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 behavioral characteristics, HIV infection and risk factors of network-based MSM in Shandong province from 2010 to 2014 and provide evidence for the targeted intervention of high-risk behavior among men who have sex with men (MSM). Methods From 2010 to 2014, eight city-based MSMs in the province were selected as the research objects to analyze their demographic characteristics, AIDS knowledge, behavioral characteristics and HIV status and influencing factors. Results A total of 1 640 online MSMs were enrolled. The average age was (27.43 ± 6.67) years old, mainly in the age group of 21 to 30 years old. The older the age, the higher the infection rate. The awareness of AIDS among subjects was on an upward trend (P <0.05). The prevalences of HIV antibodies were 0.2%, 0.3%, 1.0%, 2.3% and 8.4% respectively. Homosexual anal sex occurred in nearly six months, and the homosexual anal sex and heterosexual behavior increased with each condom use (P <0.05). Univariate analysis showed that in the age group of 31-40 years, the local resident lived within 3 months, the same-sex anal sex outside the province and the last six months, MSM who did not receive counseling and condom distribution / AIDS counseling HIV infection rate is high. Multivariate logistic regression analysis showed that within 3 months of local residence time, foreign citizenship and homosexual anal intercourse were the risk factors for HIV infection. However, condom delivery / AIDS counseling and testing were the protective factors against HIV infection. Conclusions Network MSM population insists on using condoms at a low level and the infection rate continues to rise. Targeted measures should be taken to strengthen the intervention.
