Sugar-sweetened beverages (SSBs) are associated with a wide array of adverse cardiometabolic health outcomes. While research indicates that beverage taxes reduce purchases of SSBs, the impact of these taxes on total sugar purchased has received less attention. Substitution to untaxed beverages and high-sugar foods has important implications for potential health impacts. Additionally, apart from the economic (dis)incentive of a price increase, the mechanisms through which taxes influence individuals' purchasing behavior, such as by changing perceptions of beverages, remain unclear.Using a longitudinal panel of U.S. households, we examined changes in volume and sugar purchases from beverages in Philadelphia and San Francisco, the two largest U.S. cities with beverage taxes. We used a difference-in-difference approach to compare purchases up to three-years post-tax implementation in Philadelphia and San Francisco compared to propensity-score matched households. We then evaluated changes in sugar and energy from food and beverages purchased to understand substitution and net effects. Finally, we analyzed repeated cross-sectional data from customer surveys in Philadelphia and a control city (Baltimore), to assess perceived healthfulness of specific beverages pre-tax and one- and two-years post-tax implementation. In pooled analyses, volume and sugar from taxed beverages declined by 25% and 27% post-tax, respectively, with no change in the overall volume or sugar from untaxed beverages, although in city-specific analyses, sugar from untaxed beverages increased in Philadelphia. We found no change in total sugar from foods or high-sugar food categories, except for an increase in purchases of sweeteners (e.g., sugar). Additionally, we observed increases in the probability of perceiving taxed beverages as unhealthy in Philadelphia post-tax, relative to Baltimore, driven by changes in stores in low-income neighborhoods.This work demonstrates the impact of city-level beverage taxes on consumer purchases and perceptions. Overall, sugar from taxed beverages decreased post-tax, although some substitution to high-sugar untaxed beverages in Philadelphia and increases in purchases of sweeteners also occurred. Perceived healthfulness of taxed beverages decreased, implying that the tax had a health signaling effect. Our findings suggest that beverage taxes can reduce sugar from beverage purchases, and underscore the need for complementary policies to meaningfully improve diet quality and health outcomes.
