Outcomes

Primary Outcomes

Daily Step Count

Change in steps/day from week 1 to week 12.

Time frame: Change from week 1 to week 12

Secondary Outcomes

Program Compliance

Compliance with the physical activity prescription, means meeting or exceeding the step goal for that day. Participants' compliance was assessed by totaling the number of days they met their step goal and dividing it by the total number of days of the intervention. Thus, providing investigators the percentage of days that each participant complied with their physical activity prescription.

Time frame: Change from week 1 to week 12
