Participant Flow

Recruitment was done by word of mouth and flyer, as only 8 subjects were required. Researchers connected with community/church leaders in the neighborhood to plan the recruitment of subjects for the study.

In total, 13 people were assessed. Four did not meet inclusion criteria, and 1 declined. Eight were enrolled. Subjects were given anonymous identifiers, subject IDs numbered 1-8. Randomization was completed as one-big-block-of-8. Four were chosen to be in the control group; the others received the intervention.

Measure
Required Supervised Walking
Device: Fitbit Flexes Required supervised walking: The intervention will include meeting at an agreed upon community center location and time convenient for both the participant and the researcher. During these meetings, the participants will engage in indoor walking under the supervision of the researcher. This is to ensure accurate walking distance recording and also to monitor the participants for any potential adverse events. The participants will have the option of walking as long or short as they please, so long that it is less than 20 miles per week. This is to protect the participants from exhaustion or overexertion. Overall activity of this group will be recorded using Fitbit Flexes, worn at all time for the duration of the study. Fitbit Flex
Non-required Supervised Walking
Device: Fitbit Flexes Non-required supervised walking: The intervention will include meeting at an agreed upon community center location and time convenient for both the participant and the researcher. During these meetings, the participants will engage in indoor walking under the supervision of the researcher. This is to ensure accurate walking distance recording and also to monitor the participants for any potential adverse events.
