What this trial studies

This study aims to develop and evaluate a 12-week digital lifestyle intervention designed for children aged 8-13 with congenital heart disease and their guardians. Participants will use a Garmin Vivofit Jr. 2 wearable device to monitor their physical activity levels continuously. The intervention focuses on increasing moderate to vigorous physical activity, improving daily activity, enhancing quality of life, and boosting health literacy for both children and their parents. The study will assess the effectiveness of this digital approach in promoting healthier lifestyles among affected families.

Why it matters

Potential benefit: If successful, this intervention could significantly improve physical activity levels and overall quality of life for children with congenital heart disease and their guardians.

How similar studies have gone: While digital interventions for promoting physical activity in children with congenital heart disease are limited, similar approaches in other pediatric populations have shown promise.
