Balance: A Pragmatic Trial of a Digital Health Intervention to Prevent Weight Gain in Primary Care

Clinical practice guidelines emphasize recommend weight gain prevention, but evidence-based treatments are not available in primary care. Balance, a pragmatic effectiveness trial, will test a scalable treatment approach for medically-vulnerable adults, those who suffer disproportionately from obesity and its adverse health effects. Balance builds on the design and findings of the Shape study (NCT00938535) to test a pragmatic intervention within rural community health centers. Balance will randomize overweight adults and adults with obesity who are patients a local community health center network (Piedmont Health Services) to either: 1) a 12-month weight gain prevention intervention or 2) usual care. Intervention group components include tailored behavior change goals; mHealth self-monitoring and feedback; skills training videos; and stepped responsive coaching from clinic Registered Dietitians. The usual care group will receive standard primary care offered by their providers and automated text messages and health information about maintaining a healthy weight. All intervention components and materials will be provided in Spanish or English.
