Contribution of disability to self-perceived health in community dwelling seniors
Bibliographic record
Abstract
Self-reported health (SRH) is an important part of the multidimensional construct health related quality of life (HRQL). SRH in the elderly is particularly important, as their absolute and relative numbers are increasing worldwide. In elderly patients, self-reported health is strongly associated with the adverse health outcomes of aging. Knowledge about factors affecting SRH would be informative for ongoing health management of elderly persons. The literature is consistent that aspects of function are important contributors to SRH, making 'function' an important target for prevention and rehabilitation in the elderly. The main objective of this study was to identify, for a community dwelling older population, the extent to which indicators of functional status contribute to general health perception over and above known personal and health related contributors, and to ascertain whether the profile of contributors remains stable over one year. A longitudinal study of a population-based sample of 215 community-dwelling individuals 65 years of age and older, recruited randomly in 1995 from Montreal area, was carried out. Ordinal regression was applied at study entry and twelve months later. The main outcome - self- reported health was measured with the General Health Perception Scale from the Medical Outcomes Study 36-item Short Form (SF-36). Half of the sample was stable (43%) and an equal proportion of people improved or deteriorated. Fatigue was a factor predicting both SRH at study entry and change over time; social engagement was a factor predicting change as was physical function. This information could indicate that worsening fatigue, loss of social engagement and deteriorating physical function could be early warning signs of deteriorating health and these may appear before the effects are detected using standard medical investigations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
