Does physical activity really improve anxiety and depression in overweight or obese children and adolescents? A systematic review and meta-analysis.
Synthesis in BMC psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo evaluate the effects of physical activity (PA) on anxiety, depression, self-esteem, and self-worth in overweight/obese children and adolescents.
methodsA systematic search of six databases was conducted from inception to March 1, 2025. Randomized controlled trials (RCTs) examining the effects of PA on mental health outcomes in children and adolescents (aged 5–19 years) with overweight/obesity were included.
resultsNineteen RCTs (1,795 participants) were analyzed. PA was associated with improvements in anxiety (SMD = -0.98, 95% CI -1.90 to -0.05, P = 0.04), depression (SMD = -0.15, 95% CI -0.25 to -0.05, P = 0.005), self-esteem (SMD = 0.19, 95% CI 0.03 to 0.35, P = 0.02), and self-worth (SMD = 0.34, 95% CI 0.19 to 0.49, P = 0.0002). However, the evidence for anxiety was of low certainty, and the improvements in depression and self-esteem were modest. The effects were also modulated by age, obesity level, and race.
conclusionPA was associated with small to modest improvements in mental health outcomes among young people. While PA may reduce anxiety, the evidence is uncertain, and the observed effects on depression and self-esteem appear small and of modest clinical relevance, supporting PA as an adjunctive mental health strategy.
