Intervention to Promote Changes of Healthy Lifestyle (Physical Activity and Nutrition) During Gestation

Not Applicable

Completed

• Conditions: Excessive Weight Gain During Pregnancy; Gestational Diabetes

• Registration Number: NCT01782105
• Lead Sponsor: Université de Sherbrooke

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.

Weight change during pregnancy	Weeks 12, 24, 36 of gestation

Secondary Outcome Measures

Name	Time	Method
Levels of maternal and fetal adipokines	Weeks 12, 24 of gestation and at delivery (in cord blood)
Maternal and fetal glycemic control	Weeks 12, 24 of gestation and at delivery	Results of glucose tolerance test (50g and 75g)
Determine whether the adoption of healthy lifestyle in pregnancy is associated with epigenetic changes that influence the levels of adipokines and glucose regulation during pregnancy and in newborns.	Weeks 12, 24 of gestation and at delivery (cord blood)
Optimize the intervention before measuring its impact on the prevention of gestational diabetes mellitus on a larger scale.	throughout the study	Documentation will be collected about appreciation of the participants and attendance.
