Testing an Integrated PTSD and Weight Management Intervention: A Hybrid Type 1 Trial

Obesity and post-traumatic stress disorder (PTSD) are common among Veterans. PTSD increases risk for obesity, impacting functioning, health, quality of life, and premature mortality. Use of proven treatments for PTSD and obesity in VA is low. Furthermore, Veterans with PTSD lose less weight than those without PTSD in VA's national weight management program. Based on pilot work, an integrated treatment that combines PTSD and weight management care-using behavioral and pharmacologic approaches-may improve weight and PTSD. Whether it improves these outcomes more than standard VA care is unknown, which is the focus of this study. The study also seeks to understand factors that would interfere with and facilitate implementing the program in VA if it is effective. This Veteran-centered program may be a more efficient and effective treatment for Veterans with PTSD and obesity, addressing both physical and mental health.
