About this study
Official title: Effects of a Non-sugar Sweetener Label on Parents' Selection of Foods and Beverages in Brazil: a Randomized Clinical Trial.
The purpose of this study is to assess the impact of non-sugar sweeteners (NSS) front-of-package labels (FOPL) on Brazilian parents' food and beverage selections for their children. The study includes three arms: 1. no NSS FOPL control group, 2. a group exposed to a NSS FOPL modeled after the Mexican warning label for NSS, and 3. a group exposed to a NSS FOPL using the magnifying glass symbol currently implemented in Brazil for nutrients of public health concern. Participants will be instructed to select products for their child, including one yogurt, three beverages (for breakfast, lunch, and dinner), one granola, and one cereal bar.
- Conditions
- Control Group, Mexico-based NSS FOPL, Brazil-based NSS FOPL
- Being tested

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Experimental : Mexico-based NSS FOPLOther
Participants view the online store with the Mexican-style non-sugar sweetener front-of-package label on eligible products
Experimental : Brazil-based NSS FOPLOther
Participants view the online store with the magnifying glass non-sugar sweetener front-of-package label like the one used in Brazil
| Study group | Role | What they receive |
|---|---|---|
| Control | No intervention | Participants view the online store without any non-sugar sweetener front-of-package label |
| Mexico-based NSS FOPL | Experimental | Participants view the online store with the Mexican-style non-sugar sweetener front-of-package label on eligible products Receives: Other: Experimental : Mexico-based NSS FOPL |
| Brazil-based NSS FOPL | Experimental | Participants view the online store with the magnifying glass non-sugar sweetener front-of-package label like the one used in Brazil Receives: Other: Experimental : Brazil-based NSS FOPL |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of products selected that are unsweetened or low in added sugars
Selection of products that do not contain NSS or added sugars, or that contain added sugars below the FOPL threshold (i.e., less than 10 g per 100 g) for granola and cereal bars.
Measured: Day 1
Secondary outcomes (1)
Percentage of products selected that contain NSS and high added sugars
Selection of products containing both NSS and are high in added sugars, defined as those displaying the FOPL for added sugars (i.e., more than 7.5 g per 100 ml for liquids, and more than 10 g per 100 g for foods).
Measured: Day 1
