Do overweight and obese youth take longer to recover from injury?
Bibliographic record
Abstract
The objective of the study was to examine the effects of overweight and obesity on times to recovery among Canadian youth who have suffered one or more types of injury. The data source was the 2002 Canadian Health Behaviour in School-Aged Children (HBSC) survey. The study population included 7266 youth in grades 6 through 10 sampled from all Canadian provinces and territories. Of these, 2831 students reported an injury event and were included in the analysis. Kaplan-Meier curves and hazard ratios (HR) were used to profile survival functions and estimate relative hazards for non-recovery from injury events among normal weight, overweight and obese youth. Youth who were obese and suffered a combined injury (broken bone and strain/sprain) took longer to recover (HR: 1.81, 95% CI 0.99-3.32) compared to normal weight youth. HR for injury recovery in obese youth were not significantly elevated for broken bones (1.15, 95% CI 0.61-2.19) and sprain/strains (1.17, 95% CI 0.73-1.85) in isolation. Obesity was associated with times for injury recovery among injured youth. If these findings are confirmed in other settings, clinicians providing an injury recovery prognosis may need to take into account BMI status and allow for extra recovery time for patients in this age range.

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.
