  1. *p < 0.05.
  2. 1 Warwick-Edinburgh Mental Well-being Scale (WEMWBS): Scores range 14 to 70. Higher scores indicate better positive mental well-being.
  3. 2A percentage estimate of work loss based on the weighted sum of the scores from the Work Limitations Questionnaire (WLQ) scales.
  4. 3The estimated percentage of time in the previous two weeks spent feeling limited in performing a specific dimension of job tasks (rated from low to high difficulty).
  5. 4Five items addressing difficulty in scheduling demands.
  6. 5Six items cover difficulty performing cognitive tasks involving the processing of sensory information and a person’s problems interacting with people on-the-job.
  7. 6Five items address decrements in the ability to meet demands for quantity, quality and timeless of completed work.
  8. 7Coefficient (95% Confidence Interval) corresponding to the physical activity logarithm.
  9. 8The coefficients of the different domains of sitting correspond to an increase of 15 min/day.
