Insights
Physical activity in children after the Fontan procedure is linked to factors like medication, outdoor time, and family income, not just heart health. Interventions targeting these areas can help children meet recommended activity levels.
Area of Science:
- Pediatric Cardiology
- Exercise Physiology
- Child Health
Background:
- Children with complex heart defects often exhibit sedentary behavior, irrespective of their exercise capacity.
- The Fontan procedure is a palliative surgery for complex single-ventricle congenital heart disease.
Purpose of the Study:
- To identify factors associated with the physical activity levels of children who have undergone the Fontan procedure.
- To understand the relationship between physical activity and various health and environmental factors in this population.
Main Methods:
- A cross-sectional study involving 64 children (aged 5-11 years) post-Fontan procedure.
- Measurements included moderate-to-vigorous physical activity (MVPA), cardiac status, cardiopulmonary capacity, motor skills, body composition, and perceived activity levels.
Main Results:
- Children achieved 361 ± 137 minutes/week of MVPA.
- Increased activity correlated with antithrombotic medication, lower resting heart rate, more outdoor time, lower family income, and higher parent-rated activity.
- Decreased activity was associated with winter season, history of arrhythmia, and higher child self-efficacy for activity.
Conclusions:
- Physical activity post-Fontan procedure is influenced by non-cardiac factors.
- Interventions addressing modifiable factors like medication, environment, and psychological confidence may improve activity levels.
- Achieving recommended activity levels is crucial for optimal health in these children.
Background:
Children with complex heart defects are sedentary, with activity level unrelated to exercise capacity. We sought to identify factors associated with physical activity level for children who have the Fontan procedure.
Methods:
We used a cross-sectional study, 64 children (25 female, 5-11 years) after Fontan. Measurements were weekly minutes of moderate-to-vigorous physical activity, cardiac status, resting/exercise cardiopulmonary capacity, gross motor skill, health-related endurance/strength/body composition, and parent/child activity perceptions.
Results:
Participants performed 361 ± 137 minutes per week of moderate-to-vigorous physical activity. Increased activity related to antithrombotic medication use (86 min/wk), lower resting heart rate (3 min/wk), higher weekday outdoor time (0.7 minutes per outside minute), lower family income (13 minutes per $10,000), and higher parent rating of child's activity relative to peers (36 min/wk). Factors related to decreased activity were winter season (-84 min/wk), history of arrhythmia (-96 min/wk), and greater child confidence in own ability to be active (-113 min/wk).
Conclusions:
Physical activity after the Fontan procedure is primarily associated with factors unrelated to cardiac status. Interventions that impact these modifiable factors would be expected to enable these children to achieve the recommended activity levels associated with optimal health.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
