Summary
The aim of this study is to determine the degree to which sugar-sweetened beverages (SSB) warning labels increase consumers' knowledge about the potential health harms of SSBs and reduce SSB purchases and consumption. 216 racially and ethnically diverse parents of children 6-11 years old will be recruited to buy snacks and beverages for four weeks via an online store that ships participants their purchases. Participants will be randomized to either 1) calorie labels (control); or 2) sugar graphic warning labels. The investigators hypothesize that sugar graphic warning labels displayed in an online store in weeks 2-4 will lead to the greatest reductions from week 1 across both primary outcomes compared to the control group that will only see calorie labels.
