目的了解深圳市向女性提供性服务的男性性工作者(MSW)的艾滋病相关知识知晓率、行为及艾滋病病毒(HIV)/梅毒感染状况,探索适合该人群的艾滋病宣传教育和行为干预措施。方法通过以场所为基础的抽样方法,对深圳市MSW进行问卷调查,并抽血检测其HIV/梅毒感染状况。结果本次调查206名MSW,平均年龄(24.1±3.98)岁,HIV阳性率1.5%(3人),梅毒阳性率2.9%(6人)。外省户籍占85.4%(176人);自我性取向评价为异性恋占87.9%(181例)。与女性客人发生无保护性行为的占49.5%(102人);最近一次与女性客人发生性行为的安全套使用率为85.9%(177人);艾滋病知识知晓率为57.3%(118人)。自我性取向评价、与女性客人发生无保护性行为、最近一次与女性客人安全套使用情况,与HIV/梅毒感染有关(P<0.05)。多因素分析显示,自我性取向评价为同性恋[比值比(OR)=53.604]、与女性客人有无保护性行为(OR=13.185)是MSW HIV/梅毒感染的危险因素。结论深圳市MSW的流动性大,HIV、梅毒感染率低,艾滋病知识知晓率低,无保护商业性行为发生率高,应加强宣传教育及行为干预,提高安全套使用率。
Objective To understand the AIDS-related knowledge, behavior and HIV / syphilis among male sex workers (MSW) who provide sexual services to women in Shenzhen and to explore AIDS publicity and education and behavioral interventions suitable for this group of people. Methods A site-based sampling method was used to conduct a questionnaire survey on MSW in Shenzhen and blood samples were collected to detect HIV / syphilis infection. Results The survey of 206 MSWs, mean age (24.1 ± 3.98) years, HIV positive rate of 1.5% (3), syphilis positive rate of 2.9% (6). Other provinces registered 85.4% (176 people), while self-orientation was 87.9% (181 cases). 49.5% (102 persons) had unprotected sex with female guests; the most recent rate of condom use was 85.9% (177 persons); and the awareness rate of AIDS knowledge was 57.3% (118 persons). Self-orientation evaluation, unprotected sex with female guests, and recent use of condom with female guests, related to HIV / syphilis infection (P <0.05). In the multivariate analysis, self-orientation was assessed as homosexuality [odds ratio (OR) = 53.604], and unprotected sex with female guests (OR = 13.185) was a risk factor for MSW HIV / syphilis infection. Conclusion MSW in Shenzhen has high liquidity, low infection rate of HIV and syphilis, low AIDS awareness rate and high incidence of unprotected commercial sex. Publicity, education and behavior intervention should be strengthened to increase condom use rate.
