Physical activity assessments in children with congenital heart disease: A systematic review

Aim: To describe the physical activity (PA) of children with congenital heart disease (CHD) according to different assessment methods and compare their results with the World Health Organization (WHO) recommendations. Methods: A systematic review was conducted using five databases. We included cross-sectional, longitudinal, observational studies and clinical trials in a paediatric population with CHD. In publications with indirect measurement, the score in each dimension was considered. Similarly, moderate-to-vigorous PA (MVPA) was considered as the main outcome in articles with direct measurement. Results: A total of 1103 articles were found, and 16 primary articles were considered. Eight articles evaluated PA with indirect methods, six with direct methods and two used both methods, representing 1649 subjects evaluated. It was found that 46% of children with CHD do not exceed WHO recommendations for MVPA, with no differences depending on the severity of CHD. Conclusion: There are a variety of ways to measure PA in children with CHD. In the articles that objectively evaluated PA, the most measured outcome was the MVPA, which shows that the MVPA time was shorter in about half of the children with CHD than what is recommended by WHO.
