Analysis on the trend of COPD mortality of the residents in Wuhan during 2008-2019

Objective To analyze the mortality rate of chronic obstructive pulmonary disease(COPD)and its trend in residents in Wuhan from 2009 to 2018.Methods COPD mortality data from 2009 to 2018 were from Wuhan population based mortality surveillance system.The crude and standardized mortality rates of COPD were calculated of different geographic distribution,different gender and different age,and the trend over years were analyzed.The software SAS 9.4 was used for linear regression analysis,and the annual percent change(APC)was calculated.Results The crude mortality rate and the standardized mortality rate of COPD were 33.01/100000 and 23.03/100000 respectively in residents in Wuhan from 2009 to 2018.The crude mortality rate showed an increasing trend from 2009 to 2018 and the APC was 4.08%,(P<0.05).The crude mortality rate was 41.23/100000 in males and 24.47/100000 in females(χ²=6.37,P<0.05).The crude mortality rate was 35.29/100000 in rural areas and 32.28/100000 in urban areas,and there was no statistical significance(χ²=0.20,P>0.05).The crude mortality rate showed increasing trends in males and rural areas,and the APC were 4.08%(P<0.05)and 5.10%(P<0.05)respectively.There was no statistical significance in the trends of females and urban areas,and the APC was 2.02%(P>0.05).Except for those aged 35-45 years old,the standardized mortality rate of COPD in all age groups showed a downward trend from 2009 to 2018.Conclusion The COPD mortality in residents in Wuhan increased from 2009 to 2018.More attention should be paid to reducing COPD mortality in rural residents,males and elderly population.
