Conditions
Brief summary
The purpose of this study is to examine whether a behavioral lifestyle intervention using mobile smart phone technology for self-monitoring can lead to greater improvements in diabetes outcomes.
Detailed description
The investigators will conduct a pilot randomized controlled clinical trial to examine the feasibility and preliminary efficacy of a behavioral lifestyle intervention on weight, glycemic control, and vascular inflammatory marker outcomes. A total of 26 overweight or obese patients with type 2 diabetes will be recruited from an underserved minority community health center in Houston, TX. They were randomly assigned into one of the three groups: 1) Behavior intervention with smart phone based self-monitoring, 2) Behavior intervention with paper diary based self-monitoring, and 3) Usual care group. Both Mobile and Paper groups received a total of 11 group sessions and 1 individual session in a 6-month intervention. Mobile group received an android-based smart phone with two applications loaded to help them record their diet, physical activity, weight, and blood glucose, while the paper group is using paper diaries for these recordings.
Interventions
BEHAVIORALBehavior intervention with smart phone based self-monitoring
Use two smartphone applications for self-monitoring of diet, physical activity, weight, and blood glucose (connected via a blue-tooth enabled glucometer), plus 11 group session and 1 individual session focused on behavioral strategies
BEHAVIORALBehavior intervention with paper diary based self-monitoring
Use paper diaries along with a calorie counter booklet, weight scale, food scale, and pedometer for self-monitoring of diet, physical activity, weight, and blood glucose, plus 11 group session and 1 individual session focused on behavioral strategies
