Brief Summary
The goal of this online randomized trial is to examine the effectiveness of Front-of-package (FOP) warning labels for added sugar content on the intent-to-purchases of SSBs in an affluent Asian setting. We hypothesize the FOP warning labels are significantly associated with a reduction of consumers' purchase intention of sugar-sweetened beverages (SSBs).
