Although unintentional injury remains a major cause of morbidity and mortality among children, significant progress has been made toward reducing the burden of trauma over the past 30 years.1 An important factor in this success has been the application of an epidemiological approach to injury as a disease, most famously advanced by William Haddon, Jr.2 Epidemiologists studying the determinants and distribution of injury consider factors in the host (the child at risk for injury), the vehicles or vectors that cause injury, and the environments in which child injury occurs. Because injury risk and outcome are so often behaviorally determined, the salient “environment” in injury epidemiology includes both the physical context of injury and the child's sociocultural milieu.
