MET-hours^* per week equivalents in walking (46)

MET-hour	Activity level as measured in walking at an average pace
1	Sitting quietly for 1 hour
< 3	< 1 hour of walking per week
3–8.9	1 to < 3 hours of walking per week
9–17.9	3 to < 6 hours of walking per week
18–26.9	6 to < 9 hours of walking per week
≥ 27	≥ 9 hours of walking per week

^*MET (metabolic equivalent task) is defined as the ratio of the metabolic rate associated with a specific activity divided by the resting metabolic rate. MET-hours is defined by the MET score multiplied by the reported hours per week engaged in that activity.
