Literature dealing with the impact of organized sports on children's weight has been marked by a lack of consensus. A major weakness characterizing most of this research is a lack of proper measurement methods. This paper seeks to fill an important knowledge gap through careful application of econometric methods.
Estimations are carried out using data on 1,400 children attending 6th grade in 2008 in the municipality of Aalborg, Denmark. We use standard ordinary least squares (OLS) and class fixed effects to explore the effect of sports participation on body mass index (BMI) as well as underweight, overweight and obesity.
Results indicate that participation in organized sports reduced BMI by 2.1%. Likewise it reduced the likelihood of being overweight by 8.2 percentage points and obese by 3.1 percentage points.
It is the unique dataset combined with econometric methods that distinguishes our contribution from that of others in the field, thereby offering new insight. Results using statistically sound methods suggest that participation in organized sports has a beneficial effect on children's weight.
关于组织体育活动对儿童体重影响的文献一直存在分歧。这方面的研究大多存在一个主要弱点，即缺乏适当的衡量方法。本文旨在通过谨慎应用计量经济学方法来填补这一重要知识空白。
本研究使用了 2008 年丹麦奥尔堡市 6 年级 1400 名儿童的数据进行估计。我们使用标准普通最小二乘法（OLS）和班级固定效应来探讨参与体育活动对体重指数（BMI）以及体重过轻、超重和肥胖的影响。
结果表明，参加有组织的体育活动可使 BMI 降低 2.1%。同样，它还降低了超重的可能性 8.2 个百分点，并降低了肥胖的可能性 3.1 个百分点。
正是独特的数据和计量经济学方法使我们的研究有别于该领域的其他研究，从而提供了新的见解。使用统计上可靠的方法得出的结果表明，参加有组织的体育活动对儿童的体重有有益的影响。
