Socioeconomic Status and Sport Participation at Different Developmental Stages During Childhood and Youth: Multivariate Analyses Using Canadian National Survey Data
Bibliographic record
Abstract
This study examines the relationship between socioeconomic status (SES) and sport and physical activity involvement at different stages of childhood and adolescence in Canada. From the previous literature on SES and health-related behavior, there was reason to test competing hypotheses on the direction of the predicted relationship. The data employed in our analyses came from Cycle 3 of the National Longitudinal Survey of Children and Youth—1998–1999. Results, after controls, showed that SES was a significant predictor of sport involvement among 6–9 year-olds, but not for 10–15 year-olds. In the younger group, the higher the family SES the more frequent was the involvement. The effects of SES were much stronger for organized sport involvement than for participation in an informal context. The discussion bears on the implications of these findings for later adult physical activity and sport involvement and their ramifications for sport and exercise promotion policy.

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.
