Introduction to the Cohort
The Canadian Study of Health and Aging (CSHA) is prospective cohort study of dementia. A community sample was randomly selected among men and women throughout Canada, aged 65 years of older during 1991-1992. Participants have undergone follow-up assessments every 5 years since enrollment, ending in 2001. Of the 6,434 participants who did not have dementia at baseline, 4,615 (60% female) participants completed the 5-year follow-up in 1996-1997.

Ethnicity Breakdown
The cohort is a representative sample of Canadian men and women aged 65 and older living in urban and rural Canada from all 10 provinces. No other information on ethnicity or race has been reported.
