title: [Delivery in nulliparous women aged < or = 18 years].
abstract: METHODS
  A retrospective study of 733 nulliparous women who gave birth at the Department of Obstetrics and Gynecology at the University of Bari, in the period from 1-1-1994 to 31-12-1995, was performed to evaluate the outcome of pregnancy and neonatal outcome in adolescents < or = 18 years old. The sample was subdivided into two subgroups; the first of 114 girls < or = 18 years old; the latter of 619 women 22-34 years of age, and they were compared.
  
  
  RESULTS
  We have found a more lengthy term of pregnancy (39.66 weeks vs 39.27 weeks p = 0.008) and a greater incidence of vacuum extraction (VE) in the group of < or = 18 years old (7.89% vs 3.23% p = 0.03).
