Abstract:
ObjectiveTo analyze the causes and trends of injury-related mortality among elderly residents in Yuyao City, and to provide a scientific basis for formulating prevention and control strategies for injury-related deaths among the elderly. MethodsData on injury-related deaths among elderly residents aged 60 years old and above in Yuyao City from 2013 to 2022 were collected. The epidemiological characteristics were analyzed, including the crude mortality rates, standardized mortality rates, age-specific mortality rates, annual percent change (APC), and average annual percent change (AAPC). ResultsThe crude mortality rate of injury among elderly people aged 60 years old and above in Yuyao City was 263.90/100 000, with a standardized mortality rate of 131.21/100 000. A statistically significant decreasing trend in standardized mortality was observed from 2013 to 2020 (APC=-3.17%, P=0.017). The standardized mortality rates of injury for elderly males and females were 154.74/100 000 and 134.46/100 000, respectively. Among elderly females, the standardized mortality rate of injury initially decreased and then increased (APC2013—2020=-5.14%, APC2021—2022=22.86%, both P<0.05). The top five causes for injury-related deaths among the elderly were accidental falls, traffic injuries from motor vehicles, drowning, accidental asphyxia, and suicide, accounting for 74.78% of all injury-related deaths among the elderly. Among these top five causes, mortality rates due to accidental falls, motor vehicle traffic injuries, and accidental asphyxia all increased significantly with age (χtrend2=8 315.40, 25.12, and 37.26, respectively; all P<0.001). Analyses of the annual trends showed a significant increase in deaths caused by accidental falls (AAPC=4.97%, P=0.013) and a significant decrease in deaths caused by suicide (AAPC=-14.87%, P<0.001). ConclusionFrom 2013 to 2022, the injury-related mortality burden among adults aged 60 years old and above in Yuyao City remained considerable, primarily caused by accidental falls, motor vehicle traffic injuries, drowning, accidental asphyxia, and suicide. There is an urgent need to develop targeted injury prevention strategies and measures to reduce the risk of unintentional injury deaths among the elderly.
