Food knowledge is associated with fruit and vegetable intake among children aged 9–14 years in Ontario, Canada
Notice bibliographique
Résumé
It is widely accepted that the consumption of fruits and vegetables (FV) is important for maintaining overall health. Food-based dietary guidelines and national recommendations such as Canada's Food Guide (2019) encourage the frequent intake of FV, but despite such recommendations, the intake of FV by school-age children in Canada remains suboptimal Attempts to improve dietary quality have had modest success The Canadian government has recently prioritised the development of strategies that improve healthy eating early in childhood To inform public health professionals, policy makers, and educators about the factors associated with inadequate intake of FV, the objectives of this study were to a) quantify the intake of FV as reported by elementary school children in Ontario, Canada, and b) investigate factors associated with FV consumption, including food knowledge, the food environment, socioeconomic status, and other sociodemographic characteristics. In 2017-19, a cross-sectional survey was administered to 2,443 students aged 9 to 14 years, at 60 urban and rural schools across Southwest Ontario, Canada. The self-report survey included 124 questions under four main topics: sociodemographic information, eating habits, nutrition and food knowledge, and food preferences. A parent survey was used to validate the sociodemographic variables reported by students. FV intake was obtained from two multiple component food frequency questions, developed by registered dietitians. Forty-six individual questions assessed food knowledge in the student survey; a total score was obtained by adding the correct responses. Multiple regression was used to analyse children's intake of FV with various predictor variables, including food knowledge, sociodemographic characteristics, and the food environment. The mean intake of fruits and vegetables reported by participants was 2.6 (SD 1.1) and 2.4 (SD 1.2) servings/day, respectively. A total FV intake below WHO guidelines (5 servings/day) was reported by 40.7% of respondents. Mean total knowledge score was 29.2 (SD 7.1) out of a possible 46 points (63.5% correct responses). Knowledge score ( = 0.257, p < 0.001) and child age (= -0.072 p = 0.001) significantly predicted higher reported intake of FV. This study shows that FV intake among this sample of school-aged children is low, and increased intake is associated with higher food knowledge. To encourage healthy eating, school-based food and nutrition programmes of sufficient duration, that incorporate multiple components and emphasise food knowledge have value among this young population.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
