Outcomes
Primary Outcomes
Changes in body weight (kg) between visits.
Time Frame: Visit 1 (2 weeks postpartum, visit 2 (6 months postpartum) and visit 3 (post weaning ~15 months postpartum)
Measured in light clothing without shoes. Together with measured height (m) will be used to calculate Body Mass Index.
Changes in markers of lipid- and glucose metabolism between visits.
Time Frame: Visit 1 (2 weeks postpartum, visit 2 (6 months postpartum) and visit 3 (post weaning ~15 months postpartum)
Measured in mmol/l: total cholesterol, low-density lipoprotein, high-density lipoprotein, triglycerides and glucose In percentage: HbA1c In pmol/l: insulin.
Secondary Outcomes
- Changes in blood pressure, diastolic and systolic between visits(Visit 1 (2 weeks postpartum, visit 2 (6 months postpartum) and visit 3 (15 months postpartum))
- Changes in body composition (fat free mass in kg and fat mass in kg) between visits.(Visit 1 (2 weeks postpartum, visit 2 (6 months postpartum) and visit 3 (post weaning ~15 months postpartum))
- Changes in lipid subclasses (mmol/l), lipoprotein size (nm) and apolipoproteins between visits(Visit 1 (2 weeks postpartum, visit 2 (6 months postpartum) and visit 3 (post weaning ~15 months postpartum))
- Changes in waist and hip (cm) circumference between visits(Visit 1 (2 weeks postpartum, visit 2 (6 months postpartum) and visit 3 (post weaning ~15 months postpartum))
