Can A Smartphone App Encourage You To Be More Active? Miriam Hospital Researchers Want To Know


A sedentary lifestyle is a risk factor for many illnesses and serious health conditions, including diabetes and heart disease, even if you exercise regularly. Now researchers at The Miriam Hospital’s Weight Control and Diabetes Research Center are launching a new study, known as B-MOBILE, to see if a smartphone app can help encourage individuals to reduce sedentary behaviors and improve their overall health.

Participants will attend five office visits at the Weight Control and Diabetes Research Center over a four-week period. After completing a weeklong baseline assessment of sedentary behavior, participants will be asked to complete three different goal conditions that vary the duration of prescribed breaks or interruptions in sedentary time.

To help participants achieve the different goals, a smartphone and accompanying “app” will be provided that delivers real-time prompts and feedback to get up and move after extended periods of sitting and lying down during waking hours. Participants will be asked to follow each of the goal conditions for seven days.

To be initially eligible for the study, participants must be between the ages of 21 and 65 and be obese (i.e. body mass index, or BMI, of 30 or greater). All B-MOBILE participants will receive education about sedentary behaviors and related health risks and will be financially compensated for their time. Smartphones will be provided to participants free of charge for the duration of the study.
