Establishing early healthy eating and physical activity behaviours is critical in supporting children's long-term health and well-being. The objective of the current paper was to examine the association between health behaviours and academic performance in elementary school students in a school board in Nova Scotia, Canada.
Our population-based study included students in grades 4-6 across 18 schools in a rural school board. Diet and physical activity were assessed through validated instruments. Academic performance measures were obtained from the school board for Mathematics and English Language Arts (ELA). Associations between health behaviours and academic performance were assessed using multilevel logistic regression.
Students with unhealthy lifestyle behaviours were more likely to have poor academic performance for both ELA and Mathematics compared to students with healthy lifestyle behaviours; associations were statistically significant for diet quality, physical activity, sugar-sweetened beverage consumption for ELA; and breakfast skipping, not being physically active at morning recess, and not being physically active after school for Mathematics. The effects of diet and physical activity were independent of each other and there was no interaction between the two exposures.
Our findings suggest that support for healthy behaviours may help to improve academic outcomes of students.
建立早期健康的饮食和身体活动行为对于支持儿童的长期健康和幸福至关重要。本文的目的是研究加拿大新斯科舍省一个学区的小学生健康行为与学业成绩之间的关联。
我们基于人群的研究纳入了一个农村学区18所学校的4至6年级学生。通过经过验证的工具评估饮食和身体活动。学业成绩指标从学区获取，涉及数学和英语语言艺术（ELA）。使用多水平逻辑回归评估健康行为与学业成绩之间的关联。
与具有健康生活方式行为的学生相比，具有不健康生活方式行为的学生在ELA和数学方面更有可能学业成绩不佳；对于ELA，饮食质量、身体活动、含糖饮料消费之间的关联具有统计学意义；对于数学，不吃早餐、上午课间休息时不进行身体活动以及放学后不进行身体活动之间的关联具有统计学意义。饮食和身体活动的影响相互独立，且两种暴露之间没有交互作用。
我们的研究结果表明，对健康行为的支持可能有助于提高学生的学业成绩。
