| 摘 要： | 目的 估计成都市男男性行为人群（MSM）规模，为预测艾滋病流行趋势和调整防治策略提供科学依据。方法 应用乘数法原理结合MSM手机交友软件进行估计，以连续10 d内在成都地区范围内登录该软件人数的平均值作为记录数（r），通过网络和现场调查了解MSM人群同时期内登录过软件比例的倒数作为乘数（m），r与m相乘即为成都市MSM人群估计数。结果 成都市MSM人群规模为68 258人,高值为115 898人，占全市15～59岁男性人口比例的1.2%～2.0%。结论 以手机交友软件为目标机构的乘数法估计结果基本反映了成都市MSM人群规模。

| Abstract: | Objective The study aimed to estimate the population size of men who have sex with men (MSM) in Chengdu and to provide a basis for predicting the trend and adjusting control strategy for human immunodeficiency virus(HIV) epidemic. Methods Multiplier method and mobile phone MSM social application(App) were used for the estimation. The number of MSM(r) is the average person-times of logging in App in Chengdu region within ten days. Meanwhile, a survey was conducted among MSM to obtain the proportion of MSM who had logging in the APP during the given period, the reciprocal of the proportion was the multiplier(m), therefore, population size can be estimated by r multiplied by m. Results The population size of MSM in Chengdu city was 68258, and the high value was 115898, accounting for 1.2% to 2.0% of local male population aged from 15 to 59 years. Conclusion It is feasible to use multiplier method which selects mobile phone social App as target institution to estimate population size of MSM. |
