2020年福州市男男性行为人群艾滋病监测分析

Analysis of AIDS surveillance results among men who have sex with men in Fuzhou in 2020

目的了解福州市男男性行为人群艾滋病知识知晓程度及其相关行为对HIV感染状况的影响。方法2020年通过辖区社会组织,采用现场干预、滚雪球和网络招募方式招募男男性行为人群(MSM),开展行为学和血清学调查。结果共调查3220人,调查对象以网络招募为主,占81.74%(2632/3220),年龄(31.47±8.94)岁。艾滋病知识知晓率为93.76%,不同来源、文化程度和年龄的调查对象艾滋病知识知晓率差异有统计学意义(P<0.01)。HIV抗体检测阳性率为2.24%(72/3220),单因素分析显示,不同婚姻状况、文化程度、艾滋病知识知晓率、吸毒情况、最近一年患性病情况、最近一次与同性发生性行为安全套使用情况、最近6个月与同性发生肛交性行为安全套使用情况、既往接受干预情况的调查对象艾滋病抗体阳性率差异有统计学意义(P<0.05)。多因素Logistic回归分析显示,吸毒(OR=13.52)、最近一年患性病(OR=1.75)、未婚(OR=2.64)是MSM人群HIV感染的危险因素,文化程度高(OR=0.07)是保护性因素(P<0.05)。结论福州市MSM人群不安全性行为比例和HIV感染率处于较高水平,应继续扩大MSM人群检测和安全套推广等综合干预措施,以控制HIV疫情进一步扩散。

Objective To understand the awareness rate of AIDS knowledge among men who have sex with men in Fuzhou and the influence of their related behaviors on HIV infection status.Methods Men who have sex with men(MSM)were recruited through jurisdictional social organizations by using the methods of on-site interventions,snowballing and online recruitment to conduct behavioral and serological surveys in 2020.Results A total of 3220 people were surveyed,with 81.74%(2632/3220)of the respondents recruited mainly by the internet,aged(31.47±8.94)years.The awareness rate of AIDS knowledge was 93.76%.The differences in the awareness rates of AIDS knowledge among the respondents with different sources,education level and age were statistically significant(P<0.01).The rate of HIV antibody test positivity was 2.24%(72/3220).Univariable analysis showed that there were statistically significant differences(P<0.05)in the rates of HIV antibody positivity among respondents with different marital status,education level,awareness rate of AIDS knowledge,drug use,sexually transmitted diseases in the last year,condom use in the last sex with the same sex,condom use in the last six months of anal sex with the same sex,and previous intervention received.Multivariable logistic regression analysis demonstrated that drug use(OR=13.52),having STD last year(OR=1.75),and being unmarried(OR=2.64)were risk factors for HIV infection in the MSM population,while high education level was protective factors(P<0.05).Conclusion The proportion of unsafe sex and infection rate of HIV among the MSM population in Fuzhou is at a high level,so that comprehensive interventions such as testing and condom promotion in the MSM population should continue to be expanded for controlling the further spread of HIV epidemic.
