应用新媒体技术估计上海浦东新区男男性行为者规模的初步研究

Size estimation of MSM population in Pudong New Area usingnew media technology

目的探讨运用新媒体技术,对浦东新区男男性行为者(MSM)网络人群规模进行估计,了解新媒体软件使用频率、HIV检测及高危行为调查,为艾滋病防制工作提供依据。方法利用同志交友软件获取在浦东新区内的网络MSM人群注册信息,于2019年3月28日和4月11日这两天五个时间点,分别对登陆同志交友软件的MSM展开计数,通过比对登录名和注册信息,确定被计入的MSM,采用捕获-再捕获法计算网络MSM人群规模。同时对在线MSM进行问卷调查。结果浦东新区当地MSM网络人群规模约为13174(95%CI:9672~16676)。多性伴比例占72.5%。经有序多分类logistics分析,年龄、文化程度、是否听过艾滋病的讲座、是否在VCT门诊接受过艾滋病的宣传教育是艾滋病了解程度的影响因素。结论新媒体技术为估计MSM人群规模提供了新的技术手段,MSM人群防范艾滋病风险意识仍需加强,在网络信息化时代,新媒体技术在艾滋病健康宣传教育工作中的作用值得进一步研究。

Objective To explore the use of new media technology to estimate the size of the online MSM population in Pudong New Area,to understand the frequency of new media software use,HIV testing and high-risk behavior,and to provide a basis for AIDS prevention and control.Methods The online MSM registration information in Pudong New Area was collected through a gay dating APP.At five time points on March 28 and April 11,2019,MSM who logged into the gay dating APPwere counted.The MSM were confirmed by comparing the login name and registration information.The capture-recapture(C-R)method was used to calculate the MSM population size.Meanwhile,a questionnaire survey was conducted on the online MSM.Results The MSM population size in Pudong New Area was estimated at 13174[95%CI:9672~16676]through the C-R method.The proportion of multiple sexual partners accounted for 72.5%.According to the ordered multi-classification logistics analysis,age,education level,experience of attending a talk on AIDS,and experience of receiving AIDS publicity and education in the VCT clinic were the influencing factors of AIDS awareness.Conclusion New media technology provided new technical means for estimating the size of MSM population.The MSM population′s awareness of AIDS risk and prevention still needs to be strengthened.It is worthy of further studies on the role of new media technology in AIDS prevention and health education in the future.
