SD, standard deviation; Min, minimum; Max, maximum; SD-PA, step-defined physical activity.
^a Percentage of values which met at least 7,500 or 10,000 steps/day.
^b Change between intervention weeks 1 and 2 and remaining intervention weeks (3–27).
Positive change indicates an increase during intervention.
