Factors Associated with First-Time HIV Testing Among MSM via Secondary Distribution of HIV Self-test Kits in Zhuhai, China

Abstract

HIV self-testing (HIVST) is an effective method to expand HIV testing coverage worldwide. We analyze the results of HIVST and sexual behaviors of first-time testers among Men who have sex with men (MSM) who participated in a secondary distribution of HIVST kits. A total of 589 participants were recruited, including 173 first-time testers and 416 non-first-time testers. The first-time testers were mainly of Han ethnicity (aOR 1.88, 95% CI 1.10, 3.24), more likely to be HIV positive (aOR 7.18, 95% CI 2.37, 21.72), and had higher income (aOR 2.01, 95% CI 1.10, 3.69). Both groups were less likely to have anal sex with male partners (χ²: 146.24, P < 0.01), (χ²: 582.72, P < 0.01) or have sex with female partners (χ²: 19.01, P < 0.01), (χ²: 35.74, P < 0.01) after HIVST. We should expand HIVST among MSM and other key populations to identify first-time testers.
