目的通过分析长春市2013-2015年男男同性性行为者艾滋病高危行为的流行情况以及血清学检测结果,为在该人群中开展艾滋病防治工作提供理论依据。方法收集2013-2015年长春市男男同性性行为者艾滋病哨点的监测数据,对艾滋病高危行为和血清学检测结果进行统计学分析。结果 2013-2015年长春市男男同性行为人群中,以青壮年、未婚、本地居民为主,80%以上的监测对象发生过同性肛交,最近6个月发生同性肛交时使用安全套的比例分别为81.39%、45.09%和43.17%,呈明显降低趋势,差异有统计学意义(χ2=30.854,P<0.001)。监测对象对艾滋病防治知识知晓率分别为95.36%、97.86%和99.35%;HIV抗体阳性率分别为5.80%、12.85%和15.50%,呈逐年升高趋势;梅毒抗体的阳性率分别为9.78%、11.37%和3.26%。结论虽然长春市男男同性性行为人群对艾滋病防治相关知识的知晓率较高,但仍有较高比例的艾滋病高危行为发生,存在严重的知识与行为脱节现象,男男同性性行为人群中HIV的感染率呈逐年升高的趋势,需要进一步加强对男男同性性行为者的行为干预,进而有效控制疫情的蔓延。

Objective To analyze of the prevalence of HIV / AIDS risk behaviors among MSM（ men who have sex with men） and the serological test results during 2013 and 2015 in Changchun,and provide a theoretical basis for the prevention and treatment of HIV / AIDS in this population. Methods HIV / AIDS sentinel surveillance data of MSM during 2013 and2015 in Changchun were collected. The surveillance results of the AIDS high risk behavior and the serological test results were analyzed. Results Among the MSM in Changchun during 2013 and 2015,the main population was young,unmarried and local residents. More than 80% of the monitoring object occurred in homosexual anal sex. However,the condom use rates of the homosexual anal sex in the past six months were 81. 39%,45. 09% and 43. 17% from 2013 to 2015. It was significantly decreased（ χ2= 30. 854,P〈 0. 001）. The knowledge awareness rate of HIV / AIDS prevention and control was 95. 36%,97. 86% and 99. 35%,respectively. The positive rate of HIV antibody was 5. 80%,12. 85% and 15. 50%and the positive rate of syphilis antibody was 9. 78%,11. 37% and 3. 26% from 2013 to 2015. Conclusion Although the awareness rate of AIDS prevention and control knowledge of MSM in Changchun is higher,however,the proportion of HIV/ AIDS risk behavior is still high in the MSM population. There is a serious phenomenon of the disjoint between knowledge and behavior. The HIV infection rate in MSM is increasing year by year. It should be strengthened the intervention of the MSM to control the spread of the epidemic effectively.
