An assistant will perform the anthropometrical measurements and collect the blood samples at 15, 25, 35 weeks of pregnancy and at 7, 25, 51 weeks after delivery in the midwife practice to measure the following outcome measures:<br>
Weight and BMI (change): height is measured in bare feet with a portable height scale with a wide measuring slide and a heel plate. Both weight and height will be measured twice, and the mean value of the two measurements will be computed. Calibrated scales are used to determine weight while participants are only wearing light clothing (e.g. underwear) and no shoes.
Achtergrond van het onderzoek
Background:
For women, pregnancy is an independent risk factor for developing overweight. Previous studies describe an average weight retention of 2-3 kg, 6 to 12 months after delivery. Losing this "extra" weight after pregnancy proves to be difficult. Weight gain during pregnancy is the most important determinant of postpartum weight retention.
Methods:
An RCT is performed to study the effect of an individually tailored intervention program on weight gain during pregnancy and postpartum weight retention. The main focus of this program is to help women to gain weight within guidelines for weight development during pregnancy, which are developed by the Institute of Medicine (IOM, 1990). In the intervention group, a counsellor surveys individual weight development during five sessions (18, 22, 30 and 36 weeks of pregnancy and 8 weeks postpartum) . Furthermore, personal lifestyle is discussed in order to be able to control individual weight development. Data are collected in the control and intervention group at 15, 25, and 35 weeks of pregnancy and at 8, 26, and 52 weeks after delivery by means of questionnaires and anthropometric measurements.
Conclusion:
Preventing excessive weight gain during pregnancy is important in the prevention of overweight and obesity among women of childbearing age. Caregivers and researchers in the field of health promotion are offered more insight in specific elements of the New Life(style) intervention program for pregnant women.
Doel van het onderzoek
Weight gain during pregnancy is the most important determinant of postpartum weight retention. In this study, the effect of an individually tailored intervention program is assessed on weight gain during pregnancy. The main focus of this program is to help women to gain weight within guidelines for weight development during pregnancy, which are developed by the Institute of Medicine (IOM, 1990). We expect that gaining weight within the guidelines has a positive effect on weight retention postpartum.
