Abstract

Dear Editor,
The prevalence of pollen-induced health problems is expected to increase as climate change worsens. Previous research has found that adults had worse pollen-induced airway impairment compared to children. We hypothesized that different lifestyle and environmental factors and/or lung aging may explain why the different health impacts of pollen across age groups. To the best of our knowledge, no adult population-based study has assessed the relationships between ambient pollen exposure and post-bronchodilator (BD) lung function as a measure of fixed airflow obstruction, or gas transfer as a measure of parenchymal damage. Studies that investigated pre-BD lung function in adults have reported no significant changes in and out of the pollen season, but the sample sizes were small and only stratified by asthma and/or seasonal allergic rhinitis. However, there are more individual, lifestyle and environmental factors to consider that may interact with each other and pollen on lung function...
