Interventions to improve dietary quality and intake of fruits and vegetables (FV) among Canadian children have had modest success, and it has been suggested that food knowledge could be key to improvement. Programs have been criticized for insufficiently connecting food knowledge with food skills and decision making about dietary intake. The objective of this study was to investigate factors associated with FV consumption by elementary school children, aged 9-14 years, in Ontario, Canada, including food knowledge, socioeconomic status, sociodemographic characteristics, and the food environment. In 2017-2019, a cross-sectional survey was administered to 2443 students at 60 elementary schools across Southwestern Ontario (SWO), Canada. A parent survey was used to validate self-reported sociodemographic variables. The mean intake of FV reported by these participants was 2.6 (SD 1.1) and 2.4 (SD 1.2) servings/day, respectively. A FV intake below WHO guidelines was reported by 40.7% of respondents. Knowledge score, child age, and parent employment status significantly predicted higher reported intake of FV. This study shows that FV intake among this population group is low, and increased intake is associated with higher food knowledge. To encourage healthy eating, school-based food and nutrition programs that incorporate multiple components and emphasize food literacy are needed.
旨在改善加拿大儿童饮食质量以及水果和蔬菜(FV)摄入量的干预措施取得的成效有限,有人认为食物知识可能是改善的关键。一些项目因未充分将食物知识与食物技能以及饮食摄入决策联系起来而受到批评。本研究的目的是调查加拿大安大略省9至14岁小学生FV消费的相关因素,包括食物知识、社会经济地位、社会人口特征和食物环境。2017年至2019年,对加拿大安大略省西南部(SWO)60所小学的2443名学生进行了横断面调查。通过家长调查来验证自我报告的社会人口变量。这些参与者报告的FV平均摄入量分别为每天2.6份(标准差1.1)和2.4份(标准差1.2)。40.7%的受访者报告其FV摄入量低于世界卫生组织的指导标准。知识得分、儿童年龄和家长就业状况显著预测了较高的FV报告摄入量。本研究表明,该人群的FV摄入量较低,但摄入量增加与较高的食物知识相关。为鼓励健康饮食,需要开展包含多个组成部分并强调食物素养的校本食品和营养项目。
