  2. a Overall activity included recreational, occupational, transportation, child and adult care-giving, indoor household, and outdoor household activity.
  3. b Hours per week (h/wk); total h/wk is a sum of fairly light, somewhat hard, hard, or very hard activity.
  4. c MET hours per week (MET h/wk); total MET h/wk is the sum of total h/wk multiplied by established MET value19,20 of the reported type of physical activity.
