目的分析近年来天津市15～24岁青年学生艾滋病疫情状况及相关行为特征。方法收集2006—2011年天津市15～24岁年龄组艾滋病病例报告数据信息和2010—2011年每年4—6月份对河西、津南2区内随机抽取2所大专院校中的在校生开展青年学生哨点监测。每个哨点每年监测样本约为800人。监测内容包括一般人口学信息、行为学信息、艾滋病防治有关信息和血清学信息(HIV、梅毒检测情况)。结果 2006—2011年共报告15～24岁青年学生HIV/AIDS 54例,其中HIV 51例,AIDS 3例,6年间各年青年学生报告病例数占当年报告病例总数的比例分别为2.52%(3/119)、1.92%(3/156)、3.24%(8/247)、4.18%(12/287)、3.15%(11/349)和4.01%(17/424)。同性性传播为主要传播途径,占79.63%(43/54)。来自于专题调查检测出的病例数最多,占38.89%(21/54),其次为无偿献血检测占18.52%(10/54)。2010和2011年天津市青年学生哨点分别监测青年学生1 607和1 608人,监测对象有过性行为者的比例分别为4.17%(67/1 607)和3.61%(58/1 608);最近1年发生过商业性行为者的比例分别为0.12%(2/1 607)和0.06%(1/1 608);最近1年发生过男男性行为者的比例分别为0.25%(2/807)和0.34%(3/886);2010和2011年HIV阳性检出率分别为0.12%(1/1 607)和0.11%(1/1 608);梅毒螺旋体抗体检出率均为0;艾滋病知识总知晓率分别为82.64%(1 328/1 607)和79.98%(1 286/1 608);最近1年接受过干预服务者的比例分别为28.31%(455/1 607)和24.75%(398/1 608)。结论 2006—2011年天津市青年学生的HIV/AIDS报告数有所上升,主要传播途径是同性性传播。应加强对该人群的宣教工作。

Objective To analyze the HIV/AIDS epidemic situation and related behavioral com- ponents among young students aged from 15 to 24 in Tianjin in the past years. Methods Data on age group （15 -24 years old） through case reporting system were collected from 2006 to 2011 and continuous sentinel surveillance data carried out from 2010 to 2011 regarding Tianjin young student sentinel sites were also collected. From April to June each year, student sentinel surveillance was carried out in two universi- ties by using random sampling method in Hexi and Jinnan districts. Self-administered questionnaire survey and blood tests （HIV and syphilis） were performed, The sample size was about 800 cases per site per year. Results from 2006 to 2011, a total of 54 HIV/AIDS cases were reported among the students aged 15 -24 years, including 51cases with HIV antibody positive and 3 AIDS cases. Homosexual transmission （79. 63%, 43/54） was the main route of transmission. The largest number of cases was found from the special subject investigation detection （38. 89% , 21/54）. In the student sentinel surveillance sites, 1 607 and 1 608 students were monitored in 2010 and 2011, respectively. Of them, 4. 17% （67/1 607） and 3.61% （58/1 608） admitted to have had sex behaviors; 0. 12% （2/1 607） and 0. 06% （1/1 608） had commercial sex in the past year; 0. 25% （2/807） and 0. 34% （3/886） conducted MSM in the past year;HIV antibody positive rates were 0. 12% and 0. 11% ; the syphilis antibody positive rate was 0; awareness rates on HIV/AIDS were 82.64% （1 328/1 607） and 79.98% （1 286/1 608） ; 28.31% （455/1 607） and 24. 75% （398/1 608 ） received intervention services in the past year, in 2010 and 2011, respectively. Conclusion In recent years, the HIV/AIDS number through case reporting system on the young students was increasing. The main transmission was homosexual. We should strengthen the education to this group population.
