目的探讨HIV抗体阴性男男性行为人群(men who have sex with men,MSM)队列保持率及其影响因素,为制定失访控制措施提供依据。方法利用浙江省2011年建立的MSM队列资料,采用χ2检验和logistic回归多因素分析方法,研究社会人口学特征、艾滋病知识知晓率、性行为以及艾滋病防治服务利用等情况对队列保持的影响。结果纳入队列的387名MSM,15个月随访率为58.40%,知晓“一个人感染了艾滋病是否可以从外表上看出来”这一条目的人维持率低(OR=0.482,95%CI为0.236-0.983,P<0.05)、知晓“保持单一性伴侣是否可以降低艾滋病感染的风险”这一条目的人保持率低(OR=0.306,95%CI为0.100-0.942,P<0.05),最近3个月未接受HIV检测者保持率低(OR=0.487,95%CI为0.311-0.762,P<0.01)。结论知识宣传教育必要但不充分,关注检测服务利用率低者,制定个性化方案,加强联系,减少失访。
Objective To investigate the cohort retention rate of HIV-negative men who have sex with men (MSM) and its influencing factors, and to provide a basis for the development of follow-up control measures. Methods The data of MSM cohort established in Zhejiang Province in 2011 were analyzed by Chi-square test and logistic regression multivariate analysis to study the effect of social demographic characteristics, awareness rate of AIDS knowledge, sexual behavior and AIDS prevention and treatment service on the cohort maintenance. Results A total of 387 MSM cohorts were enrolled in the cohort with a 15-month follow-up of 58.40% and a low rate of maintenance (OR = 0.482, 95% CI (OR = 0.306, 95% CI: 0.100-0.942, P <0.05), with a lower retention rate of 0.236-0.983, P <0.05) The retention rate of non-HIV patients in the last 3 months was low (OR = 0.487, 95% CI 0.311-0.762, P <0.01). Conclusions Knowledge publicity and education is necessary but not sufficient, paying close attention to the low rate of utilization of testing services, formulating individualized programs, strengthening contacts and reducing loss of follow-up.
