title: [Infection status of HIV in men who have sex with men in Nanjing, 2011-2015].
abstract: Objective:To understand the current status of HIV infection in men who have sex with men (MSM) in Nanjing, explore the associated factors with HIV infection, and provide information for the intervention in MSM.Methods:Data collected in the consecutive sentinel surveillances among MSM during 2011-2015 includes MSM's social-demographic information, sexual behavior histories, access to HIV prevention services and HIV testing in the past year. The infection trend was analyzed withχ2test and the factors associated with HIV infection were identified through multivariate logistic regression analysis.Results:From 2011 to 2015, 712, 670, 656, 681 and 601 MSM were surveyed respectively. The HIV infection rates were 7.4%, 13.7%, 9.8%, 12.0% and 12.0% respectively, with an increasing trend (P=0.044). Syphilis prevalence rates were 9.1%, 11.5%, 6.0%, 10.6% and 5.8% respectively, with a decreasing trend (P=0.042). From 2011 to 2015, the percentage of MSM who failed to consistently use condoms for anal sex in the past 6 months increased significantly from 46.4%(260/560) to 55.7%(257/461) the percentage of those having commercial sex with males increased significantly from 1.2%(8/692) to 3.0%(18/593) in 2015, while the percentage of those receiving HIV test in the past year decreased significantly from 67.7%(482/712) to 57.6%(346/601). Those who were aged >25 years, lived in Nanjing for less than 2 years, had a high school or below educational level, failed to consistently use condoms at anal sex in the past 6 months, failed to have HIV test in the past year and were infected with syphilis had higher risk for HIV infection.Conclusion:Given the increasing trend of HIV infection and high risk sexual behavior in MSM in Nanjing, it is necessary to strengthen the comprehensive HIV prevention and intervention through expanding HIV test coverage and promoting condom use to curb HIV epidemic in MSM.
