Characteristics and trend of injury mortality in residents in Yantai, Shandong, 2012–2021

  Objective  To analyze the distribution and incidence trend of injury mortality in residents in Yantai, and provide evidence for injury prevention and control in this area.

  Methods  The surveillance data of injury deaths of residents in Yantai from 2012 to 2021 were collected. Excel 2019 and software SPSS 22.0 were used to calculate the crude mortality rate, standardized mortality rate of injury. The annual percent change (APC) and average annual percent change (AAPC) of the injury mortality rate and the standardized mortality rate were calculated by using Joinpoint regression model, and the trends were also examined.

  Results  From 2012 to 2021, the crude mortality rate of injury in residents in Yantai was 53.02/100 000, and the standardized mortality rate was 35.48/100 000 with a downward trend with year (AAPC=−5.45%, P<0.001). The crude mortality rate of injury in men was 73.54/100 000, and the standardized mortality rate was 51.79/100 000 with a downward trend with year (AAPC=−6.67%, P<0.001). The top three causes of injury death in men were road traffic accident, fall and suicide. The crude mortality rate of injury in women was 31.86/100 000, and the standardized mortality rate was 18.78/100 000 with a downward trend with year (AAPC=−4.78%, P<0.001). The top three causes of injury death in women were road traffic accident, suicide, and fall. The crude mortality rate of injury in children and adolescents aged 0−14 years was 8.23/100 000, and the standardized mortality rate was 8.20/100 000 with a downward trend with year (AAPC=−8.79%, P<0.01). The top three causes of injury death in children and adolescents were road traffic accident, drowning and other unintentional injuries. The crude mortality rate of injury in residents aged 15−64 years was 43.45/100 000, and the standardized mortality rate was 35.13/100 000 with a downward trend with year (AAPC=−7.50%, P<0.001). The top three causes of injury death in residents aged 15−64 years were road traffic accident, suicide, and other unintentional injuries. The crude mortality rate of injury in residents aged ≥65 years was 137.27/100 000, and the standardized mortality rate was 126.86/100 000. There was no statistical difference in injury mortality rate over the years (AAPC=−1.98%, P>0.05). The top three causes of injury death in residents aged ≥65 years were road traffic accident, fall, and suicide.

  Conclusion  From 2012 to 2021, the mortality rate of injury in residents in Yantai showed a downward trend. The mortality rate of injury in men was higher than that in women. Road traffic accident was the first cause of injury death. There were different distribution characteristics of injury deaths among people with different age. Therefore, it is necessary to take targeted prevention, control strategies and measures.
