贵港市大龄女性性工作者艾滋病相关认知、行为和感染情况分析

Study on HIV related knowledge,behavior and infections among older female sex workers in Guigang

目的:分析2010—2015年贵港市不同年龄段女性性工作者(FSWs)艾滋病(AIDS)相关知识、行为以及AIDS和梅毒感染情况,为贵港市制定有针对性的防治措施和策略提供理论依据。方法:于2010—2015年在贵港市各FSWs哨点抽取调查对象,使用国家AIDS哨点监测FSWs调查问卷进行面对面匿名问卷调查。结果:2010—2015年,贵港市共6 200名FSWs参与调查,≥35岁的大龄FSWs(OFSWs)占44.48%,在OFSWs中,已婚/同居占89.99%,小学文化水平占61.09%,外省户籍占59.32%,低档场所来源占73.79%,均高于<35岁组FSWs,差异均有统计学意义(P<0.001);贵港市FSWs总的人类免疫缺陷病毒(HIV)知晓率为90.65%,除2014年外,<35岁组FSWs的HIV知晓率均高于≥35岁组OFSWs;2010—2013年,<35岁组FSWs的坚持使用安全套率高于≥35岁组OFSWs(P<0.05),2014—2015年,两组安全套使用率比较差异无统计学意义(P>0.05);FSWs总HIV和梅毒感染率分别为1.92%和11.19%;≥35岁组OFSWs的HIV和梅毒感染率均高于<35岁组FSWs,差异有统计学意义(P<0.001)。结论:贵港市≥35岁的OFSWs文化水平、HIV知晓率和坚持使用安全套率较低,而HIV和梅毒的感染率较高。根据不同年龄组FSWs分别采取有针对性的干预措施,可以有效地控制贵港市FSWs中AIDS的感染和传播风险。

Objective:To explore HIV/AIDS awareness,high-risk sexual behavior,HIV and syphilis infection among different age groups in female sex workers(FSWs)in Guigang city during 2010 to 2015,and to provide theoretical data for local AIDS prevention and control.Methods:A questionnaire was conducted in FSWs sentinels in Guigang during 2010-2015.Face to face anonymous questionnaire using“national HIV sentinel surveillance FSW questionnaire”was carried out by trained investigators.Results:Of 6,200 FSW participants,44.48%belonged to older FSWs(OFSWs),namely,those aged 35 years or older.Among OFSWs,89.99%were married or cohabiting,61.09%were at primary school education level,59.32%were from other provinces,and 73.79%worked in the low-end places.All of the above characteristics in OFSWs were significantly different with those in FSWs younger than 35 years old(P<0.001).The average HIV awareness rate among OFSWs was 90.65%.Except in 2014,the awareness rates annually in FSWs<35-year-old group were significantly higher than those in OFSWs.From 2010 to 2013,the consistent condom use rates annually in FSWs<35-year-old group were also significantly higher than those in OFSWs(P<0.05).However,there were no significant difference between two groups in 2014 and 2015,respectively(P>0.05).The overall prevalence of HIV and syphilis in FSWs were 1.92%and 11.19%,respectively.There were significant differences in HIV and syphilis infection rates among different age groups(P<0.001).Conclusion:The education level,HIV awareness,and adherence rate of condom use in OFSWs were lower than those in FSWs who were younger than 35 years old.Correspondingly,the HIV and syphilis infection rates were significantly higher in OFSWs.Due to the fact that different characteristics were shown among different age groups in FSWs in Guigang city,targeted interventions according to different age groups may effectively control HIV infection and transmission in FSWs in Guigang,Guangxi.
