To estimate the prevalence of sexually transmitted infections (STIs) among female sex workers (FSWs) in the Jiangsu Province, China and measure the association of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections with their potential correlates.
A cross-sectional study on a representative sample of FSWs in Yangzhou and Changzhou cities of Jiangsu was conducted.
185 sex-work venues in Yangzhou and 174 in Changzhou were selected by stratified random sampling. 2972 FSWs (1108 in Yangzhou and 1864 in Changzhou), aged 15 years or more, who agreed to participate and provided blood sample for HIV and syphilis testing were interviewed in these venues. Cervical specimens from 849 randomly chosen participants were then tested for CT and NG.
Proportions of young, school-educated, currently married FSWs who were living alone, migrated from other provinces and engaged in unprotected vaginal intercourse in past 3 months (UVI) were relatively high. Prevalence of HIV, syphilis, CT and NG were 0.20%, 4.88%, 14.61% and 5.42% respectively. Younger age, living alone or with persons other than partners/family members, engaging in UVI and having other STIs seemed to be associated with higher risk of CT or NG infection. Being divorced/widowed and working in middle/low-level venues were identified as additional risk factors for NG.
Based on a representative sample, this initial effort to identify the correlates of CT/NG infections among FSWs of Jiangsu revealed that focused interventions targeting high-risk FSWs are urgently required for controlling STI epidemics in Yangzhou and Changzhou where substantial number of STI cases were identified.
估计中国江苏省女性性工作者（FSW）中性传播感染（STI）的流行率，并衡量沙眼衣原体（CT）和淋病奈瑟菌（NG）感染与潜在相关因素的关联。
对江苏省扬州市和常州市的FSW 进行了一项代表性样本的横断面研究。
通过分层随机抽样选择了 185 个扬州性工作场所和 174 个常州性工作场所。对同意参与并提供艾滋病毒和梅毒检测血样的 2972 名 FSW（扬州 1108 名，常州 1864 名）进行了访谈。然后从 849 名随机选择的参与者中抽取宫颈标本，用于检测 CT 和 NG。
年轻、受过教育、目前已婚、独居、来自其他省份且在过去 3 个月内进行无保护阴道性交（UVI）的 FSW 比例相对较高。HIV、梅毒、CT 和 NG 的流行率分别为 0.20%、4.88%、14.61%和 5.42%。年龄较小、独居或与伴侣/家庭成员以外的人同居、进行 UVI 以及患有其他 STI 似乎与 CT 或 NG 感染的风险增加有关。离婚/丧偶和在中/低级别场所工作被确定为 NG 的额外危险因素。
基于代表性样本，本研究首次尝试确定江苏省 FSW 中 CT/NG 感染的相关因素，结果表明，在扬州和常州发现大量 STI 病例的情况下，迫切需要针对高风险 FSW 进行有针对性的干预，以控制 STI 流行。
