Abstract:
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 APP were 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 13 174 [95% CI: 9,672~16,676] 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.
