北京市2009-2013年MSM艾滋病哨点监测结果分析

目的了解北京市男男性行为人群（MSM）的行为特征,以及艾滋病病毒（HIV）、梅毒、丙型肝炎病毒（HCV）的感染状况。方法 2009-2013年,在北京市MSM活动场所和网络招募MSM,通过面对面访谈收集MSM的高危行为信息、艾滋病知识知晓情况,并采集血液标本检测HIV、梅毒螺旋体、HCV抗体。结果 2009-2013年,共调查2997名MSM,各年MSM的平均年龄分别为（29.61±8.22）岁、（28.68±7.06）岁、（29.27±7.73）岁、（30.41±8.11）岁、（32.81±9.28）岁。各年MSM的艾滋病基本知识总体知晓率为92.37%（569/616）、96.35%（580/602）、92.92%（538/579）、94.33%（566/600）、94.17%（565/600）;接受过同伴教育的比例分别为27.60%（170/616）、13.12%（79/602）、21.07%（122/579）、66.67%（400/600）、51.50%（309/600）;与同性发生肛交性行为时每次都使用安全套的比例,分别为44.54%（253/568）、46.05%（262/569）、50.46%（273/541）、60.68%（341/562）、51.37%（282/549）;与异性发生性行为时每次都使用安全套的比例,分别为14.43%（14/97）、29.41%（25/85）、21.95%（18/82）、38.46%（35/91）、29.67%（27/91）。HIV抗体阳性检出率分别为5.03%（31/616）、6.64%（40/602）、7.08%（41/579）、9.50%（57/600）、10.50%（63/600）,有逐年增加趋势。结论北京市MSM中HIV感染率较高,应加强同伴教育和安全套推广等干预措施,降低艾滋病在MSM中的传播。

Analysis of sentinel surveillance results among men who have sex with men in Beijing from 2009 to 2013

Objective To analyze behavior characteristics of men who have sex with men （MSM） and their sta- tus of HIV, syphilis and HCV infection in Beijing. Methods MSM were recruited from MSM locations and web- sites in Beijing from 2009 to 2013. Data on high risk sexual behaviors as well as knowledge related to HIV/AIDS were collected by face-to-face interview. Blood samples were tested for HIV, syphilis and HCV antibodies. Results Totally, 2997 MSM were interviewed from 2009 to 2013, and their average age was （29.61--4-_8.22）, （28.68! 7.06）, （29.27!7.73）, （30. 41_--4-8. 11） and （32.81-1-9.28）, respectively. The awareness of HIV/AIDS prevention knowledge was 92.37%（569/616）, 96.35%（580/602）, 92.92~（538/579）, 94.33%（566/600） and 94.17%（565/ 600）, respectively. The proportion of receiving peer education was 27.60%（170/616）, 13.12%（79/602）, 21. 070//oo （122/579）, 66.67~//00（400/600） and 51.50% （309/600）. The rate of using condom consistently while having anal sex with male partner over last 6 months was 44.54%（253/568）, 46.05% （262/569）, 50.46%（273/541）, 60.68% （341/562） and 51.37% （282/549）, respectively. The rate of using condom consistently while having sex with fe- male partner was 14.43%（14/97）, 29.41%（25/85）, 21.95%（18/82）, 38.46%（35/91） and 29.67%（27/91）, respectively. The positive rates of HIV antibody were 5. 03%（31/616）, 6.64%（40/602）, 7.08%（41/579）, 9.50% （57/600） and 10.50%（63/600） , with an increasing trend year by year. Conclusions The prevalence rate of HIV among MSM in Beijing was high. Specific HIV/AIDS peer education and condom promotion for this population should be strengthened to reduce HIV/AIDS spreading among MSM.
