Characteristics of injury deaths and potential years of life lost in Huangpu district, Shanghai, 1993−2021

Objective  To analyze the characteristics and potential years of life loss of injury mortality in residents in Huangpu district of Shanghai, provide evidence for the prevention and control of injury in local residents.

Methods The mortality data of injury in local population from 1993 to 2021 were collected from Shanghai Death Cause Registration System. The crude mortality, standardized mortality, potential years of life lost (PYLL), average years of life lost (AYLL), annual percentage change (APC) and average annual percentage change (AAPC) were calculated.

Results The crude mortality of injury was 38.35/100 000, the standardized mortality rate was 31.26/100000, and the proportion of injury death in all death causes was 4.14%. The crude mortality rate or the proportion of injury deaths in all death causes were lower in men (36.97/100000, 3.86%) than in women (39.78/100000, 4.44%). The standardized mortality rate was higher in men (31.58/100000) than in women (30.85/100 000). The overall standardized mortality showed downward trend from 1993 to 2021, the AAPC was −3.41% 95% confidence interval (CI): −4.13 to −2.76, P<0.05 and the APC was −5.23% from 1993 to 2012 (95%CI: −6.93 to −4.37, P<0.01). The main death causes were falls (11.05/100 000), road traffic accident (5.26/100 000), suicide (4.09/100 000) and unintentional poisoning (1.84/100 000). The mortality rate was significantly higher in the elderly aged over 65 years (145.42/100 000) than in other age groups. The PYLL was 89518 person years, the AYLL was 8.22 years and the PYLLR was 3.21‰. The PYLL (60 328 person years), AYLL (11.46 years) or PYLL rate (PYLLR) (4.35‰) were higher in men than in women (29 191 person years, 5.19 years, 2.08‰). The top three injury death of PYLL and PYLLR were road traffic accident, suicide and unintentional poisoning.

Conclusion The injury mortality rate in residents in Huangpu showed an overall downward trend from 1993 to 2021. Falls, road traffic accident, suicide and unintentional poisoning were main causes of injury death. More attention should be paid to elderly people. It is necessary to establish a comprehensive injury surveillance system based on hospital and community to understand the epidemiological characteristics and trend of injury death and effectively prevent and control the incidence or death of injury.
