Implementation Science Is Important for Understanding and Advancing Beverage Taxes


Bleich, Sara N.; Chriqui, Jamie F.; & Ng, Shu Wen (2020). Implementation Science Is Important for Understanding and Advancing Beverage Taxes. American Journal of Public Health, 110(9), 1266-1267. PMCID: PMC7427245


Results from rigorous evaluations of beverage taxes in seven localities in the United States and in more than 40 countries are mounting rapidly. These studies provide evidence to policymakers looking to take action on reducing consumption of sugary beverages, which are linked to several adverse health outcomes such as obesity and type 2 diabetes and are disproportionately consumed by low-income and racial/ethnic minority populations. Together, these studies point to consistent increases in price (with variation by store type and geographic location) and reductions in sales of taxed beverages (with variation in the magnitude of the decline). Results from Philadelphia, Pennsylvania, and Mexico further suggest that beverage taxes may help people with lower income or education levels more than those with higher levels. Some evidence also points to reduced consumption of sugary beverages following implementation of beverage taxes, although this literature is mixed. With respect to health outcomes, microsimulation studies predict significant reductions in obesity and cardiovascular disease as a result of beverage taxes.
