HIV infection status and related factors in men who have sex with men in sentinel surveillance in Shanxi province, 2010, 2015 and 2020

Objective To understand the infection status of HIV and related factors in men who have sex with men (MSM) in Shanxi province in 2010, 2015 and 2020. Methods According to the sentinel surveillance protocol, continuous cross-sectional survey were conducted to collect the information about basic characteristics, general demographic characteristics, AIDS knowledge awareness, high-risk sexual behavior, sexually transmitted diseases, intervention services and HIV infection rate of the MSM in Shanxi in 2010, 2015 and 2020. Results In 2010, 2015 and 2020, a total of 2 708 MSM were included in this study. There were significant differences in HIV infection rate among three years (χ²=23.76, P<0.001) with an increasing trend with year (trend χ²=17.34, P<0.001). The rates of anal sex, commercial sex and heterosexual behavior in the past 6 months were 77.62% (2 102/2 708), 5.91% (160/2 708) and 28.14% (762/2 708) respectively, and the rates of consistent use of condom were 52.52% (1 104/2 102), 63.13% (101/160) and 23.49%(179/762) respectively, and the rate of consistent condom use was low. Results from multivariate logistic regression analysis showed that different cities, having educational level of junior high school or below, being recruited through internet, voluntary counseling and testing, suffering from sexually transmitted diseases, occasional condom use in anal sex in the past 6 months were the correlative factors of HIV infection of MSM. Conclusions The HIV infection rate of MSM in Shanxi increased year by year from 2010, 2015 to 2020. The HIV/AIDS-related risk behavior persisted, and the proportion of condomuse adherence was low, and the HIV detection rate was low in the MSM, so targeted and effective measures should be taken to promote the condom use adherence and regular HIV testing in MSM.
