Pregnancy in women over forty.
In a retrospective review of 440 pregnancies occurring in women over the age of 40, increased frequencies of both perinatal and maternal complications were noted. The perinatal mortality rate of the study group was three times greater than that of the general obstetric population. There were increased incidences of both low and high birthweight infants. Neonatal morbidity was increased. Congenital abnormalities were noted in 12 infants, including 2 infants with cytogenetic abnormalities. Hypertensive disorders complicated one-third of the pregnancies. Diabetes mellitus and abruptio placentae occurred with increased frequency. Cesarean section was required in 12.2% of the deliveries.
