About

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.

B-MOBILE smartphone-based intervention (3-min break)

Experimental group

Description:

Participants will receive a smartphone with B-MOBILE app that automatically monitors their sedentary time and prompts them after every 30 continuous sedentary minutes to walk for at least 3 minutes. Participants who meet this goal will receive reinforcing feedback in "real time."

Treatment:

Behavioral: B-MOBILE Smartphone-Based Intervention (3-min break)

B-MOBILE Smartphone-Based Intervention (6-min break)

Experimental group

Description:

Participants will receive a smartphone with B-MOBILE app that automatically monitors their sedentary time and prompts them after every 60 continuous sedentary minutes to walk for at least 6 minutes. Participants who meet this goal will receive reinforcing feedback in "real time."

Treatment:

Behavioral: B-MOBILE Smartphone-Based Intervention (6-min break)

Control

No Intervention group
