  1. SD: Standard Deviation.
  2. 1High category: achieving a minimum total physical activity of at least 3,000 MET-minutes/weeks.
  3. Moderate category: achieving a minimum total physical activity of at least 600 MET-minutes/weeks.
  4. Low category: Individuals who do not meet criteria for categories 2 or 3.
  5. 2Warwick-Edinburgh Mental Well-being Scale (WEMWBS): The minimum score is 14 and the maximum is 70. Higher scores indicate better positive mental well-being.
  6. 3Each scale score indicates the percentage of time in the previous two weeks when the respondent was limited in performing a specific dimension of job tasks (from low to high rate of difficulty in performing job demands). The minimum score is 0 (limited none of the time) to 100 (limited all of the time).
  7. 4Five items addressing difficulty in scheduling demands.
  8. 5 Six items covering difficulty performing cognitive tasks at work.
  9. 6Five items addressing decrements in the ability to meet demands for quantity, quality and timeless of completed work.
  10. 7A percentage estimate of work loss based on the weighted sum of the scores from the WLQ scales.
