Pregnancy sugar levels affect babies

CHICAGO – The higher a pregnant woman’s level of blood sugar, the greater the risk to her newborn – whether the mother has diabetes or not, the largest study on the problem suggests.

The findings released Friday may lead to more women being diagnosed with diabetes during pregnancy and given stricter diet advice or medication to lower blood sugar.

The research involved more than 23,000 pregnant women in nine countries. It found a surprisingly strong relationship between the blood sugar levels of the women and the rate of big babies and first-time Caesarean sections, said lead investigator Dr. Boyd Metzger of Northwestern University.

The newborns also were more likely to have low blood sugar levels and high insulin levels if their mothers’ blood sugar levels were higher. The problems can lead to obesity, diabetes and high blood pressure later in life.

Large babies risk shoulder damage and other injuries if delivered vaginally and lead to more C-sections, which also pose health risks to mothers and babies.

Researchers reported the findings Friday at the American Diabetes Association’s annual scientific meeting.
