- Abstract
- We aimed to investigate the association between short-term exposure to air pollution and acute exacerbation of asthma requiring emergency departments (EDs) visit. We identified from the National Health Insurance Service environmental database of Korea 55,961 patients who visited EDs with asthma as a primary cause in Incheon during the period of 2013 and 2017. We estimated exposure to ozone (O3), particulate matter < 2.5μm (PM2.5), particulate matter < 10μm (PM10), nitrogen dioxide (NO2), sulfur dioxide (SO2) and carbon monoxide (CO). We conducted a quasi Poisson regression as a time series analysis using generalized additive models to examine the association between air pollution exposure and EDs visit for asthma. We provide evidence that exposure to air pollution may increase the risk of EDs visit for asthma in Incheon. Given our findings, public health interventions to reduce levels of air pollutants including O3 and PM2.5 should be conducted.
