Asthma is a chronic inflammatory disorder of the airways that causes coughing, shortness of breath, chest tightness and wheezing. Quality of life can be affected not only by asthma attacks, but also by absences from work and limitations in other activities.1

In 2009, 8.1% of Canadians 12 years and older reported they had been diagnosed with asthma by a health professional. This rate did not significantly change from 2001 to 2009.

Throughout the period, females were more likely than males to report that they had asthma—9.4% compared with 6.7% in 2009 (Chart 1).

The proportion of residents reporting asthma was higher than the national average in Manitoba (10.7%), and lower than the national average in Quebec (7.3%) and Nunavut (3.5%—which should be interpreted with caution).
