Brief Summary:
To examine the role of outdoor pollen grains and fungal spores in the exacerbation of asthma and to produce forecasting models to predict days of high concentration
Detailed Description:
Asthma is a growing problem and outdoor allergens play a role in exacerbation of many cases A clearer understanding of this role and its magnitude and a means of controlling the effects of outdoor allergen exposures is needed We propose Poisson time-series and conditional panel studies to test these hypotheses 1 The incidence of acute asthma attacks as measured by urgent care inhalation treatments and hospitalizations for asthma has a dose-dependent relationship with exposure to specific outdoor allergens 2 Specific sensitization to outdoor allergens is a risk factor for having an acute attack and 3 Exposure conditions that lead to acute asthma attacks can be forecast creating an opportunity to reduce asthma morbidity and mortality ny targeting pretreatment andor exposure controls
