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 understand the HIV / AIDS epidemic situation and high-risk behaviors of young students in Nanning and to provide a scientific basis for AIDS prevention and control among school students. Methods Using information of AIDS prevention and control system and sentinel surveillance data, we analyzed the characteristics of HIV / AIDS among students over the age of 15 in 2010-2015 and HIV / AIDS risk among young students. Results From 2010 to 2015, Nanning City reported a total of 126 HIV / AIDS patients over 15 years old, including 120 boys and 6 girls. Transmission routes are sexually transmitted, of which 68.25% of homosexual transmission, accounting for 31.75% of heterosexual transmission. The proportion of male students who had sexual intercourse during 2010-2015 was higher than that of female students (χ ~ 2 = 51.91, P <0.01). The percentage of boys with heterosexual partners who had spouses or cohabitation in recent years was higher than that of girls (χ ~ 2 = 19.37, P <0.01). The proportion of young students who had sexual intercourse with adolescent for the most recent year from 2010 to 2015 showed an increasing tendency (χ ~ 2 = 5.81, P <0.05). There was no significant difference between boys and girls. About 1.2% of male boys in 2010-2015 had homosexual anal sex. The prevalence of anal sex in boys in 2015-2015 was higher than that in 2010-2014 (χ ~ 2 = 11.14, P <0.01). The male sex ratio of commercial sex was higher than that of female (χ ~ 2 = 6.51, P <0.05). The proportion of young people receiving AIDS prevention services in the past year was significantly higher than that of 2010-2013 (χ ~ 2 = 380.05, P <0.01) in 2014-2015. There was no significant difference in the proportion of HIV / AIDS among young students in 2010-2015 (χ ~ 2 = 3.78, P> 0.05). Conclusions The number of HIV / AIDS patients in Nanning City increased year by year. Homosexual behaviors were the main ways of HIV infection among students. Temporary behaviors, commercial behaviors were common and HIV detection rate was low. Proposed to step up publicity and intervention to improve the detection of high-risk groups.
