Supreme Nudge trial combines nudging with a walking app to improve health

Published on March 23, 2022 – Unhealthy food choices and insufficient physical activity are more common in adults with a low socioeconomic position, leading to an increased risk of cardiovascular disease. The Supreme Nudge intervention tries to achieve long-term behavioral change in this target group.

Within the Supreme Nudge research project, a supermarket intervention has been developed in which the store environment is arranged in such a way that healthy food choices become the easy choice by means of nudging and pricing strategies. This is combined with an intervention in which participants receive tailored coaching messages through a smartphone app to encourage them to walk more. This mobile walking coach gives users real-time feedback on the number of steps they have already taken and context-specific advice on walking opportunities in their surroundings. For example, a user will receive an encouragement to go for a walk in a nearby park to meet his or her daily step goal whenever the app registers that he/she is within close proximity.
