MORINIGO MARTINEZ, Macarena et al. Perception of the influence of front nutritional labeling on the selection and purchase intention of packaged foods in a representative sample of paraguayan adults. Rev. salud publica Parag. [online]. 2022, vol.12, n.2, pp.5-12. ISSN 2307-3349.


The Front-of-Pack (FoP) Nutrition Labelling (NL) of foods and beverages would facilitate healthy purchasing decisions.


To evaluate the perception of the influence of FoP nutrition labelling on food selection and intention to purchase packaged foods in a representative sample of Paraguayan adults, between August and September 2021.

Materials and methods:

Non-masked randomized experimental study, with national representative sample of adults who bought and/or consumed industrialized food products. Healthcare staff and people with linguistic disabilities that make the survey difficult were excluded. Adults were randomly assigned to the different FoP Nutrition Labelling options (A: Octagon Warning, B: Magnifying Glass Warning and C: Traffic Light). Demographic variables, perceived influence of FoP-NL and purchase intention were measured. Descriptive statistics and the proportions test were used. The protocol was evaluated by the FCQ-UNA research ethics committee.


1,106 adults were assigned to one of the options. The median age was 40 years, 83.5% lived in urban areas and 46.2% completed high school. 71.2% indicated that the FoP-NL called their attention, 82% stated that it facilitates the understanding of information, 87.9% perceived a health risk, 56.9% would modify their consumption intention, 70% would modify their intention of purchase and 80% stated that the FoP-NL would be useful to make decisions.


All the FoP-NL were striking for the population, regardless of the type, the three achieve a change in the intention to purchase and consume packaged foods.
