The trend of injury mortality rates among Chinese residents from 2004 to 2021
Objective It could provide evidence for the formulation of injury prevention and control strategies by analyzing the trend of the injury mortality rate of Chinese residents from 2004 to 2021.Methods The injury data on age,gender and urban-rural status were extracted from the《National Cause of Death Surveillance Dataset》from 2004 to 2021.The Joinpoint regression model was used to calculate the annual percent change(APC)and average annual percent change(AAPC).Results The injury standardized mortality rate of Chinese residents decreased from 2004 to 2021(AAPC=-4.43%,P<0.001).The AAPC was 1.12%for non-accidental falls(P<0.001).In contrast,the remaining four injury types showed a decreasing trend,corresponding to the AAPC was-5.44%,-4.16%,-5.87%and-3.24%respectively(P<0.001).From age perspective,drowning,road traffic accidents,and non-accidental falls were the main causes of injury in the 0-<15 years,15-<65 years,and ≥65 years sub-groups,respectively.Contrary,the ≥65 years age group showed an increasing trend for non-accidental falls(AAPC=1.82%,P=0.033).From different populations perspective,the injury standardized mor-tality rate of road traffic accidents was higher in males than females.And the injury standardized mortality rate in rural areas was higher than in urban areas each year,among them,males in rural were the highest group.Conclusions The injury mortality rate showed a decreasing trend from 2004 to 2021 for Chinese residents.For injury prevention and control,targeted intervention measures should be taken for males,the≥65 years age and rural residents as a focus group.
