MethodsBased on population and death data from 2008 to 2017, retrospective analysis was done on indexes for mortality, potential years of life lost, life expectancy, death expectancy and attribution of disease death and so on.

ResultsThe proportion of residents aged ≥65 years in Gaodong Community increased from 14.99% in 2008 to 22.59% in 2017.The average crude death rate was 810.06/10⁵, the average standardized death rate was 356.03/10⁵, the male crude death rate was higher than female (P < 0.05), the total and male crude death rates between 2013 and 2017 were both higher than the rates between 2008-2012.(P < 0.05).The top five causes of death were circulatory system diseases, tumors, respiratory diseases, injuries and poisoning, endocrine, nutritional and metabolic diseases, which accounted for 80.11% of all death causes.The potential years of life lost (PYLL) for all-cause deaths were 8 662.00 person-years, the average years of life lost (AYLL) were 2.93 years per person, the PYLL rate was 23.73‰, the standardized potential years of life lost (SPYLL) was 8 053.26 person-years, the SPYLL rate was 22.06‰.The top death cause of PYLL was tumors and the top death cause of AYLL was injuries and poisoning.The average life expectancy from 2008 to 2017 was 83.34 years.Life expectancy could be increased by 5.27 and 4.11 years and the life growth rate could be increased by 6.32% and 4.93% respectively after eliminating the circulatory system diseases and tumors.The chronic diseases such as diabetes, heart diseases, cerebrovascular disease, colorectal cancer, respiratory diseases, esophageal cancer and hypertension were found to be negative attribution in the change of life expectancy from 2008 to 2017.
