Pregnancy following induced abortion: maternal morbidity, congenital abnormalities and neonatal death

Abstract

Summary. In a prospective cohort study of the long‐term sequelae of induced abortion, a comparison is made between a group of 6418 women who had an induced abortion (cases) and a control group of 8059 women recruited with an unplanned pregnancy which was not terminated with an induced abortion (controls). The present paper reports on 729 cases and 1754 controls who had a post‐recruitment pregnancy. In general, prior induced abortion had no material effect on the rate of pregnancy‐related morbidity, nor on the rate of congenital abnormalities and neonatal death in the offspring. There was, however, a significant difference in two specific conditions. In the post‐index pregnancy in the cases there was an increased relative risk (RR 2·26) of the occurrence of urinary tract infection and a decreased risk (RR 0·25) of pregnancy‐related anaemia.
