摘　　要：目的了解2010-2014年山东省网络型的男男性行为者(Men Who have Sex with Men,MSM)行为特征、HIV感染及其危险因素,为针对性实施男男性行为人群高危行为干预提供依据。方法 2010-2014年选择全省8个市网络型MSM为研究对象,分析其人口学特点、艾滋病知识、行为特征及HIV感染状况及影响因素。结果共招募网络型MSM 1 640人,平均年龄为(27.43±6.67)岁,以21~30岁年龄组为主,年龄越大,感染率越高;研究对象艾滋病知识知晓率呈上升趋势(P<0.05);HIV抗体阳性率分别为0.2%、0.3%、1.0%、2.3%、8.4%;近半年发生同性肛交性行为、每次使用安全套的同性肛交性行为和异性性行为均呈上升趋势(P<0.05);单因素分析显示,31~40岁年龄组、本地居住时间在3个月以内、外省籍、最近半年发生过同性肛交性行为、未接受过安全套发放/艾滋病咨询检测的MSM HIV感染率高。多因素Logistic回归分析显示,本地居住时间在3个月以内、外省籍及最近半年与同性发生肛交是HIV感染的危险因素,而接受过安全套发放/艾滋病咨询检测是预防HIV感染的保护因素。结论网络型MSM人群坚持使用安全套水平较低,感染率持续上升,应采取针对性措施强化干预。Objective To understand the behavior characteristics, prevalence of HIV and risk factors among network - based men who have sex with men（MSM） in Shandong province. Methods Five consecutive cross - sectional surveys from 2010 to 2014 provided demographics, HIV -related knowledge, behavioral characteristics, HIV infection status and their influencing factors in Shandong province. Results Of the 1640 participants, the mean age was 27.43 ± 6. 67 years old, mainly in 21 - 30 age group. The higher the age, the higher the infection rate. The awareness rate of HIV/AIDS knowledge was increasing. The HIV antibody positive rates were 0. 2% ,0. 3%, 1.0% ,2. 3% ,8. 4%. The proportion of ever having anal sex behaviors,condom use during male anal sex and condom use during female sex in past six months showed an increasing trend. Univariate analysis showed those aged between 31 - 40, living in the local time less than three months, the non - Shandong provincial residence, ever having anal sex in past six months, never received HIV intervention services had high HIV infection. The multivariate logistic regression analysis showed that the local residence time less than three months, the non - Shandong provincial residence and sexual intercourse with the same sex in the past six months were risk factors of HIV infection, and accepting condoms/AIDS counseling and testing were the protective factors. Conclusion The Internet has become an important platform for MSM dating. Network - based MSM persisted in using condoms at low level. The rate of infection is rising fast, and it will be the focus group of AIDS prevention and control work in the future.
