目的了解云南省昆明市浴池型男男性行为者(MSM)的艾滋病病毒(HIV)感染现况,探索影响昆明市浴池内与MSM HIV感染的相关因素。方法采用横断面研究,在昆明市浴池现场,用偶遇抽样法招募200名MSM进行问卷调查及HIV抗体快速检测。结果调查对象年龄中位数38岁,最小年龄18岁,最大年龄66岁。与非浴池型MSM相比,浴池型MSM年龄偏大、文化程度偏低。艾滋病知识知晓率87.5%(175人);最近3个月在浴池内发生过插入性性行为的比例为74.5%(149人);发生群交的比例为29.5%(44/149),群交时坚持使用安全套者的比例为31.8%(14/44);当知道对方是HIV感染者或病人时,仍有24.0%(48人)的调查对象不会停止与其发生性行为。浴池型MSM的HIV阳性检出率为12.0%(24人)。多因素分析结果显示,浴池型MSM中HIV感染的主要影响因素包括:文化程度较低,不观察性伴身体健康情况,在浴池内活动时间较长及不知晓艾滋病相关知识(P<0.05)。结论浴池型MSM的HIV感染率较高,尤其是文化程度较低、长时间在浴池内活动及不知晓艾滋病知识的MSM,应加大针对MSM艾滋病知识的宣传力度,加强对高危人群的行为干预。
Objective To understand the status of HIV infection in bath-typed MSM in Kunming, Yunnan and to explore the factors influencing HIV infection in MSM in Kunming bath. Methods A cross-sectional study was conducted. In the bathing scene in Kunming City, 200 MSMs were enrolled in a casual sampling method for questionnaire survey and HIV antibody rapid test. Results The median age of respondents was 38 years old, the youngest was 18 years old, and the oldest was 66 years old. Bath-type MSMs are older and less educated than non-bath-type MSMs. AIDS awareness rate was 87.5% (175 people); in the last 3 months, 74.5% (149 people) had intercourse sexual activity in the bathing pool; 29.5% (44/149) The percentage of condom users was 31.8% (14/44). When knowing each other was HIV-infected or sick, 24.0% (48) of the respondents did not stop having sex with them. The positive rate of HIV-positive tuberculosis MSM was 12.0% (24). The results of multivariate analysis showed that the main influencing factors of HIV infection in bath-type MSM were: lower education, unobserved physical health, longer activities in the bath and no knowledge of AIDS (P <0.05). Conclusion The MSM with bath-type MSM has a high HIV infection rate, especially MSM with low educational level, long time in the bath and knowledge of AIDS, and should step up publicity to MSM’s AIDS knowledge and strengthen behavioral intervention .
