250例农村地区女性性工作者生殖道沙眼衣原体感染现状和相关因素分析

 目的 分析农村地区女性性工作者生殖道沙眼衣原体的感染情况，并探讨相关的危险因素。方法 在广东省云浮市农村地区采用方便抽样法招募250例女性性工作者。采用问卷调查收集一般人口学特征和性行为学特征。采集静脉血进行梅毒和HIV的检测，采集尿液利用荧光聚合酶链式反应检测淋球菌和沙眼衣原体。结果 生殖道沙眼衣原体的感染率为22.00%（55/250），淋球菌感染率为11.60%（29/250），梅毒感染率为0.80%（2/250），无HIV感染。55例衣原体感染人群中，淋球菌感染率为40.00％，无梅毒感染者。月收入越低（OR=3.052）、教育程度越低（OR=2.611）、最近一个月不持续使用安全套(OR=3.226)和平均每周性伴数量越多(OR=2.109)者生殖道沙眼衣原体感染越高。结论 农村地区的女性性工作者生殖道沙眼衣原体感染率较高，建议加强对农村地区女性性工作者生殖道沙眼衣原体的检测和健康宣教，提高自我防控风险意识。

Analysis of status and related factors of genital tract Chlamydia trachomatis infection among 250 female sex workers in rural areas

Objective To analyze the infection rate of genital tract Chlamydia trachomatis infection in female sex workers in rural areas, and explore related risk factors. Methods Convenient sampling was used to enroll 250 subjects in rural areas of Yunfu city, Guangdong province. A questionnaire survey was used to collect demographic characteristics and sexual behavior characteristics. Blood sample from subjects was used for syphilis and HIV testing, while urine sample was collected for detection of gonorrhea and chlamydia, using real time PCR. Results The infection rate of Chlamydia trachomatis in the genital tract was 22.00% (55/250), while the infection rate of Neisseria gonorrhoeae was 11.60% (29/250). The infection rates of syphilis and HIV were 0.80% (2/250) and 0, respectively. In subjects with chlamydia infection, the co-infection rates of gonococcus and syphilis were 40.0% and 0, respectively. The higher infection rate of Chlamydia trachomatis in the genital tract was associated with lower monthly income (OR=3.052), lower education level (OR=2.611), the non-continuous use of condoms in the last month (OR=3.226), more encounter partners per week (OR=2.109). Conclusions Female sex workers in rural areas have a high rate of Chlamydia trachomatis infection in genital tract. It is recommended to strengthen the detection and health education of genital tract Chlamydia trachomatis infection, and improve the self-prevention and risk control awareness of genital tract infection with Chlamydia trachomatis.
