目的了解山东省不同活动场所男男性行为者(MSM)行为特征及艾滋病感染状况,为制定有效的防控策略提供依据。方法 2015年4-6月,对济南、青岛、菏泽等8个MSM哨点3 210名MSM进行问卷调查,同时采集其静脉血5mL,实验室检测人类免疫缺陷病毒(human immunodeficiency virus,HIV)抗体。结果不同活动场所MSM在年龄、婚姻状况、本地居住时间、文化程度间比较,差异有统计学意义(P<0.001);HIV抗体检出率为4.5%(146/3 210),VCT点感染率最高,为9.6%(57/594),且高于其他4组(x~2=47.26,P<0.001)。多因素结果显示,外省籍、最近6个月与同性发生肛交行为未坚持使用安全套、未接受HIV干预服务、被诊断患过性病、到VCT咨询检测者与HIV感染高风险有关。结论未来应重点加大对浴室和外省籍MSM的关注,借助网络干预等方式扩大目标人群的干预范围,从而控制MSM人群中HIV的流行。

Methods From April to June 2015, 3 210 MSMs from 8 MSM sentinels in Jinan, Qingdao and Heze were surveyed, and 5 mL venous blood samples were also collected for detection of human immunodeficiency virus (HIV) antibody . Results There was significant difference in MSM among different age, marital status, local residence time and educational level (P <0.001). The detection rate of HIV antibody was 4.5% (146/3 210) The highest was 9.6% (57/594) and higher than the other 4 groups (x ~ 2 = 47.26, P <0.001). Multivariate analysis showed that outside provinces, the last 6 months with homosexual anal intercourse did not adhere to the use of condoms, did not receive HIV intervention services, was diagnosed with sexually transmitted diseases, to VCT counseling and high risk of HIV infection. Conclusion In the future, attention should be paid to bathroom and MSM in other provinces.
