NCT01623934

Brief Summary

This study includes 2 phases. During phase 1, pregnant women are followed over the course of pregnancy. The phase 2 is a follow-up of the mother-child dyad at 3, 5 and 10-12 year after delivery. The purpose of this phase 1 is to :

  • assess the contribution and interactions of adipokines in the development of insulin resistance during pregnancy and gestational diabetes;
  • assess levels of maternal adipokines as determinants of development and fetal growth;
  • determine the genetic variations that influence levels of adipokines and glucose regulation during pregnancy and in newborns. The purpose of this phase 2 is to:
  • identify DNA methylation variations at birth that are predictive of childhood overweight/obesity.
  • identify maternal characteristics associated with DNA methylation variations predictive of childhood overweight/obesity.
  • establish whether the loci predictive of childhood overweight/obesity at birth are still differentially methylated at 5 years of age (samples collected at 5 years of age).
  • identify DNA methylation variations at birth that are predictive of childhood neurodevelopment problems at 3, 5 and 10 years of age.
