BACKGROUND AND OBJECTIVES: Preeclampsia is a serious multisystem blood pressure disorder during pregnancy that is associated with increased long-term risk of cardiovascular disease to the mother and offspring. We investigated the vascular health of children exposed to intrauterine preeclampsia.
MATERIALS AND METHODS: This was a cross-sectional study of offspring in a prospective cohort of women with complications during pregnancy. Children aged between 2 and 5 years [median age 4.7 (2.8, 5.1) years] exposed to intrauterine preeclampsia (n = 26) or normotensive controls (n = 34), were recruited between July 2020 and April 2021. Vascular health was assessed by measuring aortic intima-media thickness and pulse wave velocity. Univariate generalized linear regression models were used to explore associations between vascular measurements and explanatory variables.
RESULTS: Children exposed to preeclampsia had a lower body mass index at assessment (15.5 vs. 16.2 kg/m2, p = 0.04), birth weight (2.90 vs. 3.34 kg, p = 0.004), gestational age at birth (37.5 vs. 39.4 weeks, p < 0.001) and higher frequency of preterm birth (27% vs. 6%, p = 0.02). There were no differences in vascular health between children exposed to preeclampsia vs. controls (mean aortic intima-media thickness 0.575 mm vs. 0.563 mm, p = 0.51, pulse wave velocity 4.09 vs. 4.18 m/s, p = 0.54) and there were no significant associations in univariate analyses.
CONCLUSIONS: There were no major adverse differences in vascular health which contrasts with existing studies. This suggests exposure to intrauterine preeclampsia may result in a less severe cardiovascular phenotype in young children. While reassuring, longitudinal studies are required to determine if and when exposure to intrauterine preeclampsia affects vascular health in children.
