Summary:We sought to evaluate the association between prior spontaneous preterm delivery and subsequent pregnancy outcome. A total of 1711 multiparous women with singleton gestations were prospectively evaluated at 23 to 24 weeks' gestation.

If a prior spontaneous preterm delivery had occurred, the gestation of the earliest prior delivery (13-22, 23-27, 28-34, and 35-36 weeks' gestation) was recorded. Current gestations were categorized as spontaneous preterm delivery at
