About the study
The Canadian Longitudinal Study on Aging (CLSA) is a large, national, long-term study that will follow approximately 50,000 men and women between the ages of 45 and 85 for at least 20 years.
The ultimate aim of the CLSA is to find ways to improve the health of Canadians by better understanding the aging process and the factors that shape the way we age.
The study takes an integrative approach, examining healthy aging through a number of different lenses. Study investigators will collect a wide range of information about the changing biological, medical, psychological, social, lifestyle and economic aspects of people’s lives.
The study is a longitudinal design, meaning that it will follow people over a long period of time. It is also supplemented with a series of cross-sectional snapshots that will allow for immediate and continual research results.
The benefits of the CLSA include:
- Contributing to the identification of ways to prevent disease and improve health services
- Developing better understanding of the impact of non-medical factors, such as economic prosperity and social changes, on people as they age
- Answering questions that are relevant to decision-makers to improve health policy and inform government programs and services
As of March 23, 2013 they have over 26,000 study participants.
