Body Mass Index and the Odds of Acute Injury in Children
Bibliographic record
Abstract
OBJECTIVE: The objectives of this study were to determine (1) the association between body mass index (BMI) and acute injury and (2) the association between BMI and bone fracture in children. METHODS: Children 5 to 17 years old were recruited in the emergency department at the British Columbia Children's Hospital. Cases included children treated for an injury, and control subjects were children without an injury in the past 12 months. Participants were administered a questionnaire to derive average activity level and demographic data. Weight and height measurements were taken to calculate BMI. Bivariate and multivariate logistic regressions were used to estimate the odds of injury occurrence by BMI category and the impact of covariates. RESULTS: Logistical regression, after adjusting for age, sex, activity level, and income level, did not reveal an increased association between BMI and acute injury in overweight odds ratio (OR) = 0.90 (0.48-1.70) and obese OR = 1.18 (0.60-2.33) children. Secondary outcome analyses failed to show an increased association between BMI and fracture in overweight OR = 0.44 (0.12, 1.66) and obese OR = 1.02 (0.31, 3.32) children. CONCLUSIONS: This study did not find increasing BMI to be associated with increased acute injury or bone fracture in children.

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.
