RESUMO
Objective@#To compare injuries prevalence among elementary and high school students in Beijing in the year of 2012 and 2017, and to provide a scientific basis for formulating the policies and measures on injuries prevention and control for the students in Beijing.@*Methods@#A multi-stage sectional random group sampling method had been used in the two surveys to sample from elementary and high school students in 16 districts of Beijing, and a retrospective questionnaire survey was conducted to investigate the injury occurrence during the past year, injury incidence in the year of 2012 and 2017 was compared.@*Results@#The incidence of injuries was 10.68% among elementary and high school students in 2016-2017 year period, which was lower than that in 2011-2012 year period(12.87%)(χ2=41.65，P<0.01). In 2016-2017 year period, the incidence of injuries for boys was 12.98%, and for girls was 8.63%, which were all lower than that in 2011-2012 year period(15.64% and 10.19%)(χ2=25.09, 13.57, P<0.01). Among all types of injuries, the incidence of falls was the highest in the two academic years. The incidence of falls in elementary and high school students in 2016-2017 year period was 6.35%, which was lower than that in 2011-2012 year period(7.36%)(χ2=14.68, P<0.01). The number of the injury cases being occurred in schools was at the top in the two academic years. The incidence rate of school injuries among students in 2016-2017 year period was 4.60%, which was lower than that in 2011-2012 year period (5.36%)(χ2=11.02, P<0.01). The incidence rates of unintentional injury, self-injury as well as intentional injury from otherrs in elementary and high school students in 2016-2017 year period were all lower than the rates in 2011-2012 year period(χ2=25.58, 10.05, 16.14, P<0.01).@*Conclusion@#After adopting a series of strategies and measures, student injuries decreased indicating that these measures are effective. In the future,more effective methods for student injury prevention should be developed to prevent and control the occurrence of the injuries for students.
