Influence of pregnancy outcome on subsequent pregnancy

Int J Gynaecol Obstet. 1982 Apr;20(2):145-7. doi: 10.1016/0020-7292(82)90028-5.

Abstract

In this study to determine the harmful effect of abnormal pregnancy outcome on the immediately following pregnancy, 573 recently delivered women (with 2347 pregnancies) were interviewed. Data were recorded on their pregnancy outcomes (normal, abortion, stillbirth and congenital malformation), as well as on their interpregnancy intervals. A significant difference was found between the chances of having a spontaneous abortion following a normal outcome (5.5%) against that following a spontaneous abortion (31.1%). Also, the chances of a normal outcome following a normal outcome were 92.4%, compared with 63.9% following a spontaneous abortion. The delivery of a malformed baby is associated with a larger proportion of abortion and congenital malformation in the subsequent pregnancy, while stillbirth was followed by a larger proportion of abortion and stillbirth. A longer interpregnancy interval did not appear to have any protective effect on the subsequent pregnancy.

PIP: In this study to determine the harmful effect of abnormal pregnancy outcome on the immediately following pregnancy, 573 recently delivered Kuwati women (with 2347 pregnancies) were interviewed. Data were recorded on their pregnancy outcomes (normal, abortion, stillbirth and congenital malformation), as well as on their interpregnancy intervals. A significant difference was found between the chances of having a spontaneous abortion following a normal outcome (5.5%) against that following a spontaneous abortion (31.1%). Also, the chances of a normal outcome following a normal outcome were 92.4%, compared with 63.9% following a spontaneous abortion. The delivery of a malformed baby is associated with a larger proportion of abortion and congenital malformation in the subsequent pregnancy, while stillbirth was followed by a larger proportion of abortion and stillbirth. The etiologic mechanisms are still largely speculative, including the trophoblastic rest and other hypotheses, although some authorities have already adopted the precautionary measure of advising their patients following a spontaneous abortion to delay the next pregnancy. A longer interpregnancy interval did not appear to have any protective effect on the subsequent pregnancy.
