摘　　要：目的 分析2011—2019年湖南省男男性行为哨点数据,了解男男性行为者(men who have sex with men,MSM)HIV、梅毒感染状况及性行为特征,为下一步制定MSM防控策略提供依据。方法 2011—2019年在湖南省选择男男性行为人群较多的城市设立MSM哨点,采用滚雪球抽样、MSM人群活动场所招募和网络招募方法,对MSM进行匿名问卷调查和采集血样,收集被调查者的人口学信息、性行为和血清学信息,分析其变化趋势和感染HIV、梅毒的影响因素。结果 2019年HIV抗体阳性率和梅毒抗体阳性率分别为6.00%和2.38%,历年有线性趋势变化(均P<0.05)。艾滋病知识知晓率为94.00%。最近六个月性伴类型:仅有同性性伴、有同性且有异性性伴、有同性且有商业性伴、有多种性伴、仅有异性性伴、无性伴的比例分别为83.63%,6.38%、0.75%,0.25%、8.00%和1.00%。logistic回归多因素分析,离异或丧偶(OR=1.85,95%CI:1.08~3.16)、样本来源于网络招募(OR=1.94,95%CI:1.32~2.85)、最近六个月仅有同性性伴(OR=2.41,95%CI:1.53~3.78)更容易感染HIV。样本来源于网络招募(OR=15.93,95%CI:5.08~49.97)、最近六个月仅有同性性伴(OR=2.45,95%CI:1.44~4.17)、最近六个月有同性且有异性(OR=2.09,95%CI:1.10~3.94)、最近六个月有多种性伴(OR=3.23,95%CI:1.27~8.23)更容易感染梅毒。结论 2011—2019年湖南省MSM人群HIV抗体和梅毒抗体阳性率处于中等水平,结合互联网和人群心理特点,有针对性地开展干预工作,加强艾滋病知识的宣传,提高安全套的使用率,从而降低该人群的艾滋病传播。Objective To analyze the sentinel data of male-male sexaul behavior in Hunan Province from 2011 to 2019,to understand the HIV and syphilis infection status and sexual behavior characteristics of MSM,and to provide a basis for formulating prevention and control strategies for MSM in the next step.Methods From 2011 to 2019,MSM outposts were set up in cities with more MSM in Hunan Province.Snowball sampling method,MSM crowd activity site recruitment and online recruitment were used to recruit MSM.An anonymous questionnaire survey was conducted,and blood samples were collected.The respondents' information about demography,sexual behavior and serology was collected,and the changing trends and the factors influencing HIV and syphilis infection were analyzed.Results In 2019,the positive rates of HIV antibody and syphilis antibody were 6.00% and 2.38% respectively.There was a linear changing trend over the years(all P<0.05).The awareness rate of AIDS knowledge was 94.00%.As for the types of sexual partners in the last six months,only same-sex sexual partners,same-sex and heterosexual sexual partners,same-sex and commercial sexual partners,multiple sexual partners,only heterosexual sexual partners and asexual partners accounted for 83.63%,6.38%,0.75%,0.25%,8.00% and 1.00% respectively.Multivariate logistic regression analysis showed that divorced or widowed MSM(OR=1.85,95%CI:1.08-3.16),online recruitment MSM based on sample sources(OR=1.94,95%CI:1.32-2.85),and MSM having only same-sex sexual partners in the last six months(OR=2.41,95%CI:1.53-3.78) were more likely to be infected with HIV.Online recruitment MSM based on sample sources(OR=15.93,95%CI:5.08-49.97),MSM having only same-sex sexual partners in the last six months(OR= 2.45,95%CI:1.44-4.17),MSM having same-sex and opposite-sex sexual partners in the last six months(OR= 2.09,95%CI:1.10-3.94),and MSM having multiple sexual partners in the last six months(OR= 3.23,95%CI:1.27-8.23) were more likely to be infected with syphilis.Conclusion The positive rates of HIV and
