Elevated maternal blood glucose in pregnancy may increase heart defect risk
Researchers linked every 10 mg per deciliter increase in maternal blood glucose levels during pregnancy to an 8% higher likelihood of having infants with cardiac malformations, even after adjusting for maternal age, pre-existing maternal diabetes and prepregnancy body mass index. The findings in the Journal of Pediatrics were based on data involving 19,107 mother-child pairs.
