Abusive head trauma (AHT) is the third leading cause of all head injuries and the leading cause of trauma death among U.S. children aged <2 years. Pediatric AHT is defined as an injury to the skull or intracranial contents of an infant or young child (aged <5 years) due to inflicted blunt impact and/or violent shaking.1 In 2003, the estimated national AHT incidence rate among children aged <2 years was 32 cases per 100,000 person-years.2 The purpose of this study was to characterize the Alaska-specific epidemiology of pediatric AHT among children aged <2 years. Because existing individual public health databases are limited in their ability to detect AHT cases, we used the Alaska Surveillance of Child Abuse and Neglect (SCAN) data system, which links together multiple public health databases. Methods AHT cases among children aged <2 years residing in Alaska during 2005–2010 were identified in each SCAN source and subsequently linked together to identify unique cases. The SCAN data sources included vital death records, the Violen
