title: Pregnant adolescents at risk: sexual behaviors and sexually transmitted disease prevalence.
abstract: OBJECTIVE
  The purpose of this study was to determine the level of high-risk sexual behaviors and the prevalence of chlamydia and gonorrhea among pregnant adolescents.
  
  
  METHODS
  These analyses used data from 203 pregnant and 209 nonpregnant adolescents who were recruited from public health clinics. Data sources included interviewer-administered questionnaires, ligase chain reaction tests for chlamydia/gonorrhea in the third trimester of pregnancy, and state health department reports of chlamydia/gonorrhea. Statistical analyses included logistic regression.
  
  
  RESULTS
  Pregnant adolescents were significantly more likely to have not used condoms during sexual intercourse in the past 30 days compared with nonpregnant adolescents, although other sexual risk behaviors were reduced. Nineteen percent of pregnant adolescents had chlamydia or gonorrhea diagnosed during the pregnancy.
  
  
  CONCLUSIONS
  Pregnant adolescents have high levels of sexually transmitted diseases during pregnancy, and many adolescents use condoms inconsistently. Prenatal care providers may be in a unique position to decrease sexually transmitted diseases among pregnant adolescents by encouraging the reduction of risk behaviors and aggressively screening for sexually transmitted diseases as part of routine prenatal care.
