Insights

Children with intellectual disability (ID) and maltreatment face the highest health service use. Intellectual disability was the main factor linked to increased health burdens, especially mental health needs.

Area of Science:

  • Child Health
  • Public Health
  • Developmental Disabilities

Background:

  • Children with intellectual disability (ID) face significant social and health challenges.
  • Limited population-level data exists integrating child protection and healthcare information for this group.

Purpose of the Study:

  • To introduce the PROTECT databank, a linked administrative data resource in Québec, Canada.
  • To examine the cumulative burden of health service use in children with ID and/or maltreatment.

Main Methods:

  • A retrospective longitudinal cohort study of 18,095 children born between 2001-2016.
  • Linked data from child protection, physician billing, and hospitalization records.
  • Compared four cohorts: ID only, maltreatment only, both, or neither.

Main Results:

  • Children with co-occurring ID and maltreatment had the highest cumulative service use.
  • Intellectual disability was the primary correlate of elevated service use across all outcomes.
  • The highest mental health service burden was observed in children with both ID and maltreatment.

Conclusions:

  • The PROTECT databank is a valuable resource for studying developmental and protection risks.
  • Findings highlight significant health inequities for children with ID and maltreatment.
  • Actionable evidence is provided to reduce health disparities for vulnerable children.
