Relationships of leisure activities with physical and cognitive functions among Chinese older adults: A prospective community-based cohort study
Bibliographic record
Abstract
OBJECTIVES: Based on a prospective design, this study aimed to investigate the relationships of leisure activities with physical and cognitive functions among Chinese older adults. METHODS: The respondents aged 65 years or more were selected from the 2014-2018 of the Chinese Longitudinal Healthy Longevity Survey. Physical function measurement indicators were reflected by activities of daily living (ADL), instrumental activities of daily living (IADL), and physical performance (PP), while cognitive function was assessed by Mini-Mental State Examination. Fine-Gray competing risk regression models were used to analyze the data. RESULTS: Using the figures for 2014 as a baseline for the study, we included 6047, 6216, 5951, and 5916 respondents in the ADL, IADL, PP, and cognitive function analyses, respectively. The prospective results showed that keeping domestic animals or pets was related to a lower risk of ADL disability of respondents after adjustment (SHR: 0.619, 95% CI: 0.486, 0.788). Similarly, taking part in social activities (SHR: 0.781, 95%CI: 0.658, 0.929) and reading books or newspapers (SHR: 0.793, 95% CI: 0.656, 0.958) were associated with a lower risk of IADL disability. Playing cards or mahjong was correlated with a lower risk of cognitive impairment (SHR: 0.669, 95% CI: 0.507, 0.882), while keeping domestic animals or pets was related to a higher risk of cognitive impairment (SHR: 1.279, 95% CI: 1.047, 1.562). CONCLUSION: Participation in leisure activities moderately may decrease the risk of a decline in physical and cognitive functions among Chinese older adults.

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.
