title: Timing of delivery after external cephalic version and the risk for cesarean delivery.
abstract: OBJECTIVE
  To estimate the association between time of delivery after external cephalic version at term and the risk for cesarean delivery.
  
  
  METHODS
  This retrospective cohort study included all successful external cephalic versions performed in a tertiary center between January 1997 and January 2010. Stepwise logistic regression was used to calculate the odds ratio (OR) for cesarean delivery.
  
  
  RESULTS
  We included 483 external cephalic versions in this study, representing 53.1% of all external cephalic version attempts. The incidence of cesarean delivery for 139 women (29%) who gave birth less than 96 hours from external cephalic version was 16.5%; for 344 women (71%) who gave birth greater than 96 hours from external cephalic version, the incidence of cesarean delivery was 7.8% (P = .004). The adjusted OR for cesarean delivery was 2.541 (95% confidence interval 1.36-4.72). When stratified by parity, the risk for cesarean delivery when delivery occurred less than 96 hours after external cephalic version was 2.97 and 2.28 for nulliparous and multiparous women, respectively.
  
  
  CONCLUSIONS
  Delivery at less than 96 hours after successful external cephalic version was associated with an increased risk for cesarean delivery.
