Project: Mobile Health Obesity Wellness Intervention in Rural Areas (MOWI)

Grant Number: National institute on Aging K23-AG051681

The national epidemic of obesity affects older adults and is associated with an increased risk of functional impairment, nursing home placement and early mortality. Conventional weight loss programs have the potential to reduce body fat but are difficult to access for older obese adults due to transportation and mobility challenges. The use of technology in older adults with obesity in rural areas has considerable promise.

Our study objective was to gain insights into how a potential Mobile Health Obesity Wellness Intervention (MOWI) in rural older adults with obesity, consisting of nutrition and exercise sessions, could be helpful in improving physical function. The strategy has the potential to improve the health of a rapidly aging demographic with obesity, reduce healthcare costs and if successful, allow program dissemination to distant, remote areas for improvement in healthcare quality.

We have conducted a series of clinical trials evaluating weight loss interventions using remote monitoring, protein supplementation, and the use of telemedicine in delivering care.
