TL;DR: In this large population-based cohort study, living close to heavy traffic was associated with a higher incidence of dementia, but not with Parkinson's disease or multiple sclerosis.
Journal ArticleDOI
Exposure to ambient air pollution and the incidence of dementia: A population-based cohort study.
Hong Chen,Jeffrey C. Kwong,Ray Copes,Perry Hystad,Aaron van Donkelaar,Karen Tu,Jeffrey R. Brook,Mark S. Goldberg,Randall V. Martin,Brian J. Murray,Andrew S. Wilton,Alexander Kopp,Richard T. Burnett +12 more
TL;DR: In this large cohort, exposure to air pollution, even at the relative low levels, was associated with higher dementia incidence, and associations were robust to all sensitivity analyses examined.
Journal ArticleDOI
Risk of incident diabetes in relation to long-term exposure to fine particulate matter in Ontario, Canada.
Hong Chen,Richard T. Burnett,Jeffrey C. Kwong,Paul J. Villeneuve,Mark S. Goldberg,Robert D. Brook,Aaron van Donkelaar,Michael Jerrett,Randall V. Martin,Jeffrey R. Brook,Ray Copes +10 more
TL;DR: Long-term exposure to ambient PM2.5 may contribute to the development of diabetes, according to a population-based cohort study conducted in Ontario, Canada.
Journal ArticleDOI
Spatial Association Between Ambient Fine Particulate Matter and Incident Hypertension
Hong Chen,Richard T. Burnett,Jeffrey C. Kwong,Paul J. Villeneuve,Mark S. Goldberg,Robert D. Brook,Aaron van Donkelaar,Michael Jerrett,Randall V. Martin,Alexander Kopp,Jeffrey R. Brook,Ray Copes +11 more
TL;DR: An association between PM2.5 and incident hypertension is found, supported by various sensitivity analyses, such as investigating several time windows of exposure and controlling for potential changes in the risk of hypertension over time.
Journal ArticleDOI

Li Bai,Hong Chen,Marianne Hatzopoulou,Michael Jerrett,Jeffrey C. Kwong,Richard T. Burnett,Aaron van Donkelaar,Ray Copes,Randall V. Martin,Keith Van Ryswyk,Hong Lu,Alexander Kopp,Scott Weichenthal +12 more
TL;DR: Exposure to traffic-related air pollution including ultrafine particles and NO2 may increase the risk for incident hypertension and diabetes in Canadian-born residents aged 30 to 100 years.
