About this study
Official title: Consumer Attitudes and Understanding of Low Sodium Claims on Food: An Analysis of Healthy and Hypertensive Individuals
Sodium-related claims on food labels should help people find lower sodium food choices; however consumer attitudes and understanding of such claims are unknown.
The objective of this study was to evaluate: 1) the attitudes and understanding to different types of permitted sodium claims and 2) the effect of hypertension on responses to such claims.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Mock package questionnaireBehavioural
Within a online questionnaire we exposed participants randomly to 4 mock packages differing only by the nutrition claim it carried and asked participants to answer several questions on attitudes and understanding after each mock package.
| Study group | Role | What they receive |
|---|---|---|
| Canadian Consumer Monitor Panel | Canadian Consumer Monitor Panel is a online consumer monitor panel which answers surveys every 8-10 weeks about diet and health. Receives: Behavioral: Mock package questionnaire |
What is being measured
The primary outcome is the main question the study is designed to answer.
Response to survey questions measuring attitudes towards sodium claims using 5 point likert rating scales
Within an online survey, participants were exposed to 4 mock soup packages that differed only by the claim it carried. After being exposed to each mock package, participants were asked to rate their perceived attractiveness, healthiness, credibility, usefulness of the tested sodium claims using 5 point likert scales. Participants were also asked to rate their purchasing intentions of the mock soup product with the different sodium claims.
Measured: On average the survey took 25 minutes to complete
Response to survey questions evaluating participants understanding of sodium claims
After each mock package, understanding of sodium claims was evaluated using various survey methods. First, participants were asked to rate their perceived clarity of the wording of the claim using a 5 point likert scale (a subjective measure of understanding). Second, participants were ask to rate, on 5 point likert scales, the perceived benefit of consuming the mock package for subgroups with different health conditions (an indirect measure of understanding). Finally we asked participants, in an open ended question, to explain what a claim means to a friend (an objective measure of understanding).
Measured: On average the survey took 25 minutes to complete
