3643/4750) (chi(2) = 215.491, P < 0.01); the rate of consistent condom use in the last six months increased from 28.2% (1163/4118) to 44.5% (2114/4753) (chi(2) = 264.606, P < 0.01); the proportion of MSM receiving HIV antibody test increased from 18.8% (973/5170) to 39.1% (2136/5454) (chi(2) = 530.181, P < 0.01); and the HIV infection rate increased from 2.3% (118/5178) to 5.0% (271/5427) (chi(2) = 47.613, P < 0.01).
The MSM community-based intervention project achieved some good results after two-year implementation and contributed to an increase in HIV/AIDS knowledge and safe sex.
评估一项针对男男性行为者（MSM）的社区干预项目实施两年后的效果。
在七个省份的18个城市对男男性行为者开展综合干预。于2006年9月进行干预前问卷调查，通过滚雪球法调查了5178名对象。2007年5月进行干预后问卷调查，通过滚雪球或同伴推荐法调查了5460名对象。为每名对象填写一份问卷，内容包括基本信息、艾滋病病毒/艾滋病知识、行为及干预情况。同时，采集5毫升静脉血样检测艾滋病病毒感染情况并评估干预效果。
实施两年后，艾滋病病毒/艾滋病知识知晓率从2006年的76.0%（3933/5178）升至2008年的90.5%（4943/5460）（χ² = 451.786，P < 0.001）；最近一次与男性肛交时的避孕套使用率从58.0%（2382/4105）升至76.7%（3643/4750）（χ² = 215.491，P < 0.01）；最近六个月坚持使用避孕套的比例从28.2%（1163/4118）升至44.5%（2114/4753）（χ² = 264.606，P < 0.01）；接受艾滋病病毒抗体检测的男男性行为者比例从18.8%（973/5170）升至39.1%（2136/5454）（χ² = 530.181，P < 0.01）；艾滋病病毒感染率从2.3%（118/5178）升至5.0%（271/5427）（χ² = 47.613，P < 0.01）。
针对男男性行为者的社区干预项目实施两年后取得了一些良好效果，有助于提高艾滋病病毒/艾滋病知识水平及安全性行为。
