Implication

Prospective cohort study reveals no link between maternal hypertension during pregnancy and lower IQ in offspring, indicating no adverse long-term cognitive effects.

Key Points

To examine whether hypertensive disorders during pregnancy are associated with offspring intelligence quotient (IQ) at ages 8 and 16 years.
Analyzed data from the UK-based Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort, evaluating mother–child pairs at age 8 (N>4,900) and age 16 (N>3,300).
Assessed offspring IQ using a shortened Wechsler Intelligence Scale for Children (WISC-III) at age 8 and the Wechsler Abbreviated Scale of Intelligence (WASI) at age 16 via binary and multinomial logistic regression models.
Hypertensive disorders of pregnancy were not associated with lower offspring IQ at either age 8 or age 16.
Gestational hypertension, but not pre-eclampsia, was associated with higher odds of above-average IQ compared to average IQ at age 16 in multinomial models, but this finding did not appear at age 8 and was not replicated across IQ tertiles.
