Joinpoint regression analysis of injury tendency among students in Changning District, Shanghai in 2010-2017 / 公共卫生与预防医学

ABSTRACT

Objective To investigate the current situation and annual trend of injuries among primary and middle school students in Changning District, Shanghai, and to provide scientific evidence for decision-making of prevention and control. Methods The monitoring data of various types of injuries was collected from the “cause of class absence” system during the 2010-2017 school years. The Joinpoint regression analysis was used to estimate the annual percent change and average annual percent change, and to perform the trend test. Results During the 2010-2017 school years in Changning District, a total of 2,286 cases of injuries occurred among primary and middle school students, with an injury rate of about 0.70%. The top three prevalent injury types were falls, traffic accidents, and burn-related injury. The results of Joinpoint trend analysis indicated that the incidence of total injuries in Changning District was generally decreasing, which was mainly due to the effective control of injuries caused by falls, traffic accidents, and burns, and to the decreasing injury incidence among primary school students. Conclusion The overall situation of injuries among primary and middle school students in Changning District has improved significantly, but falls and traffic accidents are still important health threats. More attentions should be paid to certain groups, such as vocational and special education students.
