Do Attention Deficit/Hyperactivity Disorder and Oppositional Defiant Disorder Influence Preschool Unintentional Injury Risk?

PurposeThis study explores the relationship among preschool attention deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), injury-risk-taking behavior, and unintentional injury.MethodAn emergency department (ED) casecontrol study of parent-reported child behavior was conducted.FindingsChildren with ODD and ADHD had significantly more injury-risk-taking behaviors (odds ratio [OR] = 7.68, 95% confidence interval [CI] 2.25–26.25; OR = 4.87, 95% CI 1.17–-20.28, respectively), and injured children had a 17-fold increase in high-risk-taking behaviors (OR 17.2, 95% CI 2.14–-138.0). No significant association existed between ODD or ADHD and ED-treated unintentional injury.ImplicationsDisruptive behavior disorders are not major contributors to ED-treated unintentional injury in preschool children.
