Fit for Duty: mHealth Intervention for Weight Gain Prevention
Sponsor: University of North Carolina, Chapel Hill
Summary
Weight gain is disproportionately high among young adults compared to other age groups and of particular concern in the military, which is comprised largely of young adults, as obesity has emerged as a threat to national security. Despite the critical need to address weight gain in young military personnel who can face discharge for failing to meet weight standards, there is currently no evidence-based programs available to them. This study aims to adapt an evidence-based weight gain prevention intervention for delivery in a young adult, active-duty military population using mobile technology to prevent weight gain over 2 years .

Fit for Duty-mobile participants will receive self-regulatory support and behavior change techniques via an initial core intervention delivered through a native smartphone app (includes connected device data, 10 weekly lessons, weekly tailored feedback) and 4 coaching calls (weeks 1, 4, 8, and 16). App based tailored feedback and messaging will continue through 2 years. Optional 4-week refresher e-campaigns are offered every 6 mos. after the initial core intervention. Participants choose to follow either a Small Changes approach or a Large Changes approach and may choose to switch approaches over the 2 years, if desired.
