A137: Meeting 24-Hour Movement Guidelines and Affect Balance in Children and Adolescents: A Multiple-Mediation Model Analysis
Bibliographic record
Abstract
Background/Purpose: The Canadian 24-hour movement guidelines recommend an adequate level of physical activity, a limited amount of recreational screen time use, and sufficient sleep duration for children and adolescents. Affect balance is essential for children and adolescents’ physical health, psychological health, academic achievement and long-term development. Daily movement behaviors have been shown to influence affect balance with limited research. Whether and how meeting 24-hour movement guidelines relates to affect balance remains unclear. The aim of this study was to examine the relationship between meeting 24-hour movement guidelines and affect balance, and to explore the mediating effects of executive function and cognitive reappraisal. Method: A total of 530 Chinese children and adolescents with a mean age of 12.95 years (49.81% males) participated in this study. The three components of 24-hour movement behaviors (physical activity, recreational screen time, and sleep) were measured and coded respectively according to guideline recommendations. Meeting 24-hour movement guidelines was handled in terms of continuous variable (0 vs. 1 vs. 2 vs. 3). Participants also completed the Positive and Negative Affect Scale, the Adolescent Executive Function Scale, and the Emotional Regulation Questionnaire. SPSS 26.0 was used for descriptive statistics, univariate analysis of variance and correlation analysis of relevant data. The Hayes’ PROCESS 3.3 macro was used to examine direct and indirect effects between variables. Results: Meeting 24-hour movement guidelines showed a significant and positive association with affect balance (β = 1.413, p = 0.036). Executive function played a mediating effect between meeting 24-hour movement guidelines and affect balance (effect = 1.275, 95% CI: 0.486−2.083). Furthermore, executive function and cognitive reappraisal played sequential mediating effects between meeting 24-hour movement guidelines and affect balance (effect = 0.158, 95% CI: 0.052−0.299). The total indirect effects of execution function and cognitive reappraisal accounted for 55.84% of the total. Conclusion/Discussion: Meeting 24-hour movement guidelines promoted affect balance in children and adolescents by influencing executive function and through the sequential mediating effects of executive function and cognitive reappraisal. This study moved beyond prior research and provided a more comprehensive understanding of whether and how meeting 24-hour movement guidelines relates to affect balance. It also provided some enlightenment for the daily behavior management of children and adolescents. Measures should be taken to improve moderate to vigorous physical activity, ensure adequate sleep, and reduce recreational screen time to maintain children and adolescents’ affect balance.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
