Abstract
BackgroundThe main objective of this study is to examine the epidemiology of Chlamydia trachomatis (CT) infection amongst patients (473 men, 180 women) seen two hospitals in Taiwan.MethodsBetween July 2004 and June 2005, a total of 653 patients provided first-void urine samples for examination of CT using PCR assay.ResultsThe overall prevalence of CT infection was 18.4% (95% confidence interval [CI] 17.3–19.5). Prevalence for men and women were 16.7 % (95% CI 15.3–18.0%) and 22.8% (95% CI 17.5–28.1%), respectively. Age group-specific prevalence was 25.7% (95% CI 22.5–28.9%) in < 20 year olds, 23.5% (95% CI 20.3–26.7%) in 20–24 year olds, 22.3% (95% CI 18.9–25.7%) in 25–30 year olds, and 11.5% (95% CI 10.3–12.7%) in > 30 year olds. Independent risk factors for chlamydial infection included younger age (aged ≤ 30 years) (adjusted odds ratio [AOR] = 2.44; 95% CI 1.52–3.84; p < 0.001), inconsistent condom use (AOR = 2.01; 95% CI 1.32–3.06; p < 0.001), being symptomatic (dysuria, urethral discharge) at the time of testing (AOR = 1.84; 95% CI 1.21–2.80; p < 0.001), and having N. gonorrhoeae infection (AOR = 3.82; 95% CI 2.20–6.58; p < 0.001).ConclusionGenital chlamydial infection is an important sexually transmitted disease in Taiwan. Young Taiwanese persons attending a STD clinic should be screened for CT infection and counselled on condom use.

Summary
The main objective of this study is to examine the epidemiology of Chlamydia trachomatis (CT) infection amongst patients (473 men, 180 women) seen two hospitals in Taiwan. Sexually active people are at high risk for genital infection by Chlamydia trachomatis (CT) [1,2]. It is estimated that 340 million new cases of common bacterial and protozoal sexually transmitted infections occur annually worldwide [3]. An increase in sexually risky behaviour amongst young people and an associated subsequent increase in the prevalence of CT have been reported [4,5]. Serious sequelae among men with untreated infection include urethritis, prostatitis, epididymitis and Reiter syndrome [6]. Active CT infection is an (page number not for citation purposes)
