ABSTRACT
This article presents an epidemiological study of the role of outdoor aeroallergens or environmental pollutants in asthma exacerbations. Much of the evidence comes from ecological "time series" studies that use sophisticated statistical methods to examine temporal associations between daily counts of asthma attacks and daily levels of air pollution at the population level. One methodological problem faced by researchers using time series designs is that the appropriate exposure-response curve for an effect of aeroallergens (pollens) on asthma exacerbations is not known. Meteorological conditions may also contribute to the apparent inconsistencies in the results of time series studies of the health effects of aeroallergens
