About

In adolescents with congenital heart disease physical activity level is reduced which is why promotion to a more active lifestyle with an age-appropriate and modern intervention is needed. In healthy subjects digital health nudging was shown to increase physical activity. However, in adolescents with congenital heart disease such studies have not been conducted yet. In this RCT participants receive daily, short smartphone messages with the primary purpose to increase daily physical activity, which is monitored with a "Garmin vivofit jr." wearable.
