Analysis of mortality status and cause-eliminated life expectancy by region in China
Objective To explore the current status of population mortality in different regions and study the changing trends of various causes of death,providing reliable evidence for the rational utilization of health resources.Methods Compared the rank order of death causes in the eastern,cen-tral,and western regions in 2010,2015,and 2020,compiled life expectancy tables and cause-eliminated life expectancy tables.Calculated mortality rate,standardized mortality rate,years of potential life lost rate and the seventh national population census data were used for standardization.Results The mortality rate in all regions showed a decreasing trend,and the standardized rate of mortality of western was the highest.The average annual increase in life expectancy was 0.32,0.34 and 0.31 years.Cancer,cerebrovascular disease,heart disease,respiratory disease and injury were the top five causes of death.in each region.Cancer was the leading cause of death in the eastern region,while the cerebrovascular disease is the leading cause in the central region.The rate of life lost due to heart disease showed an increasing trend in all regions,with the central region recording a heart disease of 49.50%in the age group above 85 in 2020.The rate of life lost due to respiratory system decreased annually,but showed an increasing trend with age and had the greatest impact on the lifespan in the western regions.The rate of life lost due to injuries showed an increasing trend in the age group above 75 years.Conclusions Life expectancy increased gradually in all regions,but the rate of life lost due to cardiovascular diseases continued to rise,and injuries also had an increasing impact on the lifespan of the elderly.Different diseases had varying impacts on the lifespan in different regions,and disease prevention and control strategies should be tailored to different ages and regions.
