[C-peptide in cord blood from macrosomatic and low birth weight for gestational age newborns].
Forty-six newborn babies (11 macrosomic, 11 small-for-dates and 24 of normal weight) have been prospectively studied. The levels of C-peptide in the umbilical blood were determined and the results were statistically analyzed for relationships to several perinatal variables of the mother, newborn and placenta. A positive correlation between C-peptide levels and neonatal weight, newborn ponderal index and maternal weight-gain during gestation were observed. Some other variables strongly related to neonatal infant weight (maternal weight, net placental weight and placental volume) were independent of C-peptide levels.
