Previous studies have found that obesity could influence academic performance. The aim of this study was to systematically review the scientific evidence on the association between obesity and academic performance in school children. A systematic review of English articles was undertaken by using databases PubMed/Medline, ERIC, LILACS, SciELO and Web of Science. Cross-sectional and longitudinal studies examining the association between obesity and academic performance in children and adolescents, published between January 1990 and December 2016, were included. Risk of bias was assessed by using Strengthening the Reporting of Observational Studies in Epidemiology. Thirty-four studies (23 cross-sectional and 11 longitudinal) matched all inclusion criteria and were included. Seven studies were classified as low risk of bias, 23 as medium risk and four as high risk. After controlling for covariates such as socio-economic status, parental education and physical activity, the association between obesity and academic performance becomes uncertain for most of the studies (55.9%). Therefore, at present, there is insufficient evidence to support a direct link between obesity and poor academic performance in school age children. In order to clarify this issue, we need more longitudinal studies with adequate sample sizes and that control for potential confounders.
先前的研究已经发现肥胖可能会影响学业成绩。本研究旨在系统地回顾有关肥胖与在校儿童学业成绩之间关联的科学证据。通过使用数据库 PubMed/Medline、ERIC、LILACS、SciELO 和 Web of Science 进行了英文文献的系统评价。纳入了研究肥胖与儿童和青少年学业成绩之间关联的横断面和纵向研究，这些研究发表于 1990 年 1 月至 2016 年 12 月之间。使用流行病学观察研究的强化报告标准评估了偏倚风险。符合所有纳入标准的 34 项研究（23 项横断面研究和 11 项纵向研究）被纳入分析。其中 7 项研究被归类为低风险，23 项为中风险，4 项为高风险。在控制了社会经济地位、父母教育程度和体力活动等协变量后，大多数研究（55.9%）肥胖与学业成绩之间的关联变得不确定。因此，目前尚无足够证据支持肥胖与学龄儿童学业成绩不佳之间存在直接联系。为了澄清这个问题，我们需要更多具有足够样本量并能控制潜在混杂因素的纵向研究。
