OBJECTIVELY MEASURED PHYSICAL ACTIVITY ACROSS OCCUPATIONS BASED ON THE NHANES
Bibliographic record
Abstract
Occupational activity may contribute significantly to daily physical activity (PA). The 2003–2006 National Health and Nutrition Examination Survey (NHANES) surveillance cycles provide an opportunity to evaluate the amount of daily PA in occupational categories. Population estimates of accelerometer-derived PA variables were compared for men and women (n=1112 and n=1501) working the 40 and 22 occupational categories in the 2003–2004 and 2005–2006 NHANES, and used to classify the occupational categories: high, intermediate, and low activity groupings based on total daily PA. There was a strong association between occupational category and total daily PA. Labor jobs were generally high active, while office jobs were generally low active. Men had more moderate-to-vigorous activity than women in all activity groupings. Presenting objectively measured PA from a large representative sample with a variety of occupations provides previously unquantifiable information about the daily PA levels of people employed in different occupational categories.

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.
