Some studies have found positive associations between physical fitness and academic achievements. Pupils' academic achievements should indicate scholastic abilities to commence a post-compulsory education. However, the effect magnitude of physical fitness and academic achievements on commencement in post-compulsory education is unknown. We examined the pathways between physical fitness and academic achievement on pupils' commencement in post-compulsory education.
This historical cohort study followed 530 girls and 554 boys from the Danish municipality of Aalborg in the period 2008-2014, 13 to 15 years old in 2010. Physical fitness was assessed through a watt-max cycle ergometer test represented as VOmax (mL·kg·min). Academic achievement, commencement status and information on covariates were obtained from Danish nationwide registers. Causal inference based mediation analysis was used to investigate the indirect and direct pathways by separating the total effect of physical fitness on post-compulsory education commencement.
Adjusting for sex, age, ethnicity and socioeconomic status, the overall mediation analysis showed an odds ratio (OR) of 1.87 (95% confidence interval (CI): 1.30; 2.73) for the total effect, corresponding to an increase in odds of post-compulsory education commencement when the physical fitness was increased by 10 units of VOmax. The separated total effect showed a natural direct OR of 1.36 (95% CI: 0.93; 1.98) and a natural indirect (i.e., through academic achievement) OR of 1.37 (95% CI: 1.20; 1.57). Thus, 51% (95% CI: 27%; 122%) of the effect of physical fitness on post-compulsory education commencement was mediated through academic achievement.
Physical fitness had a positive effect on post-compulsory education commencement. A substantial part of this effect was mediated through academic achievement.
一些研究发现身体素质与学业成绩之间存在正相关。学生的学业成绩应表明其开始接受义务教育后教育的学术能力。然而，身体素质和学业成绩对义务教育后教育入学的影响程度尚不清楚。我们研究了身体素质和学业成绩对学生义务教育后教育入学的影响路径。
这项历史性队列研究追踪了2008年至2014年丹麦奥尔堡市的530名女孩和554名男孩，他们在2010年时年龄为13至15岁。通过以最大摄氧量（VO₂max，毫升·千克·分钟）表示的瓦特最大自行车测力计测试来评估身体素质。学业成绩、入学状态和协变量信息来自丹麦全国性登记册。基于因果推断的中介分析用于通过区分身体素质对义务教育后教育入学的总效应来研究间接和直接路径。
在对性别、年龄、种族和社会经济地位进行调整后，总体中介分析显示总效应的比值比（OR）为1.87（95%置信区间（CI）：1.30；2.73），这意味着当身体素质每增加10个VO₂max单位时，义务教育后教育入学的几率增加。分离后的总效应显示自然直接OR为1.36（95%CI：0.93；1.98），自然间接（即通过学业成绩）OR为1.37（95%CI：1.20；1.57）。因此，身体素质对义务教育后教育入学的影响中有51%（95%CI：27%；122%）是通过学业成绩介导的。
身体素质对义务教育后教育入学有积极影响。这种影响的很大一部分是通过学业成绩介导的。
