Prevalence of migraine in the Canadian household population.
Based on data from the 2010 and 2011 Canadian Community Health Surveys and the 2011 Survey of Living with Neurological Conditions in Canada, this article provides information about migraine among people living in private households. In 2010/2011, an estimated 8.3% of Canadians (2.7 million) reported that they had been diagnosed with migraine by a health professional. Females were more likely than males to report migraine: 11.8% versus 4.7%. Migraine prevalence was highest among people in their 30s and 40s: 17.0% for women and 6.5% for men. Compared with the national figure, the prevalence of migraine was lower in Quebec (6.8%) and higher in Manitoba (9.5%), Nova Scotia (9.1%) and Ontario (8.8%). Among people who reported a migraine diagnosis, 42% took prescription medication for their condition, and 56% incurred medication-related out-of-pocket expenses. Migraine was highly comorbid with depression and affected many aspects of daily life including education, work, sleep, and driving.
