Maternal Glucose Level Linked to Childhood Obesity Risk
As maternal blood glucose level during pregnancy increases, so does the child’s risk for obesity at age 5 to 7 years, reports a study in Diabetes Care.
U.S. researchers examined the medical records of nearly 9500 mother-child pairs. During pregnancy, the women were screened for gestational diabetes. In addition, obesity in the offspring was determined when the child was 5 to 7 years old.
Overall, the risk for childhood obesity increased significantly as maternal blood glucose level increased; the association was particularly striking for fasting blood glucose. However, after multivariate adjustment, the obesity risk was not increased among children whose mothers had met criteria for gestational diabetes and were likely treated.
The authors say their findings “suggest that [gestational diabetes mellitus] treatment may decrease the risk of childhood obesity and provide an additional reason for screening for GDM in pregnancy.”
