性病及泌尿外科门诊男性就诊者生殖道沙眼衣原体和淋球菌感染状况及相关因素

Prevalence and related factors of chlamydia trachomatis and neisseria gonorrhoeae infection among men visiting STD and urology clinics in Bao’an district,Shenzhen

目的了解深圳市宝安区性病及泌尿外科门诊男性就诊者生殖道沙眼衣原体(CT)及淋球菌(NG)感染现状及相关因素。方法2018年4-5月,对辖区4所医院性病及泌尿外科门诊符合纳入标准的男性就诊者进行问卷调查及尿液标本生殖道沙眼衣原体及淋球菌核酸检测。结果共调查804人,CT及NG阳性率分别为10.6%(85人)、5.0%(40人);其中性病门诊CT及NG阳性率分别为8.9%(35/393)、1.8%(7/393),泌尿外科门诊CT及NG阳性率分别为12.2%(50/411)、8.0%(33/411)。NG感染是CT感染的相关因素[调整比值比(aOR)=3.54,95%可信区间(CI):1.70~7.37,P=0.001];NG感染的相关因素包括泌尿外科门诊就诊(aOR=2.14,95%CI:1.41~3.25;P<0.001)、无业/待业者(aOR=4.34,95%CI:1.47~12.80,P=0.008)及CT感染(aOR=3.16,95%CI:1.48~6.73,P=0.003)。结论宝安区性病及泌尿外科门诊男性就诊人群CT感染率高,同时泌尿外科门诊NG感染率高;CT及NG感染存在交互作用,无业/待业是NG感染的相关因素。

Objective To understand the prevalence and related factors of chlamydial trachomatis(CT)and neisseria gonorrhoeae(NG)infection among men visiting the clinics of sexually transmitted diseases(STD)and urology.Methods The male patients visiting the clinics of the four hospitals and meeting the criteria of inclusion,were investigated with questionnaires from April to May 2018.CT and NG infection was determined by nucleic acid amplification test(NAAT)on self-collected urine specimens.Results Of the 804 patients recruited,10.6%(85)and 5.0%(40)were tested positive for CT and NG,with the prevalence of 8.9%(35/393)CT and 1.8%(7/393)NG among the male patients to STD clinics and 12.2%(50/411),8.0%(33/411)among those to urology clinics.Those infected with NG[adjusted odds ratio(aOR)=3.54;95%CI:1.70-7.37;P=0.001]were more likely to be positive with CT.Those visiting urology clinics(aOR=2.14;95%CI:1.41-3.25;P<0.001),being unemployed(aOR=4.34;95%CI:1.47-12.80;P=0.008)and infected with CT(aOR=3.16;95%CI:1.48-6.73;P=0.003)were more likely to be positive with NG.Conclusion CT is prevalent among men visiting the clinics of STD and urology,while NG is also prevalent among those visiting urology clinics in Bao’an district,Shenzhen.Being unemployed is the factor related to NG infection and the interaction exists between CT and NG infection.
