Impacts of Sugar Warnings on Weight Bias
Sponsor: University of North Carolina, Chapel Hill
Summary
This study aims to examine the effects of added sugar warning labels for sugar-sweetened beverages (SSBs) on explicit weight bias and body weight attributional judgements. Participants will be assigned to view either control labels or added sugar warning labels applied on SSBs in an experimental store. Participants will shop for beverages in the store and take a computer survey during four visits to the store, spaced approximately one week apart.
