What this trial studies
In a randomized experiment, about 543 adults who reported drinking at least one sugary beverage in the past week will be assigned to see either added-sugar warning labels or control labels on drinks in an experimental store. Participants will attend four in-person visits about one week apart, shop for beverages in the store, and complete computer surveys at each visit. Investigators will record in-store purchases and self-reported measures to compare the amount of added sugar purchased between groups. Randomization occurs at scheduling and labels are applied to drinks per the assigned arm throughout the visits.
Who should consider this trial
Good fit: Adults age 18 or older who have consumed at least one sugary drink in the past week and can attend four in-person visits are ideal candidates.
Not a fit: People who rarely or never drink sugary beverages or who cannot attend the in-person visits are unlikely to benefit from this intervention.
Why it matters
Potential benefit: If successful, warning labels could reduce the amount of added sugar people buy from sugary drinks, potentially lowering sugar intake and related health risks.
How similar studies have performed: Previous field experiments and survey studies have shown that prominent warning labels can reduce sugary drink purchases or intentions, so this approach has some supporting evidence.
