目的了解男男性行为者(MSM)近期接受人类免疫缺陷病毒(HIV)检测现状及其影响因素。方法 2014年4—10月,以绵阳市辖区内MSM为对象,在固定场所应用滚雪球抽样法,进行调查对象招募和自填式匿名行为学调查和血清学检测。结果共调查1 097例,近期做过HIV检测的为76.7%(841/1 097),其中75.8%(832/1 097)做过检测并知道结果,不同地区差异均有统计学意义(分别为χ~2=71.018、68.101,均P<0.01)。近期接受、未接受过检测的HIV感染率分别为2.0%(17/841)和9.8%(25/256)(χ~2=31.967,P<0.01)。多因素分析显示,年龄、认识当地MSM朋友人数、接受预防服务、寻找性伴地方、HIV感染是近期接受HIV检测的独立影响因素(均P<0.05)。结论该市MSM近期接受HIV检测率较高,地区间不平衡,社会活动网络、预防服务是促进因素。HIV检测有效提高了感染者发现和安全性行为。
Objective To understand the recent status of human immunodeficiency virus (HIV) detection in men who have sex with men (MSM) and its influencing factors. Methods From April to October 2014, MSM in Mianyang municipality was used as a target, and the snowball sampling method was used in fixed places to investigate the recruitment and self-signed anonymous behavioral investigations and serological tests. Results A total of 1 097 cases were investigated. Among them, 76.7% (841/1 097) had done HIV testing recently, of which 75.8% (832/1 097) had done tests and knew the results, and the differences were statistically significant in different regions χ ~ 2 = 71.018,68.101, all P <0.01). The rates of recent and uninformed HIV infection were 2.0% (17/841) and 9.8% (25/256), respectively (χ ~ 2 = 31.967, P <0.01). Multivariate analysis showed that age, HIV / AIDS awareness among local MSM friends, prevention services and sexual partners were the independent risk factors of HIV testing (all P <0.05). Conclusion The city MSM recently received a high rate of HIV detection, inter-regional imbalances, social activity networks, prevention services are contributing factors. HIV testing effectively increases the detection and safety of infected individuals.
