Texting for Mobility in Overweight/Obese Adults With Peripheral Artery Disease

Text Messaging to Promote Mobility in Overweight/Obese Adults With Peripheral Artery Disease

By doing this study, researchers hope to learn about the feasibility of using a mobile application to help overweight or obese adults with PAD increase their walking distance and lose weight.

Peripheral artery disease (PAD) or poor leg circulation affects 8 to 12 million Americans including non-Hispanic Whites, African Americans and Latinos. Having PAD can limit how far you can walk. Many patients with PAD are also overweight or obese. Weight loss among overweight or obese adults with PAD may improve walking distance. Given how common obesity or being overweight is among persons with PAD, interventions are needed to address weight loss in this population.
