title: History of abortion and perinatal outcomes associated with preeclampsia in nulliparous Japanese women.
abstract: The purpose of the present study was to examine the influence of history of abortion on the next pregnancy outcomes associated with preeclampsia. This investigation involved 5206 nulliparous Japanese women with singleton pregnancies who delivered after 22 weeks of gestation. The patients were divided into two groups: those with a history of spontaneous and/or artificial abortion during the previous pregnancies after the marriage with the same partner (n&#x2009;=&#x2009;1029) and those without a history of abortion (n&#x2009;=&#x2009;4173). There was no significant difference in the incidence of preeclampsia between the 2 groups with and without previous abortions (4.0% vs. 3.9%, p&#x2009;=&#x2009;0.91). In addition, there were no significant differences in the incidence of perinatal complications associated with preeclampsia between the 2 groups. Although further studies may be needed, based on the current results history of abortion does not seem to affect perinatal outcomes associated with preeclampsia.
