Objective |
In a national cohort of Veterans, weight change was compared between participants in a US Department of Veterans Affairs (VA) behavioral weight management program (MOVE!) and matched non-participants, and between high-intensity and low-intensity participants.
Methods |
Retrospective cohort study of Veterans with 1 + MOVE! visits in 2008–2017 were matched to MOVE! non-participants via sequential stratification. Percent weight change up to two years after MOVE! initiation of participants and non-participants was modeled using generalized additive mixed models, and 1-year weight change of high-intensity or low-intensity participants was also compared.
Results |
MOVE! participants (n = 499,696) and non-participant controls (n = 1,336,172) were well-matched, with an average age of 56 years and average BMI of 35. MOVE! participants lost 1.4 % at 12 months and 1.2 % at 24 months, which was 0.89 % points (95 % CI: 0.83–0.96) more at 12 months than non-participants and 0.55 % points (95 % CI: 0.41–0.68) more at 24 months. 9.1 % of MOVE! participants had high-intensity use in one year, and they had 2.38 % point (95 % CI: 2.25–2.52) greater weight loss than low-intensity participation at 12 months (2.8 % vs 0.4 %).
Conclusions |
Participation in VA’s system-wide behavioral weight management program (MOVE!) was associated with modest weight loss, suggesting that program modifications are needed to increase Veteran engagement and program effectiveness. Future research should further explore how variations in program delivery and the use of newer anti-obesity medications may impact the program’s effectiveness.

• | Over 20 years, MOVE! program users had greater weight loss than non-users. |
• | The 9 % of users with greater participation experienced greater weight loss. |
• | Research is needed to more effectively engage Veterans to participate in MOVE!. |
