ABSTRACT
Objective To analyze the mortality characteristics and trends and the cause-eliminated life expectancy of gastric cancer in Harbin City from 1987 to 2019. Methods Mortality data of residents with gastric cancer from 1987 to 2019 in Harbin was analyzed to describe the mortality characteristics and trends of gastric cancer. Abridged life table and cause-eliminated life table were applied to calculate life expectancy and cause-eliminated life expectancy. Average annual percentage change (AAPC) was calculated with Joinpoint 4.2 software to evaluate the trends of mortality and cause-eliminated life expectancy of gastric cancer. Results From 1987 to 2019, the crude mortality, ASMRC and ASMRW and the truncated rate (35-64) were 14.3/105, 10.9/105, 10.9/105, and 13.5/105, respectively. The ASMRC showed an obvious decreasing trend at an average annual rate of 2.9% from 1987 to 2019 (95%CI: -4.4%--1.4%). Significant decreasing trends were observed for males (AAPC=-3.0%, 95%CI: -4.4%--1.7%) and females (AAPC=-3.1%, 95%CI: -5.3%--0.9%). An obvious decreasing trend in the ASMRW was also observed. The truncated rate (35-64) showed a downward trend (AAPC=-2.8%, 95%CI: -3.1%--2.5%). The average life expectancy of residents from 1987 to 2019 in Harbin were 76.78 years (male: 74.41 years, female: 79.33 years). After eliminating the causes of death of gastric cancer, the life expectancy increased by 0.25 years (male: 0.31 years, female: 0.18 years). Significant decreasing trends were found in the proportion of gastric cancer in all malignant cancer cases (AAPC=-0.18%, 95%CI: -2.0%--1.7%). Conclusion The mortality of gastric cancer decreases gradually from 1987 to 2019 in Harbin. After eliminating the causes of death of gastric cancer, the life expectancy increases by 0.25 years. Therefore, prevention and control should be strengthened.
ABSTRACT
Objective @#To investigate the mortality of cardiovascular and cerebrovascular diseases and to examine the effects on life expectancy among residents in Yuhang District of Hangzhou City from 2010 to 2020, so as to provide insights into the management of cardiovascular and cerebrovascular diseases.@*Methods@#The mortality surveillance data of cardiovascular and cerebrovascular diseases of registered residents in Yuhang District from 2010 to 2020 were collected from Zhejiang All-cause Death Surveillance System. The crude mortality, standardized mortality, annual percent change ( APC ), Fulfillment index, life expectancy, cause-eliminated life expectancy and years of life lost, and the mortality of cardiovascular and cerebrovascular diseases and the impact on life expectancy were analyzed.@*Results@#A total of 21 761 deaths occurred due to cardiovascular and cerebrovascular diseases in Yuhang District from 2010 to 2020, and the annual average crude and standardized mortality rates of cardiovascular and cerebrovascular diseases were 206.14/105 and 129.62/105, respectively. The annual crude and standardized mortality of cardiovascular and cerebrovascular diseases both appeared a tendency towards a decline from 2010 to 2020, with APC of -3.63% and -5.45%, respectively ( P<0.05 ), and the Fulfillment index showed a tendency towards a reduction in residents at ages of 50 to 79 years ( P<0.05 ). The mean life expectancy and cause-eliminated life expectancy were 82.71 and 88.39 years in Yuhang District from 2010 to 2020, which both appeared a tendency towards a rise, both with APC of 0.50% ( P<0.05 ). The years of life lost were 5.02 to 6.47 years due to cardiovascular and cerebrovascular diseases, and the life loss rates were 6.00% to 7.73%.@*Conclusions@#The mortality of cardiovascular and cerebrovascular diseases appeared a tendency towards a decline decreased and the cause-eliminated life expectancy appeared a tendency towards a rise in Yuhang District from 2010 to 2020. Intensifying the management of cardiovascular and cerebrovascular diseases death may increase the life expectancy.
ABSTRACT
Objective To analyze the premature death rate and life expectancy caused by cancer, cardiovascular disease, chronic respiratory disease and diabetes and to provide the basis for the government to formulate residents' health promotion measures. Methods The data of deaths of permanent residents in Tongxiang in 2016 were derived from"Zhejiang Chronic Disease Surveillance Information System" . The mortality, premature death rate, years of potential life loss and life expectancy of four chronic diseases were descriptively analyzed. Results In 2016, a total of 5104 deaths were reported in Tongxiang, with a crude death rate of 738.77 / 100, 000 and a standardized mortality rate of 480.40 / 100, 000, 23.59％ were premature deaths. The mortality rate of the four types of chronic diseases was 8.44％ , malignant tumors, cardiovascular and cerebrovascular diseases, chronic respiratory diseases, diabetes were 5.68％, 2.06％, 0.65％ and 0.24％. Residents' life expectancy was 81.40 years, removal of cardiovascular and cerebrovascular diseases, cancer, chronic respiratory diseases, diabetes, the life expectancy increased 3.69, 2.78, 1.43 and 0.16 years, respectively. The four types of chronic diseases had a potential life-loss loss of 15, 239 person-years, with an average life-saving year of 4.25 years and a life-saving rate of 22.06 ‰. Mortality rate, premature death rate, years of potential loss of life, average life expectancy and longevity rate were higher in males than in females. Conclusion The probability of premature death of four types of chronic diseases in Tongxiang was 8.44％, and male residents were more likely to be affected.
ABSTRACT
Objective To explore the causes of death and life expectancy after elimination of main causes of disease in residents of Tianjin. Methods The death registry data of Tianjin residents in 2014 were collected and coded in“international classification of disease, 10th edition”. The crude death rate and life expectancy after elimination of main causes of disease were calculated, respectively. Results In 2014, the crude death rate in Tianjin residents was 70.708 per million, while in male and female were 78.728 and 62.637 per million respectively. The main cause of death in Tianjin residents was non-communicable disease. The top four death causes were heart disease, cancer, cerebrovascular disease and respiratory disease, accounting for 31.5%, 23.6%, 22.2% and 8.3% of the total death. The top four life expectancy lost diseases were heart disease, cerebrovascular disease, cancer and respiratory disease, with a 6.46 year, 3.28 year, 3.11 year and 1.25 year life increase respectively. Conclusion Non-communicable diseases are the major reason of death and life expectancy lost disease in Tianjin residents, which needs urgent effective intervention to control.
