背景：虽然营养对健康和学习成绩的影响经常被引用，但很少有研究调查饮食质量对儿童学习成绩的影响。这项研究考察了整体饮食质量和学习成绩之间的关系。方法：2003年，加拿大新斯科舍省5200名五年级学生及其父母接受了“儿童生活方式和学校表现研究”的调查。饮食摄入、身高、体重和社会人口变量的信息与省级标准化识字评估的结果相关联。采用国际日粮质量指数对日粮质量进行综合评价。采用多水平回归方法检验饮食质量指标与学业成绩之间的关系，同时调整了父母和居住社区的性别和社会经济特征。结果：在饮食质量的各种指标中，观察到与学习成绩的关联。总体饮食质量下降的学生更有可能在评估中表现不佳。女孩比男孩表现得更好，来自社会经济优势家庭的孩子也是如此。上更好的学校和生活在富裕社区的孩子也表现得更好。结论：这些发现证明了饮食质量与学习成绩之间的联系，并确定了具体的饮食因素，有助于这种联系。此外，这项研究支持更广泛地实施和投资有效的学校营养计划，这有可能改善学生获得健康食品的选择，饮食质量，学习成绩，并从长远来看，健康。
BACKGROUND: Although the effects of nutrition on health and school performance are often cited, few research studies have examined the effect of diet quality on the academic performance of children. This study examines the association between overall diet quality and academic performance.METHODS: In 2003, 5200 grade 5 students in Nova Scotia, Canada, and their parents were surveyed as part of the Children's Lifestyle and School-performance Study. Information on dietary intake, height, and weight and sociodemographic variables were linked to results of a provincial standardized literacy assessment. Diet Quality Index-International was used to summarize overall diet quality. Multilevel regression methods were used to examine the association between indicators of diet quality and academic performance while adjusting for gender and socioeconomic characteristics of parents and residential neighborhoods.RESULTS: Across various indicators of diet quality, an association with academic performance was observed. Students with decreased overall diet quality were significantly more likely to perform poorly on the assessment. Girls performed better than boys as did children from socioeconomically advantaged families. Children attending better schools and living in wealthy neighborhoods also performed better.CONCLUSIONS: These findings demonstrate an association between diet quality and academic performance and identify specific dietary factors that contribute to this association. Additionally, this research supports the broader implementation and investment in effective school nutrition programs that have the potential to improve student access to healthy food choices, diet quality, academic performance, and, over the long term, health.
