| 目的 通过队列研究分析天津市浴池MSM人群HIV新发感染状况及影响因素,为在MSM人群中开展HIV感染的预防和干预提供依据。方法 以经常光顾天津市某同性恋浴池、曾发生过男男性行为的MSM为研究对象,于2011年4月至2013年9月采用同伴推动法招募研究对象,建立MSM人群开放性队列,完成HIV检测和基线调查,并进行跟踪随访检测。调查内容包括人口学特征、艾滋病相关知识知晓情况、艾滋病相关行为情况等信息。以随访过程中"HIV阳转"为结局因变量,同时,将从研究对象进入队列到出现HIV阳转的时间为时间因变量,应用Cox比例风险模型进行浴池型MSM人群HIV新发感染影响因素的分析。结果 调查期间符合条件的研究对象733例,共新发HIV感染59例,队列随访累积观察时间为7 384.9人月,HIV新发感染率为9.59/100人年(95%CI:7.3/100人年~11.92/100人年)。多因素 Cox 回归分析显示,天津市浴池型MSM人群的危险因素包括:年龄较低者相比较年长者艾滋病知识知晓率低者(HR=1.82,95%CI:1.03~2.66)相比较知晓率高者,多性伴者(HR=1.74,95%CI:1.26~2.58)相比较固定性伴者,正在感染梅毒者(HR=2.36,95%CI:1.31~3.27),均易发生HIV的新发感染。结论 同性恋浴池MSM人群中年龄较低、艾滋病知识知晓率低、多性伴、梅毒感染为该人群HIV新发感染的危险因素,应针对危险因素加强浴池型MSM人群HIV新发感染的监测和干预。 |

| Objective To investigate incidence of HIV infection and identify associated risk factors among men who have sex with men (MSM) in common bathing pools in Tianjin. Methods A prospective cohort study was conducted among the MSM recruited in a common bathing pool in Tianjin from 2011 to 2013. A total of 733 MSM were surveyed to obtain the information about their sociodemographic characteristics, HIV-related knowledge awareness and sexual behaviors, and subsequent follow-up surveys were carried out every four months. Cox regression analysis was conducted to identify the risk factors for HIV infection. Results A total of 59 HIV infection cases were found in the 2.5-years follow-up survey. The cumulative follow-up time was 7 384.9 person- months. The incidence rate of HIV infection was 9.59/100 person-year. The multivariate Cox regression analysis showed that young age, low score of HIV/AIDS knowledge awareness (HR=1.82, 95%CI:1.03-2.66), having two and more sexual partners during past 6 months (HR=1.74, 95%CI: 1.26-2.58) and syphilis (HR=2.36, 95%CI:1.31-3.27) were significantly associated with HIV infection in this MSM cohort. Conclusions Low score of HIV/AIDS knowledge awareness, young age, having two and more sexual partners during past 6 months and syphilis were the risk factors for HIV infection in MSM in common bathing pools. It is necessary to strengthen the HIV surveillance and intervention in this population. |
