Functional health status and satisfaction with health in a population reporting a participation or activity limitation: Focus on COPD
Bibliographic record
Abstract
Background: Symptoms associated with COPD can result in participation and activity limitations as well as reduced quality of life. Objective: To examine the impact of COPD on functional health status (FHS) and satisfaction with health (SWH) in persons with a participation or activity limitation among a national sample of Canadians. Methods: This survey used data from the 2006 Participation and Activity Limitation Survey (PALS), a complex population survey of Canadians reporting a disability on the census. COPD was present if there was a self-report of COPD, emphysema, or bronchitis as the cause of disability. FHS was assessed using the Health Utility Index (HUI-3) and categorized as high, moderate, or severe. SWH was categorized as high, moderate, or low. Analyses were weighted to the population and bootstrapping used to estimate variances. Results: The sample represents 5,185,980 adults with participation or activity limitation. Subjects without missing data (55%) for the variables of interest were included. COPD was reported as the reason for disability in 1.4% of the population. Among those reporting COPD, 44% reported moderate and 49% reported low SWH. FHS was moderately impaired for 31% and severely impaired for 46%. After adjustment, COPD was significantly associated with a lower SWH (p Conclusions: While FHS was similar to the overall population with a disability, persons with COPD had a markedly lower SWH, suggesting the need to focus on quality of life enhancement strategies.

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.
