The Veterans Affairs Diabetes Prevention Program (VA-DPP) showed higher participation and 6-month weight loss compared to MOVE! for veterans with prediabetes. However, long-term weight, HbA1c, and health expenditures were similar between the two programs.
Area of Science:
- Health Services Research
- Preventive Medicine
- Behavioral Science
Background:
- The Veterans Health Administration (VHA) offers weight management programs to combat obesity and prediabetes in veterans.
- The Veterans Affairs Diabetes Prevention Program (VA-DPP) and the MOVE!® program are two such interventions.
- This study compared their effectiveness in a real-world clinical setting.
Purpose of the Study:
- To compare the effectiveness of the VA-DPP and MOVE!® weight management programs.
- To assess differences in participation rates, weight change, HbA1c levels, and healthcare expenditures.
- To identify potential improvements for VHA weight management strategies.
Main Methods:
- A prospective, pragmatic, non-randomized comparative effectiveness study.
- Recruited obese/overweight veterans with prediabetes from three VA sites (2012-2014).
- Assessed weight change, HbA1c, and VA health expenditures at 15 months using electronic health records and claims data.
Main Results:
- Higher completion rates for VA-DPP sessions compared to MOVE! (73.3% vs 57.5%).
- VA-DPP participants achieved significantly greater weight loss at 6 months (-4.1 kg vs -1.9 kg).
- No significant differences were found between groups in 12-month weight loss, HbA1c, or VA health expenditures.
Conclusions:
- VA-DPP demonstrated superior short-term engagement and weight loss outcomes.
- Long-term effectiveness regarding weight, HbA1c, and healthcare costs was comparable to MOVE!.
- Incorporating VA-DPP features may enhance the reach and efficacy of VHA weight management programs.
