Insights
Congenital heart disease (CHD) is linked to a small increase in internalizing and total behavioral problems in children and adults. Further research is needed to identify specific risk factors for these behavioral issues in the CHD population.
Area of Science:
- Cardiology
- Developmental Psychology
- Behavioral Science
Background:
- Congenital heart disease (CHD) affects millions globally, yet behavioral problem risks remain under-researched.
- A comprehensive meta-analysis was needed to synthesize existing evidence on behavioral issues in individuals with CHD.
Approach:
- A systematic review and meta-analysis was conducted, searching major databases (PubMed, CINAHL, Embase, PsycInfo, Cochrane Library) from 1986 to 2021.
- Included 24 studies assessing behavioral problems in individuals aged over 3 years with CHD compared to controls.
- Analyzed internalizing, externalizing, and total behavior problems using standardized mean differences (SMD).
Key Points:
- Individuals with CHD showed a small but significant increase in internalizing problems (SMD: 0.198) and total behavior problems (SMD: 0.287).
- No significant difference in externalizing behavioral problems was observed between groups.
- Significant heterogeneity was noted across studies, with no clear explanation from analyzed variables like age or CHD severity.
Conclusions:
- This meta-analysis indicates a heightened risk for internalizing and overall behavioral problems in individuals with CHD.
- The low quality of evidence and unexplained heterogeneity highlight the need for future research.
- Future studies should focus on identifying specific risk factors and controlling for potential confounders to better understand and manage behavioral health in the CHD population.
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.
