Objective：To investigate the epidemiological feature in non-hospitalized children with trauma，providing references to the science popularization，prevention and treatment. Methods：Electronic medical records of non-hospitalized children with trauma in Children's Hospital of Chongqing Medical University from August 2017 to July 2019 were retrospectively analyzed. Results：A total of 17 268 children were included，with gender ratio of 1.73∶1 and average age of （4.31±2.82） years old. Annual high prevalence time included April （1 777/17 268，10.29%），July（1 752/17 268，10.15%） and December（1 574/17 268，9.12%）. Daily high prevalence time was 18：00 to 19：59 （3 475/17 268，20.12%）. Common injury places contained homes（7 932/17 268，45.93%） and schools （5 526/17 268，32.00%）. Positions were easily injured were head （12 150/17 268，70.36%） and limbs（3 605/17 268，20.88%）. Head injuries were mostly caused by falling down（7 805/12 150，64.24%） and bump（3 657/12 150，30.10%），while limb injuries by sharp instruments（1 122/3 605，31.12%） and scald （1 342/3 605，37.23%）. Moreover，falling down to cause head injury was the initial in－jury cause（7 805/17 268，45.20%）. Conclusion：The characteristics of trauma in non-hospitalized children follows some rules. Strengthening health education for children and caregivers，ra－tional allocation of medical resources，home-school joint pre－vention of trauma，protection of head and limbs，and focusing on scald pretreatment and safety of activity places can effectively reduce the trauma.
