Study Compares VA Weight Loss Interventions for Veterans


BACKGROUND:
Because four out of five Veterans who receive VA healthcare meet the criteria for overweight or obesity, VA patients exemplify the challenging populations for whom effective weight management interventions are needed. In 2006, VA implemented an evidence-based obesity treatment program called MOVE!. However, despite high obesity screening rates across the VA healthcare system (95%), only 10-12% of Veterans who screen positive for obesity enroll in MOVE!. The Aspiring for Lifelong Health (ASPIRE) small-changes weight loss intervention was developed to address the need for effective weight loss treatment for vulnerable populations. This randomized clinical trial evaluated the effectiveness of the ASPIRE intervention by randomly assigning 481 obese Veterans to one of three treatment programs: 1) the ASPIRE-Group program, delivered via in-person groups; 2) the ASPIRE-Phone program, delivered to Veterans via phone; or 3) VA's MOVE! usual care weight management program, delivered primarily in a group format. Veterans were enrolled at two Midwestern VA medical centers starting in January 2010. Investigators assessed data at baseline, 3- and 12-months. Data included: height, weight, and waist measurements; blood pressure; demographics; cholesterol and glucose; and comorbidities, as well as self-reported eating frequency and satisfaction with life.

FINDINGS:

  • All three programs resulted in significant weight loss 12 months afer baseline. Though weight loss was relatively small, ASPIRE-Group resulted in twice the weight loss (-2.8 kg) compared to the other two programs (-1.4 kg each).
  • 20-24% of participants lost 5% of their body weight; with no differences between programs.
  • Both ASPIRE programs (Group and Phone) resulted in more than twice the level of engagement compared to the MOVE! program; ASPIRE-Phone was associated with the greatest engagement.
  • With a few exceptions, there were no differences in secondary outcomes between the three programs. At 12 months, Veterans in all three programs experienced a significant improvement in life satisfaction, HDL, and functional exercise capacity.

LIMITATIONS:

  • Comorbidity information relied on diagnosis codes in administrative data that are often inaccurate.
  • Assessors were not blinded to participant randomization, and might have been unknowingly biased in their collection or recording of data.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
