Epidemiological characteristics of respiratory disease mortality in residents of Baoshan，Shanghai 2009‒2020

Abstract

ObjectiveTo investigate the epidemiological characteristics of respiratory disease mortality in Baoshan residents during the period of 2009‒2020.MethodsRespiratory disease deaths of Baoshan residents from 2009‒2020 were collected. ICD-10 codes were used to classify the causes of death， and R-4.2.1 was applied for statistical analysis. The average annual percent change （AAPC） of standardized mortality rates of different respiratory diseases were analyzed by using Joinpoint 4.9.0.0.ResultsThe average annual mortality rate of respiratory diseases in Baoshan from 2009 to 2020 was 58.86/105， and the standardized mortality rate was 35.62/105， which was the 3rd leading cause of mortality. The mortality rate of respiratory diseases was higher in men than in women （χ2=46.70， P<0.001）. COPD ranked first among respiratory diseases in Baoshan from 2009 to 2020， followed by pneumonia， asthma and pneumoconiosis in that order. The standardized mortality rate for COPD decreased from 38.66/105 in 2009 to 19.88/105 in 2020 （AAPC=-6.6%， 95%CI： -8.2% to -4.9%， P<0.001）. The standardized mortality rate of asthma decreased from 2.86/105 in 2009 to 1.43/105 in 2020 （AAPC=-5.8%， 95%CI： -8.8% to -2.8%， P<0.01）. The standardized mortality rate of pneumoconiosis decreased from 0.64/105 in 2009 to 0.12/105 in 2020 （AAPC=-7.4%， 95%CI： -13.0% to -1.5%， P<0.05）. The standardized mortality rate for pneumonia decreased from 2.63/105 in 2009 to 0.70/105 in 2020 （AAPC=-6.2%， 95%CI： -12.2% to 0.2%， P=0.056）， but not statistically significant. The annual average mortality rates of COPD， pneumonia and asthma were all highest in January. Crude mortality rates for COPD （χ2=2 669.01， P<0.001）， pneumonia （χ2=217.82， P<0.001）， asthma （χ2=100.09， P<0.001）， pneumoconiosis （χ2=26.46， P<0.001） and all categories of respiratory diseases （χ2=2 995.84， P<0.001） increased with age showed an increasing trend. The crude mortality rates for COPD （χ2=101.69， P<0.001）， pneumonia （χ2=7.39， P<0.01） and asthma （χ2=7.41， P<0.01） were higher in the central than in the northern part of Baoshan District， while the crude mortality rate for COPD （χ2=19.97， P<0.001） was higher in the central than in the southern part.ConclusionThe attention should be focused on COPD； increased detection in males and the elderly， especially in winter and spring； and a good balance between environmental and economic when planning the regional development.
