Estimating State-level Cost-effectiveness of a Sugar-sweetened Beverage Excise Tax
Methods: This study provides Maine-specific estimates of the cost-effectiveness of a one-cent per ounce SSB excise tax using local data inputs for the national Childhood Obesity Intervention Cost Effectiveness Study (CHOICES) microsimulation model. Healthcare costs averted and cost-effectiveness of ten-year reductions in body mass index (BMI), childhood obesity prevalence and gains in quality-adjusted life years (QALYs) will be estimated for the 2015 U.S. and Maine populations. Maine estimates of SSB prices will be collected in 2015 from a sample of stores and restaurants. Estimates of baseline SSB intake from the National Health and Nutrition Examination Survey will be adjusted for Maine using regional data. Costs of tax administration will be estimated based on interviews with local stakeholders.
Results: Nationally, a one cent per ounce SSB excise tax would decrease consumption by 20% and mean BMI by 0.16 (95% Uncertainty Interval (UI): 0.06; 0.37) units among youth. The tax would generate $12.5 billion in annual revenue nationally (95% UI: $8.92; $14.1 billion). Maine-specific results and national results on healthcare cost savings and cost-effectiveness to reduce childhood obesity and increase QALYs will be presented.
Conclusions: This study highlights the potential to adapt national simulation models of nutrition policy changes to a specific state context in order to inform the local nutrition policy-making process.
