Timeline
Interventions
The program includes (1) use of a free commercially available smartphone application program for 12 months, (2) a wearable Fitbit Charge device that will be provided by the study to monitor active minutes, and (3) one 45-minute behavioral counseling session focused on healthy eating and exercise and (4) personalized text messaging for 6 months by a health coach. The health coach will not send feedback during months 6-12. The intervention will be fully self-directed in these months, as there will be no contact between the 6 months visit and 12-month visit.
