Asthma is a chronic disease that affects approximately one in 20 Canadians. Research has shown an association between lower socioeconomic status and poorer outcomes for asthma patients, including more hospital admissions and emergency room visits and a greater likelihood of a fatal attack. Excessive use of short-acting bronchodilators, which help manage acute episodes of asthma, indicates inadequate asthma control and has been associated with poorer outcomes. Larry Lynd is investigating whether there is a relationship between lower socioeconomic status-measured by education, income, occupation and characteristics of residence-poor asthma control, and the overuse of bronchodilators. Confirming that relationship could determine whether inappropriate management of asthma is at least partially responsible for poorer outcomes. Larry hopes this research can lead to policies and strategies aimed at improving the management of asthmatics of lower socioeconomic status.
