What are the incidence and risk factors of preeclampsia?
Preeclampsia occurs in approximately 5–10% of pregnan-cies and eclampsia manifests in 0.2–0.7% of pregnancies. The young primigravida with poor prenatal care is at highest risk for preeclampsia. Preeclampsia is associated with rapid uterine enlargement such as occurs with hydatidiform mole, diabetes mellitus, and multiple gestations. There is a 33% probability of preeclampsia recurring with subsequent pregnancies.
