四川省绵阳市男男性行为者不同本地居住时间其社会行为特征

目的了解男男性行为者(MSM)本地居住时间现状,分析不同本地居住时间者的社会行为特征。方法2018年2-10月采用滚雪球抽样,对四川省绵阳市MSM进行本地居住时间、社会行为等问卷调查和血清学检测。运用χ^2检验、Logistic回归模型进行不同本地居住时间其社会行为特征的单因素及多因素分析。结果回收合格问卷1132份,本地居住时间≤6个月占4.7%,>6个月占95.3%。在本地居住时间≤6个月者HIV阳性率为9.4%、>6个月为3.4%(P=0.059)。多因素分析,相对于本地居住时间≤6个月,本地居住时间>6个月的社区朋友≥5人(aOR=2.089)、参加社区活动(aOR=2.232)、中/高安全感(aOR=3.447)、互联网及其他方式寻找性伴(aOR=3.014)、近6个月肛交有保护(aOR=2.915)的可能大,近6个月有商业性行为(aOR=0.206)、肛交数≥2人(aOR=0.428)可能小。结论当地MSM以本地长期居住者为主,不同本地居住时间其社会行为存在差异,居住时间短的HIV感染风险大,应针对性加强行为干预。

Objective To understand the current situation of local living time of men who have sex with men (MSM), and we analyze of the characteristics of social behaviors among people with different local residence time. Methods From February to October 2018, snowball sampling was used to investigate the local living time and social behavior of MSM in Mianyang City, Sichuan Province. Chi-squared test and logistic regression model were used to understand single factor and multifactor analysis of the relationship between local living time and social behavior. Results Totally 1 132 qualified questionnaires were collected, the local living time ≤6 months was 4.7%, >6 months was 95.3%. The positive rate of HIV in local living time ≤6 months was 9.4%, >6 months was 3.4% (P=0.059). Multifactor analysis showed that compared with local living time ≤6 months, the number (≥5) of community friends with local residence time > 6 months (aOR=2.089), participating in community activities (aOR=2.232), medium / high sense of security (aOR=3.447), Internet and other ways to find sexual partners (aOR=3.014), anal intercourse protected in recent 6 months were more likely (aOR=2.915) , commercial sex in recent 6 months (aOR=0.206), and the number of anal intercourse ≥ 2 (aOR=0.428) were likely to be small. Conclusion The local MSM is mainly local long-term residents, differences in social behavior between different local residence times, the risk of HIV infection with short living time is high and behavioral intervention should be strengthened.
