Physical inactivity in Canadian adolescents and their associations with chronic disease and social economics
Bibliographic record
Abstract
UNLABELLED: Physical activity is an important determinant of population health. In this paper, we examine levels of physical activity among Canadian adolescents in relation to socioeconomic status. METHODS: Data from the Canadian Community Health Survey, Cycle 2.1, conducted in 2003, were used to evaluate the association between socioeconomic status and physical activity. This survey included 9,294 males between 12 and 20 years of age, and 9,147 females in the same age range. RESULTS: Among adolescents aged 12 to 20 years, 55.9% of males and 39.2% of females were physically active. The proportion of subjects in the active category tended to decrease with age in both males and females. Adolescents from low income families were more physically inactive (odds ratio=1.30, 95% confidence interval=1.29-1.32) than those from high income families. CONCLUSION: Physical inactivity in adolescence represents an important population health issue in Canada. Physical activity levels tended to be higher among males, younger people, and those with higher socioeconomic status. Multi-sectoral policies and initiatives are needed to create environments that promote physical activity among Canadian youth.

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.
