Brief summary
The purpose of this study are: * Assess the impact of an intervention to the adoption of healthy lifestyles among pregnant women at high risk of gestational diabetes mellitus on: * weight gain in pregnancy * the levels of maternal and fetal adipokines and * glycemic control maternal and fetal. * Determine whether the adoption of healthy lifestyles in pregnancy is associated with epigenetic changes that influence the levels of adipokines and glucose regulation during pregnancy and in newborns.
Interventions
