Congenital heart disease (CHD) affects approximately 1% of live births, and children with CHD often fail to meet WHO physical activity guidelines. Digital interventions to promote physical activity in CHD patients are limited. This study will develop and test a 12-week digital lifestyle intervention for children (ages 8-13) and their guardians, using a Garmin Vivofit Jr. 2 wearable to continuously monitor physical activity (PA). We will assess its impact on children's moderate to vigorous intensity physical activity (MVPA), daily activity (steps per day), quality of life, nutrition, and health literacy, as well as the quality of life and health literacy of their parents.

RECRUITINGPhysical activity
Physical activity is objectively assessed with the wrist worn wearable "Garmin vivofit jr. 2". Daily physical activity is measured on the basis of active minutes in moderate-to-vigorous intensity.
Time frame: 12 weeks
Daily step count
Children's daily step count is objectively assessed using the wrist-worn wearable device, Garmin Vivofit Jr. 2.
Time frame: 12 weeks
Health-related quality of life
Children's health-related quality of life is self-assessed via the KINDL® questionnaire. The KINDL® is a generic instrument for assessing health-related quality of life in children and adolescents. The KINDL® is a short, methodologically tested and flexible measurement instrument consisting of 24 questions on the six areas of body/physis, feelings/psychology, self-assessment, family, friends and school.
Time frame: Baseline, after 6 weeks, after 12 weeks
Physical Activity Health Literacy
Physical Activity Health Literacy Scale for Children (PAHL-C) evaluates children's self-reported knowledge and understanding of physical activity and its benefits through an 8-question scale.
Time frame: Baseline, after 6 weeks, after 12 weeks
Nutritional Health Literacy
The Nutrition Health Literacy Scale for Children (NHL-C) measures children's self-reported knowledge and understanding of nutrition and healthy eating using an 8-question scale.
Time frame: Baseline, after 6 weeks, after 12 weeks
Health-Related Quality of Life: Parent Version (Proxy-Report)
The KINDL® proxy-report assesses the child's health-related quality of life from the parent's perspective, using the KINDL® questionnaire designed for parents to provide insights on the child's health-related quality of life.
Time frame: Baseline, after 6 weeks, after 12 weeks
Health Literacy for Children
Health Literacy Survey Questionnaire for Children (HLS-Child-Q15) assesses children's ability to seek, evaluate, and use health information, including disease prevention and health promotion.
Time frame: Baseline, after 6 weeks, after 12 weeks
Health Literacy for Adults
Health Literacy Questionnaire (HLS EU-Q16) measures general health literacy in adults, covering access, understanding, and application of health information across various health domains.
Time frame: Baseline, after 6 weeks, after 12 weeks
