About this study
Official title: A Randomized Controlled Trial Using FoodFlip©, a Mobile Phone App, to Promote Healthier Diets and Food Choices Among Post-Secondary Students
Canada passed mandatory front-of-package labelling (FOPL) regulations where pre-packaged food and beverage products that are high in sugar, saturated fat, and/or sodium are required to display a 'high-in' front-of-pack nutrition symbol (NS). FOPL is an effective tool to inform consumers about products that can harm health and help guide their purchasing decisions. However, as the regulations are limited to the pre-packaged food supply and do not apply to restaurants and other food services, little is known about the potential impact of the NS in such settings. Therefore, the objective of the present study is to investigate the impact of the Canadian FOPL (i.e. the 'high-in' NS) as delivered through a mobile health (mHealth) app in a setting currently not subject to regulations. The study will take place on a post-secondary campus (University of Toronto) hosting students, a population vulnerable to poor dietary choices, nutritional knowledge, and associated weight gain. A 2-week long, randomized controlled trial with a 3-parallel arm study design will be conducted to explore the effect of the 'high-in' NS on students' purchasing behaviours and nutritional knowledge. Eligible participants will be randomly allocated into one of 3 intervention groups: no App control; App control with no NS; App with NS. Questionnaires will be used to assess nutritional knowledge, and receipts will be used to analyze purchasing behaviour.
Read the detailed description
Poor diets increase the risk of non-communicable diseases (NCDs), one of the major causes of disability and premature mortality in Canada. To help improve the diets of Canadians, Health Canada recently promulgated front-of-pack labelling (FOPL) regulations, which mandate pre-packaged foods and beverages meeting and/or exceeding the thresholds for nutrients of public health concern (i.e., sugars, saturated fat, and/or sodium) to display a 'high-in' front-of-pack nutrition symbol (NS). Moreover, previous studies have shown that FOPL can improve purchasing behaviours of consumers by decreasing purchases of nutrients of public health concern and/or foods carrying 'less healthy' FOPL and increase the nutritional knowledge of consumers. However, the FOPL regulations do not address restaurant foods, which are significant caloric contributors to the Canadian diet and are often high in nutrients of public health concern. Further, FOPL regulations do not address foods sold in other institutional settings, including schools, long-term care homes, and daycares. This policy gap may adversely affect the young adult population - a group notably vulnerable to poor diets and associated weight gain and poor nutritional knowledge. Emerging evidence suggests that FOPL can be an effective tool to communicate nutrition information to promote healthier food choices in food service settings; however, limited data exist on the effectiveness of FOPL on menu items available on post-secondary campuses to influence students' food purchasing behaviours on campus and to improve their nutritional knowledge. Furthermore, nutrition mobile health (mHealth) apps have been shown to have the potential to support behavioural change, improve nutrition knowledge, and develop skills to promote healthy eating behaviours through quick information-sharing capacity, customizable tracking abilities, and interactive components. The L'Abbe Lab has developed a mobile application, FoodFlip©, that provides nutrition information at the point of purchase to influence the decision-making process with high usability and functionality in grocery shopping settings. However, the application of FoodFlip© on purchasing behaviours in post-secondary campus settings is unknown. Therefore, the primary objective of the study is to investigate the effect of the Canadian FOPL (i.e., the 'high-in' nutrition symbol) on purchasing behaviours and nutritional knowledge of post-secondary students on campus, using the FoodFlip© App.

What is being measured
The primary outcome is the main question the study is designed to answer.
Purchasing Behaviors
Purchasing behaviours will be assessed using receipts and/or records provided by participants over the 2-week study period. Nutritional quality of purchased menu items will be determined using a nutrient profiling model based on the thresholds for Canada's FOPL regulations. Menu items will be assigned a "Menu item score" on a scale of 0 (minimum) to 3 (maximum), with 0 indicating no 'high-in' nutrients and 3 being 'high-in' all 3 nutrients-of-concern. Scores of each menu item purchased will be summed and divided by the total number of purchases to derive the final score for each participant; higher scores mean lower nutritional quality (i.e. worse outcome) and lower scores mean higher nutritional quality (i.e. better outcome). The final scores will then be compared between intervention groups, and change in nutritional quality will be compared within intervention groups at 2 time points: early intervention (end of Week 1) and late intervention (end of study period).
Measured: 2 weeks
Nutritional Knowledge
Nutritional knowledge will be assessed using an online questionnaire developed and validated by the L'Abbe Lab. Questionnaire will be completed by participants at 1) baseline and 2) end-of-study. This short (10-15 min) survey of 30 short questions will include questions assessing health literacy and nutritional knowledge that have been adapted from validated questionnaires. Correct answers will be coded as "1" while incorrect answers will be coded as "0", with a maximum of 30 points. Higher scores indicate higher nutritional knowledge (i.e. better outcome), and lower scores indicate lower nutritional knowledge (i.e. worse outcome). Between intervention groups differences in nutritional knowledge will be assessed using ANOVA, while changes in nutritional knowledge from baseline to end-of-study will be compared within intervention groups using Mann-Whitney U-tests.
Measured: 2 weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Canada passed mandatory front-of-package labelling (FOPL) regulations where pre-packaged food and beverage products that are high in sugar, saturated fat, and/or sodium are required to display a 'high-in' front-of-pack nutrition symbol (NS). FOPL is an effective tool to inform consumers about products that can harm health and help guide their purchasing decisions. However, as the regulations are limited to the pre-packaged food supply and do not apply to restaurants and other food services, little is known about the potential impact of the NS in such settings. Therefore, the objective of the present study is to investigate the impact of the Canadian FOPL (i.e. the 'high-in' NS) as delivered through a mobile health (mHealth) app in a setting currently not subject to regulations. The study will take place on a post-secondary campus (University of Toronto) hosting students, a population vulnerable to poor dietary choices, nutritional knowledge, and associated weight gain. A 2-week long, randomized controlled trial with a 3-parallel arm study design will be conducted to explore the effect of the 'high-in' NS on students' purchasing behaviours and nutritional knowledge. Eligible participants will be randomly allocated into one of 3 intervention groups: no App control; App control with no NS; App with NS. Questionnaires will be used to assess nutritional knowledge, and receipts will be used to analyze purchasing behaviour.

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Purchasing Behaviors (time frame: 2 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06033911, which also lists 20 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Mar 2025.
