Do hypertensive diseases of pregnancy disrupt neurocognitive development in offspring?
The current study sought to determine whether hypertensive diseases of pregnancy (gestational hypertension and pre-eclampsia) are associated with neurocognitive outcomes in middle childhood. Participants were members of the Western Australian Pregnancy Cohort (Raine) Study. Data were available for 1389 children (675 females; mean age = 10.59 years; SD = 0.19). ⋯ Gestational hypertension (without pre-eclampsia) reduced offspring PPVT-R scores by 1.71 points [95% CI -3.39, -0.03] and pre-eclampsia led to a reduction of 3.53 points [95% CI -8.41, 1.35], although this latter association did not achieve statistical significance. There was no effect of the two- (P = 0.99) or three-level (P = 0.92) predictor variable on RCPM scores. Maternal hypertensive diseases of pregnancy are a risk factor for a small reduction in offspring verbal ability.
