Dietary Intake of Nova Scotia Youth: In Grades 7 and 11

Publication: Canadian Journal of Dietetic Practice and Research
13 February 2012

Abstract

Purpose: We examined dietary intakes among Nova Scotia youth, and analyzed whether these intakes met existing dietary guidelines.
Methods: Data from 1469 students in grades 7 and 11 from randomly selected schools were collected via a web-based dietary assessment tool, including a 24-hour recall. Nutrient analysis products were subjected to descriptive and inferential statistical analyses.
Results: Reported dietary intakes across sexes and grades showed the vast majority of youth did not meet minimum recommendations for fibre (96% to 98%) or vegetable and fruit servings (83.3% to 90.7%). Girls in grade 11 reported greater intakes of folate and lower intakes of saturated fat, and were less likely to report iron intakes at or above the Estimated Average Requirement than were grade 7 girls. Across ages, more than 75% of girls reported low calcium and folate intakes. Boys in both grades reported consuming more energy than did girls, and older boys reported consuming more than did younger boys. Foods outside the four main food groups contributed about 25% of total reported energy intake. Students in grade 7 consumed pop, salty snacks, and french fries more frequently than did students in grade 11.
Conclusions: Adolescents’ self-reported dietary intakes may not meet current dietary recommendations. Continued efforts are needed to develop innovative strategies to ensure healthy eating patterns.

Résumé

Objectif: Nous avons examiné les apports alimentaires de jeunes de la Nouvelle-Écosse et analysé si ces apports satisfaisaient aux recommandations alimentaires en vigueur.
Méthodes: Des données obtenues de 1469 élèves de 7e et de 11e année choisis aléatoirement dans les écoles sélectionnées ont été recueillies à l’aide d’un outil en ligne d’évaluation de l’alimentation comprenant un rappel alimentaire de 24 heures. Les résultats de l’analyse des nutriments ont été soumis à des analyses statistiques inférentielles et descriptives.
Résultats: Les apports alimentaires rapportés, sexes et niveaux scolaires confondus, ont montré que la grande majorité des jeunes ne consommaient pas la quantité minimale recommandée de fibres (96 % à 98 %) ou de légumes et fruits (83,3 % à 90,7 %). Les filles de 11e année ont rapporté un plus grand apport en folate et un plus faible apport en gras saturés, en plus d’être moins susceptibles de rapporter un apport en fer équivalent ou supérieur au besoin moyen estimatif comparativement aux filles de 7e année. Globalement, pour tous les âges, plus de 75 % des filles ont rapporté de faibles apports en calcium et en folate. Les garçons des deux niveaux ont rapporté consommer davantage d’énergie que les filles, et les garçons plus âgés ont rapporté une plus grande consommation que les plus jeunes. Les aliments ne faisant pas partie des quatre principaux groupes alimentaires comptaient pour environ 25 % de l’apport énergétique total rapporté. Les élèves de 7e année consommaient des boissons gazeuses, des collations salées et des frites plus souvent que les élèves de 11e.
Conclusions: Les apports alimentaires rapportés par les adolescents pourraient ne pas satisfaire aux recommandations alimentaires en vigueur. Des efforts constants doivent être déployés afin de mettre sur pied des stratégies innovatrices qui permettront d’assurer une saine alimentation.
