Overview

Systematic review finds physical activity may improve mental well-being and health outcomes in adolescents with obesity, highlighting the need for higher-certainty evidence.

Key Points

To evaluate the benefits and harms of physical activity interventions lasting at least 12 weeks for managing obesity in adolescents aged 10 to 19 years.
Systematic search across CENTRAL, MEDLINE, Embase, and trial registries from 2012 to December 2025 without language restrictions.
Included 30 randomized controlled trials (N=1508) across 15 countries evaluating physical activity versus no-intervention or active controls in adolescents aged 10 to 17 years.
Assessed risk of bias using the Cochrane RoB 1 tool and synthesized outcomes using random-effects meta-analyses or synthesis without meta-analysis (SWiM), graded by GRADE.
Physical activity versus no intervention improved mental well-being measures in one trial (N=56), including self-efficacy (MD 0.58, 95% CI 0.21 to 0.95) and self-esteem (MD 0.47, 95% CI 0.18 to 0.76), but self-perception showed wide uncertainty (MD 0.22, 95% CI -0.10 to 0.54).
Evidence for physical activity levels, blood pressure, adiposity, insulin, fasting glucose, and lipid biomarkers was rated low or very low certainty, and all 30 included studies were at high risk of bias.
Comparative trials assessing distinct exercise modalities (such as high-intensity interval training versus moderate-intensity continuous training) provided very low-certainty evidence, leaving relative effectiveness uncertain.
