Abstract

fetched live from OpenAlex

BACKGROUND: Monitoring and improving physical activity levels is essential for promoting healthy aging. The objective of this study was to create age-specific normative values for the Physical Activity Scale for the Elderly (PASE) among community-dwelling women and men aged 45-85 years old. METHODS: 36,701 participants (47% female) aged 45-85 years old, free of any mobility limitation or activities of daily living disability from the Canadian Longitudinal Study on Aging (CLSA) were included. Best fitting models were identified using Generalized Akaike Information Criteria values and cross-validation. Seasonal differences for males and females were also explored. RESULTS: Separate models for males and females are presented, providing a range of percentile values (5-95%) in charts and tables. Total PASE scores were highest in 45-year-olds and decreased with age. Seasonal differences were not substantial or consistent at the population level. CONCLUSIONS: The age- and sex- specific normative values provided can improve the interpretability of PASE scores among middle-aged and older adults. In addition to PA guideline cut-offs, normative values provide further information for monitoring physical activity by allowing for more personalized observations that account for healthy variation.

Not 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.
