Enhanced Weight Management Program for Veterans With Posttraumatic Stress Disorder: A Randomized Clinical Trial

Area of Science:

• Clinical Psychology
• Obesity Research
• Veterans Health

Background:

• Posttraumatic Stress Disorder (PTSD) is linked to increased obesity risk and challenges in weight management.
• The Veterans Health Administration's (VHA) MOVE! program aims to support weight loss, but veterans with PTSD face unique barriers.

Purpose of the Study:

• To evaluate the effectiveness of a tailored weight management program (MOVE!+UP) compared to the standard MOVE! program for veterans with PTSD and elevated BMI.
• To determine if MOVE!+UP leads to greater weight change than the standard MOVE! program.

Main Methods:

• A randomized clinical trial involving 174 veterans with PTSD and BMI ≥ 25.
• Participants were assigned to either MOVE!+UP (standard behavioral counseling plus PTSD-tailored CBT content and community walks) or standard MOVE!.
• Weight change was assessed at 6 and 12 months by masked assessors.

Main Results:

• No significant difference in weight change was observed between the MOVE!+UP and MOVE! groups at 6 months (adjusted mean difference: -1.5 lb).
• Secondary outcomes, including PTSD symptom changes and 12-month weight change, also did not differ significantly between groups.
• The trial reported no adverse events leading to participant withdrawal.

Conclusions:

• The MOVE!+UP program did not demonstrate superior weight loss compared to the standard MOVE! program in veterans with PTSD.
• These findings highlight the need for continued research into effective weight management strategies for individuals with PTSD.
• Addressing the complex interplay between PTSD and obesity remains a critical area for clinical intervention and study.
