Weight-related and analytical maternal factors in gestational diabetes to predict birth weight and cord markers of diabetic fetopathy.

AbstractObjective: The objective was to determine the value of clinical and analytical maternal factors to predict birth weight and umbilical cord biochemical markers of diabetic fetopathy.Methods: Prospective evaluation of gestational diabetes pregnancies (n = 50). Maternal weight-related clinical and analytical factors were collected during pregnancy. After birth, an umbilical cord sample was taken.Results: Univariate linear regression analysis showed relationship between maternal weight, glycated hemoglobin (HbA1c) and insulin-like growth factor 1 (IGF1) with birth weight percentile. A significant association was found between maternal weight and cord insulin and C-peptide. Maternal HbA1c, leptin and insulin during pregnancy showed a positive linear association to cord leptin, insulin and C-peptide. In multivariate analysis models, final maternal BMI showed an independent positive association with cord C-peptide.Conclusions: Maternal weight-related and analytical parameters show diagnostic value to bir...
