Background : The aim of the study was to analyse the incidence of school accidents in relation to school size, urban/rural environment and conditions of physical education classes. Methods : 202 primary schools with nearly 50,000 students aged 7-15 years were studied during a 6-year period in the Wloclawek region in Poland. Results : There were in total 3274 school accidents per 293,000 student-years. Accidents during breaks (36.6%) and physical education (33.2%) were most common. Most frequently accidents took place at schoolyard (29.7%), gymnasium (20.2%), and in the corridor and stairs (25.2%). After adjustment for students'age and sex, student-staff ratio and duration of school hours, urban environment increased the probability of accident (OR : 1.25 ; 95% CI : 1.14 1.38). Middle-size schools (8-23 classes) had similar accident rate as small schools (OR : 0.93 ; 95% CI : 0.83-1.04), while schools with 24-32 classes (OR : 1.26 ; 95% CI : 1.10-1.43) and with>=33 classes (OR : 1.36 ; 95% CI : 1.17-1.58) had increased accident rate. Presence of a gymnasium was also associated with increased probability of accident (OR : 1.49 ; 95% CI : 1.38-1.61). Conclusions : Urban environment, larger school-size and equipment with full-size gymnasium are important and independent risk factors for school accidents. These findings provide some new insights into the epidemiology of school-related accidents and may be useful information for the planning of strategies to reduce accident incidence in schools.
