title: Pregnancy-induced hypertension and early neonatal death: a case-control study.
abstract: Literature on the association between pregnancy-induced hypertension and early neonatal death is limited. The present case-control study consisted of 342 early neonatal deaths and 523 frequency-matched controls. After controlling for other factors such as infant sex, gravidity, maternal age, threatened abortion, and maternal anemia, moderate to severe pregnancy-induced hypertension was associated with an increased risk of early neonatal death with apparent dose-effect gradients (odds ratio = 1.8 for moderate and 2.2 for severe). The biologic plausibility of pregnancy-induced hypertension as a cause of neonatal mortality is discussed.
