Trends in the mortality and premature death probability of chronic respiratory diseases among residents in Benxi City,Liaoning Province,2010-2021
Objective To analyze the changing trends in the mortality and premature death probability of chronic respiratory diseases(CRD)in Benxi City,Liaoning Province from 2010 to 2021,and to provide a basis for developing CRD prevention and control measures.Methods The death data were collected from the Surveillance System for Death Causes in Benxi City.SPSS 24.0 software was used to statistically analyze the mortality,standardized mortality,premature death probability,etc.Mortality difference dissembling method was employed to perform differential decomposition analysis on the mortality of population.Differences in the mortalities of males and females were compared by using x2 test,and Joinpoint 4.9.1 software was applied to calculating the changing trends in the rates.Results From 2010 to 2021,the crude mortality of CRD in the residents in Benxi City was 31.83/100,000,and the standardized mortality 35.87/100,000.Differences in the changing trends in the crude mortality and standardized mortality were not statistically significant(P＞0.05).The crude mortality of chronic obstructive pulmonary disease(COPD)in 2010-2021 was 21.40/100,000,and the standardized mortality 24.76/100,000.Differences in the changing trends in the crude mortality was not statistically significant(P＞0.05),and the standardized mortality showed a downward trend(APC=-6.34％,P＜0.05).The mortalities of CRD and COPD were both higher in the males than in the females.The probability of premature death from CRD decreased from 0.78％in 2010 to 0.39％in 2021,and the probability of premature death from COPD from 0.64％in 2010 to 0.25％in 2021,with statistically significant differences in both the changing trends(APC=-6.02％,APC=-8.34％,both P＜0.05).The analysis results based on the difference dissembling method revealed that the crude mortalities of CRD in 2010-2021 increased from 22.03/100,000 to 28.31/100,000 due to the population factor,with a population contributing rate being 592.20％.The crude mortality of COPD increased from 17.41/100,000 to 21.40/100,000 on account of the population factor,with a population contributing rate of 2,858.74％.Conclusion The crude mortalities of CRD and COPD in Benxi City during 2010-2021 showed upward trends,while the standardized mortality and premature death probability presented decreasing trends.Population aging is the main cause for the increase of crude mortality as well as the decrease of standardized mortality and premature death probability.The elderly and male residents are the key groups for prevention and control.
