title: The Association Between Hospital-Treated Injuries and ADHD Symptoms in Childhood and Adolescence: A Follow-Up Study in the Northern Finland Birth Cohort 1986.
abstract: OBJECTIVE
  We examined the risk of hospital-treated injuries related to the symptoms/diagnosis of ADHD.
  
  
  METHODS
  The study population (N = 6,111) was composed from the Northern Finland Birth Cohort 1986. At the age of 8, symptoms of hyperactivity and at the age of 15, symptoms of ADHD were assessed by the parents while the clinical diagnoses of ADHD were set in adolescence. Information on injuries was obtained from national register.
  
  
  RESULTS
  The risk for hospital-treated injuries during ages 0 to 7 was 1.7-fold increased among those with symptoms of hyperactivity assessed at age 8. Also, injuries during ages 7 to 15 years were more common among those with symptoms of ADHD at age 15 with respect to any injury, fractures, and intracranial injuries, and among those with the diagnosis of ADHD with respect to any injury.
  
  
  CONCLUSIONS
  The present study shows an association between hospital-treated injuries and symptoms of ADHD in a large epidemiological sample of 0- to 15-year-old children.
