This study aims to examine the independent and combined associations of 24-Hour Movement Guidelines for physical activity, screen time, and sleep duration with academic achievement in adolescent males and females.
Cross-sectional study.
1290 Spanish adolescents (565 females), aged 11 to 16 years (13.06 ± 0.84), participated in this study. Self-reported physical activity, screen time, and sleep duration questionnaires were assessed. Academic achievement was calculated as an average score of the adolescents'' grades in first language (Spanish), first foreign language (English), and mathematics subjects. A multiple linear regression model was used to examine the association between meeting 24-Hour Movement Guidelines and academic achievement. Covariates included age, sex, socioeconomic status, body mass index, and cardiorespiratory fitness.
Not meeting any of the three 24-Hour Movement Guidelines was associated with lower academic achievement in the whole sample (p < 0.001). Meeting physical activity and sleep duration guidelines, both independently and together, was associated with higher academic achievement in the whole sample (p < 0.001). Meeting at least two recommendations was associated with higher academic achievement in males (p < 0.01). However, trend analysis revealed that participants who met two or three recommendations had higher academic achievement compared to those who met one or none of these recommendations (p < 0.05). All these results were similar for males and females.
Our findings suggest the importance of promoting more than one 24-Hour Movement Guidelines, mainly physical activity and sleep duration, which seems to contribute positively to increased academic performance in adolescents.
本研究旨在探讨青少年男性和女性中，24 小时身体活动、屏幕时间和睡眠时间指南的独立和联合关联与学业成绩的关系。
横断面研究。
1290 名西班牙青少年（565 名女性），年龄在 11 至 16 岁（13.06±0.84），参与了这项研究。自我报告的身体活动、屏幕时间和睡眠时间问卷进行了评估。学业成绩计算为青少年第一语言（西班牙语）、第一外语（英语）和数学科目的平均成绩。使用多元线性回归模型来检验符合 24 小时运动指南与学业成绩之间的关联。协变量包括年龄、性别、社会经济地位、体重指数和心肺适能。
不符合任何三项 24 小时运动指南的青少年，其整体学业成绩较低（p<0.001）。独立和共同符合身体活动和睡眠持续时间指南与整体样本的学业成绩较高相关（p<0.001）。符合至少两项建议的青少年，其学业成绩较高（p<0.01）。然而，趋势分析表明，与仅符合一项或一项都不符合这些建议的青少年相比，符合两项或三项建议的青少年的学业成绩更高（p<0.05）。这些结果在男性和女性中均相似。
我们的研究结果表明，促进超过一项 24 小时运动指南的重要性，主要是身体活动和睡眠持续时间，这似乎有助于提高青少年的学业成绩。
