BACKGROUND
Exercise has been recommended as an important intervention for reducing adiposity in children and adolescents with overweight and obesity.
OBJECTIVE
Determine whether inter-individual differences exist in relation to exercise-induced changes in adiposity among children and adolescents with overweight and obesity.
METHODS
Meta-analysis of randomized controlled aerobic exercise trials and body mass index (BMI) in kg · m . Change outcome standard deviations were pooled using the inverse-variance heterogeneity model.
RESULTS
Twenty-eight studies (1185 participants) were included. Inter-individual differences in BMI were -0.1 (95% compatibility interval, -0.7 to 0.7). The 95% prediction interval for inter-individual responses in a future study was -2.9 to 2.9. The probability of a clinically meaningful difference in variability was 29% (possibly clinically important) in favour of controls vs exercisers.
CONCLUSIONS
Inter-individual differences for BMI in kg · m were not observed as a result of aerobic exercise in children and adolescents with overweight and obesity.
背景
运动已被推荐为减少超重和肥胖儿童和青少年体脂的重要干预措施。
目的
确定超重和肥胖儿童和青少年中，个体间是否存在与运动引起的体脂变化相关的差异。
方法
对随机对照有氧运动试验和体重指数（BMI）的荟萃分析，kg·m。使用逆方差异质性模型对变化结果的标准差进行汇总。
结果
纳入了 28 项研究（1185 名参与者）。BMI 的个体间差异为-0.1（95%可信区间，-0.7 至 0.7）。未来研究中个体反应的 95%预测区间为-2.9 至 2.9。在控制组与运动组之间，可变性的临床意义差异的可能性为 29%（可能具有临床意义）。
结论
在超重和肥胖的儿童和青少年中，有氧运动对 BMI 的个体间差异没有影响。
