Epidemiological characteristics of injury-induced deaths among the residents in Taizhou City, Zhejiang Province, 2009‒2022

ObjectiveTo analyze the mortality rate and the changing trends of injury in Taizhou City from 2009 to 2022, so as to provide a reference for developing injury intervention strategies.MethodsSurveillance data on injury deaths of the registered residents in Taizhou from 2009 to 2022 were used, and descriptive statistics and χ2 test were employed to analyze the mortality rates and differences by age group, gender, and region. Joinpoint regression analysis was used to analyze the trends and calculate the annual percentage change(APC).ResultsFrom 2009 to 2022, a total of 53 707 injury deaths were recorded in Taizhou, with a mortality rate of 64.38/105 and a standardized mortality rate of 66.68/105. The injury mortality rate showed a decreasing trend (APC=-1.30%, P<0.05). The top five causes of death were accidental falls, traffic accidents, drowning, suicide, and accidental poisoning, all showing a decreasing trend (APC=-3.30%, -7.65%, -2.77%, -5.78%, and -7.82%, respectively, all P <0.05). The leading causes of death for those under 15 years old, 15‒64 years old, and 65 years old and above were drowning, traffic accidents, and accidental falls, respectively. There was no statistical difference in the mortality rate between urban and rural areas (χ2=3.81, P=0.05), but there was a statistical difference between genders (χ2=7 520.15, P<0.01).ConclusionIn recent years, injury deaths among the residents in Taizhou have been decreasing. Efforts should be made to strengthen the prevention and control of injuries such as drowning in children, traffic accidents in middle-aged and young people, and accidental falls in the elderly.
