研究背景儿童期较高的身体质量指数（BMI）与较低的学业成绩相关。目的探讨儿童期BMI与教育程度之间的潜在联系。方法使用来自Avon家长和儿童前瞻性队列研究的数据（N= 6949），我们评估了11.7岁时的BMIz分数与16岁时的教育程度（普通中等教育证书[GCSE]结果）之间的关联。抑郁症状，外化行为，欺凌和学校的乐趣被认为是潜在的调解人。结果较高的BMIz分数与较低的GCSE分数相关（女性β= −3.47 95%CI −5.54，男性β= − 1.41 95%CI −6.73，−1.94）。欺负、外化症状、抑郁症状和学校享受在女性中占41.9%，在男性中占23.3%。在男性中，中介的证据很弱（所有间接效应的置信区间均为零）。在女性和男性，大部分的调解是由externalizing symptoms.ConclusionsThe有害影响较高的BMI对教育程度的部分原因是由externalizing行为，特别是在女性。支持行为问题的干预措施可能有助于体重较高儿童的学业成绩。
BackgroundHigher body mass index (BMI) in childhood is associated with lower academic achievement.ObjectiveTo explore potential pathways linking childhood BMI with educational attainment.MethodsUsing data from the Avon Longitudinal Study of Parents and Children prospective cohort study (N= 6949), we assessed the association between BMIz‐scores at 11.7 years and educational attainment at 16 (General Certificate of Secondary Education [GCSE] results). Depressive symptoms, externalizing behaviours, bullying and school enjoyment were considered as potential mediators. Mediators were examined individually and jointly using sequential causal mediation.ResultsHigher BMIz‐scores were associated with lower GCSE scores (femalesβ= −3.47 95% CI −5.54, −1.41 malesβ= −4.33 95% CI −6.73, −1.94). Together, bullying, externalizing symptoms, depressive symptoms and school enjoyment mediated 41.9% of this association in females, and 23.3% in males. In males, evidence for mediation was weak (confidence intervals for all indirect effects spanned the null). In both females and males, most of the mediation was driven by externalizing symptoms.ConclusionsThe detrimental effect of higher BMI on educational attainment appears to be partly explained by externalizing behaviours, particularly in females. Interventions to support behavioural problems may help the academic achievement of children with a higher body weight.
