Key clinical point: Prenatal exposure to hypertensive disorders during pregnancy (HDP), particularly preeclampsia and eclampsia, increased the risk for all-cause mortality in offspring from birth to young adulthood, with early-onset and severe preeclampsia exposure notably increasing the risk.
Major finding: Offspring exposed vs not exposed to maternal HDP were at a 26% higher risk for all-cause mortality (adjusted hazard ratio [aHR] 1.26; 95% CI 1.18-1.34), with the risk being 29% (aHR 1.29; 95% CI 1.20-1.38) and 188% (aHR 2.88; 95% CI 1.79-4.63) higher on exposure to preeclampsia and eclampsia, respectively. The all-cause mortality risk was much higher in offspring prenatally exposed to early-onset and severe preeclampsia (aHR 6.06; 95% CI 5.35-6.86).
Study details: This population-based cohort study included 2,437,718 offspring born between 1978 and 2018, of which 102,095 were prenatally exposed to maternal HDP.
