广东省2016年男性性病门诊就诊者淋球菌和生殖道沙眼衣原体感染状况及影响因素

Gonorrhoea and genital chlamydia trachomatis andassociated risk factors in male clients to sexually transmitted disease clinics in Guangdong

目的了解广东省男性性病门诊就诊者淋球菌、生殖道沙眼衣原体（GCT）感染及其影响因素,为性病防控提供理论依据。方法 2016年4—6月,结合广东省艾滋病病毒（HIV）哨点监测开展此项研究。选取男性性病门诊就诊者为调查对象,进行问卷调查并收集调查对象血液和尿液标本进行检测。结果调查共收集有效问卷1 718例,平均年龄为（41±13.78）岁,20～49岁占73.7%（1 266例）;已婚占71.5%（1 228例）,广东籍占86.3%（1 482例）,汉族占99.1%（1 701/1 716）。近3个月有异性商业性行为的占31.6%（543/1 717）,26.8%（460/1 715）的人与临时性伴发生过性行为。淋球菌感染率为3.5%（59/1 699）,生殖道沙眼衣原体感染率为8.7%（147/1 699）。多因素Logistic回归结果显示,淋球菌感染的危险因素包括低年龄[比值比（OR）=2.79,95%可信区间（CI）：1.20～6.51]、最近3个月有异性商业性行为（OR=2.83,95%CI：1.59～5.06）、最近1年被诊断为性病（OR=2.11,95%CI：1.13～3.94）和GCT感染（OR=2.56,95%CI：1.31～4.98）。GCT感染的危险因素包括低年龄（OR=3.76,95%CI：1.50～9.43）、不知晓艾滋病相关知识（OR=1.56,95%CI：1.09～2.23）、最近3个月有异性商业性行为（OR=1.55,95%CI：1.08～2.23）和淋球菌感染（OR=2.55,95%CI：1.32～4.93）。结论广东省男性性病门诊就诊者淋球菌和GCT感染危险因素较多,应针对性活跃年龄段且有商业性性行为者采取针对性的干预措施。

Objective To investigate the prevalence of gonorrhoea and genital chlamydia trachomatis and associated risk factors in male clients to sexually transmitted disease clinics in Guangdong and provide integrated prevention and control strategy.Methods Convenient sampling was used to recruit the participants from April to June in 2016 in Guangdong.Information about their socio-demographic characteristics and sexual behaviors were selected by using aquestionnaire,and blood samples were taken to test HIV antibodies,syphilis,and HCV.Urine samples were taken to test gonorrhea and GCT.Results A total of 1718 participants were recruited.The positive rates of gonorrhoea and GCT were 3.5%（59/1699）and 8.7%（147/1699）,respectively.Multivariate analysis showed that risk factors for gonorrhoea included low age group（OR=2.79,95%CI：1.20-6.51）,experiences in commercial sex with females in the last three months（OR=2.83,95%CI：1.59-5.06）,sexually transmitted diseases in the last year（OR=2.11,95%CI：1.13-3.94）and GCT infection（OR=2.56,95%CI：1.31-4.98）.Risk factors for GCT infection included low age group（OR=3.76,95%CI：1.50-9.43）,unawareness of HIV knowledge and HIV prevention（OR=1.56,95%CI：1.09-2.23）,commercial sex with female in the last three months（OR=1.55,95%CI：1.08-2.23）,and gonorrhoea positive（OR=2.55,95%CI：1.32-4.93）.Conclusion This study indicates that the male clients to STD clinics have more risk factors associated with gonorrhoea and GCT infection,and targeted intervention measures should be implemented among the group,especially those at sexual active ages and those having commercial sex.
