Abstract

BACKGROUND: The association between grass pollen exposure and early markers of asthma exacerbations such as lung function changes and increase in airway inflammation is limited. We investigated the associations between short-term grass pollen exposure and lung function and airway inflammation in a community-based sample, and whether any such associations were modified by current asthma, current hay fever, pollen sensitization, age and other environmental factors. METHODS: Cross-sectional and short-term analyses of data from the Melbourne Atopy Cohort Study (MACS) participants (n=936). Lung function was assessed using spirometry. Airway inflammation was assessed by fractional exhaled nitric o..
