Exercise and BMI in Overweight and Obese Children and Adolescents: A Systematic Review and Trial Sequential Meta-Analysis.

ABSTRACT:

Objective

Determine the effects of exercise on body mass index (BMI in kg · m(-2)) among overweight and obese children and adolescents.

Methods

Trial sequential meta-analysis of randomized controlled exercise intervention trials ≥ 4 weeks and published up to November 11, 2014.

Results

Of the 5,436 citations screened, 20 studies representing 971 boys and girls were included. Average length, frequency, and duration of training were 13 weeks, 3 times per week, for 46 minutes per session. Overall, random-effects models showed that exercise decreased BMI by 3.6% (mean: -1.08; 95% CI: -0.52 to -1.64; Q = 231.4; p < 0.001; I (2) = 90.9%; 95% CI: 87.6% to 93.4%; D (2) = 91.5%). Trial sequential meta-analysis showed that changes in BMI crossed the monitoring boundary for a typ
