Mental health service contact in children with and without physical-mental multimorbidity.

Abstract

Purpose: To estimate six-month prevalence of child mental health service contacts and quantify associations between child health status and mental health service contacts, including number of types of contacts.

Methods: Data come from 6,242 children aged 4-17 years in the Ontario Child Health Study. A list of chronic conditions developed by Statistics Canada measured physical illness. The Emotional Behavioural Scales assessed mental illness. Child health status was categorized as healthy, physical illness only, mental illness only, and multimorbid (≥ 1 physical and ≥ 1 mental illness). Mental health service contact was aggregated to general medicine, urgent medicine, specialized mental health, school-based, alternative, and any contact (≥ 1 of the aforementioned contacts). Regression models quantified associations between health status and type of mental health contact, including number of types of contacts.

Results: Weighted prevalence estimates showed 261,739 (21.4%) children had mental health-related service contact, with school-based services being the most common contact amongst all children, regardless of health status. Children with multimorbidity had higher odds for every mental health contact than healthy controls (OR range: 4.00-6.70). A dose-response was observed, such that the number of contacts increased from physical illness only (OR = 1.49, CI: 1.10-1.99) to mental illness only (OR = 3.39, CI: 2.59-4.44) to multimorbidity (OR = 4.13, CI: 2.78-6.15).

Conclusion: Over one-fifth of children had mental health-related service contact and contacts were highest among children with multimorbidity. Types of mental health contacts for children with multimorbidity are diverse, with further research needed to elucidate the barriers and facilitators of mental health use.
