Insights
Mental illness is common in children with chronic physical conditions, with parent reports indicating higher prevalence than child self-reports. Child disability is a key factor for early mental health intervention.
Area of Science:
- Pediatric Health
- Child Psychology
- Chronic Illness Management
Background:
- Mental illness is a significant concern in children with chronic physical conditions.
- Understanding the prevalence and correlates of mental illness in this population is crucial for effective intervention.
Purpose of the Study:
- To estimate the six-month prevalence of mental illness in children with chronic physical illness (multimorbidity).
- To examine agreement between parent and child reports of mental illness.
- To identify factors associated with mental illness in these children.
Main Methods:
- A cohort of 263 children aged 2-16 years with physician-diagnosed chronic physical illness was recruited.
- Mental illness was assessed using the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID) for both parent and child reports.
- Logistic regression was used to identify factors associated with mental illness.
Main Results:
- The six-month prevalence of mental illness was 38% based on parent reports and 25% based on child self-reports.
- Parent-child agreement on mental illness diagnosis was low (κ=0.18).
- Factors associated with mental illness included older child age, male sex, higher household income, parental depression symptoms, and child disability.
Conclusions:
- Mental illness (multimorbidity) is common in children with chronic physical illnesses and occurs across various physical conditions.
- Child disability is a significant, potentially modifiable correlate of mental illness, suggesting its utility for routine assessment in pediatric settings.
- Early mental health interventions, informed by disability assessment, are recommended to reduce the incidence of mental illness in children with chronic physical conditions.
Objective:
The aim of this study was to estimate the six-month prevalence of mental illness in children with chronic physical illness (multimorbidity), examine agreement between parent and child reports of multimorbidity, and identify factors associated with child multimorbidity.
Method:
The sample included 263 children aged 2-16 years with a physician-diagnosed chronic physical illness recruited from the outpatient clinics at a pediatric hospital. Children were categorized by physical illness according to the International Statistical Classification of Diseases and Related Health Problems (ICD)-10. Parent and child-reported six-month mental illness was based on the Mini International Neuropsychiatric Interview for Children and Adolescents (MINI-KID).
Results:
Overall, 101 (38%) of children had a parent-reported mental illness; 29 (25%) children self-reported mental illness. There were no differences in prevalence across ICD-10 classifications. Parent-child agreement on the MINI-KID was low (κ = 0.18), ranging from κ = 0.24 for specific phobia to κ = 0.03 for attention-deficit hyperactivity. From logistic regression modeling (odds ratio [OR] and 95% confidence interval), factors associated with multimorbidity were: child age (OR = 1.16 [1.04, 1.31]), male (OR = 3.76 [1.54, 9.22]), ≥$90,000 household income (OR = 2.57 [1.08, 6.22]), parental symptoms of depression (OR = 1.09 [1.03, 1.14]), and child disability (OR = 1.21 [1.13, 1.30]). Similar results were obtained when modeling number of mental illnesses.
Conclusions:
Findings suggest that six-month multimorbidity is common and similar across different physical illnesses. Level of disability is a robust, potentially modifiable correlate of multimorbidity that can be assessed routinely by health professionals in the pediatric setting to initiate early mental health intervention to reduce the incidence of multimorbidity in children.
