Annual trends in childhood fracture and injury in Beijing from 2010 to 2019.

Abstract

Objective: To analyze the 10-year epidemiological trends of pediatric fracture and injuries in Beijing from 2010 to 2019.

Methods: This retrospective study included children presenting with fracture or injuries at the emergency department of Beijing Jishuitan Hospital (National Orthopedic Medical Center) during the study period. Demographic and clinical data (age, sex, seasonal distribution) were analyzed using linear regression.

Result: The number of fracture and injury in children increased (R = 0.856 and 0.828, P = 0.002 and 0.003); The mean age of children with fracture and injury increased (R = 0.946 and 0.744, p = 0.000 and 0.009). The number of fracture increased in the 6 ~ 8 years old, 9 ~ 11 years old and 12 ~ 14 years old age group (R = 0.748, 0.986 and 0.874, p = 0.013, 0.000 and 0.001). The number of injury in the 9 ~ 11 years old and 12 ~ 14 years old age group increased (R = 0.914 and 0.762, p = 0.000 and 0.010). The number of fracture in boys and girls increased (R = 0.806 and 0.912, p = 0.005 and 0.000). The number of injury in boys and girls increased (R = 0.646 and 0.935, p = 0.044 and 0.000). The number of fracture in spring and winter increased (R = 0.844 and 0.932, p = 0.002 and 0.000). The number of injury in spring, autumn and winter increased (R = 0.851, 0.701 and 0.918, p = 0.002, 0.024 and 0.000).

Conclusion: Beijing children experienced progressively rising fracture and injury rates during the study decade, with notable increases in older age groups. The proportional rise of fracture among injured children suggests changing injury patterns. While seasonal and gender differences persist, their relative impact appears to be diminishing over time.
