Reducing Sedentary Time in Obese Adults

The overall goals of the intervention are to decrease overall sedentary time and to increase the number of breaks in sedentary time. The intervention approach combines an advanced smartphone device with an on-board accelerometer and a sophisticated smartphone application to: 1) monitor participants sedentary behavior in real time in their natural environment; and 2) use monitored data to deliver immediate, individually-tailored, goal-driven prompts and feedback to encourage substitute of sedentary behaviors with physical activity.
