Abstract
INTRODUCTION: The objective of our study was to evaluate the cost-effectiveness of a community-based intervention designed to improve physical activity levels and dietary intake and to reduce diabetes risk in a largely Hispanic population residing along the U.S.-Mexico border. METHOD: We forecasted disease outcomes, quality-adjusted life-years (QALYs) gained, and lifetime costs associated with actual and projected attainment of 2% and 5% weight loss taking a societal cost perspective. We extrapolated changes in beverage calorie consumption between baseline and 6-month follow-up to attain projected weight loss measures. Outcomes were projected 5, 10, and 20 years into the future and discounted at a 3.0% rate. RESULTS: The incremental cost-effectiveness ratio was $57,430 and $61,893, respectively, per QALY gained when compared with usual care for the 2% and 5% weight loss scenarios. The intervention was particularly cost-effective for morbidly obese participants. Cost-effectiveness improves when using 3-year weight loss projections based on changes in sugar-sweetened beverage caloric consumption to $49,478 and $24,092 for the 2% and 5% weight loss scenarios. CONCLUSIONS: This analysis demonstrates that a culturally sensitive community-based weight loss and maintenance intervention can be cost-effective even when healthy weight individuals participate.
