Canadian Longitudinal Study on Aging (CLSA)
Canadian Longitudinal Study on Aging logo

The Canadian Longitudinal Study on Aging (CLSA) has been launched to investigate the complexities of the aging process with a view of improving our understanding of the transitions and trajectories of aging. The CLSA is a Canada-wide, 20 year follow-up study of 50,000 people between the ages of 45 and 85 years at baseline. Thirty thousand of these participants will be asked to provide in-depth information through physical examinations and biological specimen collections (Comprehensive Cohort). The remaining 20,000 (Tracking Cohort) will be asked to provide the common core information set by questionnaires only.

This initiative comes at a time when the baby boomers are moving into late middle-age and retirement, a demographic shift that has created a critical need for aging research to inform interventions, programs and policies, and to promote healthy aging for today's and tomorrow's seniors. This research is needed if future interventions and policies are to reach the objectives of improving health, allowing individuals to maintain desired levels of activity into late life, and increasing the lifespan as well as quality of life.
