Dietary Intervention Examining Tracking With Mobile Devices (DIETMobile)

April 16, 2019 updated by: Brie Turner-McGrievy, University of South Carolina

The Dietary Intervention Examining Tracking With Mobile Devices Study

The purpose of the study is to test the effectiveness of two different weight loss interventions. Both of these interventions will provide weight loss information through twice weekly audio podcasts. In addition to the podcasts, participants will be asked to track their diet using either a wearable device on their wrist or through an app on their smartphone.

Detailed Description

This study will last approximately 6 months. Participants will attend one 1-hour orientation meeting at the beginning of the study and a 2-hour baseline assessment and training meeting. Additional assessments will be conducted at 3 months and 6 months. Weekly questionnaires will be administered. Everyone in the study will be asked to listen to 2 podcasts per week. Each of the podcasts will take about 15 - 20 minutes to listen to and so participants should expect to spend 30 - 40 minutes each week listening to podcasts. Participants will also be randomized to either track diet with an app on their smartphone or using a device they wear on their wrist. Each week, participants will be sent an email as a reminder on how to use their diet tracking device. They will also be encouraged to monitor their exercise and body weight.
