Spatial epidemiological characteristics of the mortality and probability of premature death caused by chronic obstructive pulmonary disease among residents in Pudong New Area of Shanghai in 2010-2020 / 公共卫生与预防医学

ABSTRACT

Objective To explore the spatial epidemiological characteristics of mortality and probability of premature death caused by chronic obstructive pulmonary disease (COPD) among residents in Pudong New Area of Shanghai from 2010 to 2020, and to provide reference for the formulation of chronic obstructive pulmonary disease prevention and control strategies according to local conditions. Methods The death data of chronic obstructive pulmonary disease were obtained from the local death surveillance system of Pudong New Area. Crude mortality, age-standardized mortality, and probability of premature death caused by COPD in each subdistricts and towns of Pudong New Area were calculated. The geographical information system (GIS) was used to plot the spatial distribution maps of chronic obstructive pulmonary disease death. The trend surface analysis and the spatial autocorrelation analysis were performed to analyze the spatial distribution of chronic obstructive pulmonary disease death. Results The crude mortality, age-standardized mortality and probability of premature death caused by COPD among residents in Pudong New Area between 2010 and 2020 were 58.40/100,000, 22.35/100,000, and 0.26%, respectively. The results of trend surface analysis showed that the crude mortality, age-standardized mortality and probability of premature death caused by COPD gradually increased from north to south. In the east-west direction, the crude mortality, age-standardized mortality, and probability of premature death showed an upward trend from west to east. The global autocorrelation analysis suggested that there existed a positive spatial autocorrelation for the crude mortality, age-standardized mortality, and probability of premature death. The local spatial autocorrelation analysis showed that the high-high clustering areas of COPD crude mortality, standardized mortality and premature mortality were all located in the rural areas of the southeast of Pudong New Area. Conclusion There are urban and rural differences in the mortality of chronic obstructive pulmonary disease among residents in Pudong New Area from 2010 to 2020. The residents living in rural southeast coast of Pudong New Area are more seriously affected by chronic obstructive pulmonary disease and should be paid more attention.
