Mortality rate and change trend of respiratory diseases in Tongzhou District,Beijing from 2016 to 2022
Objective To analyze the change characteristics of respiratory disease death data in Tongzhou District of Beijing in recent 7 years,and to provide scientific basis for the government and relevant departments to formulate prevention and control strategies and measures.Methods Through the data of respiratory disease death cases of registered population in Tongzhou District of Beijing from 2016 to 2022 in the Cause of Death Surveillance Subsystem of China Disease Prevention and Control Information System,the change trend,gender and age distribution characteristics,and regional distribution differences of respiratory disease mortality before and after the outbreak of novel coronavirus infection(COVID-19)were analyzed.Chi-square test was used to test the difference of mortality,and trend Chi-square test was used to test the change trend.P＜0.05 was considered to be statistically significant.Annual percent change(APC)was used to reflect the change of mortality of respiratory diseases from year to year.Results From 2016 to 2019,the standardized mortality rates of respiratory diseases among registered residents in Tongzhou District of Beijing were relatively stable,and the standardized mortality rates were 31.74/105,30.58/105,30.94/105 and 32.93/105,respectively.From 2020 to 2021,the standardized mortality rates of registered residents in Tongzhou District showed a continuous decreasing trend,and the rates were 24.48/105 and 20.30/105,respectively(x2trend=-190.05,P＜0.01).In 2022,the standardized mortality rate increased significantly to 36.80/105(x2=63 565.46,P＜0.01).The standardized mortality rate of respiratory diseases of male residents was higher than that of female residents.The mortality rate of respiratory diseases increased with age.The mortality rate of registered residents in the age group of 80 years old and above in 2022 was significantly higher than those in 2016 to 2021,and the mortality rate of the age group of 85 years old and above was as high as 2 000.87/105.The standardized mortality rates of chronic lower respiratory diseases,pneumonia and pulmonary infections were stable from 2016 to 2019,decreased significantly from 2020 to 2021,and reverted in 2022(all P＜0.01).The standard mortality rate for pulmonary infections in 2022 was 12.61/105,the highest level ever recorded.In 2020-2021,86.67％of townships/streets had a lower mortality rate than that in 2016-2019,and 73.33％(11/15)of townships/streets in 2022 had a higher mortality rate than that in 2016-2019.Conclusions Before and after the outbreak of COVID-19,the mortality rate of respiratory diseases in Tongzhou District of Beijing showed a trend of decreasing first and then increasing.There were gender,age and regional differences in the overall mortality rate and standardized mortality rate,and targeted prevention and control measures should be formulated.
