摘 要: 目的:估计上海市闵行区艾滋病人群(HIV感染者和艾滋病患者)的规模,了解闵行区艾滋病疫情情况,制定并实施有针对性的防治干预措施。方法:采用多阶段随机抽样的方法在上海市闵行区社区人群中招募调查对象,并进行问卷调查,利用网络规模迭加法估计艾滋病人群规模。结果:共调查合格对象3 907人,其中男性1 912人(48.9%),女性1 995人(51.1%);调查对象平均年龄为(40.54±11.69)岁。初步估计上海市闵行区居民社交网络规模均值为206人,经过反向预测法调整校正后为240人;进一步依据网络规模迭加法并结合态度法校正得该区艾滋病人群规模为368人(95% CI:291.19~444.17),约占上海市闵行区常住人数的0.03%. 结论:采用网络规模迭加法对艾滋病人群的规模进行估计,其操作简单易行,但仍需对结果进行适当校正。

Abstract: Objective: To estimate the population size of people living with HIV/AIDS (PLWHA) in Minhang district, Shanghai, and understand the epidemic of AIDS as well as develop specific prevention measures. Methods: A multiple stages random sampling method was used to recruit eligible participants among general population in Minhang district, Shanghai, and the questionnaire interviews were followed. The population size of PLWHA was further estimated by network scale-up method. Results: A total of 3 907 subjects, including 1 912 (48.9%) males and 1 995 (51.1%) females, were finally interviewed, and the mean age of the subjects was (40.54±11.69). The average social network size of studied subjects from Minhang district was 206. After the adjustment of backward method, it turned out to be 240. Based on the estimation of network scale-up method and attitude adjustment, the population size of PLWHA was 368 (95%CI: 291.19-444.17), which accounted for 0.03% of the total residents of Minhang district. Conclusion: The process of estimation of PLWHA population based on network scale-up method was relatively simple, but the results need adjustment appropriately.
