Inter-individual differences in body mass index were not observed as a result of aerobic exercise in children and adolescents with overweight and obesity

摘要

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.
