title: [Pregnancy and delivery of teenagers: Is the obstetrical prognosis worst between 13-15years old?]
abstract: OBJECTIVE
  To assess the prognosis of pregnancy and delivery of 13-15years old patients compared to teenagers aged of 16-17.
  
  
  METHODS
  Single-center retrospective study of a continuous series of 13-15 teenagers followed in a public maternity between 1996 and 2012 compared to a series of patients aged of 16-17 matched on the day of the delivery (two controls for a case).
  
  
  RESULTS
  Seventy-three teens 13-15 were followed during the study period, and 146 adolescents aged 16-17 were included and matched. The two groups did not differ regarding size, weight or medical history. Younger patients were more often educated than older ones (46.6 vs 27.4%, P<0.01). The incidence of congenital malformations was high but substantially identical in the two groups (9.6 vs 11.0%, NS), as well as prematurity concerned that almost one third of patients (27.4 vs 30.1%, NS). The Caesarean section rate was low (11.0 vs 10.3%, NS). The frequency of birth weight below the 10th percentile did not differ between groups (15.1 vs 19.9%, NS).
  
  
  CONCLUSIONS
  Teenage girls of 13-15years old have high perinatal risk (prematurity, congenital malformation), and frequently delivery vaginally. These risks do not seem superior to those of adolescent girls aged of 16-17years old.
