| ObjectiveTo understand the death characteristics,causes of death and trends in the six years of residents of Mengzi City,Yunnan Province in 2012-2017,and to identify the major diseases threatening the health of residents in mengzi city at this stage,so as to provide scientific basis for determining health priority to solve problems and formulating disease prevention and control strategies.MethodThe data of death cause monitoring of household registration residents in Mengzi City,Yunnan Province from 2012 to 2017 was collected from the “Death Registration Report Information System”.The underlying causes of disease are classified and coded according to the International Classification Standard(ICD-10).The data was summarized,organized and analyzed using the Death Cause Registration Report(DeathReg2005),Excel 2016,and SPSS 24.0 statistical software.The usage rate and composition ratio of counting data indicate that the frequency of death is used to describe the frequency of death.The composition ratio is used to describe the composition of death causes.The comparison between the counting data groups is based on the ?2 test,and the trend analysis is based on the chi-square linear trend test.The test level is ?=0.05.Use the abbreviated current life table and the death cause life table to calculate the average life expectancy and the destiny life expectancy after removing different diseases.The mortality rate was standardized using the population of the sixth national census in 2010.The number of years of life lost was calculated at the age of 69.Result(1)In 2012-2017,the monitoring of death causes in Mengzi City covered2,454,562,and the male-female ratio was 1.07:1.The burden factor for children is24.37%,the burden factor for old age is 9.12%,and the total burden factor is 33.42%.(2)In 2012-2017,the cumulative number of deaths in Mengzi City was 15,677,the crude death rate was 6.110 million,and the standardized death rate was742.43/100,000.A linear trend chi-square test was performed on the crude mortality rate in 2012-2017,?2=87.96,P<0.001,and the difference was statistically significant.Men mortality was higher than that of women(?2=56172.40,P<0.001).Mortality changes in a "J" shape with increasing age.(3)Among the deaths of the entire population in Mengzi City from 2012 to 2017,the number of deaths of the first major types of diseases(infective,maternal and infant,and nutritionally deficient diseases)was 1,594,and the crude death rate was62.64/100,000.10.17% of the death toll;the second largest category of diseases(chronic non-communicable diseases)was 11548 deaths,and the crude death rate was453.83/100,000,accounting for 73.66% of the total death toll;the third largest category of diseases(injury and poisoning)The death toll was 2,417,and the crude death rate was 94.99/100,000,accounting for 15.42% of the total death toll.(4)The top five causes of death in residents of Mengzi City in 2012-2017 were circulatory diseases,injuries and poisoning,malignant tumors,respiratory diseases and endocrine,nutritional and metabolic diseases.(5)In 2012-2017,the average life expectancy of residents in Mengzi City was74.54 years old,the life expectancy of men was 71.14 years,and the life expectancy of women was 78.46 years old.After the removal of the top five causes of death,residents' life expectancy was 75.36 years old,76.89 years old,76.12 years old,75.97 years old and 75.58 years old.The number of years of potential life loss caused by the total cause of death was 182,023.88 person-years,the life-saving rate was 71.35‰,and the average years of life lost was 11.61 years.Among the main causes of death,the number of potential years of life lost and the number of years of life lost due to injury and poisoning were the highest,being 64,984.29 person-years and 26.89 years respectively.(6)In 2012-2017,the total early death probability of four chronic diseases in Mengzi City was 19.69%,The probability of early death of males other than diabetes was higher than that of females.Conclusions(1)The child's burden factor is high,suggesting that Mengzi City's social support pressure is still relatively large.(2)In 2012-2017,the mortality rate of male residents in Mengzi City was higher than that of females,and the mortality rate of the elderly was the highest.(3)Chronic non-communicable diseases have become the main cause of death in residents of Mengzi City.(4)The top five causes of death in residents of Mengzi City in 2012-2017 were circulatory diseases,injuries and poisoning,malignant tumors,respiratory diseases,endocrine,nutritional and metabolic diseases.(5)In 2012-2017,the life expectancy of residents in Mengzi City was lower than the national level,and the life expectancy of women was higher than that of men;the number of potential life lost caused by injury and poisoning ranks first in the life reduction order.(6)In 2012-2017,the total early death probability of the four chronic diseases in the residents of Mengzi City was higher,and the other three chronic diseases were higher than the females except for diabetes. |
