Background: Children and adolescents operated upon for congenital heart disease (ConHD) may show reduced exercise capacity and physical activity, possibly associated with lowered self-esteem and quality of life (QoL). The studies into associations between these parameters have not been reviewed before.
Objective: Review of studies into associations between exercise capacity, physical activity, respectively exercise training, and psychosocial functioning of ConHD youngsters.
Data sources: PubMed, Embase and reference lists of related articles.
Study selection: Articles published between January 2000 and December 2012 into exercise capacity and/or physical activity, and a measure of psychosocial functioning in children with ConHD.
Data extraction: Two investigators independently reviewed the identified articles for eligibility, and one author extracted the data.
Results: Although exercise capacity was strongly related to physical domains of parent-reported and self-reported QoL, it was almost never associated with psychosocial domains of QoL. Physical activity was rarely associated with physical or psychosocial domains of QoL. Remarkably, self-reported depressive symptoms were associated with both physical and psychosocial QoL. The few studies into exercise-training programmes showed promising results in QoL and emotional and behavioral problems, but they contained methodological flaws.
Conclusions: No clear relationships were found between exercise capacity, physical activity, and QoL in children and adolescents with ConHD. Therefore we recommend assessing QoL separately, preferably both self-reported and parent-reported. Since depressive symptoms were associated with reduced physical and psychosocial QoL, screening on these symptoms is also recommended.
