Supplementary information files for "The effectiveness of combined dietary and physical ac

Supplementary files for a systematic review and meta-analysis examining the effectiveness of combined diet and physical activity interventions on adolescent behaviors and adiposity outcomes. The dataset includes 36 studies, with 79% conducted in high-income countries and 78% delivered in school settings. The files were authored by Natalie Pearson and last updated in April 2026.

Use Cases

• Replicate meta-analysis results for BMI z-score and body fat percentage changes based on the reported standardized mean differences.
• Analyze the geographic and setting distribution of included studies based on the high-income country and school-setting focus.
• Investigate the relationship between intervention characteristics and reported behavioral outcomes based on the narrative synthesis of behaviors.

Strengths

• Includes data from 36 controlled intervention studies.
• Reports specific meta-analysis results, including a significant reduction in BMI z-score (SMD -0.62) and body fat percentage (SMD -1.32).
• Clearly documents the geographic focus, with 79% of studies from high-income countries.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The evidence base is largely from high-income countries, which may limit generalizability.
