    Abstract

    Our aim was to investigate the association
    between gestational weight gain (GWG) and postpartum
    weight retention (PWR) in pre-pregnancy underweight,
    normal weight, overweight or obese women, with emphasis
    on the American Institute of Medicine (IOM) recommendations.
    We performed secondary analyses on data based on
    questionnaires from 1,898 women from the ‘‘Smoke-free
    Newborn Study’’ conducted 1996–1999 at Hvidovre Hospital,
    Denmark. Relationship between GWG and PWR was
    examined according to BMI as a continuous variable and
    in four groups. Association between PWR and GWG
    according to IOM recommendations was tested by linear
    regression analysis and the association between PWR C
    5 kg (11 lbs) and GWG by logistic regression analysis.
    Mean GWG and mean PWR were constant for all BMI units
    until 26–27kg/m2. After this cut-off mean GWG and mean
    PWR decreased with increasing BMI. Nearly 40% of normal
    weight, 60% of overweight and 50% of obese women gained
    more than recommended during pregnancy. For normal
    weight and overweight women with GWG above recommendations
    the OR of gaining C 5 kg (11 lbs) 1-year
    postpartum was 2.8 (95% CI 2.0–4.0) and 2.8 (95% CI
    1.3–6.2, respectively) compared to women with GWG
    within recommendations. GWG above IOM recommendations
    significantly increases normal weight, overweight and
    obese women’s risk of retaining weight 1 year after delivery.
    Health personnel face a challenge in prenatal counseling
    as 40–60% of these women gain more weight than recommended
    for their BMI. As GWG is potentially modifiable,
    our study should be followed by intervention studies
    focusing on GW.
