CLSA links with CANUE to release data on environmental health

Thursday, May 31, 2018

The Canadian Longitudinal Study on Aging (CLSA) and the Canadian Urban Environmental Health Research Consortium (CANUE) have collaborated to link data on air quality, neighbourhood factors, weather and climate, and greenness indicators to CLSA data on health and aging, to enable research on how environmental factors affect the ways in which Canadians age.

The linked data includes estimated exposures of sulfur dioxide, nitrogen dioxide, ozone and fine particulate matter, as well as information about nighttime light, normalized difference vegetation index (i.e. greenness), data on weather and climate, material and social deprivation indices and the Canadian Active Living Environments (i.e. walkability) index.

The CLSA is a national cohort study of aging funded by the Canadian Institutes of Health Research (CIHR). The initiative is led by Dr. Parminder Raina of McMaster University, Dr. Christina Wolfson of McGill University and Dr. Susan Kirkland of Dalhousie University.

CANUE is a CIHR-funded initiative, which gathers and develops measures related to a range of environmental factors to study how they affect a wide variety of health outcomes. One of CANUE’s main goals is to enable evidence-based strategies that help plan healthy neighbourhoods and cities across Canada.

“We know that environmental factors play an important role in healthy aging." said Dr. Jeffrey Brook, faculty member at Dalla Lana School of Public Health and CANUE Scientific Director. “Enriching the CLSA with a wide range of indicators such as air quality, neighbourhood greenness and walkability will give Canadian researchers an unprecedented capacity to better understand this relationship."  

The linked data are available to researchers as of June 2018.
