  Purpose

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.

Primary Outcome Measures:
  • Weight change during pregnancy [ Time Frame: Weeks 12, 24, 36 of gestation ]

Secondary Outcome Measures:
  • Levels of maternal and fetal adipokines [ Time Frame: Weeks 12, 24 of gestation and at delivery (in cord blood) ]
  • Maternal and fetal glycemic control [ Time Frame: 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. [ Time Frame: 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. [ Time Frame: throughout the study ]
    Documentation will be collected about appreciation of the participants and attendance.

Arms Assigned Interventions
Active Comparator: Control group
In addition to the usual monitoring of pregnancy, this group will receive information about the recommended weight gain during pregnancy and an evaluation about of their nutritional and physical activity habits.
Behavioral: Control group
Evaluation of nutritional and physcial activity habits
Experimental: Intervention group

This group will receive a regular monitoring by health professionals (nutritionist and kinesiologist) who will ensure nutritional changes and physical activity necessary to secure the adoption of a healthy lifestyle and could participate to a physical activity group session once a week until week 36 of gestation.

The intervention include:

A nutritional counseling every 2 weeks by a nutritionist until week 36 of gestation; a physical activity group session once a week lead by a kinesiologist until week 36 of gestation; 2 sessions of physical activity counseling (weeks 12 and 24).

Behavioral: Healthy lifestyle counseling
Nutritionnal and physical activity counseling and physical activity session group
Other Name: Intervention group
