The Relationship Between Physical and Mental Disorders in a Pediatric Population

Abstract

Introduction

Few studies examine comorbidity in a pediatric population. This poster presents results that extend our understanding of the relationship between mental disorder and physical disorders using a population-based study approach.

Objectives and aims

To review the evidence behind comorbidity of psychiatric disorders and other medical disorders. To propose an informatic approach that evaluates those comorbidity on a population-scale.

Methods

Using an informatics approach, a dataset containing physician billing data for 235,968 (51% male) individuals up to 18 years old spanning sixteen fiscal years (1994–2009) in Calgary, Alberta, was compiled permitting examination of the relationship between physical disorders and mental disorders, based on the International classification of diseases (ICD).

Results

All major classes of ICD physical disorders had odds ratios with confidence intervals above the value of 1.0, ranging from 1.08 (Perinatal Conditions in 4–6 year olds) to 4.95 (Respiratory Conditions in 0-3 year olds). Distinct major class ICD disorder patterns arise in comparing all children with adults and specific age strata for those under 19 years of age.

Conclusions

This study represents the first evidence reported in a population-based data set of the effect of mental disorders on each major class of ICD diagnoses related to a physical disorder. The focus on the early intertwinements between physical and mental disorders in a pediatric population may help to target strategic areas for future research and investment.
