Objective To investigate the prevalence of genital Chlamydia trachomatis (GCT) infection and associated risk factors in male clients attending sexually transmitted disease (STD) clinics in Guangdong and provide integrated intervention strategy for this group.Methods Convenient sampling was used to recruit participants from April to June in 2015 in Guangdong province.The information about their socio-demographic characteristics and sexual behaviors were collected by using a questionnaire,and blood samples were taken from them to test the antibodies against HIV,syphilis and HCV.First pass urine was taken to test GCT and gonorrhea.Results A total of 1 749 participants with the average age of 39.53 years were recruited.The majority of them were married (73.87％,1 292/1 749),residents of Guangdong (92.28％,1 614/1 749) and in Han ethnic group (99.49％,1 740/1 749).The positive rates for GCT,HIV,syphilis,HCV,Neisseria gonorrhea,and WBC in urinalysis were 6.06％ (106/1 749),0.46％ (8/1 749),3.43％ (60/1 749),0.45％ (7/1 550),2.74％ (48/1 749),7.89％ (138/1 749) respectively.Multivariate analysis showed that risk factors for GCT infection include IDUs (OR=13.98,95％CI:3.35-58.38),anal sex with men (OR=3.11,95％ CI:1.45-6.71),Neisseria gonorrhea positive (OR =9.64,95％ CI:5.09-18.24),and WBC positive (OR =1.96,95％ CI:1.08-3.55).Conclusions This study demonstrated the high prevalence of GCT infection in male clients attending STD clinics in Guangdong.Therefore precision intervention should target this population at high-risk.
