摘要
目的了解山东省男男同性性行为人群(MSM)艾滋病病毒(HIV)、梅毒感染状况及其影响因素,为进一步做好MSM艾滋病防治工作提供依据。方法 2010年4-7月,按照多阶段整群随机抽样方法选取MSM人群,由经过统一培训的调查员对MSM进行面对面问卷调查,抽取静脉血检测艾滋病、梅毒抗体,对影响HIV、梅毒感染的因素进行Logistic回归分析。结果共调查3 200名MSM,收集有效问卷3 086份,有效问卷率96.44%,采集血液标本3 073份。调查对象最小15岁,最大74岁,平均年龄为(26.36±6.38)岁。最近六个月与同性发生过肛交性行为者占72.68%(2 243/3 086),其中每次都使用安全套者占32.59%(731/2 243);最近六个月与同性发生商业性行为者占11.83%(365/3 086),最近六个月与异性发生性行为者占22.72%(701/3 086)。HIV抗体阳性检出率1.01%(31/3 073),梅毒抗体阳性检出率4.69%(144/3 073)。Logistic回归分析显示,年龄较大、最近六个月发生同性肛交性行为、最近一年患过性病、没有接受安全套宣传发放服务,是HIV/梅毒感染的危险因素。结论山东省MSM人群HIV感染率较低,但梅毒感染率较高,提示MSM人群存在HIV广泛传播的可能性,需要在MSM人群中进一步加强艾滋病宣传和行为干预。

Methods A total of 3 200 MSM were selected by multi-stage cluster random sampling from April to July, 2010. Questionnaire survey was carried out among MSM by trained investigator, Blood samples were taken to examine antihodies of HIV and syphilis. As- sociated factors of HIV and syphilis were examined hy multiple logistic regression analysis. Results Totally, 3 086 questionnaires were received from 3 200 MSM, with an average age of 26. 366.38 years, the youngest being 15 years, and the oldest being 74 years. The rate of anal sex in the past six months was 72.68M（2 243/3 086）, and only 32.59%（731/2 243） of them used condom consistently; 11.83% （365/3 086） of the participants had sold or paid for sex with males, and 22.72M （701/3 086） of them had female sexual partners in the past half year. The prevalence of HIV and syphilis was 1.01% （31/3 073） and 4.69 % （144/3 073） respectively. The analysis indicated that older MSM, having anal sex during the past 6 months, having sexual transmitted diseases in the past year, un- availability of condom promotion services were risk factors associated with HIV/ syphilis infection. Conclusion The prevalence of HIV and syphilis is at a low level , but there are high risk behaviors among MSM in Shandong Province. It is urgent to strengthen AIDS related health education and provide behavioral intervention to MSM.
