Seasonality ambient temperatures and hospitalizations for acute exacerbation of COPD: a population-based study in a metropolitan area

摘要

BackgroundExcluding the tropics, exacerbations of chronic obstructive pulmonary disease (COPD) are more frequent in winter. However, studies that directly relate hospitalizations for exacerbation of COPD to ambient temperature are lacking. The aim of this study was to assess the influence of temperature on the number of hospitalizations for COPD.
