Contribution of Self-Reported Health Ratings to Predicting Frailty, Institutionalization, and Death Over a 5-Year Period
Bibliographic record
Abstract
Cross-sectional data from Phase 1 of the Canadian Study of Health and Aging was used to examine the relationship between two self-report health measures: "How would you say your health is these days?"(HEALTH) and "How much do your health troubles stand in the way of your doing the things you want to do?"(TROUBLE). The contribution of these measures to predictive models for institutionalization and mortality is examined, using linked data from Phases 1 and 2. Their relationship to a proposed frailty measure is also examined. At CSHA-1, a majority of respondents perceived that they were in good health and did not feel that their health problems interfered with their preferred activities. At all frailty levels, a majority of both males and females rated their health as "very good" or "pretty good." As frailty increased, health problems increasingly interfered with normal activities. Logistic regression of the longitudinal data indicated that, despite their correlation, HEALTH and TROUBLE cannot act as proxies for each other. They appear to predict independently; adding one to the other significantly improved prediction of institutionalization and mortality.

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.
