Prevalence and Correlates of Point-of-sex Human Immunodeficiency Virus Self-testing Among Human Immunodeficiency Virus-negative Men Who Have Sex With Men in China.

ABSTRACT: BACKGROUND:Human immunodeficiency virus (HIV) self-testing (HIVST) provides a promising tool to screen sex partners for men who have sex with men (MSM) who engage in condomless sex and want to avoid HIV infection. Although previous studies have demonstrated HIVST acceptability and increased testing uptake, limited data exist on its use between sex partners for point-of-sex HIV testing. This study examined prevalence and correlates of point-of-sex HIVST among Chinese MSM. METHODS:A cross-sectional survey was conducted among 400 HIV-negative Chinese MSM in 2017. Participants were recruited through a multifaceted sampling approach and self-administered an electronic questionnaire. Point-of-sex HIVST was measured by asking participants if they had ever conducted HIVST with a sex partner before sex to ensure that they both knew their HIV statuses. Multivariable logistic regression was used to identify correlates of point-of-sex HIVST after controlling for age, education and sexual orientation. RESULTS:Overall, 19.2% (77/400) men reported point-of-sex HIVST (51.3% among self-testers). Participants who had four or more HIV self-tests before had 7.57-fold greater odds (95% confidence interval, 3.75, 15.28) of reporting point-of-sex HIVST compared to those who had fewer HIVST experiences. Point-of-sex HIVST was otherwise not associated with most other socio-demographic or behavioral practices, suggesting that it may be broadly acceptable. CONCLUSIONS:A substantial proportion of Chinese MSM had utilized HIVST with their partners before sex, especially among those who were more experienced with HIVST. Scale up and routine implementation of HIVST programs are further warranted to facilitate point-of-sex HIV testing.
