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.
