摘要:
目的 了解2011-2015年芜湖市男男性行为人群（men who have sex with men，MSM）安全套使用情况及其影响因素，为当地制订该人群的艾滋病防治措施提供依据。方法 利用《全国艾滋病哨点监测方案》的问卷，在2011-2015年哨点监测期内对约400例MSM进行问卷调查，收集有关艾滋病知识、高危行为等资料，并采集血液进行艾滋病、梅毒、丙肝检测。结果 5年共调查MSM 2 037例。调查对象中最近半年发生肛交性行为安全套每次使用率分别是23.24%、38.13%、37.41%、47.15%和82.22%，呈现逐年上升趋势（χ趋势2=266.778，P<0.001）；多因素Logistic回归分析结果显示最近半年发生同性商业性行为、与女性发生性行为、最近一年诊断过性病的调查对象最近半年每次肛交性行为坚持使用安全套比例较低；血清学检测结果显示调查对象艾滋病、梅毒和丙肝检测阳性率分别是5.84%、12.37%和0.69%，5年的艾滋病阳性率分别是4.36%、3.36%、6.48%、6.48%和8.64%。结论 芜湖市MSM安全套使用率有所提升，但仍然不高；艾滋病、梅毒感染率还在逐年上升，应继续加强该人群针对性宣传教育和行为干预工作。
Abstract:
Objective To investigate status of condom use and influencing factors among men who have sex with men(MSM) in Wuhu City from 2011 to 2015,so as to provide basis for making prevention measures. Methods About 400 MSM were investigated annually by questionnaires according to the National Protocol for HIV Sentinel Surveillance during 2011-2015 and blood samples were collected for HIV, syphilis and HCV testing. Results Of a total 2 037 participants, the rates of condom use in anal intercourse in the past 6 months were respectively 23.24%, 38.13%, 37.41%, 47.15% and 82.22% with a upward trend from 2011 to 2015(χtrends test2=266.778,P<0.001). Multivariate Logistic regression analysis showed that participants who had commercial sex in the past 6 months, having sex with females, being diagnosed sexual transmitted diseases(STDs) in past year were risk factors of condom use in anal intercourse. The prevalence of HIV, TP, and HCV were 5.84%, 12.37%, 0.69% respectively with increasing trends of HIV and TP prevalence. The positive rates of HIV were 4.36%,3.36%,6.48%,6.48% and 8.64% respectively from 2011 to 2015. Conclusions Rates of condom use among MSM in Wuhu city from 2011 to 2015 slightly rose. The prevalence of HIV and TP increased every year. Propaganda education and behavioral intervention among MSM should be strengthened to reduce risk sex behaviors to stop STDs/AIDS epidemics, especially among MSM who have commercial homosexual behavior or heterosexual behavior.
