J. Zhang et al., PREGNANCY-INDUCED HYPERTENSION AND EARLY NEONATAL DEATH - A CASE-CONTROL STUDY, American journal of perinatology, 10(5), 1993, pp. 401-403
Literature on the association between pregnancy-induced hypertension a
nd early neonatal death is limited. The present case-control study con
sisted of 342 early neonatal deaths and 523 frequency-matched controls
. After controlling for other factors such as infant sex, gravidity, m
aternal age, threatened abortion, and maternal anemia, moderate to sev
ere pregnancy-induced hypertension was associated with an increased ri
sk of early neonatal death with apparent dose-effect gradients (odds r
atio = 1.8 for moderate and 2.2 for severe). The biologic plausibility
of pregnancy-induced hypertension as a cause of neonatal mortality is
discussed.
