An examination of how physical activity and sedentary behaviour in older adults in Assisted Living associate with physical, cognitive and psychosocial function
Bibliographic record
Abstract
Physical activity and sedentary behaviour are important markers of health and quality of life, and predictors of functional decline.However, the factors that influence movement patterns in older adults, especially for those residing in the growing assisted living (AL) setting, are poorly understood.I acquired measures from 114 AL tenants of movement patterns from waist-mounted accelerometers worn for at least 3 days.On average, participants spent 86% of their waking hours in sedentary behaviour and 13.84% in light physical activity.The time spent sedentary was higher in males than females, and correlated with scores on the Timed-Up-and-Go and Modified Fall Efficacy Scale, but not with the Montreal Cognitive Assessment or Geriatric Depression Scale.These results indicate that both physical function and psychological factors influence sedentary behaviour in AL tenants.Future research should examine whether interventions targeted at intrinsic or environmental factors decrease sedentary behaviours.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
