The effect of physical-activity intervention on children’s health-related quality of life
Bibliographic record
Abstract
Aims: We investigated the effect of a school-based physical-activity intervention on children’s health-related quality of life (HRQoL) and the potential influence of moderate to vigorous physical activity (MVPA). Methods: A randomised, controlled trial (Active School) involving fifth-grade children was conducted during the 2014/15 school year. The sample included 435 children (10–11 years old) at five intervention schools and four control schools. The weekly interventions concerned two 45 min of physically active lessons, five 10 min of physically active breaks and five 10 min of physically active homework. The children’s HRQoL was measured using KIDSCREEN-27 and a self-report questionnaire, while physical activity was measured using accelerometers. Results: The results of multilevel analysis showed a significant effect on psychological wellbeing ( p = 0.005), social support and peers ( p = 0.005) and school environment ( p = 0.013). No gender differences were observed. Children’s MVPA did not influence their KIDSCREEN-27 score. Conclusions: The school-based physical-activity intervention (Active School) shows positive effects on children’s self-reported psychological wellbeing, social support and peers, and school environment.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
