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-2 . 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-2 were not observed as a result of aerobic exercise in children and adolescents with overweight and obesity.
