Higher socioeconomic status (SES) households exhibit a greater reduction in high-sugar beverage purchases in response to SSB tax increases compared to lower SES households.
Policymakers should investigate why low-SES households are less responsive to SSB taxes. If they are not reducing consumption, the tax may be purely regressive without the intended health benefit, requiring targeted interventions.

this change was greater among high socioeconomic status (SES) households.

More from this paper
- Implementing a small incremental increase in sugar-sweetened beverage (SSB) tax rates (e.g., 13% to 18%) results in only small price increases and small reductions in SSB purchases, which is unlikely to significantly reduce obesity or noncommunicable diseases.Good
- Decreasing the tax rate on low-sugar or artificially sweetened beverages (L-SSBs) leads to a significant increase in their purchase volume, potentially offsetting the health benefits of reduced high-sugar beverage consumption.Good
