title: Fetal growth retardation in infants of multiparous and nulliparous women with preeclampsia.
abstract: OBJECTIVE
  Infants of women with preeclampsia are considered at high risk of fetal growth retardation. The purpose of our study was to determine whether the risk differed by parity.
  
  
  METHODS
  We compared the outcomes of 133 case patients with preeclampsia (101 nulliparous women and 32 multiparous women) and 132 normotensive control patients (52 nulliparous women and 80 multiparous women) who delivered at Northern California Kaiser Permanente hospitals between 1984 and 1985.
  
  
  RESULTS
  Women with preeclampsia were more likely than control patients to deliver a small-for-gestational-age infant (adjusted odds ratio 7.0, 95% confidence interval 2.8 to 18.1). After we controlled for smoking status, age, Quetelet index, and race, multiparous women with preeclampsia were at greater risk of having a small-for-gestational-age infant (adjusted odds ratio 29.4, 95% confidence interval 5.2 to 167.5) than were nulliparous women (adjusted odds ratio 4.1, 95% confidence interval 1.2 to 14.1) when compared with normotensive control patients of similar parity. Although multiparous women with preeclampsia had higher mean arterial pressures and somewhat earlier onsets of elevated mean arterial pressure than nulliparous women with preeclampsia, neither of these variables predicted whether the infants would be small for gestational age.
  
  
  CONCLUSIONS
  Multiparous women with preeclampsia are at higher risk of having an infant with fetal growth retardation than are nulliparous women with preeclampsia.
