虽然在青春期超重或肥胖可能会对学业成绩产生不利影响，但由于依赖于小样本量的横断面研究，未能考虑混杂因素以及缺乏对潜在介质的考虑，证据基础有限。本研究旨在解决这些局限性，并检查青少年肥胖和学业成绩之间的纵向关联。雅芳家长和儿童纵向研究调查了11岁时的体重状况与11岁、13岁和16岁时通过国家考试评估的学业成绩之间的关系。健康体重定义为体重指数（BMI）Z-评分<1.04;超重定义为BMI Z-评分1.04-1.63;肥胖定义为BMI Z-评分≥ 1.64。对5966名客观测量体重的参与者的数据进行了检查：71.4%为健康体重（1935名男性; 2325名女性），13.3%超重（372名男性; 420名女性）和15.3%肥胖（448名男性; 466名女性）。即使在控制了广泛的混杂因素后，11岁时肥胖的女孩在11岁、13岁和16岁时的学业成绩也低于健康体重的女孩。在男孩中，肥胖和学业成就之间的联系不太清楚。探讨了抑郁症状、智商（IQ）和女孩初潮年龄的潜在中介作用，但当包括混杂因素时，没有强有力的证据表明存在中介作用。对于女孩来说，青春期肥胖对5年后的学业成绩有不利影响。心理健康，智商和初潮年龄并没有调解这种关系，这表明需要进一步的工作，以了解潜在的机制。家长、教育和公共卫生政策制定者应考虑肥胖对该年龄组教育成果的广泛有害影响。
While being overweight or obese in adolescence may have detrimental effects on academic attainment, the evidence base is limited by reliance on cross-sectional studies with small sample sizes, failure to take account of confounders and lack of consideration of potential mediators. The present study aimed to address these limitations and examine longitudinal associations between obesity in adolescence and academic attainment. Associations between weight status at 11 years old and academic attainment assessed by national tests at 11, 13 and 16 years were examined in the Avon Longitudinal Study of Parents and Children. Healthy weight was defined as body mass index (BMI) Z-score <1.04; overweight as BMI Z-score 1.04–1.63; obesity as BMI Z-score ⩾1.64. Data from 5966 participants with objectively measured weight status were examined: 71.4% were healthy weight (1935 males; 2325 females), 13.3% overweight (372 males; 420 females) and 15.3% obese (448 males; 466 females). Girls obese at 11 years had lower academic attainment at 11, 13 and 16 years compared with those of a healthy weight, even after controlling for a wide range of confounders. Associations between obesity and academic attainment were less clear in boys. The potential mediating effects of depressive symptoms, intelligence quotient (IQ) and age of menarche in girls were explored, but when confounders were included, there was no strong evidence for mediation. For girls, obesity in adolescence has a detrimental impact on academic attainment 5 years later. Mental health, IQ and age of menarche did not mediate this relationship, suggesting that further work is required to understand the underlying mechanisms. Parents, education and public health policy makers should consider the wide reaching detrimental impact of obesity on educational outcomes in this age group.
