Disability and Frailty Among Elderly Canadians: A Comparison of Six Surveys
Bibliographic record
Abstract
The first wave of the Canadian Study of Health and Aging (CSHA) constituted a large health survey of a representative sample of elderly Canadians. Other Canadian surveys from the same era provided equivalent figures, and the present report compares the results of 6 surveys on a variety of health indicators. Agreement was close on self-reported chronic health conditions, adequate for several indicators of functional limitation, but was lower for overall self-ratings of the impact of health problems on day-to-day life. Using the CSHA data to compare alternative operational definitions of frailty, a definition based on ADL limitations appeared to offer an underestimate; addition of IADL questions or cognitive limitations provided figures that appeared more plausible. Survey estimates of chronic health conditions appear consistent, as are estimates of certain ADL disabilities. Care must be taken with interpreting more subjective reports, while prevalence of frailty varies considerably according to the definition used.

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.
