2010-2015年吉林省暗娼人群艾滋病哨点监测结果分析

目的 分析2010-2015年吉林省暗娼人群艾滋病哨点监测数据,为制定暗娼人群艾滋病相关防控策略提供依据。 方法 2010-2015年,采用分层随机抽样的方法,每个监测点抽取吉林省暗娼不少于400人,进行艾滋病知识知晓及性行为方面的问卷调查,同时采集血样进行梅毒、HIV和HCV检测。 结果 2010-2015年,吉林省共调查暗娼35 830人。该人群艾滋病相关知识的总知晓率为94.4%,并且从2010年的93.0%上升到2015年的95.3%(χ²_趋势=43.756,P＜0.001);最近一次商业性行为安全套使用率为94.5%,并且从2010年的92.6%上升到2015年的95.8%(χ²_趋势=246.304,P＜0.001);最近1个月,商业性行为坚持使用安全套的比例为84.2%,并且从2010年的78.6%上升到2015年的87.9%(χ²_趋势=247.433,P＜0.001)。HIV抗体总的阳性率为0.01%,各年差异无统计学意义(χ²=4.958,P=0.421);梅毒抗体总的阳性率为1.7%,并且从2010年的1.4%上升到2015年的2.6%(χ²_趋势=66.071,P＜0.001)。 结论 吉林省暗娼人群HIV抗体阳性率较低,但梅毒抗体阳性率相对较高且呈逐年上升趋势。应该加强针对暗娼人群的行为干预服务,进一步提高该人群坚持使用安全套的比例,并促进其定期检测HIV和梅毒。

Results of sentinel surveillance of AIDS among female sex workers in Jilin Province, 2010-2015

Objective To analyze the data of sentinel surveillance of AIDS among female sex workers (FSWs) in Jilin Province from 2010 to 2015, and to provide a basis for formulating strategies on HIV/AIDS control and prevention in FSWs. Methods A stratified random sampling method was used to select more than 400 FSWs in each surveillance site in Jilin Province from 2010 to 2015. A questionnaire survey was conducted to investigate their awareness of AIDS-related knowledge and sexual behavior, and blood samples were simultaneously collected for testing the antibodies against syphilis, HIV and HCV. Results A total of 35,830 FSWs in Jilin Province were surveyed during 2010-2015. The overall awareness rate of AIDS-related knowledge among the FSWs was 94.4%, increasing from 93.0% in 2010 to 95.3% in 2015 (χ²_trend=43.756, P<0.001). The rate of condom use in the last commercial sexual behavior was 94.5%, increasing from 92.6% in 2010 to 95.8% in 2015 (χ²_trend =246.304, P<0.001). The proportion of consistently using condom during commercial sexual behavior in the last month was 84.2%, increasing from 78.6% in 2010 to 87.9% in 2015 (χ²_trend=247.433, P<0.001). The overall HIV-antibody positive rate was 0.01%, showing no statistically significant difference among the 6 years (χ²=4.958, P=0.421). The overall syphilis-antibody positive rate was 1.7%, increasing from 1.4% in 2010 to 2.6% in 2015 (χ²_trend=66.071, P＜0.001). Conclusions The positive rates of HIV antibody in the FSWs in Jilin Province during 2010-2015 were low, whereas the positive rates of syphilis antibody were relatively high and showed an increasing tendency year by year. It is necessary to enhance the targeted behavioral intervention service among the FSWs, improve the proportion of consistent condom use and promote regular testing for HIV and syphilis.
