Higher in utero vitamin D levels may prevent high BP in children: JAMA
USA: Higher cord vitamin D blood levels in pregnant women with preeclampsia may lower the risk of high blood pressure (BP) in their children during childhood and adolescence, finds a recent study. Results of the study, published in the journal JAMA Network Open suggests that optimizing the maternal prenatal vitamin D levels may prevent high BP and future cardiovascular disease (CVD) in children born to women with preeclampsia.
Maternal preeclampsia could be a risk factor for high BP in children. However, there is no information on whether the intergenerational association between maternal preeclampsia and BP in their children differs by cord blood vitamin D levels. Mingyu Zhang, Johns Hopkins Bloomberg School of Public Health, Baltimore, Maryland, and colleagues, therefore, assessed the associations between maternal preeclampsia and offspring systolic BP across childhood and adolescence. They also tested whether these associations vary by cord blood 25-hydroxyvitamin D [25(OH)D] concentrations -- a biomarker of in utero vitamin D status.
