需要制定战略，防治日益严重的儿童肥胖问题。学校环境已经被指出是潜在的有效预防环境。摘要本研究旨在探讨每周4节额外的小学体育课程对8-13岁儿童身体成分和体重状况的影响。10所公立学校、6所干预学校和4所对照学校的二至四年级儿童（n = 632）参加了为期2个学年的纵向研究。主要指标：身体质量指数（BMI）和总体脂率（TBF%）由双能X线吸收仪（DXA）得出。其次：超重/肥胖（OW/OB）和肥胖的调节作用基于性别的TBF%截断值。干预对BMI和TBF% （BMI: β -0.14, 95% CI: -0.33; 0.04, TBF%: β -0.08, 95% CI:-0.65;0.49）的影响不显著。然而，我们发现基于BMI的干预对OW/OB患病率有显著的有益影响（OR 0.29, 95% CI: 0.11;0.72）。基于TBF%截断值的肥胖干预效果具有显著的临界意义(OR 0.64, 95% CI:0。39;1.05)。每周在学校额外上四节体育课可以显著提高小学生OW/OB患病率。平均BMI和TBF%在干预学校有所改善，但与对照组差异不显著。干预对基线时肥胖或肥胖的儿童有更大的影响。
Strategies for combating increasing childhood obesity is called for. School settings have been pointed out as potentially effective settings for prevention. The objective of this paper was to evaluate the effect of four additional Physical Education (PE) lessons/week in primary schools on body composition and weight status in children aged 8–13. Children attending 2nd to 4th grade (n = 632) in 10 public schools, 6 intervention and 4 control schools, participated in this longitudinal study during 2 school years. Outcome measures: Primary: Body Mass Index (BMI) and Total Body Fat percentage (TBF%) derived from Dual Energy X ray Absorptiometry (DXA). Secondary: the moderating effect of overweight/obesity (OW/OB) and adiposity based on TBF% cut offs for gender. Intervention effect on BMI and TBF% (BMI: β -0.14, 95% CI: -0.33; 0.04, TBF%: β -0.08, 95% CI:-0.65;0.49) was shown insignificant. However, we found significant beneficial intervention effect on prevalence of OW/OB based on BMI (OR 0.29, 95% CI: 0.11;0.72). The intervention effect on adiposity based on TBF% cut offs was borderline significant (OR 0.64, 95% CI:0. 39; 1.05). Four additional PE lessons/week at school can significantly improve the prevalence of OW/OB in primary schoolchildren. Mean BMI and TBF% improved in intervention schools, but the difference with controls was not significant. The intervention had a larger effect in children who were OW/OB or adipose at baseline.
