Relative Body Weight and Disability in Older Adults: Results From a National Survey
Bibliographic record
Abstract
OBJECTIVE: This study examined the sociodemographic, health, and economic determinants of limitations in performing instrumental activities of daily living (IADL) in Canadians 65 years and older with emphasis on the role of relative body weight. Furthermore, the study examined the relationship between these limitations and the whole range of relative body weight while controlling for the above determinants. METHOD: This research used data collected in the Canadian Community Health Survey in 2005 on Canadians 65 years and older (N = 21,255). RESULTS: The odds of experiencing IADL limitations were higher for women, the poor, and those not living with a partner. These odds also increased with advancing age and weaker physical health. Controlling for socioeconomic and health characteristics, the odds of experiencing such limitations were significantly elevated in underweight and obese individuals but not in overweight individuals. DISCUSSION: Prevention and intervention strategies targeting underweight and obese individuals should be a policy priority.

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.
