A Mobile Based Diabetes Prevention Program
mDPP Pilot RCT of a Motivational Mobile Diabetes Prevention Program (mDPP)

The goals of the study are to:

  1. Assess effect sizes of our mDPP intervention on improving fasting plasma glucose levels(FPG), weight loss, diet, and physical activity from baseline to 5 months as compared to a control group.
  2. To explore the association between low heath-literacy levels at baseline and adherence to mobile phone usage.
  3. To conduct process evaluation to gain insights into patient compliance to the mobile intervention, including usage barriers and acceptability of our mDPP, at 1 and 5 months using a semi-structured interview method.

The prevalence of type 2 diabetes (T2DM) continues to rise at an alarming rate in the United States. A greater risk of diabetes is observed for ethnic/racial minority and lower socioeconomic status (SES)groups as compared to Caucasians of similar ages. Several clinical trials have tested intensive lifestyle interventions or pharmacologic agents in preventing or delaying T2DM in adults at risk. These trials (e.g.the Diabetes Prevention Program) consistently show impressive diabetes risk reductions using lifestyle interventions, such as relatively modest amounts of weight loss and exercise. However these programs have been expensive to implement and sustain over time in clinical settings or communities.

Mobile technologies are ideal platforms to deliver and disseminate such lifestyle modification programs to a much broader ethnic/racial minority population, making them more cost effective. Today, 87% of adults in the U.S. own a mobile phone. In particular, usage of non-voice services (such as text messaging or mobile internet) in African-Americans and non-white Hispanics is significantly higher than their Caucasian counterparts. In contrast, ethnic /racial minority populations are much less likely to own a computer at home compared to their Caucasian counterparts. Given the rapid diffusion of mobile technologies in ethnic/racial minority populations, we need to understand how to apply mobile persuasive technologies to such lifestyle modification programs.

Masking: Double Blind (Investigator, Outcomes Assessor)
Primary Purpose: Prevention
  • Sedentary Lifestyle
  • Physical Activity
  • Pre-Diabetic
  • Behavioral: Mobile phone based physical activity with intervention
    This group will receive a mobile phone software program and a pedometer. Over a 5-month period, participants in this group will be asked to wear a pedometer, use a mobile phone physical activity and diet diary, and respond to daily physical activity and diet messages or video clips.
  • Behavioral: Pedometer Only
    This group will receive a pedometer. Over a 5-month period, participants in this group will be asked to wear a pedometer.
  • Experimental: PA and Diet Intervention
    5-month physical activity and diet intervention and 6-month maintenance intervention-Plus program
    Intervention: Behavioral: Mobile phone based physical activity with intervention
  • Active Comparator: Pedometer
