2010-2014年淮安市男男性行为人群安全套使用及HIV和梅毒感染情况

Prevalence of HIV infection and syphilis, condom use among men who have sex with men in Huaian city during 2010 to 2014

目的分析淮安市男男性行为者安全套使用情况及艾滋病和梅毒检测阳性情况,为制订防治对策和干预措施提供依据。方法采用"滚雪球"、网络招募等方法招募对象,由经过专业培训的调查员对其进行面对面的问卷调查,并采血样进行艾滋病病毒(HIV)、梅毒和丙型病毒性肝炎病毒(HCV)抗体检测。结果 2010-2014年共监测男男性行为者1 752人,HIV和梅毒抗体检测阳性率分别为5.24%和6.51%,各年份间HIV阳性率比较差异均无统计学意义(P>0.05);但梅毒阳性率比较差异均有统计学意义(P<0.05)。最近一次同性肛交及同性商业性性行为安全套平均使用率分别为66.11%和70.59%;最近一次异性性行为安全套使用率为34.91%,不同年份间使用率比较差异均有统计学意义(P<0.05)。除最近一次同性肛交人群中是否使用安全套对梅毒抗体检测阳性率的影响有统计学意义(P<0.05)外,其他性行为特征人群不同安全套使用间梅毒及HIV抗体检测阳性率差异均无统计学意义(P>0.05)。男男性行为者接受安全套宣传及艾滋病咨询检测和同伴教育分别占74.54%和60.39%,各年份间两种干预措施接受率比较差异均有统计学意义(P<0.05)。结论淮安市男男性行为人群安全套使用率较低,HIV和梅毒阳性率较高,应继续加强健康教育和干预措施。

Objective To analyze the situation of condom use and human immunodeficiency virus(HIV)/acquired immunodeficiency syndrome(AIDS) and syphilis among men who have sex with men(MSM) in Huaian city, and to provide evidence for developing associated prevention and intervention measures. Methods During 2010-2014, subjects were recruited by snowball sampling or network recruitment. A face to face questionnaire survey was conducted among them by professional investigators. Blood samples were collected for HIV, syphilis and hepatitis C virus(HCV)testing. Results A total of 1 752 participants were recruited during 2010 to 2014. The positive rates of HIV and syphilis antibody were 5.24% and 6.51% respectively. There was no significant difference in the positive rates of HIV between different years(P>0.05), but there were statistically significant differences in the positive rates of syphilis(P<0.05). The average condom use rate in recent anal homosexual behavior and commercial homosexual behavior were 66.11% and70.59%, respectively. The condom use rate of the latest heterosexual behavior was 34.91%. The annual difference of condom use in heterosexual behavior was significant(P<0.05). The difference of syphilis infection rate between participants using condom or not was only significant in MSM who have homosexual behavior recently(P<0.05). Among the participants,74.54% accepted intervention measures of condom broadcast and voluntary HIV counseling and test, and 60.39% received peer education. The acceptance rates of receiving intervention services were significantly different annually(P<0.05).Conclusion The condom use rate is relatively low among MSM in Huaian City, and HIV and syphilis positive rates were relatively high. Thus it was necessary to strengthen the health education and intervention services among MSM.
