HIV/AIDS epidemic and high-risky behaviors among youth in Nanning during 2010-2015

目的了解南宁市青年学生艾滋病疫情及高危行为情况,为针对学校学生开展艾滋病防治工作提供科学依据。方法利用艾滋病综合防治信息系统资料和哨点监测资料,分析2010—2015年南宁市15岁以上学生艾滋病疫情特征及青年学生艾滋病高危行为。结果 2010—2015年南宁市共报告感染艾滋病的15岁以上学生126例,男生120例,女生6例。传播途径均为性传播,其中同性性传播占68.25%,异性传播占31.75%。2010—2015年青年学生发生过性行为的比例男生高于女生(χ~2=51.91,P<0.01);最近1年有配偶或同居的异性性伴的比例男生高于女生(χ~2=19.37,P<0.01)。2010—2015年青年学生最近1年与临时性伴发生过性行为的比例,女生有增高趋势(χ~2=5.81,P<0.05),男生差异无统计学意义。2010—2015年男生中约有1.2%有过同性肛交性行为,2015年男生发生过肛交性行为的比例高于2010—2014年(χ~2=11.14,P<0.01)。商业性行为男性比例高于女性(χ~2=6.51,P<0.05)。最近1年接受过有关预防艾滋病宣传服务的比例,2014—2015年青年学生明显高于2010—2013年(χ~2=380.05,P<0.01)。2010—2015年青年学生最近1年做过艾滋病检测的比例差异无统计学意义(χ~2=3.78,P>0.05)。结论南宁市学生艾滋病感染人数逐年增加,同性性行为是学生感染HIV的主要途径,临时性行为、商业性行为普遍存在,HIV检测率低。建议加强宣传干预,提高高危人群的检测意识。

Objective To investigate HIV/AIDS epidemic and high-risky behaviors among youth in Nanning during 2010-2015 and to provide scientific evidence for HIV/AIDS prevention and control.Methods Data from National HIV Prevention and Treatment Information System were used to analyze HIV/AIDS epidemic among students aged15 years.High-risky behaviors and associated factors were collected through the sentinel surveillance data during 2010-2015.Results A total of 126 students aged15 years had been reported as HIV/AIDS cases,of which 120 cases being male and 6 cases being female.All of the infection were sexually transmitted,including 68.25% reported homosexually transmission and 31.75% hetero sexual.More male youth reported having had sex（χ~2=51.91,P〈0.01） or had a spouse or heterosexual sex partner（χ~2=51.91,P〈0.01）,compared to female youth.During 2010-2015,the increasing trend in one-time hook up within 1 year was found among female students（χ~2=5.81,P〈0.05）.Nearly 1.2% male youth reported anal intercourse.Rate of anal intercourse was significantly higher in 2015 compared to 2011-2015（χ~2=11.14,P〈0.01）.Commercial sex was more common among males（χ~2=6.51,P〈0.05）.More students reported having received HIV/AIDS related education during 2014-2015 compared to 2010-2013（χ~2=380.05,P〈0.01）.No differences were found in HIV/AIDS testing among youth by year（χ~2=3.78,P〈0.05）.Conclusion The number of youth infected with HIV/AIDS shows increasing trend during 2010-2015.Homosexuality might be the leading cause.One-time hook up,commercial sex and low HIV testing remains common among youth in Nanning.The present study calls for comprehensive HIV/AIDS prevention measures and HIV testing awareness among high-risk young people.
