|Dataset Full Name||Canadian Longitudinal Study on Aging|
CLSA is an ongoing, national, longitudinal study following approximately 50,000 adults 45-85 years old living in Canada and is a strategic initiative of the Canadian Institutes of Health Research (CIHR). Recruitment began at multiple sites from 2010 to 2015 . Participants will be followed for at least 20 years with data being collected every 3 years. The CLSA collects information on biological, medical, psychological, economic, social and lifestyle factors. It is designed to develop a better understanding of how those factors affect health and the development of disease and disability as people age. The CLSA will be linked to health administration databases (94% participants consented) that will provide complimentary information regarding medication use, health service utilization, and mortality.
