Study On The Death Causes And Burden Of Chronic Disease Among Residents In Linxiang District From 2013 To 2018

ObjectiveIn order to understand the death causes of chronic diseases among residents in Linxiang District,and to analyze the main chronic diseases which make the residents lost their life.Furthermore,clarify the focus and direction of chronic disease prevention and control.Eventually,providing a reference for the Linxiang District to make prevention strategies of chronic disease.At the same time,laying a theoretical foundation for evaluating the effect of the demonstration area of comprehensive prevention and control of chronic diseases.MethodsCollecting the death cause data in Linxiang District from 2013 to 2018,and calculate the death causes according to the standard of death cause.Then,according to the 10 th edition of the International Classification of Diseases(ICD-10)to encode the death causes.And,by calculating crude mortality,standardized mortality and order of death with different diseases,populations,and years to describe the characteristics of death in chronic disease.The standardization rate is calculated by using the 2010 national census demographic data.In addition,using the probability of early death,PYLL,SPYLL,AYLL,PYLLR,SPYLLR,life expectancy to assess the burden of chronic diseases.The average annual change percentage(APC)is used to assess the time trends of death in chronic disease from 2013 to 2018.Results(1)From 2013 to 2018,the crude death rate of all causes death was594.33/100,000(APC=2.84%,P>0.05),and the standardized death rate was641.98/100,000(APC=2.12%,P>0.05),the trend of increasement was not statistically significant.The males mortality rate was higher than females(P<0.05).In 6 years,there was no significant change of mortality rate for males(P>0.05),but for thefemales increased by 4.81% per year(APC=4.81%,P<0.05).The deaths proportion of chronic diseases was accounted for 80.65%,the crude death rate of chronic diseases was 479.32/100,000(APC=2.94%,P>0.05),and the standardized death rate was541.18/100,000(APC=1.92%,P>0.05),the upward trend was not statistically significant.And the males mortality was higher than females(P<0.05),the time trend of both were not statistically significant.(2)The top 5 of chronic disease death in residents of Linxiang District from 2013 to 2018 were circulatory system disease(56.25%),respiratory system disease(15.70%),malignant tumor(13.12%),digestive system disease(5.80%),endocrine and metabolic system disease(3.10%).The top 3 of chronic diseases death were same among the entire population,male and female.First,for circulatory system diseases,the crude mortality rate of was 269.63/100,000(APC=3.67%,P>0.05),and the standardized rate was 304.17/100,000(APC=2.53%,P>0.05).The males mortality rate was higher than females(P <0.05),there was no significant change for males of mortality rates in 6 years,and for females increased by 6.93% per year(APC=6.93%,P<0.05).Among the circulatory diseases,the top 3 death causes were cerebrovascular disease(51.70%),ischemic heart disease(22.33%),and hypertension(16.37%).Second,for respiratory diseases,the crude mortality of was 75.27/100,000(APC=3.98%,P>0.05),and the standardized mortality was 85.83/100,000(APC=2.84%,P>0.05).The mortality rate of males was higher females(P<0.05).Among the respiratory diseases,the top 3 death causes were chronic obstructive pulmonary disease(40.16%),chronic pneumonia(26.97%),and emphysema(15.19%).Finally,for malignancies,the crude mortality of was 62.87/100,000(APC=2.94%,P>0.05),and the standardized mortality was 70.52/100,000(APC = 1.41%,P>0.05).Males mortality was higher than females(P<0.05).Among the malignant tumors,the top 3 causes death were lung cancer(22.44%),liver cancer(16.19%),and gastric cancer(14.98%).(3)From 2013 to 2018,the premature death rate of the four major chronic diseases was 17.47%(APC=0.30%,P>0.05).Except the premature death rates of respiratory diseases decreased by 8.52% per year(APC=-8.52%,P<0.05),the trends of circulatory diseases,malignant tumors,and diabetes had no significant(P>0.05).(4)The life expectancy of residents in Linxiang District from 2013 to 2018 was74.40 years.The main chronic diseases that caused people life loss were circulatory system diseases(PYLL=36684 person-years),malignant tumors(PYLL=18324person-years),and digestive system diseases(PYLL=10400 person-years).And digestive diseases(AYLL = 25.24 years),urogenital diseases(AYLL = 22.48 years),and malignant tumors(AYLL = 21.11 years)were more harmful to premature death.ConclusionsChronic diseases have become the primary public health problem that threatens the lives and health of residents in Linxiang District.The death of chronic diseases and the premature death rates of four major chronic diseases were both high,and there was no trend of decreasment.The life expectancy of people was low,and the main chronic diseases that caused a serious loss of life were circulatory system diseases,malignant tumors,and digestive system diseases,and the burden of those diseases was heavy.
