Analysis of injuries and poisoning deaths among residents in Changsha City from 2017 to 2021
Objective To analyze the characteristics of injuries and poisoning deaths and cause-eliminated life expectancy of the current residents in Changsha City from 2017 to 2021,and to provide a scientific basis for the formulation of prevention and control measures.Methods Descriptive statistics were used to analyze and compare the crude mortality rate,standardized mortality rate,average annual percent change(AAPC),cause-eliminated life expectancy indicators etcetera to evaluate deaths.The trend test was performed using two-sided t test,and the comparison between groups was performed using the x2 test.Results The average annual crude mortality rate and standardized mortality rate of injury and poisoning among current residents in Changsha City from 2107 to 2021 were 36.09/100 000 and 35.15/100 000,respectively.From 2017 to 2021,the crude mortality rate and standardized mortality rate of males were higher than those of females,and the differences were statistically significant(x2crude mortality rate=404.181,316.359,210.612,236.338,281.160,P<0.05;x2standardized mortality rate=388.137,296.101,195.096,222.768,223.019,P<0.05).The crude mortality rate and standardized mortality rate of injury and poisoning in the whole population in different years showed a downward trend(t=-5.691,-4.974,both P<0.05).The mortality rate was lowest among children aged 5-<15 years,and the mortality rate increased with age in people aged ≥5 years.After the causes of death of injury and poisoning were removed in 2021,the life expectancy of males increased by 0.94 years old and that of females increased by 0.57 years old.Conclusion Motor vehicle traffic accidents are the main sub-causes of injury and poisoning deaths in Changsha City,resulting in a greater loss of life expectancy.Different interventions should be taken to reduce the occurrence of deaths for different populations by targeting the sub-causes of deaths of motor vehicle traffic accidents,accidental falls,drowning,and suicide.
