Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact preprints@lancet.com.

Abstract

Background: HIV testing promotion is a critical HIV prevention strategy targeting young men who have sex with men. Understanding young people's social networking characteristics could inform HIV testing strategy.

Methods: We established a longitudinal study of college MSM as users of the Yiyou App, an HIV sero-status query software popular in China. In northeast China (include Heilongjiang province, Jilin province, and Liaoning province) from April 2017 to June 2018, we secured the consented users' social contacts (cross-sectional data) and HIV testing frequency information (longitudinal data), reported by offline HIV testing service dispensary sites. We used multivariable logistic regression and generalized estimated equations to assess predictors of frequency of HIV testing. We visualized the cross-sectional social networking information using Gephi® software.

Findings: We enrolled 752 college MSM and their 390 social contacts into the study. High HIV testing-frequency was more likely among men with recreational drug use (past 6 months, aOR=1.65, 95%CI: 1.00-2.71), having >1 HIV self-test (past 6 months, aOR=2.07, 95%CI: 1.43-3.00) and >1 degree of social contact (aOR=4.58, 95%CI: 3.01-6.97). In the longitudinal analysis, from a cumulative 1299 HIV tests, men having >2 HIV tests were more likely in the past six months to report anal sex (aOR=1.75, 95%CI: 1.37-2.24), recreational drug use (aOR=1.67, 95%CI: 1.24-2.24), and having an HIV self-test (aOR=1.3, 95%CI: 1.02-1.65).

Interpretation: Active social media contacts, recreational drug use, and prior HIV self-test experience predicted more frequent HIV testing among college MSM, suggesting a potential utility of using online social mobile application to deliver tailored interventions.

Funding Statement: Dr Hu is supported in part by National Natural Science Foundation of China (81673232). Dr. Vermund is supported in part by the Yale Center for Interdisciplinary Research on AIDS supported by NIH grant (P30MH062294).

Declaration of Interests: The authors stated: "None."

Ethics Approval Statement: The study was approved by Capital Medical University Ethics Review Board (2016SY15). The study protocol, contents, and procedure were explained before survey conception. Written informed consent was obtained before HIV testing. Social contact information was secured from consented participants. The behavioral surveys were conducted in the local testing service dispensary sites. Prior to data transfer for analysis, all the identifiable data from the App were de-identified in a procedure that was performed per the study protocol.
