Increase in Asthma Associated with Indoor Allergens and Inactivity

Changes in lifestyle leading to greater inactivity and increased exposure to indoor allergens contributes to the dramatic increase in asthma in Western society, according to evidence presented at the annual meeting of the American College of Allergy, Asthma, and Immunology.
"Increases in asthma over the last 30 years have been in perennial, or recurrent, asthma. The strongest risk factor that has been identified is sensitization to indoor allergens," said Thomas A. E. Platts-Mills, M.D., University of Virginia in Charlottesville.
"Since it is not clear that concentrations of indoor allergens have increased, the implication is that some other aspect of lifestyle ubiquitous in Western society must have an increased effect on asthma, " he said.
The most pervasive changes in lifestyle are those that followed the introduction of television, computers, and other forms of home entertainment.
