Is There an Association between Physical Activity and Sleep in Community-Dwelling Persons with Dementia: An Exploratory Study Using Self-Reported Measures?
Bibliographic record
Abstract
Sleep disturbances are common in persons with dementia (PWD). While pharmacotherapy is widely used, non-pharmacological interventions are beginning to surface as first-line management strategies. This study sought to investigate if physical activity was associated with more favourable sleep patterns in PWD, and to compare the sleep quantity and quality between active and inactive PWD. We conducted an exploratory study to tackle these research questions. Self-reported telephone questionnaires were administered to 40 caregivers of PWD, who answered questions as proxies on behalf of their care recipient. Just over half (55%) of our participants met the criteria for being active. Walking was the most popular form of physical activity for both active and inactive PWD. Active PWD also preferred exercise classes and gardening, whereas inactive PWD favoured chair exercises. Compared to their inactive counterparts, active PWD were more likely to experience appropriate sleep quantity (p = 0.00). The active group also reported significantly better overall sleep quality (p = 0.003). Together, our findings suggest that physical activity may be associated with improved sleep in PWD. Future studies are warranted to investigate whether physical activity can be promoted as a safe and effective means to improve quality-of-life in this population.

How this classification was reachedexpand
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.
