Abstract

C-peptide concentrations in the cord blood of 29 macrosomic neonates born of nondiabetic mothers were higher than in 23 control infants whose birth weight was appropriate for gestational age, and there was a significant direct correlation between birth weight and C-peptide concentration. Six of the macrosomic infants studied (20%) had hypoglycemia in the first 24 hours of life, compared with none of the infants born with appropriate weight. We conclude that chronic fetal hyperinsulinemia may be one of the causes of macrosomia and neonatal hypoglycemia in infants of nondiabetic mothers.
