Insights
Children with chronic conditions are more likely to experience mental illness, especially if they have better health functioning. This highlights the need for early screening and intervention to prevent physical-mental multimorbidity.
Area of Science:
- Pediatric Health
- Child Psychology
- Public Health
Background:
- Chronic conditions in children can impact their mental well-being.
- Understanding the interplay between physical and mental health in pediatric populations is crucial.
Purpose of the Study:
- To quantify the association between chronic conditions and mental illness in children.
- To investigate moderating factors like health functioning and mediating factors like family functioning.
- To explore the impact of chronic conditions on specific mental health outcomes such as anxiety and ADHD.
Main Methods:
- Secondary data analysis of the 2014 Ontario Child Health Study (OCHS) involving 6242 children aged 4-17.
- Assessment of chronic conditions using Statistics Canada standards and mental illness using the Emotional Behavioural Scales (EBS).
- Logistic regression and interaction models were used to analyze associations, moderation, and mediation effects.
Main Results:
- A chronic condition was associated with mood disorder (OR=2.25).
- Children with chronic conditions and better health functioning showed increased likelihood of any mental illness (29%), anxiety disorders (21%), and ADHD (21%).
- No association was found between chronic conditions and mental illness in children with poorer health functioning; family functioning did not mediate these associations.
Conclusions:
- Health functioning significantly moderates the association between chronic conditions and mental illness in children.
- Specific mental health conditions like anxiety disorders and ADHD are more prevalent in children with chronic conditions and better health functioning.
- Routine mental health screening and early interventions are recommended for children with chronic conditions, particularly those with better health functioning, to address physical-mental multimorbidity.
Objectives:
This study aimed to quantify associations between chronic conditions and mental illness; investigate potential moderating effects of child age, sex, health functioning, mental health service contact and household income on these associations; and explore the potential mediating effect of family functioning.
Methods:
This study conducted secondary data analyses on a sample of 6242 children aged 4-17 years from the 2014 Ontario Child Health Study (OCHS). Chronic conditions were assessed using a standard list of conditions developed by the Statistics Canada. Mental illness was assessed with the Emotional Behavioural Scales (EBS). The Health Utility Index Mark III measured health functioning. Logistic regression models quantified associations between chronic conditions and mental illness. Moderating effects were tested with product-term interactions in logit models and interpreted using average marginal effects. Mediating effects were explored using the product of coefficients method.
Results:
Having a chronic condition was associated with mood disorder (OR = 2.25 [95% CI: 1.36-3.74]). For children who have better health functioning, average marginal effects indicated that children with chronic conditions are 29% more likely to have any mental illness (p < 0.01), 21% more likely to have anxiety disorders (p < 0.05) and 21% more likely to have ADHD (p < 0.05) than children with no conditions. For children who have poorer health functioning, there was no association between chronic conditions and mental illnesses. Family functioning did not mediate any associations between chronic conditions and mental illness outcomes.
Conclusion:
The association between chronic conditions and mental illness in children is nuanced, with health functioning moderating this association for any mental illness, anxiety disorders and attention-deficit hyperactivity disorder specifically. Mental health screening programs should ensure children with chronic conditions who have better health functioning are routinely assessed and upstream interventions initiated early to reduce the incidence of physical-mental multimorbidity.
