目的 探讨重庆市人类免疫缺陷病毒(human immunodeficiency virus,HIV)阳性男男性行为者(men who have sex with men,MSM)同性群交行为现状及相关因素,为制定针对性的干预策略和措施提供依据.方法 2022年6月-2023年6月,由重庆市2个社会组织负责招募HIV阳性MSM完成问卷调查,调查内容包括:社会人口学特征、性取向、HIV阳性及高危行为、HIV污名化感知评分、焦虑症状评分和抑郁症状评分等.采用二元logistic回归分析模型分析同性群交行为相关因素.结果 共调查HIV阳性MSM 1 501人,26.4％(396/1 501)报告既往有同性群交行为,9.3％(139/1 501)报告近6个月有同性群交行为,其中无保护同性群交行为比例为56.8％.多因素logistic回归分析结果显示,性取向为同性恋(OR=2.221,95％CI:1.116～4.422)、HIV 确诊≥5 年(OR=5.405,95％CI:1.940～15.059)、HIV污名化感知评分越高(OR=1.075,95％CI:1.034～1.117)、抗病毒治疗依从性不佳(OR=2.748,95％CI:1.493～5.059)、近6个月使用男同社交媒体(使用1种:OR=3.117,95％CI:1.006～9.657;使用 2 种:OR=6.065,95％CI:1.848～19.901;使用3 种:OR=11.665,95％CI:3.043～44.711)、近6个月使用 Rush poppers(OR=9.178,95％CI:4.584～18.380)、近 6 个月使用冰毒(OR=38.186,95％CI:11.427～127.602)及发生无保护性肛交行为(OR=3.227,95％CI:1.824～5.711)的 HIV阳性MSM更可能发生同性群交行为(均P＜0.05).结论 重庆市HIV阳性MSM同性群交行为普遍,同性群交中安全套使用率较低,应重点关注该人群污名化感知、男同社交媒体使用、物质使用及同性群交行为,以减少HIV或性传播疾病(sexually transmitted diseases,STDs)进一步传播.
