Taxi STEP (Social Networks, Technology, and Exercise Through Pedometers)

Testing includes weight, height, waist and blood pressure testing. In the event that the participants are unable to meet in person for health measurements, the staff will accept self-reported measurements over the phone.

The Fitbit One/Alta/Inspire wireless tracking pedometers measures steps taken, calories burned, distance traveled and sleep pattern. The Fitbit Alta/Inspire also sends reminders to move, which are notifications that remind the wearer to walk at least 250 steps each hour. If the wearer has not walked 250 steps within the hour, the device will vibrate and send an on-screen reminder 10 minutes before the hour. The reminders to move will be turned off during baseline and will be turned on at randomization for all participants.
