研究表明，久坐行为和体力活动不仅对儿童的身心健康而且对学业成绩都有潜在影响。然而，研究仅关注久坐行为或体力活动。检查这两种行为对学业成绩的联合影响，可以详细了解这些行为与儿童学业成绩的关系。本研究调查了日本儿童体力活动和屏幕时间与学业成绩的联合纵向关联。对261名7-10岁儿童的屏幕时间和体力活动进行了评估，并在一年后评估了他们的学业表现。使用多变量逻辑回归分析来检查屏幕时间和身体活动与根据人口特征调整的学业成绩的联合关联。与屏幕时间长、体力活动少的儿童相比，屏幕时间少、体力活动少的儿童获得高学业成绩的几率高出 2.04（95% 置信区间：1.11-3.78）倍，而屏幕时间短、体力活动多的儿童的学业成绩高的几率高出 2.75（1.17-6.43）倍（男孩；4.12（1.19-14.24））。无论身体活动水平如何，屏幕时间少与一年后的高学业成绩相关。
Studies have shown the potential effects of sedentary behavior and physical activity on not only physical and mental health but also academic performance in children. Nevertheless, studies have only focused on either sedentary behavior or physical activity. Examining the joint effects of both behaviors on academic performance provides detailed insights into the patterns of these behaviors in relation to children's academic achievement. The present study investigated the joint longitudinal associations of physical activity and screen time with academic performance among Japanese children. The screen time and physical activity of 261 children aged 7-10 years were assessed, and their academic performance was evaluated one year later. Multivariate logistic regression analysis was used to examine the joint associations of screen time and physical activity with academic performance adjusted for demographic characteristics. Children with low screen time and physical activity had 2.04 (95% confidence interval: 1.11-3.78) times greater odds of having high academic performance compared to children with high screen time and low physical activity, while children with low screen time and high physical activity had 2.75 (1.17-6.43) times greater odds (boys; 4.12 (1.19-14.24)). Low screen time was related to high academic performance after one year, regardless of the physical activity level.
