Conditions gestational diabetes, insulin resistance
Sponsor Université de Sherbrooke
Collaborator Fonds de la Recherche en Santé du Québec
Start date January 2010
End date January 2019
Trial size 1086 participants
Trial identifier NCT01623934, DG2A1


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 and 5 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 and 5 years of age.
