title: Labor progression in teenage women.
abstract: OBJECTIVE
  Compare labor progression in first and second stages in women < 18 years with those ≥18 years.
  
  
  METHODS
  Retrospective cohort study of consecutive women at term that reached the second stage of labor between 2004 and 2008. The first stage in women < 18 years was compared with women ≥18 years. Average labor curves were constructed and median time spent to progress 1 cm in dilation and total time from 4 to 10 cm was estimated. Time spent pushing and total duration of second stage were compared between groups. Analyses were then stratified by parity.
  
  
  RESULTS
  There was no significant difference in progress of the first stage of labor between women < 18 years and those ≥18 years. In the second stage, nulliparous teenage women were less likely to have a duration > 60 or 120 minutes.
  
  
  CONCLUSIONS
  Laboring women < 18 years should be managed with the same expectations of labor as women ≥18 years.
