Background: Preventing excessive weight gain during pregnancy is potentially important in the
prevention of overweight and obesity among women of childbearing age. However, few
intervention studies aiming at weight management during pregnancy have been performed and
most of these interventions were not as successful as expected. In this paper the design of the New
Life(style) study is described as well as the content of the individually tailored intervention program,
which focuses on controlling weight development during pregnancy.

Methods: The effectiveness of the New Life(style) intervention program versus usual care by
midwives is evaluated in a randomised controlled trial. Women who expect their first child and visit
one of the participating midwifery practices are included. The intervention is standardised in a
protocol and executed by trained counsellors with the women who are randomised in the
intervention group. During 5 sessions – at 18, 22, 30 and 36 weeks of pregnancy and at 8 weeks
postpartum – individual weight gain is discussed in relation to weight gain guidelines for pregnant
women of the American Institute of Medicine. Counsellors coach the women to maintain or
optimise a healthy lifestyle, in a period of drastic physical and mental changes. Data is collected at
15, 25, 35 weeks of pregnancy and at 6, 26, and 52 weeks after delivery. Primary outcome measures
are body weight, BMI, and skinfold thickness. Secondary outcome measures include physical
activity, nutrition and blood levels of factors that are associated with energy homeostasis.

Discussion: Results of the current RCT will improve the knowledge of determinants of weight
gain during pregnancy, weight retention after childbirth and of the effectiveness of the intervention
program that is described. Caregivers and researchers in the field of health promotion are offered
more insight in specific elements of the New Life(style) intervention program.
