Pediatric fractures in northern China: hospital-based epidemiology and high-risk factors from a regional cohort study

Pediatric fractures in this regional cohort showed clear differences across sex, age, season, and time of injury. Younger children were mainly affected by fall-related injuries, whereas adolescents experienced more traffic- and activity-related trauma. These patterns suggest that prevention efforts should be tailored to developmental stages, such as improving home safety for preschoolers and reinforcing traffic and sports safety education for older children.
