Objective: To estimate the prevalence of and risk factors for Chlamydia trachomatis (CT) infection in young parturient women in Brazil. Methods: A national cross-sectional study of parturient women, aged 15 to 24 years, attending Brazilian public hospitals was performed in 2009. Participants answered a questionnaire including demographic, behavioral, and clinical data. A sample of urine was collected and screened for CT and Neisseria gonorrhoeae (NG), using polymerase chain reaction, Amplicor CT/NG (Roche Molecular Systems, Branchburg, NJ, USA). Results: A total of 2400 women were selected and 2071 (86.3%) participated in the study. Mean age was 20.2 years (standard deviation = 2.7). Prevalence rates of CT and NG were 9.8% (95% CI: 8.511.1) and 1.0% (95% CI: 0.6%1.4%), respectively. Four percent of women infected with CT also had NG infection. CT associated factors were: being younger (1519 years old) OR= 1.6 (95% CI: 1.152.17); first sexual intercourse before 15 years of age OR= 1.4 (95% CI: 1.046.24); having more than 1 sexual partner in lifetime OR= 1.6 (95% CI: 1.132.26); Pap smear screening more than 1 year OR= 1.5 (95% CI: 1.082.05); and NG infection OR= 7.6 (95% CI: 3.0519.08). Conclusions: This study shows a high prevalence of CT infection among young pregnant women in Brazil. We suggest that CT screening should be included as part of antenatal care routine in this group in Brazil
