What this research studies

If I join, I'll shop at a small research convenience store in North Carolina and buy beverages for my household four times over four weeks, using my own money. Participants are randomly assigned to see either sugar warning labels on sugary drinks or neutral labels. The study measures total sugar purchased from drinks and other choices like juice or diet beverages. A subset of participants will do interviews and surveys to help researchers understand why labels might change shopping decisions.

Who could benefit from this research

Good fit: Adults who buy beverages for their household, live near Chapel Hill/North Carolina, and are willing to visit the research store four times are ideal candidates.

Not a fit: People who do not drink or buy sugar-sweetened beverages, cannot attend in-person visits, or are underage would likely not benefit from participating.

Why it matters

Potential benefit: If successful, this could support warning labels that help people reduce how much sugar they buy and consume from drinks.

How similar studies have performed: Previous laboratory and online studies have shown promising effects of sugar warnings, but results from realistic in-person shopping trials in the U.S. are limited.
