title: Prevalence of Chlamydia trachomatis in women attending sexually transmitted disease clinics in the Colombo district, Sri Lanka.
abstract: BACKGROUND
  In Sri Lanka little is known about the prevalence of Chlamydia trachomatis (CT) infection. Objective was to determine the prevalence of CT in female patients attending sexually transmitted disease (STD) clinics in the Colombo district.
  
  
  METHODS
  A descriptive cross-sectional study was carried out for the prevalence of CT in all female patients (n = 168) more than 18 years of age, attending two STD clinics in the Colombo district from January to May 2012. Endocervical swabs were collected and tested for CT using the Amplicor CT/NG polymerase chain reaction assay.
  
  
  RESULTS
  Prevalence of CT in females attending the STD clinics in the Colombo district was 8.3%. Mean age of those infected with CT was 32.9 years (SD ± 8.2). Majority of females with CT infections were Sinhalese and married. There was no significant association with age, ethnicity or being married or not. Females who did not attend school, or had their education only up to Grade 5 were significantly found to have six times the risk of having CT infection (95% CI = 1.8-22.6). A significant association was found with number of sexual partners but not with commercial sex work or past history of STD.
  
  
  CONCLUSIONS
  Prevalence of CT was moderately high in this population.
