Pregnancy outcome after previous induced abortion.

The outcome of pregnancy was studied in 325 patients with an induced abortion in their previous pregnancy, together with 721 control patients. The patients were matched for age, parity and social class. Smoking and unplanned pregnancies were found to be more comon among abortion patients than among the control patients. As regards pregnancy complications, bleeding during pregnancy and placental retention were found to be significantly more common in the index group. No statistical differences were noticed in gestation length, birthweight, rate of spontaneous abortion and perinatal mortality in the pregnancy following induced abortion as compared with control patients.
