Abstract:

目的了解天津市浴池男男性行为人群队列研究中失访的水平，分析失访的影响因素。方法 2012年1-6月在天津市招募活跃在浴池中的男男性行为人群开展基线调查，在此基础上开展前瞻开放式队列研究，每6个月随访一次，基线调查与随访调查均对研究对象开展问卷调查和HIV检测，对基线调查中HIV阴性的研究对象进行失访率分析，并采用单因素分析与logistic回归模型分析失访的影响因素。结果基线调查纳入研究对象658例，随访至42个月，队列失访率为26.3%（173/658）。多因素分析结果显示本市户籍（OR=0.552，95%CI： 0.377~0.808）、汉族（OR=0.197，95%CI： 0.066~0.593）、最近1年做过HIV检测（OR=0.481，95%CI： 0.326~0.710）、研究对象为男男卖淫者（OR=0.127，95%CI：0.028~0.585）、认为自己感染HIV的可能性高或较高（OR=0.285，95%CI：0.125~0.647）为失访的保护因素，而年龄≥35岁（OR=1.891，95%CI：1.022~3.500）是失访的危险因素。结论天津市浴池男男性行为人群队列研究中失访率较高，年龄、户籍、民族、HIV检测史、对自身感染HIV危险性的认知情况、是否为男男卖淫者等因素与队列失访有关，在后续开展队列研究时应制定适宜的纳入标准。

English Abstract:

Objective To understand the rate of follow-up lost in men who have sex with men (MSM) in a gay bathhouse cohort study in Tianjin and the associated factors. Methods The open cohort study in gay bathhouse was launched in 2012 in Tianjin, and the MSM for baseline survey were recruited from January to June 2012, while the follow up was carried out every six months. A questionnaire survey and HIV test were conducted in the study. The MSM who were HIV negative in the baseline survey in 2012 were used for follow up lost analysis. Univariate and multivariate logistic regression analysis were conducted to identify the factors associated with the lost of follow-up. Results A total of 658 gay bathhouse patrons were recruited in the baseline survey, at the end of 42-month follow-up period, 173 of them dropped out (26.3%). Multivariate analysis showed that the MSM who were local residents (OR=0.552, 95%CI:0.377-0.808), in Han ethnic group (OR=0.197, 95%CI:0.066-0.593), having received HIV test in the last year (OR=0.481, 95%CI:0.326-0.710), were male sex workers (OR=0.127, 95%CI:0.028-0.585), and believed to be at high risk for HIV infection (OR=0.285, 95%CI:0.125-0.647). They were more likely to receive follow-up but the MSM who were aged ≥35 years (OR=1.891, 95%CI:1.022-3.500) were more likely to be lost in the follow-up. Conclusion The lost rate of follow-up in MSM in the gay bathhouse cohort was high in Tianjin. Age, household registration, history of HIV test, the awareness of the risk to be infected with HIV and commercial homosex were factors associated with the follow-up rate in the MSM. It is necessary to conduct similar cohort study in targeted population on the basis of findings of this study.
