天津市男男性行为大学生HIV感染影响因素分析

  目的  分析天津市大学生青年男男性行为者(young men who have sex with men, YMSM)人类免疫缺陷病毒(HIV)感染的相关影响因素，为制定大学生艾滋病的防控政策及策略提供重要参考。  方法  2018年1月1日—12月31日，由深蓝组织于同志浴池、酒吧、QQ、微信和同性交友软件等渠道进行招募，收集18~24岁共470名大学生YMSM的HIV感染情况的4个方面影响因素(一般人口学特征、不安全性行为、成瘾性物质使用情况、HIV基本知识知晓情况)进行回顾性分析。  结果  470名研究对象中，HIV感染者21名(4.47%)。单因素Logistic回归分析显示，年龄、首次性行为年龄、HIV基本知识、是否吸烟、是否使用精神活性物质、是否梅毒感染可能与HIV感染有关(P值均 < 0.05)。多因素Logistic回归分析结果显示，首次性行为年龄提前(OR=21.20，95%CI=3.09~145.43)、使用精神活性物质(OR=5.07，95%CI=1.77~14.48)、HIV基本知识欠缺(OR=3.38，95%CI=1.33~8.63)的大学生YMSM更易感染HIV(P值均 < 0.05)。  结论  天津大学生YMSM中有着较高的HIV感染率，应重视此类人群，结合其鲜明特征制定更有针对性的校园艾滋病预防方案。
