Front-of-package Warning Labels for Sugar Content in Sugar-sweetened Beverages

Starting soon · Not applicable

Conditions studied: Obesity & Overweight

In brief

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).
