The newborns of obese women had
more than double the risk of
macrosomia compared to those of
women with normal weight.
Data from the Diabetes in Early Pregnancy Study indicate
that fetal birth weight correlates best with secondand
third-trimester postprandial blood sugar levels and
not with fasting or mean glucose levels [3] . When postprandial
glucose values average 120 mg/dl or less, approximately
20% of infants can be expected to be macrosomic,
and if the glucose values are as high as 160 mg/dl, the rate
of macrosomia can reach up to 35%.
