title: Examination of the Comorbidity of Mental Illness and Somatic Conditions in Hospitalized Children in the United States Using the Kids' Inpatient Database, 2009.
abstract: OBJECTIVE
  To examine the associations between mental and physical illness in hospitalized children.
  
  
  METHODS
  The data for this analysis came from the 2009 Kids' Inpatient Database (KID). Any child with an International Classification of Diseases, Ninth Revision code indicative of depressive, anxiety, or bipolar disorders or a diagnosis of sickle cell disease, diabetes mellitus type 1 or 2, asthma, or attention-deficit/hyperactivity disorder (ADHD) were included. Using SAS software, we performed χ(2) tests and multivariable logistic regression to determine degrees of association.
  
  
  RESULTS
  Children discharged with sickle cell disease, asthma, diabetes mellitus type 1, diabetes mellitus type 2, and ADHD were 0.94, 2.76, 3.50, 6.37, and 38.39 times more likely to have a comorbid anxiety, depression, or bipolar disorder diagnosis than other hospitalized children, respectively.
  
  
  CONCLUSIONS
  Children with several chronic physical illnesses (asthma, diabetes mellitus type 1, diabetes mellitus type 2) and mental illnesses (ADHD) have higher odds of being discharged from the hospital with a comorbid mood or anxiety disorder compared with other children discharged from the hospital. It is therefore important to screen children hospitalized with chronic medical conditions for comorbid mental illness to ensure optimal clinical care, to improve overall health and long-term outcomes for these children.
