Children with Congenital Heart Disease Show Increased Behavioral Problems Compared to Healthy Peers: A Systematic Review and Meta-Analysis.

ABSTRACT

Millions of children and adults are living with congenital heart disease (CHD). Their risk for behavioral problems has not been the subject of a meta-analysis. We performed a systematic review and meta-analysis of measures of behavioral problems in people born with CHD compared to peers without CHD. We searched Pubmed, CINAHL, Embase, PsycInfo, and the Cochrane Library from January 1, 1986 to November 15, 2021. We included studies that reported a measure of behavioral problems in patients with CHD in children and adults older than 3 years of age. We screened 26,343 search results, and 24 studies met inclusion criteria. The quality of evidence was generally low. Subjects with CHD had a small increase in internalizing problems [standardized mean difference (SMD) 0.198, p = 0.02] and total behavior problems (SMD 0.287, p = 0.013), but no difference in externalizing behavioral problems. There was significant heterogeneity in all three domains of behavior problems analyzed, and it could not be explained by variables such as age, severity, assessor, or assessment tool. There are small increases in parent- and self-reported overall behavioral problems and internalizing problems in patients with CHD compared to healthy controls. Wide confidence intervals in the meta-analyses leave open the possibility that certain factors may increase the risk of behavioral problems in this group, and future studies with important attention paid to potential confounders may help identify risk factors.
