Abstract
Objective
Poor diet quality has been observed in Nova Scotia children and youth, characterized by low intake from the traditional four food groups and a high intake from the Other Foods category. In this study, we addressed how household income and adherence to Canada’s Food Guide to Healthy Eating influenced weight status category in Nova Scotia children and youth.
Methods
During the 2005–06 school year, data were collected from 2,296 students and their parents, across Nova Scotia. Questionnaires and anthropometric measurements were obtained from grades 3, 7 and 11 students. The grade 3 students were excluded from the dietary intake assessment. The information collected from the online 24-hour food recalls and food frequency questionnaires were analyzed for adherence to Canada’s Food Guide to Healthy Eating recommendations. A general linear model was employed to examine the relationships between household income, food group and weight status category.
Results
Overall adherence to Canada’s Food Guide to Healthy Eating was low among grades 7 and 11 students. Fewer servings from Grain Products, Milk Products and Vegetables and Fruit were observed in at risk of overweight and overweight students. At risk of overweight and overweight were significantly related to lower household income in grades 3 and 11. Our results show that the rates of overweight in Nova Scotia students are double those reported by the 2004 Canadian Community Health Survey.
Conclusion
Household income and dietary intake play significant roles in weight status among Nova Scotia children and youth.
Key words: Child nutrition sciences, overweight, income
Résumé
Objectif
Les enfants et les adolescents de la Nouvelle-Écosse ont une alimentation de mauvaise qualité, caractérisée par de faibles apports en aliments des quatre groupes classiques et un apport élevé en aliments des autres catégories. Notre étude porte sur l’influence du revenu des ménages et du respect des recommandations du Guide alimentaire canadien pour manger sainement sur le statut pondéral des enfants et des adolescents néo-écossais.
Méthode
Pendant l’année scolaire 2005–2006, nous avons recueilli des données auprès de 2 296 élèves et de leurs parents dans toute la Nouvelle-Écosse. Nous avons administré des questionnaires et pris les mesures anthropométriques d’élèves de la 3e, de la 7e et de la 11e année. Les élèves de 3e année ont été exclus de l’évaluation initiale des apports nutritionnels. Les données (provenant de feuilles de rappel des aliments ingérés pendant les 24 dernières heures et de questionnaires sur la fréquence de consommation des produits alimentaires) ont été analysées en fonction des recommandations du Guide alimentaire canadien pour manger sainement. Un modèle linéaire général a servi à l’examen des liens entre le revenu du ménage, les groupes d’aliments et la catégorie de statut pondéral.
Résultats
En général, les préceptes du Guide alimentaire canadien pour manger sainement étaient peu respectés chez les élèves de 7e et de 11e année. Les élèves qui faisaient de l’embonpoint (ou qui étaient à risque d’en faire) consommaient moins de portions de produits céréaliers, de produits laitiers et de légumes et fruits. L’embonpoint et le risque d’embonpoint étaient liés de façon significative à un revenu inférieur du ménage chez les élèves de 3e et de 11e année. Les taux d’embonpoint des élèves de la Nouvelle-Écosse étaient le double de ceux déclarés dans l’Enquête sur la santé dans les collectivités canadiennes de 2004.
Conclusion
Le revenu du ménage et l’apport nutritionnel jouent un rôle important dans le statut pondéral des enfants et des adolescents en Nouvelle-Écosse.
Mots clés: sciences de la nutrition de l’enfant, embonpoint, revenu
