Study summary

Greater time spent in sedentary behaviors, independent of physical activity level, can increase risk of morbidity and mortality. Objective assessments indicate that bariatric surgery patients spend large amounts of time in sedentary behaviors. The present study is the first to test whether a mobile health (mHealth) approach that employs widely adopted smartphone technology to monitor and modify sedentary behaviors as they occur is a feasible and acceptable method of reducing sedentary time in these patients and other obese populations.

Interventions

  • BehavioralBehavioral intervention to reduce sedentary time delivered via mobile smartphone

    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.
