目的了解天津市低档场所女性性服务者(FSW)人类免疫缺陷病毒(HIV)、梅毒螺旋体(TP)、丙型肝炎病毒(HCV)的流行现状及影响因素。方法 2013—2014年每年的4—6月对天津市3个区县采用分层多阶段整群抽样方法,对低档场所FSW进行问卷调查和血清学检测。结果共监测1 377人,平均年龄为(33.20±8.755)岁,艾滋病知识知晓率为60.7%(836/1 377),最近1个月与客人发生性行为时每次均使用安全套的比例为81.4%(1 121/1 377),最近1年接受检测比例仅为27.3%(295/1 081);HIV、TP和HCV阳性检出率分别为0.1%(2例)、7.6%(104例)和1.4%(19例)。汉族(OR=0.261,95%CI=0.141~0.486)与最近1个月与客人发生性行为时每次均使用安全套(OR=0.491,95%CI=0.314~0.769)为FSW感染TP的保护因素,最近1年被诊断患过性病(OR=8.120,95%CI=2.815~23.423)为感染TP的危险因素。结论天津市低档场所FSW接受HIV检测的比例较低,艾滋病知识知晓率低,感染性病艾滋病的风险较大。
Objective To investigate the prevalence and influencing factors of human immunodeficiency virus (HIV), treponema pallidum (TP) and hepatitis C virus (HCV) in low-grade female FSWs in Tianjin. METHODS: From April to June of each year in 2013-2014, stratified and multistage cluster sampling was applied to 3 districts and counties in Tianjin to conduct questionnaire survey and serological test on low-grade FSW. Results A total of 1 377 individuals were monitored, with an average age of (33.20 ± 8.755) years. The awareness rate of AIDS was 60.7% (836/1 377). The proportion of condom users who used to have sex with their guests during the recent 1 month was 81.4 The positive rate of HIV, TP and HCV were 0.1% (2 cases), 7.6% (104 cases) And 1.4% (19 cases). Condom use (OR = 0.491, 95% CI = 0.314-0.769) was the protective factor for TP in TPW in the Han nationality (OR = 0.261, 95% CI = 0.141-0.486) , The most recent 1 year was diagnosed with STD (OR = 8.120, 95% CI = 2.815 ~ 23.423) as a risk factor for TP infection. Conclusion The proportion of FSW receiving HIV test in low-grade places in Tianjin is low, the awareness rate of AIDS knowledge is low, and the risk of contracting STD and AIDS is high.
