Prevalence of HIV infection and sexually transmitted diseases and associated risk factors among female sex workers in Guangdong province
摘要: 目的了解广东省某市暗娼艾滋病病毒（HIV）和性病感染率，探索性病感染的相关危险因素。方法在广东省某市采用同伴推动抽样法（RDS）招募社区内暗娼，采用统一的面对面访谈问卷表的方式进行定量调查。采集血液进行HIV和梅毒抗体的检测，采集宫颈分泌物进行淋病和衣原体检测。结果本次研究共招募到320名暗娼，其HIV感染率为0，梅毒、淋病和衣原体感染率分别为8.0%，9.5%和3.9%，性病感染率（感染上述任一疾病的比例）为19.7%。多因素logistic回归分析结果显示，受教育年限和对HIV感染危险的意识是性病感染的独立性保护因素，而知晓艾滋病、固定性伴决定安全套的使用、低端场所类型和商业性性行为高收费是性病感染的危险因素。结论广东省暗娼HIV流行尚处于低水平，但性病感染率较高，今后针对暗娼的干预项目要重点覆盖低端场所的目标人群，同时要注重对暗娼的固定性伴的行为干预。Abstract: ObjectiveTo analyze the prevalence of HIV infection and sexually transmitted diseases (STDs) and explore the risk factors associated with STDs among female sex workers (FSWs) in a prefecture in Guangdong Province, provide evidence to develop intervention strategies. MethodsRespondent-driven sampling (RDS) was used to recruit FSWs in the community. Face-to-face interviews were conducted to collect information on risk behaviors by using structured questionnaires. Blood samples were taken to test HIV and syphilis antibody and cervical swabs were taken for the detection of gonorrhea and Chlamydia. ResultsA total of 320 FSWs were recruited from the community. Laboratory testing revealed that the prevalence of HIV infection was 0%, the prevalence of syphilis, gonorrhea and Chlamydia was 8.0%, 9.5% and 3.9% respectively; the prevalence of other STD was 19.7%. The multivariate logistic regression model indicated that ones years of education and perception of risk for HIV infection were protective factors from STDs. Awareness of AIDS only, condom use by regular sex partners will, lower level facility and higher charge for commercial sex were risk factors associated with STDs. ConclusionHIV prevalence among FSWs in Guangdong was low and the prevalence of STDs is relatively high. The intervention programs should cover low- class FSWs and the interventions to regular sex partners of FSWs should be conducted too.
