title: HIV Testing and Awareness of Partner's HIV Status Among Chinese Men Who Have Sex with Men in Main Partnerships.
abstract: Many men who have sex with men (MSM) do not use condoms with their main partners, especially if both parties are of the same HIV status. However, significant proportions of MSM have never tested or recently tested and are unaware of their main partners' HIV status. A cross-sectional survey was conducted among 524 MSM in Jiangsu, China in 2013-2014. Time-location sampling and online convenience sampling were used to recruit participants. We compared awareness of HIV status and recent HIV testing between participants who had main partners versus those who did not, and identified factors associated with recent HIV testing among men in main partnerships. Participants in main partnerships were significantly more likely to report recent HIV testing and being HIV-negative instead of HIV-unknown compared to participants in casual partnerships only. Overall, 74.5 % of participants were aware of their main partners' HIV status. Among participants in main partnerships, those who had 2-5 male anal sex partners in the past 6 months and those who reported that their partners were HIV-negative had 2.36 (95 % CI 1.12, 4.97) and 4.20 (95 % CI 2.03, 8.70) fold greater odds of being tested in the past year compared to those who had main partners only and those whose partners were HIV-positive/unknown, respectively. Chinese MSM in main partnerships might be practicing serosorting and may be at lower risk for HIV infection due to increased awareness of main partners' HIV status and higher uptake of recent testing.
