摘　　要：目的了解2011—2020年广州市学生人群的艾滋病疫情及相关行为变化情况,为加强学生人群艾滋病防控提供参考依据。方法利用艾滋病综合防治信息系统收集、分析2011—2020年广州市学生人群艾滋病疫情特征;利用学生哨点监测数据分析艾滋病相关行为及影响因素。结果 2011—2020年广州市共新报告学生艾滋病病例638例,学生病例报告数呈增长趋势(APC=17.80,P<0.05);男性98.43%;平均年龄(20.45±2.64)岁;大专及以上学历83.70%;检测咨询的病例52.35%;性途径传播99.06%,其中同性传播83.86%;未婚98.28%;HIV占比逐年升高(χ趋势2=7.357,P<0.01)。哨点监测在2014—2016年检出的HIV抗体阳性检出率分别为0.20%、0.12%和0.09%;2017和2020年的梅毒螺旋体抗体阳性检出率分别为0.15%和0.12%。性行为发生率13.57%,第一次性行为平均年龄(19.85±1.96)岁,性行为年龄有提前趋势(χ趋势2=62.168,P<0.01)。接受防艾宣传服务的比例、参与防艾宣传服务的比例、与固定性伴每次使用安全套的比例和接受HIV检测的比例均有升高趋势(χ趋势2=7.532、10.327、8.375、26.659,P<0.01)。相对未接受干预服务的学生,接受干预服务的学生主动参与干预服务的比例、接受HIV检测的比例均有升高趋势(χ^(2)=145.667、5.994,P<0.05)。多因素Logistic回归结果显示发生性行为、低年级、广东省户籍、曾参与过艾滋病干预服务的学生接受HIV检测率更高(P<0.01)。结论 2011—2020年广州市学生接受防艾宣传服务、参与防艾宣传服务、与固定性伴每次使用安全套和接受HIV检测等相关安全行为有逐年增长趋势,提示接受干预服务可以促进学生接受HIV检测和使用安全套等安全行为。疫情快速增长趋势得到遏制,进入平稳状态。Objective To understand AIDS epidemic and related changes in behaviors among student populations in Guangzhou from 2011 to 2020,and to provide reference for strengthening AIDS prevention and control among student populations.Methods The characteristics of AIDS epidemic among student populations in Guangzhou from 2011 to 2020 were collected and analyzed by means of comprehensive AIDS prevention and control information system, and related behaviors and influencing factors of AIDS were analyzed by virtue of sentinel surveillance data.Results A total of 638 AIDS cases were newly reported among students in Guangzhou from 2011 to 2020,and the number of reported cases showed increasing trend(APC=17.80,P<0.05);98.43% cases were males;the cases were featured with average age of(20.45±2.64)years;83.70% of them were junior college graduates or above;52.35% of the cases received counseling, 99.06% of cases were sexually transmitted, 83.86% of cases were homosexual, 98.28% of cases are unmarried, and the proportion of HIV increased annually(χtrend2=7.357,P<0.01).Sentinel surveillance showed that the positive rate of detected HIV antibodies were 0.20%,0.12% and 0.09% from 2014 to 2016 respectively, and the positive rate of detected Treponema Pallidum antibodies was 0.15% and 0.12% in 2017 and 2020 respectively, the incidence rate of sexual behavior was 13.57%,the mean age of first sexual behavior was(19.85±1.96)years, and the age of sexual behavior showed the tendency of earlier intercourse(χtrend2=62.168,P<0.01).The rate of receiving HIV/AIDS avoidance publicity service, rate of participating in HIV/AIDS promotion service, rate of using condom with fixed sex partners and rate of receiving HIV tests all had an upward(χtrend2=7.532,10.327,8.375,26.659,P<0.01).Compared to students who did not receive intervention services, the proportion of the students receiving intervention service actively participating in intervention services, proportion of students receiving HIV testing showed elevating proportion(χ^(2)=145.667,5.994
