About this study

Official title: The Effect of an Application-based Health Intervention (FoodCoach) on Food Purchases in Switzerland: Randomized Controlled Trial

The FoodCoach study is a 9-week randomized controlled trial from the University of St.Gallen and the University Hospital of Bern, supported by the Swiss National Science Foundation #188402 and by Sanitas Management AG. Sanitas Management AG supports the recruiting of study participants without interfering with the study content.

FoodCoach aims to investigate the effectiveness of improving people's food shopping healthiness by providing automated food shopping recommendations. The results of the study could possibly help improve the health status of the Swiss population and beyond in a low-cost and automated manner.

The investigators collect participant grocery data via the loyalty card programs "Migros Cumulus" and "Coop Supercard" after obtaining participants' informed consent. From this data, the investigators generate automated recommendations that are based on the Nutri-Score framework and expertise of dieticians at the University Hospital of Bern. After sign-up, participants are randomized into a treatment and a control group. The treatment group receives automated recommendations via the FoodCoach Web Application, while the control group only receives a report about their food shopping by email after the intervention phase. Both groups need to finish the same onboarding survey where the investigators collect basic demographic information. After the intervention, the treatment group will receive a post-study survey containing two parts via email. Part 1 includes questions about the ease of use, interface and satisfaction and usefulness of the FoodCoach app. Part 2 includes questions about the participants' weight and height, the motivation to shop healthily and sustainably. The control group will receive a post-study survey which only contains part 2 as described before via email.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

    The FoodCoach app displays transparent analysis and recommendations regarding participant's food purchases recorded on their loyalty cards. It tries to help participants understand why and how they should/can shop more healthily, motivating them to change their unhealthy food purchase behavior.

Study groups in NCT05597969
Study groupRoleWhat they receive
FoodCoachExperimentalThe experimental group uses the FutureMe app for 9 weeks and continue to voluntarily use it. The app has the following functionality: * Dashboard: show the Nutri-Score changes over the last 10 baskets and comparisons between the specific user and all FoodCoach app users. * Recommendations: show three recommendations regarding their food purchases and healthier product recommendations to help them achieve these recommendations. * Nutrition Analysis: show the monthly energy contribution of 7 food categories in the past 6 months. * Spending Analysis: show the monthly expense contribution of 7 food categories and 1 not categorized category in the past 6 months. * Shopping history: show their purchase history in the past 6 months, together with monthly average Nutri-Score and basket Nutri-Score if applicable * Q \& A: show answers to the commonly asked questions. E.g., how is the Nutri-Score calculated?
Receives: Behavioral: FoodCoach
ControlNo interventionThe control group receives no application for use. They need to finish the onboarding survey, donate their food purchase data and finish the post-study survey (voluntary). They receive no intervention while the experimental group should be actively using the FoodCoach app. The investigators will send them an analysis report of their food purchase data via email in 3 months after the intervention phase is gone. Note the intervention lasts for 9 weeks.
