However, the impact of air pollution on the exacerbation of asthma in adult is not established, due to various approach methods including study design, geography and exposure period. Kim et al. studied it using case-crossover method in adult patients with exacerbating asthma visited multi-center emergency department in Seoul. Unlike to other studies, they suggested that the air pollution was not associated with the exacerbation of adult asthma.
