中国2006--2010年男男性行为者艾滋病疫情分析

目的 分析2006-2010年中国男男性行为者(MSM)的艾滋病疫情特征.方法 分析2006-2010年中国艾滋病病例报告系统中男男性传播病例的三间分布(时间、人群、地区)及哨点监测系统中MSM的HIV抗体检出率及安全套使用率.结果 艾滋病病例报告系统显示,2006-2010年男男性传播病例构成比从1.5％增长到10.8％,是增长最快的传播途径.与其他传播途径相比,男男性传播HIV/AIDS病例具有以下明显的特征:15～29岁为主(54.6％)、文化程度较高(具有高中及以上学历者占69.8％)、未婚为主(64.8％)、干部/教师/医生离退休人员(14.3％)及学生(7.9％)等职业占相当高的比例、流动性强(流动人口占36.2％)、城市为主(城市人口占72.6％)、专题调查(26.7％)及无偿献血(6.4％)检出比例较高.地区分布差异大,主要分布在北京、四川、广东、重庆、江苏、辽宁、上海和浙江等经济发达地区的大中城市.哨点监测系统显示,2006-2010年中国MSM的HIV抗体阳性检出率(中位数)为3.4％,最近一次安全套使用率(中位数)为73.2％.结论2006-2010年中国男男性传播艾滋病报告病例构成比增长快速,哨点监测发现MSM感染率较高,安全套使用率较低,表明MSM艾滋病流行严重且呈明显上升趋势,其中以15～29岁青年学生及无偿献血人员感染为主.

Epidemic characteristics of HIV/AIDS among men who have sex with men from 2006 to 2010 in China

Objective To analyze the epidemic characteristics of HIV/AIDS among men who have sex with men (MSM) from 2006 to 2010 in China,and to provide evidence for the development of prevention and control measures.Methods Through the network reporting information system.The distribution of MSM transmission was analyzed.Through sentinel surveillance system from 2006 to 2010,data was gathered and analyzed for HIV/AIDS positive rates and condom use to describe the epidemic characteristics of HIWAIDS among MSM.Results Data from HIV/AIDS case reporting system showed that the proportion of MSM transmission was on the rise (from 1.5％ in 2006 to 10.8％ in 2010),becoming the fastest growth of spreading.Compared with other routes of spreading,MSM transmission showed the following obvious characteristics: 15 to 29 years olds (54.6％),having higher culture background (senior high school graduattesed or above accounting for 69.8％),unmarried (64.8％),being cadres/teacher/doctor/retirees and students (accounted for 14.3％ and 7.9％),with high mobilityfloating population (36.2％),being urban population (72.6％),having history of blood donation without payment (26.7％ and 6.4％ ).In terms of location,they mainly lived in provinces as Beijing,Sichuan,Guangdong,Chongqing,Jiangsu,Zhejiang,Shanghai and Liaoning where economics were more developed.Data from HIV/AIDS sentinel surveillance system showed that,from 2006 to 2010,the HIV positive anti-body detection rate (median) was 3.4％ among MSM in this country,much higher than among the female sex workers.Rate on condom usage (median) was 73.2％,lower than among the female sex workers.Conclusion The proportion of HIV transmission among MSM was on the rapid rise from 2006 to 2010 in China.Through HIV/AIDS sentinel surveillance system,we found that the infection rate was high but the rate of condom usage was low among MSM.Factors as being 15 to 29 years olds,students and blood donors shold be under major concern.
