Use situation of Rush among men who have sex with men in Chongqing City and its influencing factors analysis

目的了解重庆市男男性行为者(MSM)的Rush使用情况及其影响因素,为制定相关防控措施提供依据。方法采用横断面调查,于2022年1月至2023年2月通过网络招募和社会组织转介招募重庆市MSM进行匿名电子问卷调查,获取其人口学特征、近6个月性伴和性行为特征、Rush使用情况、HIV和梅毒抗体检测情况等信息。使用χ^(2)检验和非条件多因素logistic回归分析Rush使用的影响因素。结果共调查494名MSM,Rush的使用率为22.1%。多因素logistic回归分析结果显示,首次同性性行为年龄<18岁(OR=2.715,95%CI:1.353~5.451)、近6个月存在无保护同性肛交(OR=2.237,95%CI:1.355~3.693)、近6个月有多个同性固定性伴(OR=3.610,95%CI:1.449~8.993)、近6个月有同性临时性伴(OR=3.734,95%CI:2.221~6.280)是MSM使用Rush的危险因素。结论重庆市MSM人群的Rush使用率较高,应开展针对性的干预措施,特别加强对首次同性性行为年龄在18岁以下、近6个月存在无保护同性肛交、近6个月有多个同性固定性伴及有同性临时性伴人群的宣教,以降低其Rush的使用率,从而降低该人群感染和传播艾滋病的风险。
