MSM中HIV抗体阳性率及其影响因素分析

HIV detection rate and its influence factors among men who have sex with men

目的了解男男性行为人群(MSM)艾滋病病毒(HIV)的阳性检出率,探讨该人群感染HIV的影响因素。方法 2012年1-12月,在武汉市动员MSM参加HIV抗体快速检测,并调查收集人口学和行为学信息,HIV抗体筛查阳性者接受确证检测。结果共有7 123名符合条件的MSM参加了检测。分析表明,教育水平、现住址、过去3个月及最近1次肛交性行为安全套使用、找寻性伴地点、检测原因以及是否第1次参加HIV抗体检测,为影响MSM动员检测阳性发现的因素,差异均有统计学意义(P<0.05)。其中,外地、过去3个月有时使用和最近1次没有使用安全套、在浴池找寻性伴、第1次参加检测和感觉不舒服而参加检测的MSM,HIV阳性检出的风险分别是参照组的1.830、3.082、3.530、2.762、1.943和6.141倍。结论需要综合考虑,调整动员检测模式,设计活动及分配资源,注重实际效果,从而最大限度发现地HIV阳性者。

Objective To obtain HIV detection rate among men who have sex with men （MSM） and to explore the influence factors of HIV infection in this population. Methods MSM were mobilized to participate in the rapid detection of HIV antibody in Wuhan city from January to December, 2012. Meanwhile, information of demograph ics and behavior was collected. Confirmatory HIV antibody test was conducted in HIV positive individuals. Results Totally, 7123 MSM were enrolled in the study. Education level, current address, condom use in anal sex in the past 3 months and the last time, places to find sexual partners, detection reasons and whether or not the first time of participating in HIV antibody testing were the influence factors for HIV positive detection among MSM population, showing statistically significant differences for all factors （P〈0.05）. Compared with control group, fold changes of risk factors of foreigners, using condoms sometimes in the past three months and not use in the last time, finding sexual partners at bathing pool, the first time accepting HIV antibody testing and feeling unwell were 1. 830, 3. 082, 3. 530, 2. 762, 1. 943 and 6. 141, respectively. Conclusion Comprehensive considerations were needed and the patterns of test mobilization should be adjusted according to different characteristics among MSM. Activity de- sign and resource allocation should focus on actual effects to maximize HIV-positive detection.
