Brief Summary

This project will test the efficacy of the "TRIMM" (Tailored Rapid Interactive Mobile Messaging) program, a user-friendly, semi-individualized text-messaging intervention to facilitate lifestyle change and weight loss among obese African-American adults with or at risk for diabetes, in a pilot, controlled clinical trial.

The text-messaging intervention will be in addition to, and compared with traditional diet, behavior, and physical activity education. Tips will be designed to increase knowledge, skills, and motivation.

Detailed Description

Type-2 diabetes, and its most important risk factor, obesity, have become major strains on our nation's health care system. By 2050, one in three U.S. adults could have diabetes (Stobbe, 2010), and obesity currently contributes nearly 17% of U.S. medical costs (Cawley, 2010). Our nation's underserved urban minority populations disproportionately suffer from type-2 diabetes and obesity. African-Americans, for example, comprise 12% of the US population but 23% of the extremely obese (Livingston, 2004). To reduce diabetes, obesity must be addressed. Unfortunately, traditional obesity interventions are intrusive and costly.

This project will test the efficacy of the "TRIMM" (Tailored Rapid Interactive Mobile Messaging) program, a user-friendly, semi-individualized text-messaging intervention to facilitate lifestyle change and weight loss among obese African-American adults with or at risk for diabetes, in a pilot, controlled clinical trial.

The text-messaging intervention will be in addition to, and compared with traditional diet, behavior, and physical activity education. Tips will be designed to increase knowledge, skills, and motivation. Participants will have the option to receive spiritually-based messages, if desired.

166 overweight or obese men and women will be recruited from 10 Baltimore inner-city churches, and will be assigned to one of two, six-month lifestyle-change programs. Participants must be overweight, aged 21-65, and own a cell phone with text-messaging capability. To be eligible for the study, participants will need to first pass a health screening and meet other study criteria.

The McKesson Foundation is funding this study, which has a total of 5 visits, ranging from ½ hr. to 3 hrs. The active intervention will last 6 months, with a follow-up visit at month 12. The TRIMM Program will feature periodic, individualized text messages and feedback via the participant's mobile phone as well as periodic follow-up appointments. The traditional program will consist of traditional diet, behavior, and physical activity education.

Qualified participants will receive individualized weight-loss plans and monetary compensation for their time, effort, & parking.

The long-term goal is to demonstrate, using a real-life setting, the potential superiority in efficacy of a specific mHealth application (text-messaging) for an underserved population at high risk of type-2 diabetes, compared to traditional, often more costly, and currently underutilized lifestyle-change interventions.
