为了分析健康和肥胖的不同组成部分与学习成绩之间的关系，调整了智利样本中的性别、年龄、社会经济地位、地区和学校类型的分析。关于健康、肥胖和学习成绩的数据来自2011年智利八年级教育质量评估系统，其中包括18,746名受试者(49%为女性)。通过混杂因素调整的部分相关性来探索健康和肥胖成分之间的联系，以及学习成绩之间的联系。为了分析变量之间的关联性，进行了三个未调整和调整后的线性回归模型。当身体质量指数(BMI)和腰围身高比(WHR)被单独评估时，肥胖与学习成绩呈负相关。当BMI和WHR由联合创始人共同评估和调整时，WHR与学习成绩的关联比BMI更大，只有WHR的关联是正的。对于健康的组成部分，力量是与学习成绩最相关的变量。如果模型中包括肥胖和其他健康因素，那么心肺功能与学习成绩没有关联。健康和肥胖与学习成绩有关。与体重指数和心肺功能相比，腰臀比和力量与学习成绩的相关性更大。
To analyze the associations between different components of fitness and fatness with academic performance, adjusting the analysis by sex, age, socio-economic status, region and school type in a Chilean sample. Data of fitness, fatness and academic performance was obtained from the Chilean System for the Assessment of Educational Quality test for eighth grade in 2011 and includes a sample of 18,746 subjects (49% females). Partial correlations adjusted by confounders were done to explore association between fitness and fatness components, and between the academic scores. Three unadjusted and adjusted linear regression models were done in order to analyze the associations of variables. Fatness has a negative association with academic performance when Body Mass Index (BMI) and Waist to Height Ratio (WHR) are assessed independently. When BMI and WHR are assessed jointly and adjusted by cofounders, WHR is more associated with academic performance than BMI, and only the association of WHR is positive. For fitness components, strength was the variable most associated with the academic performance. Cardiorespiratory capacity was not associated with academic performance if fatness and other fitness components are included in the model. Fitness and fatness are associated with academic performance. WHR and strength are more related with academic performance than BMI and cardiorespiratory capacity.
