In the United States, approximately 8% of the population, or 25 million people, have physician-diagnosed asthma. A large number of Americans report season allergies, and concerns about pollen have heightened in the context of climate change, which can affect the duration, timing, and intensity of the pollen season. Previous work has examined the relationship of pollen with asthma morbidity and has found positive associations. However, these studies have generally assessed relatively short study periods, focused on only a few pollen taxa or groups of taxa, or limited their study to the population as a whole without exploring impacts on sub-groups that may be disproportionately impacted. This project focuses on the relationship between pollen and asthma, and includes an examination of how associations may differ by pollen type and between subgroups, and how associations may be changing over time.
