Abstract: Epidemics of HIV among men who have sex with men (MSM) are major public health concerns in most parts of China. This study examined the trends in HIV incidence and associated factors among MSM in Jiangsu Province. Five consecutive cross-sectional surveys were conducted among MSM from 2011 to 2015 in eight cities throughout Jiangsu Province. Participants were recruited from MSM venues or via the internet. Demographic and behavioral data were collected through HIV bio-behavioral surveys. Blood specimens were collected to test for HIV and syphilis. HIV incidence was estimated by the IgG-capture BED-EIA (BED) method and a chi-square trend test was used to compare differences over the years. Multivariate logistic regression analysis was used to identify factors associated with recent infection. A total of 2433, 2678, 2591, 2610 and 2541 participants were enrolled in 2011, 2012, 2013, 2014 and 2015, respectively. HIV incidence increased from 5.10% in 2011 to 6.62% in 2015 ( p = 0.025). MSM who had an education level of junior high school or less (aOR = 1.472, p = 0.018), engaged in condomless anal sex in the past 6 months (aOR = 2.389, p < 0.001), did not have an HIV test in the past 12 months (aOR = 3.215, p < 0.001), and were currently infected with syphilis (aOR = 2.025, p = 0.001) were likely to be recently infected with HIV. HIV incidence is increasing among MSM in Jiangsu Province, China. Condom usage and HIV testing promotion should be prioritized when attempting to reduce HIV transmission among MSM in China.
