Objective To investigate the differences in the importance of meteorological and environmental factors on the acute onset of chronic obstructive pulmonary disease(COPD).Methods The clinical data of 3 460 patients with acute onset of COPD admitted to Liuzhou Workers'Hospital from January 2021 to December 2023,as well as the me-teorological data and air quality daily report data of Liuzhou City during the same period were selected as the research objects.Spearman correlation analysis and multiple stepwise regression analysis were performed on each factor and the number of acute COPD visits,and a COPD prediction model was established and its fitting effect was analyzed.Results The number of acute COPD patients was negatively correlated with average temperature and average relative humidity(r=-0.539,-0.589,both P<0.05),and positively correlated with SO2 and PM2.5(r=0.613,0.632,both P<0.05).Multiple regression analysis showed that daily temperature difference,relative humidity and PM2.5 had signifi-cant effects on the number of patients with acute COPD(all P<0.05).Conclusion The effects of daily temperature dif-ference,relative humidity and PM2.5 on the acute onset of COPD are significant and should be emphasized.
