Abstract
Eosinophilic asthma is one of the most common subtypes of asthma diagnosed in adulthood, with around 50% of cases of mild to severe asthma of the eosinophilic subtype [1]. Although it is well acknowledged that residential environment plays a critical role in the progression of early-onset or late-onset asthma [2, 3], no prior study has had the primary objective of evaluating the association between residential greenness and eosinophilic asthma. The aim of our study was to explore whether there is an association between residential greenness and eosinophilic asthma in adults. This study suggests a negative association between individual-level exposures to greenness and eosinophilic asthma in adults, providing new evidence to the existing investigations on health effect of green space https://bit.ly/3fVKWS3</p>
