Official title
Front-of-package Warning Labels for Sugar Content in Sugar-sweetened Beverages: An Online Randomized Experiment
Overview
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).
Interventions
- Other UK-style traffic light labels
UK-style traffic light labels displaying "HIGH ADDED SUGAR" in a red circle, "MEDIUM ADDED SUGAR" in a yellow circle, "LOW ADDED SUGAR" in a green circle, or "ZERO ADDED SUGAR" in a green circle - Other Chile-style octagonal labels
Chile-style octagonal labels displaying "HIGH ADDED SUGAR" - Other text warning labels
text warning labels stating that drinking beverages with added sugar contributes to diabetes and tooth decay, applied to low-, medium-, and high-added-sugar beverages - Other text-and-graphic warning labels
text-and-graphic warning labels displaying the same message as the text warning label with simple graphics representing diabetes and tooth decay, applied to low-, medium-, and high-added-sugar beverages - Other teaspoon labels
teaspoon labels showing the number of teaspoons of added sugar per 100 mL, applied to all added-sugar levels - Other Hong Kong-style labels
Hong Kong-style labels, adapted from the voluntary "Salt / Sugar" Label Scheme for prepackaged food products, displaying "LOW SUGAR" or "NO SUGAR" inside a diamond shape with a tick mark at the bottom
