Health associations with meeting the Canadian 24-hour movement guidelines for adults and older adults
Bibliographic record
Abstract
Background: The Canadian 24-Hour Movement Guidelines for Adults aged 18-64 years and Adults aged 65 years or older (24hrMG) provide evidence-based recommendations for moderate-to-vigorous physical activity (MVPA), sedentary behaviour (SB) and sleep. Purpose: To examine whether meeting the overall 24hrMG, and different combinations of guideline recommendations, were associated with health indicators in a representative sample of Canadian adults. Methods: Participants were 8,297 adults aged 18-79 years from the Canadian Health Measures Survey. They were classified as meeting or not meeting each of the 24hrMG recommendations: MVPA (≥150 minutes/week), SB (≤9 hours/day of sedentary time including ≤3 hours/day of recreational screen time), and sleep duration (adults 18-64 years: 7-9 hours/day, adults aged ≥65 years: 7-8 hours/day). A combination of self-reported and device-based measures were used. Indicators of adiposity (n=2), aerobic fitness (n=1), and cardiometabolic health (n=7) were measured. Results: A total of 19.1% of the sample met none, 43.9% met one, 29.8% met two, and 7.1% met all three recommendations. Compared to meeting no recommendations, meeting one, two and all three recommendations was associated with better health for one, six and seven health indicators, respectively (p

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.
