title: [Obstetric data in a population with postural changes during labor and delivery].
abstract: BACKGROUND
  The aim of this study was to describe the potential impact of an active birth on classical obstetrical outcomes, as labor duration, cesarean section rate, couples and team satisfactions.
  
  
  METHODS
  This observational study was prospective, monocentric and took place between May 2007 and February 2009 at the maternity ward of the University Hospital of Caen, France. An "active birth" was defined as an active latent-phase (having a change in position and/or a bath and/or a walk) followed by at least three changes in position during the active phase. The suggested positions were: lateral or dorsal decubitus, ROSA, on all fours, seated, standing and crouch. A position must have lasted at least 20 minutes to be considered.
  
  
  RESULTS
  Out of the 1906 women included, 828 had an active birth (43.4%). Due to our definition of an "active birth", a "non-active birth" was significantly associated with a quicker labor. An "active birth" was associated with a decreased rate of cesarean section (OR=0.71; IC95%=[0.51-0.99]). The parturients satisfaction median was 9 on a scale of 0 to 10, the spouses'one was 10. Midwives were more satisfied when it was an "active birth".
  
  
  CONCLUSIONS
  Significant associations with active births were highlighted, which would require to be validated by a randomised study. This practise plenty satisfied couples and midwives. In fact, no litterature exists to date. A consensus about the definition of an active birth is still necessary in order to lead to guidelines.
