Helping people with PAD and obesity improve walking and prevent mobility loss

1/2 + PROmote weight loss in obese PAD patients to preVEnt mobility loss: the PROVE Trial

NIH-funded research Northwestern University · NIH-10891372

This research explores if combining weight loss with walking exercise can better improve walking ability for people with peripheral artery disease (PAD) who are also overweight or obese.

What this research studies

Many people with peripheral artery disease (PAD) are also overweight or obese, which can make walking more difficult and lead to faster declines in mobility. While walking exercise is a common treatment for PAD, early findings suggest that adding weight loss might offer even greater benefits. This project will test if a special weight loss program, combined with exercise, can improve walking ability more effectively than exercise alone. The weight loss program includes group support, mobile technology, remote coaching, and a specific diet plan.

Who could benefit from this research

Good fit: Ideal candidates are individuals with lower extremity peripheral artery disease (PAD) who are also overweight or obese (BMI > 28 kg/m2).

Not a fit: Patients who are not overweight or obese, or those without peripheral artery disease, would likely not benefit directly from this specific intervention.

Why it matters

Potential benefit: If successful, this approach could provide a new and more effective way for overweight or obese PAD patients to improve their walking and maintain their independence.

How similar studies have performed: Observational data and a pilot study have shown promising results for combining weight loss with exercise in this population, but a full-scale test of this specific intervention is needed.
