Participation and quality of life in individuals living with chronic obstructive pulmonary disease
Bibliographic record
Abstract
Chronic obstructive pulmonary disease (COPD) is a debilitating lung disease that decreases individuals' quality of life. The purpose of this study was to examine the relationship between individuals' participation in physical activity and movement related activities (PAM; e.g., climbing up two or more flights of stairs), home related activities (AH; e.g., carrying heavy objects on a flat surface), overall burden of disease, and overall life satisfaction. Individuals living with COPD (N= 131, Mage= 68.49, SD= 8.54) responded to an online questionnaire. They reported their participation in six PAM activities and four AH activities. Participants reported their life satisfaction by responding to the Satisfaction with Life Scale, their overall disease burden with the COPD Assessment Test and the burden of breathlessness with the Medical Research Council Questionnaire on Breathlessness. Three multiple regressions were run to predict to life satisfaction, overall burden of disease and breathlessness from individuals self-reported participation in both activity categories, controlling for sex. PAM (B= .71, CI 95%: [.02, 1.40]) and AH (B= .76, CI 95%: [.26, 1.27]) significantly and positively predicted life satisfaction (R^2=.46). Both activities negatively predicted overall burden of disease (R^2=.61, BPAM= -5.54, CI 95%: [-8.35, -2.73], BAH= -3.49, CI 95%: [-5.50, -1.47]), and breathlessness (R^2= .61, BPAM= -1.16, CI 95%: [-1.58, -.74], BAH= -.30, CI 95%: [-.60, -.004]). Interventions must target functionally appropriate physical activity as enhancing participation in these activities should result in higher life satisfaction and lower burden of disease in individuals living with COPD.Acknowledgments: This research has been carried out with the support of AstraZeneca.

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.
