2012-2015年广西男性流动人员艾滋病哨点监测结果分析

Analysis of HIV sentinel surveillance data on male floating population in Guangxi,2012-2015

目的通过对2012-2015年广西男性流动人员艾滋病哨点监测结果的分析,了解该群体的行为特征及艾滋病流行趋势,为制定相应干预对策提供重要依据。方法根据《全国艾滋病哨点监测实施方案》要求,对广西男性流动人员进行相关的问卷调查和血清学检测工作。结果 2012-2015年各年纳入监测对象分别为800人、800人、806人、800人,2015年艾滋病知识知晓率为99.0%,2012年为83.9%;各年知晓率的差异有统计学意义(χ2=178.272,P<0.05),且呈上升趋势(χ2=147.159,P<0.05)。最近1年发生商业性行为安全套坚持使用率,以及最近一次发生商业性行为安全套使用率的差异有统计学意义(χ2=14.895,P<0.05;χ2=9.85,P<0.05);最近1年发生临时性行为安全套坚持使用率的差异有统计学意义(χ2=18.746,P<0.05)。各年HIV阳性率分别为0.5%、0、0.5%、0.3%,差异无统计学意义(P>0.05);各年梅毒阳性率分别为1.8%、1.3%、0.2%和1.0%,差异有统计学意义(χ2=8.996,P<0.05)。结论广西男性流动人员的艾滋病相关知识知晓率、不安全性行为中安全套使用率等指标有逐年上升趋势,应继续加强对该人群的艾滋病及梅毒等相关性传播疾病的监测,并针对男性流动人员的特点和其对艾滋病知识不够了解部分进行宣传教育,实施更加切实有效的防治措施。

Objective To understand the HIV infection status and related behavioral characteristics among floating population in Guangxi, from 2012-2015, and provide the scientific evidence for developing prevention and control strategies. Methods According to the requirements of the ＂national HIV sentinel surveillance implementation protocol＂, questionnaire surveys were conducted among male floating population in Guangxi, from 2012-2015; and their blood samples were collected for serological detection. Results A total of 3206 subjects was recruited. 800, 800, 806, and 800 male targeted people were surveyed each year, respectively. Among them, the awareness rate of AIDS related knowledge was 93.57 %, with the highest rate （99 % ） in 2015, and the lowest （83.9 %） in 2012, and there was statistically significant difference in annual awareness rate （χ2 = 178. 272, P〈0. 05）. The differences of consistent condom use rate at each commercial sex and the condom use rate at the latest commercial sex were statistically significant （χ2 = 14. 895, P〈0.05 ; χ2 = 9.85, P〈0.05）, respectively. The differences of the consistent condom use rate at each temporary sexual behavior was statistically significant （χ2= 18. 746, P〈0. 05）. The HIV positive rate was 0.5 %, 0, 0.5 % and 0.3 % respectively with no statistical differences （P〉0. 05） and the syphilis prevalence was 1.8%, 1.3%, 0.2% and 1.0% respectively, with the differences statistically significant （χ2 =8. 996 ,P 〈0.05）. Conclusion The total awareness rate of AIDS related knowledge and condom use in unprotected sex have been improved among the male floating population in Guangxi. It is essential to enhance the surveillance of AIDS and syphilis to be infected by sexual transmission and to carry out the HIV/AIDS publicity and education among male floating population according to their characteristics, and more availability and comprehensive prevention and control measures should be taken.
