北京市石景山区暗娼和嫖客人群艾滋病相关知识和危险行为

目的了解石景山区暗娼（CSW）和嫖客人群艾滋病相关知识、危险行为以及艾滋病感染状况，为有针对性地开展干预工作提供依据。方法采用标准化问卷，匿名收集2010—2011年石景山区拘留所收押的暗娼和嫖客人群的信息，包括一般人口学特征、艾滋病相关知识知晓情况及艾滋病相关高危行为等，同时采集5mL静脉血检测艾滋病病毒（HIV）和梅毒皿清抗体。结果197名暗娼中检出1例HIV抗体阳性者，182名嫖客中未检出HIV抗体阳性者。暗娼梅毒抗体及梅毒快速血浆反应素（RPR）试验阳性率分别为8．1％和4．6％；嫖客梅毒抗体及梅毒RPR试验阳性率分别为6．6％和3．8％，暗娼和嫖客人群HIV和梅毒感染水平差异无统计学意义（P〉0．05）。暗娼和嫖客人群艾滋病知识知晓率分别为84．3％和89．0％，二者差异无统计学意义（x^2=1．831，P=0．176）。暗娼和嫖客自报最后一次商业性行为安全套使用率分别为83．2％和84．1％，二者差异无统计学意义（x^2=0．046，P=0．830）。暗娼最近一年接受过艾滋病干预服务的比例为45．7％，高于嫖客的22．5％（x^2=2．431，P=0．000）。暗娼最近一年做过HIV抗体检测的比例为35％，高于嫖客的11．5％（x^2=28．820，P=0．000）。结论暗娼和嫖客人群HIV感染较低，梅毒感染相对较高，传播风险不容忽视；今后应有针对性地开展艾滋病预防干预服务，扩大暗娼和嫖客人群的HIV抗体检测覆盖面。

Commercial sex workers and their clients on AIDS-related knowledge and risk behaviors in Shijingshan District, Beijing

Objective To understand acquired Immunodeficiency Syndrome （AIDS）-related knowledge, risk be- haviors and HIV infection status among commercial sex workers （CSW） and their clients in Shijingshan District, and provide the basis for targeted interventions. Methods Standardized questionnaires were used to gather informa- tion from 2010 to 2011 on general demographic characteristics, AIDS-related knowledge and risk behaviors of com- mercial sex workers and their clients from a detention center in Shijingshan District, and 5mL venous blood samples were collected to test antibodies of HIV and syphilis. Results One positive HIV antibody was detected in 197 com- mercial sex workers tested, while no HIV cases were found in 182 clients tested. The positive rate of syphilis anti- bodies in commercial sex workers was 8.1%, and the positive rate of syphilis rapid plasma reagin （RPR） of those tested was 4.6 %, while positive rates of their clients were 6.6 % and 3.8 %, respectively. The difference of HIV and syphilis infection between commercial sex workers and their clients was not statistically significant （P〉0.05）. Knowledge rate about the AIDS rate of commercial sex workers was 84. 3 %, and that of their clients was found to be 89.0%, so the difference of knowledge rate between the two groups was not statistically significant （x^2 = 1. 831, P=0. 176）. Condom-use rate of commercial sex workers at the last time of commercial sex behaviors was found to be 83.2% and their clients at 84.1%, the difference was not statistically significant （x^2 = 0. 046, P = 0. 830）. The proportion of AIDS intervention services that commercial sex workers were provided （45.7 %） was higher than that of their clients （22.5%）. （x^2= 22. 431, P〈 0. 000）. The proportion of HIV antibody testing among female sex workers （35.0Y0） was higher than that of their clients （11.5%）, （x^2 = 28. 820, P=0. 000）. Conclusion The level of HIV infection among commercial sex workers and their clients was found to be low, with relatively high levels of syphilis infection. The risk of transmission cannot be ignored, therefore targeted AIDS prevention and intervention services should be carried out among commercial sex workers and their clients, and the coverage of HIV antibody testing should be expanded among them also.
