Objective To understand the death level and distribution characteristics of death causes of registered residents in Tianfu New Area of Sichuan Province from 2020 to 2022,to analyze the impact of different diseases on life expectancy and potential life loss,and to provide scientific evidence for formulating relevant disease prevention and control policies in this region.Methods The monitoring data of death causes of registered residents in Tianfu New Area of Sichuan Province from 2020 to 2022 were collected.The mortality rate,standardized mortality rate,cause of death sequence,life expectancy,cause-deleted life expectancy,potential years of life lost(PYLL),potential years of life lost rate(PYLLR)and average years of life lost(AYLL)were calculated by Excel 2019 and SPSS 26.0.Chi-square test was used to compare the rates,and the test level was α=0.05.Results The crude mortality rate and standardized mortality rate of registered residents in Tianfu New Area of Sichuan Province from 2020 to 2022 were 450.57/105 and 379.95/105,respectively.The mortality rate of males was higher than that of females.The top five causes of death were malignant tumors,respiratory diseases,cerebrovascular diseases,heart diseases and injuries and poisonings,accounting for 85.58%of the total death causes.The average life expectancy was 82.79 years,with 80.29 years for males and 85.52 years for females,respectively.After eliminating the top five causes of death,the life expectancy increased by 3.45 years,3.32 years,2.20 years,1.46 years and 1.08 years,respectively.The diseases with the greatest impact on the life expectancy of men and women were malignant tumors and respiratory diseases,respectively.The PYLL caused by all death causes was 46 496 person-years,the AYLL was 4.42 years/person and the PYLLR was 19.92%o of residents of Tianfu New Area.The top five causes of life loss was malignant tumors,injuries and poisonings,cerebrovascular diseases,heart diseases and digestive system diseases,accounting for 77.45%of the total life loss of the residents.Conclusions Chronic noncommunicable diseases led by malignant tumors were the main factors affecting the health of residents in Tianfu New Area of Sichuan Province.Comprehensive prevention and control measures should be taken for major chronic diseases to improve the health level and life expectancy of residents.
