Methods Data of student physical assault injuries came from the Dalian Hospital Injury Monitoring System from 2018 to 2022, descriptive epidemiological methods and Chi-square tests were used for statistical analysis. Results A total of 1 413 cases of physical assault injuries among students were reported, and the sex ratio between male and female was 4.12∶1. The number of reported physical assault injuries dropped from 414 cases in 2018 to 209 cases in 2022. The group of senior middle school/secondary vocational school had the highest proportion of cases (40.13%). Injuries occurred in all months, with the highest number of reported cases in June, October, and November, accounting for 33.97%. The main causes of injuries were blunt instrument injuries and falls, accounting for 70.06% and 23.35% respectively. The proportion of male (71.24%) was significantly higher than female (65.22%) in blunt instrument injuries (χ2=3.84, P < 0.05). Nearly 75.58% of injuries occurred during leisure time. The main locations of injuries took place in schools and roads, accounting for 51.52% and 23.35% respectively. Contusions and sharp instrument injuries were one of the most common types of injuries, accounting for 67.16% and 22.29% respectively. The main area of injury was concentrated in the head, accounting for 59.52%. Most of injuries were mild and moderate, accounting for 72.26% and 27.60%, respectively. Conclusions Schools are the main location for physical assault injuries among students, with boys and middle school students being the most vulnerable populations.
