Long-term exposure to air pollution and mortality in a prospective cohort: The Ontario Health Study
The researchers investigated the association between long-term exposure to air pollution and mortality using data from 88,615 participants in the Ontario Health Study from 2009 to 2017. They assessed exposure to fine particulate matter (PM2.5) and nitrogen dioxide (NO2) at participants’ residences and analyzed non-accidental, cardiovascular, and respiratory mortality risks using Cox proportional hazard models. Stronger associations were observed among physically active participants, smokers, and individuals with lower household income. These findings suggest that further improvements in air quality may reduce mortality risk, even in regions with low air pollution levels.
Dietary assessment is a critical element of health research – Perspective from the Partnership for Advancing Nutritional and Dietary Assessment in Canada
Article reposant sur des opinions qui fait valoir que, même si l’évaluation des apports alimentaires est une tâche difficile, elle n’est pas impossible. Les auteurs croient qu’un renforcement des capacités et des possibilités de financement devraient être facilement disponibles pour développer la recherche. Si l’on disposait de ces éléments, il y aurait une meilleure compréhension au Canada et ailleurs.
