Each year an estimated 328,500 infants age 0-12 months are treated for unintentional injuries in emergency departments (EDs): one infant every minute and a half. The leading cause, overall and by month of age, was fall-related injury. The second leading cause was 'struck by or against.' The majority of patients were injured at home. Younger infants were more likely to be hospitalized than older ones and more males than females were injured. Gender differences suggest that parenting practices may play a role, but ecological approaches should be considered in an effort to understand the connection between injuries and an infant's developmental stage.  相似文献
