Completion Date
2/1/2028
Summary
This study aims to examine the effects of added sugar warning labels on sugary drinks. Participants will be assigned to view either added sugar warning labels or control labels, applied on sugary drinks in an experimental store. Participants will shop for beverages in the store and take a computer survey at 4 visits spaced approximately 1 week apart.
Detailed Description
This study aims to determine whether new added sugar warnings on sugary drinks lead to decreased amount of added sugar purchased from sugary drinks. The investigators aim to enroll approximately 543 adults ages 18 and older who have consumed at least one sugary drink in the past week. Participants will attend 4 in-person study visits at the study experimental store, spaced approximately 1 week apart. Participants will be randomized to 1 of 2 trial arms at the time of scheduling. At the first visit, participants will provide written informed consent. At each study visit, participants will shop for beverages in the store and take a computer survey. Participants will view sugary drinks in the store labeled per their trial arm. Researchers will record in-store purchases, and other self-reported measures will be assessed via the computer surveys.
