NCT04567004

Brief Summary

Purpose: To better understand the impact of different front-of-package labels (FOPLs) on consumer purchasing intentions and ability to identify unhealthy foods. Participants: \~8,000 Colombians, recruited from Offerwise, that are 18 years or older. Procedures (methods): Participants will be randomly assigned to view images of food and drink products with either a nutrient warning label, Guideline Daily Amount label, Nutriscore label, or no-label control. They will be asked a series of questions about the products and the labels (excluding control group) on them. Questions will also include standard demographic and health related variables.

Outcome Measures

Primary Outcomes (2)

  • Selection of Product Higher in Sugar

    Percentage of participants who select the less healthy product in a set of two products as the product the consumer most wants to buy.

    During ~15 minute online survey

  • Correct Identification of the Product Higher in Sugar

    Percentage of participants who correctly select the product higher in sugar (between two products)

    During ~15 minute online survey

Secondary Outcomes (5)

  • Perceived Message Effectiveness

    During ~15 minute online survey

  • Purchase Likelihood

    During ~15 minute online survey

  • Identify Less Healthy Product

    During ~15 minute online survey

  • Ability to Identify Product as Having Excess of Sugar/Saturated Fat/Sodium

    During ~15 minute online survey

  • Most Discouraging Label

    During ~15 minute online survey

Study Arms (4)

Control

OTHER

The control arm will show the products with no label.

Other: Control

Nutriscore Label

EXPERIMENTAL

The Nutriscore label applies a letter grade (A, B, C, D or E) to a product based on certain nutrient criteria.

Other: Nutriscore Label

Adapted Peruvian Nutrient Label

EXPERIMENTAL

The adapted label is a black octagon with the words in Spanish saying "Excess of sugar,"Excess of saturated fat," or "Excess of salt/sodium" depending on the nutrition contents of the product. Below the octagon is a box with words in Spanish saying "Avoid high consumption"

Other: Adapted Peruvian Nutrient Label

Guideline Daily Amount Label

EXPERIMENTAL

The Guideline Daily Amount label highlights the nutrient contents of the product by serving. It lists the calories, total fat, saturated fat, sugar, and sodium, as well are their % of the daily value.

Other: Guideline Daily Amount Label

Interventions

ControlOTHER

Participants will be shown images of juice, bread, yogurt, cookies, and cereal without any added front-of-package labels.

Control

A front-of-package Nutriscore label will be applied to images of juice, bread, yogurt, cookies, and cereal. This label applies a score of A, B, C, D, or E based on the product's nutrition profile.

Nutriscore Label

A front-of-package octagonal nutrient label will be applied to images of juice, bread, yogurt, cookies, and cereal. The label text informs consumers if a product is high in sugar, saturated fat, or salt/sodium. These labels were developed by the Peruvian government and adapted by investigators.

Adapted Peruvian Nutrient Label

A front-of-package Guideline Daily Amount label will be applied to images of juice, bread, yogurt, cookies, and cereal. The label shows the amount and percent of daily value of calories, total fat, saturated fat, sugar, and sodium in one serving of a product.

Guideline Daily Amount Label
