Characteristics and trend analysis of injury causes of death in Qingpu District of Shanghai，2002‒2020

Abstract

ObjectiveTo analyze the characteristics and changing trend of injury cause of mortality of residents in Qingpu District from 2002 to 2020， and to provide scientific reference for formulating regional prevention and control measures.MethodsThe injury mortality data of the registered residents in Qingpu District from 2002 to 2020 were collected. The indicators such as crude mortality rate， standardized mortality rate， and the ranking of causes of death were calculated.ResultsFrom 2002 to 2020， the average annual crude mortality rate was 50.27/ 100 000， the age-standardized mortality rate based on the world standard population（ASRW） was 30.08/100 000， and the age-standardized mortality rate based on the 2010 Chinese census（ASMRC） was 35.58/100 000. The average annual crude mortality rate of males was higher than that of females ［Z=54.402， Mantel-Hanszel χ2=1 742.509， P<0.01）. The overall injury mortality rate showed a downward trend with an average annual percent change（AAPC）of -4.07% （95%CI： -5.23%‒-2.90%）， P<0.001］. The top four causes of injury death were transportation accident， indeliberate fall， drowning， and suicide. The leading causes of death in 0‒ years old， 15‒ years old and ≥65 years old were drowning， transportation accident and indeliberate fall， respectively. The ASRW of transportation accident， drowning and suicide all showed a decreasing trend， and the AAPC were -8.22% （95%CI： -10.16%‒-6.24%）， -6.99% （95%CI： -9.68%‒-4.22%） and -6.21% （95%CI： -9.38%‒-2.94%）， respectively.ConclusionThe injury death rate of residents in Qingpu District shows a decreasing trend， and the distribution characteristics of injury death are different among different genders and age groups. Corresponding prevention and control strategies should be adopted for different populations.
