Canadian Longitudinal Study on Aging (CLSA)

Canadian Longitudinal Study on Aging (CLSA) The Canadian Longitudinal Study on Aging (CLSA) | Étude longitudinale canadienne sur le vieillissement (ÉLCV)
www.clsa-elcv.ca Drs.

The CLSA will collect information on the changing biological, medical, psychological, social, and economic aspects of people’s lives. These factors will be studied in order to understand how, individually and in combination, they have an impact in both maintaining health and in the development of disease and disability as people age. The CLSA will be one of the most comprehensive studies of its kind undertaken to date, not only in Canada but around the world. Dr. Parminder Raina (McMaster University, Hamilton) is the lead Principal Investigator of the CLSA. Christina Wolfson (McGill University, Montreal) and Susan Kirkland (Dalhousie University, Halifax) are Co-Principal Investigators of the CLSA. Raina, Wolfson and Kirkland, along with a team of more than 160 investigators and collaborators from several Canadian universities have participated in the development of this innovative, interdisciplinary study.

Une nouvelle étude de Université McGill et de Université Laval, qui fait appel aux données de l’ÉLCV, démontre toute l’importance des liens sociaux pour la santé mentale avec le vieillissement.

L’équipe de recherche a établi que les personnes âgées dont les environnements sociaux sont plus stimulants ont tendance à avoir une meilleure santé cognitive.

C’est la première étude à créer des profils sociaux détaillés, qui combinent de multiples facteurs comme les cercles sociaux, la participation et le soutien, pour en examiner les relations avec la santé cognitive.💬🧠

New research from McGill University and Université Laval, using data from the CLSA, shows just how important social connection is for brain health as we age.

Researchers found that older adults with more engaged social environments tend to have better cognitive health outcomes.

This is the first study to create detailed social profiles — combining multiple factors like social networks, participation, and support — and examine how those patterns relate to cognitive health.💬🧠

Research by an interdisciplinary team from McGill University and Université Laval provides new insights into the links between social factors and cognitive health among aging adults. While previous research had found positive correlations between specific measures of social connectedness and a vari...

Selon une analyse auprès de plus de 30 000 adultes qui participent à l’ÉLCV, dirigée par la Dre Tetyana Kendzerska, les personnes les plus vulnérables à l’apnée obstructive du sommeil risquent nettement plus d’éprouver des troubles de santé mentale, tant au moment de l’évaluation que des années plus t**d.

« Ces travaux font ressortir l’importance de démarches de soins intégrées, où le sommeil, la santé physique et la santé mentale sont évalués ensemble plutôt qu’isolément », ajoute la Dre Kendzerska.

An analysis of more than 30,000 adults in the CLSA, led by Dr. Tetyana Kendzerska, has found that individuals at high risk of obstructive sleep apnea have significantly higher odds of experiencing mental health conditions both at the time of assessment and years later.

“This work highlights the importance of integrated approaches to care, where sleep, physical health, and mental health are considered together rather than in isolation,” said Dr. Kendzerska.

"The data we've collected allows us to understand aging in ways that weren't possible before."

In a recent McMaster University News feature, Parminder Raina, Lead Principal Investigator of the Canadian Longitudinal Study on Aging and Scientific Director of the McMaster Institute for Research on Aging, reflects on the CLSA as one of the world's most comprehensive population-based studies on aging.

Following more than 50,000 Canadians over two decades, the CLSA is generating high-quality evidence shaping research, policy and practice across mobility, brain health and social context—while informing initiatives such as mobility research through McMaster Monitoring My Mobility (MacM3) led by Marla Beauchamp, in Canada and internationally.

« Les données que nous recueillons nous permettent de comprendre le vieillissement de façons jusque-là inimaginables. »

Dans un récent article de Brighter World (un monde meilleur) de McMaster University , Parminder Raina, chercheur principal en chef de l’Étude longitudinale canadienne sur le vieillissement (ÉLCV) et directeur scientifique du McMaster Institute for Research on Aging , présente l’ÉLCV comme l’une des études populationnelles sur le vieillissement les plus complètes dans le monde.

L’ÉLCV, qui suit plus de 50 000 Canadiennes et Canadiens pendant plus de deux décennies, produit des données probantes de qualité qui façonnent la recherche, les politiques et la pratique sur la mobilité, la santé cérébrale et le contexte social, tout en éclairant des initiatives comme les recherches sur la mobilité de l’étude McMaster Monitoring My Mobility (MacM3), dirigée par Marla Beauchamp au Canada et ailleurs dans le monde.
