Pediatric Academic Societies Apr 25 2026 At every age, children in the United States die at higher rates than peers in other high-income nations, according to a new study from Children's Hospital of Philadelphia. Findings from the study will be presented during the Pediatric Academic Societies (PAS) 2026 Meeting, taking place April 24-27 in Boston. The study found that the U.S. mortality disadvantage emerged as early as 1952 among older adolescents and has persisted for more than five decades.
