  • Population-based cohort study
  • nationwide registry linkage

Authors' conclusion

More than one-third of children with CHD were diagnosed or treated for a mental health condition by 18 years of age. Mental health conditions began early in life and were most prominent among males and children with severe or single-ventricle heart disease.

Further findings

Incidence rates by age

Prominent peaks in early childhood and adolescence

Incidence rates by sex and CHD complexity (CHD cohort)

Higher in males vs females and in severe or single-ventricle CHD vs mild or moderate CHD

Specific conditions vs general population and siblings

Incidence rates and adjusted hazard ratios (aHRs) highest for severe stress reactions, ADHD, intellectual disability and autism spectrum disorder
aHRs close to 1 vs major congenital anomaly cohort
