摘　　要：目的分析长沙市男男性接触人群（MsM）HIv感染趋势，为制定控制政策提供依据。方法对2012—2014年MSM人群国家HIV监测哨点资料收集的人口学、艾滋病知识知晓率和行为学以及HIV感染情况进行分析。结果三年监测对象平均年龄（27．4％--28．1岁）、婚姻（未婚占79．8％～82．5％）和文化程度（大专以上占72．7％～75．2％）等人口学情况基本稳定。艾滋病预防知识知晓率为89．5％--92．5％。最近一次和最近六个月与同性发生肛交坚持使用安全套的比例分别是58．7％--69．5％和33．0％--42．2％。监测对象三年中检出HIV抗体阳性分别26例（6．5％）、30例（7．5％）和36例（9．0％），差异无统计学意义（x2=1．789，P〉0．05）。大专以上文化程度（OR：0．46，95％C1：0．295～0．716）和最近一次与同性发生肛交坚持使用安全套（OR：0．567，95％C1：0．366-0．877）感染HⅣ风险低。结论长沙市MSM人群HIV感染率总体处于上升趋势，但上升的幅度比较缓慢，因此应加强对MSM人群HIV监测，尽快明确MSM人群对我国艾滋病流行的影响。Objective To analyze the trends on HIV infection among men who have sex with men （MSM） in Changsha City so as to provide evidence for developing control policy. Methods We analyzed the data on demography, awareness rate of AIDS- related knowledge and behavior and HIV prevalence of MSM in Changsha obtained from the national HIV sentinel sur- veillance database during 2012 - 2014. Results The information about the average age （27.4 - 28.1 years old）, marriage （ the unmarried accounted for 79.8 - 82.5 % ） and educational background （college degree or above accounted for 72.7 - 75.2 % ） among MSM under 3 - year - surveillance was stable. The awareness rates of AIDS prevention knowledge were between 89.5 % and 92.5 %. The rates of consistent condom use during anal intercourse in the last time and in the past 6 months among the MSM remained low （58.7 - 69.5% and 33.0 - 42.2% respectively）. The positive rates of HIV antibody of MSM in 2012, 2013 and 2014 were 6.5% （26/400）, 7.5% （30/400） and 9.0% （36/400） respectively, without statistically significant differ- ence （ X 2 = 1. 789, P 〉 0.05）. The risk of HIV infection was found to be lower among MSM with college degree or above （ OR ： 0.46,95 % CI：O. 295--0. 716）and MSM with consistent condom use during anal intercourse in the last time （OR：O. 567,95 % CI ： 0. 366 -- 0. 877）. Conclusions HIV infection rate of MSM group in Changsha City remains an upward trend as a whole, but the rising range is relatively slow. Therefore, it is necessary to intensify HIV surveillance on MSM group and identify the in- fluence of MSM group on AIDS prevalence as soon as possible.
