title: [Chlamydia trachomatis infection and risk factors in pregnant women].
abstract: BACKGROUND
  In order to assess the frequency of Chlamydia trachomatis infection in pregnancy in São Paulo (Brazil), a group of 122 successive pregnant women (80 adults and 42 adolescents) attending the pre-natal care clinic of the Department of Obstetrics were studied.
  
  
  METHODS
  The exam consisted of an epidemiological survey, a complete obstetrical clinical examination and the assessment of the presence of C. trachomatis in the vagina by ELISA (Chlamydiazyme).
  
  
  RESULTS
  A total of 11 women (9%) were positive, being 8 (10%) of them adults and 3 (7%) adolescents.
  
  
  CONCLUSIONS
  In São Paulo the age of the patient as well as the marital status, the number of sexual partners, the existence of other sexually transmitted diseases, the presence of cervicitis or the occurrence of abortions could not be considered as risk factors for the presence of the Chlamydia trachomatis.
