Physical activity scoring.

	Physical Activity Scoring
Walking	MET-min/week = 3.3 × min of activity/day × days per week
Moderate PA	MET-min/week = 4.0 × min of activity/day × days per week
Vigorous PA	MET-min/week = 8.0 × min of activity/day × days per week
Total amount of PA	Walking MET-min/week + Moderate PA MET-min/week + Vigorous PA MET-min/week

PA: physical activity; MET: metabolic equivalent task.
