The Impact of Multiple Induced Abortions on the Outcome of Subsequent Pregnancy

Abstract

The obstetric outcome of 285 women with a history of previous multiple induced abortions is compared to that of 285 age matched primigravidas. In the study group, 219 women had 2 previous induced abortions and 66 had 3 or more, the maximum number being 8. There was a higher incidence of unmarried women and smokers in this group but a lower incidence of uneducated women. There was no difference in the incidence of antenatal complications between the 2 groups. The mean gestation at delivery, duration of labour and mode of delivery were comparable. There was an increased incidence (p less than 0.01) of retained placenta in the subgroup of women with 3 or more previous induced abortions. There were no maternal or perinatal deaths. The mean birth-weight was comparable and there were no infants weighing less than 1,500 g in either group. We conclude that multiple previous induced abortions appear to have minimal impact on the obstetric outcome of subsequent pregnancy in this population, and in the absence of other risk factors there is no need to alter standard obstetric management in this group of women.
