| 目的 了解南京市男男性行为人群（MSM）HIV的流行趋势，同时探索HIV感染的相关因素，为制定干预策略提供依据。方法 2011-2015年在南京市连续开展MSM哨点监测，调查该人群社会人口学信息、性行为情况、艾滋病预防服务覆盖和近1年HIV检测情况等，采用趋势χ2检验进行趋势分析及多因素logistic回归进行影响因素分析。结果 2011-2015年分别调查了712、670、656、681和601名MSM，HIV感染率分别为7.4%、13.7%、9.8%、12.0%和12.0%，呈上升趋势（P=0.044）；梅毒感染率分别为9.1%、11.5%、6.0%、10.6%和5.8%，呈下降趋势（P=0.042）；最近6个月与同性肛交时未坚持使用安全套的比例从2011年的46.4%（260/560）上升至2015年的55.7%（257/461）；最近6个月与同性发生商业性行为的比例从2011年的1.2%（8/692）上升至2015年的3.0%（18/593）；最近1年做过HIV检测的比例从2011年的67.7%（482/712）下降至2015年57.6%（346/601），趋势χ2检验均有统计学意义（P<0.05）。>25岁、在本地居住2年以内、大专以下文化程度、最近6个月肛交时未坚持使用安全套、最近1年未做过艾滋病检测和梅毒感染是该人群感染HIV的危险因素。结论 南京市近5年MSM人群HIV感染率和高危性行为呈上升趋势，应继续加强MSM人群HIV动员检测和安全套推广等综合干预措施，以控制HIV疫情的进一步扩散。 |

| 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 with χ2 test 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. |
