北京市石景山区女性性工作者阴道外用杀微生物剂可接受性初步研究

Acceptability of vaginal microbicides among female sex workers in urban Beijing, China

目的探索女性性工作者对阴道外用杀微生物剂的使用意愿及其相关因素。方法采用横断面设计，在北京市石景山区按方便抽样，选取54名女性性工作者进行问卷调查。主要评价指标包括杀微生物剂可接受性得分、危险性行为、安全套使用率、性病史、艾滋病／性病认知风险等。结果被调查的女性性工作者对杀微生物剂的可接受性平均得分为2.73（范围1-4）：可接受性的差异因不同性伴模式（P=0.049）、是否做过HIV检测（P=0.037）、是否担心感染性病（P=0.042）有统计学意义；使用及隐蔽使用杀微生物剂的意愿随不同类型性伴有统计学意义（P=0.001）。结论接受调查的女性性工作者对杀微生物剂的态度普遍较积极，但影响使用的因素尚待进一步研究。

Objective To explore the attitudes and willingness towards vaginal microbicides use among female sex workers （FSWs） for HIV/AIDS and sexually transmitted infection （STI） prevention in an urban district of Beijing, China, as well as its related factors. Methods A cross-sectional study using convenience sampling was conducted. A total of 54 FSWs were recruited from Shijingshan District in urban Beijing. Main outcome variables were measured by microbicide acceptability score with questionnaire, including high-risk sexual behaviors, self-reported condom use, self-reported HIV/STI history and perception on the risk of HIV/STI. Results Mean score of microbicide acceptability in FSWs was 2.73 （ranging 1 to 4）. Acceptability score varied by the type of their sex partner （P=0.049） , experience of HIV testing （P= 0.037） and concerns about contracting STI （P= 0.042）. Willingness to use and covert use of microbicides in FSWs varied significantly with their sex partners （P=0.001）. Conclusion FSWs in Shijingshan district might have a positive response to vaginal microbicides use across all hypothetical characteristics in general. Further study is needed for comprehensive understanding of contextual factors related to it.
