Abstract
This umbrella review analyzed the effectiveness of school-based interventions, applying body weight or behavioral outcomes. Twelve systematic reviews and five meta-analyses (examining 196 trials) were included. Results indicated that the effectiveness was usually referred to body weight or BMI change, with 1/3 of trials (per review) indicating significant changes in BMI or obesity prevalence. Meta-analyses yielded mixed effects (three showed significant changes in weight, BMI, or obesity). Interventions were more effective if they aimed at a reduction of sedentary behaviors, incorporated moderate-to-vigorous physical activity, and parental involvement. The inclusion of a nutrition component moderated the long-term effects of interventions. More efficient interventions lasted at least 3 months, did not aim solely at environmental changes, and were implemented in general population. Female and younger participants may benefit more from the interventions. The role of psychological theories and behavioral or cognitive mediators was rarely investigated.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
