PP179. The influence of prior abortion on rates of gestational hypertension/pre-eclampsia and spontaneous preterm delivery in nulliparous women

Abstract Introduction Gestational hypertension/preeclampsia (GH) is clearly a heterogeneous condition of which the pathogenesis could be different in women with various risk factors. Nulliparity is a known risk factor for GH, however a previous abortion (spontaneous or induced) may be associated wit...

Description
Summary:Abstract Introduction Gestational hypertension/preeclampsia (GH) is clearly a heterogeneous condition of which the pathogenesis could be different in women with various risk factors. Nulliparity is a known risk factor for GH, however a previous abortion (spontaneous or induced) may be associated with a lower risk of GH. Objectives To examine the effect of abortion history on rates of GH and spontaneous preterm delivery (SPTD) and in nulliparous women. Methods Nulliparous women with an initial prenatal screening at 2 AB’s significant differences were observed in rates of SPTD vs. controls (8.2% vs. 6.0%, p < 0.001), but rates of GH were similar (9.2% vs. 10.2%, p = 0.188). 0 AB (n = 52, 683) 1 AB (n = 17,227) 2 AB’s ( n = 3746) >2 AB’s (n = 1530) Gestational HTN/PE 10.2% 7.8%1 8.3%1 9.2% SPTD 2 prior AB’s.
