Counseling about Weight Gain Guidelines and Subsequent Gestational Weight Gain

Background: The purpose of this study was to investigate what percentage of postpartum women were informed about how much weight to gain during pregnancy, the accuracy of the weight gain recommendations based on the 2009 Institute of Medicine (IOM) gestational weight gain (GWG) recommendations and whether being informed was associated with greater likelihood of meeting the recommendations. Methods: This was a cross-sectional study of postpartum women interviewed in maternity recovery rooms at two large urban hospitals. Body mass index was obtained from medical records, and adherence to gestational weight gain guidelines was determined based on the 2009 IOM recommendations. Results: One hundred thirty four women with a mean pregravid body mass index of 28.0 kg/m² were studied. Sixty-seven percent of participants reported receiving weight gain recommendations. A greater percentage of healthy weight women (78.6%) reported being informed of a GWG recommendation than overweight (53.8%) or obese women (64.9%), (chi-squared=6.6, p=0.04). Of the women given information about gestational weight gain, 40 (54.8%) received GWG recommendations consistent with the IOM and 33 (45.2%) received discrepant information. The accuracy of the GWG recommendation varied based on weight status. Women of healthy weight were much more likely to be given information in accordance with the IOM recommendations (86.8%) than women who were overweight (12.5%) or obese (26.3%) (chi-squared=33.5, p<0.001). Meeting the IOM recommendations did not differ depending on whether women were told how much weight to gain during pregnancy. Conclusions: Women who are overweight or obese are less likely to be informed about weight gain recommendations than healthy weight women, and nearly half of women receive information inconsistent with the IOM recommendations. There may be a need for further practitioner education on GWG recommendations and increased patient counseling to help promote healthy weight gain during pregnancy.
