Study Summary
Consumption of sugar-sweetened beverages (SSBs) like sodas, sports drinks, and fruit drinks remains a pressing public health concern in the United States. Consumption of SSBs remains well above recommended levels, and has been linked to obesity, diabetes, and cardiovascular disease. In response, policymakers across the U.S. have proposed requiring warning messages on SSB containers to inform the public and reduce consumption to healthier levels. While online studies find that such warnings reduce intentions to purchase SSBs, no studies have yet examined the impact of warnings on actual consumer behavior. The purpose of this randomized trial is to determine whether health warnings on sugar-sweetened beverages are more effective than control labels at reducing purchases of sugar-sweetened beverages. The trial will take place in a mock convenience store. Participants will be randomly assigned to a health warnings arm in which all sugar-sweetened beverages in the store are labeled with a health warning, or to a control arm in which all sugar-sweetened beverages in the store are labeled with a neutral label. Participants will select items to purchase with cash, and purchases will be compared across trial arms.
Primary Outcome
The primary outcome is calories of sugar-sweetened beverages purchased during the shopping task. Calories from sugar-sweetened beverage purchases is defined as the total number of calories from sugar-sweetened beverages in the participant's basket when they complete the shopping task, calculated as the sum of calories/container for all SSB containers. Purchases will be recorded by the experimenter immediately after the participant completes the \~10-minute shopping task.
