Run by George Washington University · NCT07249008 · Data updated 2026-11-12
This test will see if different front-of-package warning labels about non-sugar sweeteners change what Brazilian parents pick for their 2–12 year-old children's yogurts, drinks, granola and cereal bars.

Is this trial a fit for you?
✓Likely a good fit
Adults aged 20 or older who live in Brazil, are parents or guardians of a 2–12 year-old child, are primarily responsible for grocery shopping, and can read Portuguese.
✕Probably not a fit
People who are under 20, not parents/guardians of a 2–12 year-old, not the primary grocery shopper, unable to read Portuguese, or who do not live in Brazil would not be eligible and would not benefit from participating.

What this trial studies
This online randomized experiment enrolls Brazilian parents who do most of the household grocery shopping and asks them to choose one yogurt, three beverages (for breakfast, lunch, and dinner), one granola and one cereal bar for their child. Participants are randomly assigned to one of three arms: no non-sugar sweetener (NSS) label (control), a NSS warning label modeled on Mexico's label, or the magnifying-glass NSS label used in Brazil. Recruitment uses a nationwide online panel with quotas for education, race and geography to approximate the national profile. The primary outcome is how label exposure changes product selections for children aged 2–12.
Why it matters
Potential benefit: If successful, the results could inform labeling policies that help parents choose fewer products with non-sugar sweeteners for their children and improve dietary choices.
How similar studies have gone: Other front-of-package labeling studies (for sugar, salt and calories) have changed consumer choices and purchases, but applying NSS-specific warnings is relatively new and less extensively tested.
