Abstract

Purpose: Pre-conception weight gain and postpartum weight retention may contribute to women’s increased risk of developing overweight/obesity; however, weight history data that would permit an examination of this hypothesis have been lacking. Our objective was to describe the weight history of pregnant overweight women and their families.
Methods: Between 16 and 20 weeks of gestation, 107 overweight pregnant women (21 Aboriginal, including 20 First Nations and oneMétis, and 86 non-Aboriginal) completed a weight history questionnaire.
Results: Average adult usual body weight (UBW) corresponded to a bodymass index (BMI) of 29.2 ± 5.5 kg/m2 (overweight). Average pre-pregnancy BMI (33.0 ± 6.6 kg/m2) increased into the obesity category.Over two-thirds of subjects reported an unstable UBW. A large proportion ofmultiparous subjects had retained weight after pregnancy. The average weight retained was 12.7 ± 9.4 kg, and it accounted for almost all of the weight change from UBW.
Conclusions: Weight history questionnaire results showed that pre-conception weight fluctuations and postpartum weight retention are significant problems for many overweight/ obese women. Health care professionals can use this information for early prenatal through postpartum interventions designed to help overweight/obese women achieve an appropriate pregnancy weight and prevent sustained postpartum weight retention.

Résumé

Objectif: Le gain de poids avant la conception et la rétention de poids postpartum peuvent contribuer à augmenter le risque de développer un surpoids ou de l’obésité, mais peu de données existent sur l’histoire pondérale pour vérifier cette hypothèse. Notre objectif était donc de décrire l’évolution du poids corporel chez des femmes enceintes présentant un surpoids et leurs familles.
Méthodes: Au total, 107 femmes enceintes présentant un surpoids (21 Aborigènes, soit 20 des Premières Nations et uneMétis, et 86 non-Aborigènes) ont rempli un questionnaire d’histoire pondérale entre 16 et 20 semaines de grossesse.
Résultats: Le poids corporel adulte habituelmoyen (PCH) des participantes correspondait à un indice demasse corporelle (IMC) de 29,2 ± 5,5 kg/m2, dénotant un surpoids. Leur IMC moyen avant la grossesse (33,0 ± 6,6 kg/m2) les avait fait passer dans la catégorie « obésité ». Plus des deux tiers des sujets ont signalé une instabilité de leur PCH. Une forte proportion des sujets multipares avait conservé un surpoidsmoyen de 12,7 ± 9,4 kg après la grossesse, et ce surpoids représentait presque toute la différence de poids par rapport à leur PCH.
Conclusions: Les résultats recueillis à l’aide des questionnaires d’histoire pondérale ont montré que les fluctuations de poids avant la conception et la rétention de poids postpartum sont des problèmes importants pour de nombreuses femmes présentant un surpoids ou obèses. Les professionnels de la santé peuvent utiliser cette information dans leurs interventions préet post-natales pour aider les femmes présentant un surpoids ou obèses à atteindre un poids approprié durant la grossesse et prévenir la rétention de poids postpartum.
