Temporal trend of pediatric fracture epidemiology in Thailand: a nationwide study 2018–2024

Osteoporos IntPublished Retrospective nationwide claims-database study

Authors' conclusion

Fracture incidence among the Thai pediatric population was lower than that reported from Western countries and remained relatively constant during 2018-2024. Incidence was highest in male adolescents, with traffic accident being the major contributor. Strengthening targeted prevention, particularly traffic-safety interventions, should be a national priority to reduce pediatric fracture burden in Thailand.
