Abstract:
Objective: To 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.
Methods: Injury-related death cases among residents aged 60 years old and above in Yuyao City from 2013 to 2022 were selected for epidemiological analyses. Mortality rates, standardized mortality rates, age-specific mortality rates, annual percentage change (APC), average annual percent change (AAPC), and chi-square trend values were calculated to analyze the epidemiological characteristics of deaths.
Results: The crude injury mortality rate among elderly people aged 60 years old and above in Yuyao City was 263.90/10
5, with a standardized mortality rate of 131.21/10
5. A statistically significant decreasing trend in standardized mortality was observed from 2013 to 2020 (APC =-3.17%,
P = 0.017). The standardized injury mortality rates for elderly males and females were 154.74/10
5 and 134.46/10
5, respectively. Among elderly females, the standardized injury mortality rate initially decreased and then increased (APC
2013—2020=-5.14%, APC
2021—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 suffocation all increased significantly with age (
χ2 for trend = 8315.40, 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).
Conclusion: From 2013 to 2022, the injury-related mortality burden among adults aged 60 years old and above in Yuyao City remained substantial,.primarily caused by accidental falls, motor vehicle traffic injuries, drowning, accidental suffocation, 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.
