Linked CANUE and administrative health databases: PopDataBC and MCHP
March 27th (9 am pacific | 12 noon eastern)
Linkage of CANUE exposure data with provincially managed administrative health databases offers new and exciting opportunities for environmental health research. To date, CANUE data has been linked to data held by Population Data BC (PopData), Manitoba Centre for Health Policy (MCHP), and the New Brunswick Institute for Research, Data and Training (NB-IRDT).
Kelly Sanderson is the Lead of Business and Initiatives Development at Population Data BC. She works closely with BC government and BC SUPPORT Unit partners on joint data initiatives funded by the Strategy for Patient-Oriented Research (SPOR). She joined the organization in 2009 and was previously the Data Access Unit Lead where she enjoyed working with and guiding many researchers through the Data Access Request process. Her educational background and related professional experience was in Urban Planning and Geographical Information systems so she readily appreciates the value CANUE data brings as a new PopData holding.
Charles Burchill has been an Associate Director at the Manitoba Centre for Health Policy, University of Manitoba, since 2006. Prior to this role, he worked as a research analyst at MCHP starting in 1992. He is actively involved with Health and Social policy-related research using Manitoba administrative health and social data. The repository of data represents over 80 distinct programs and databases with linkable data in the areas of health, family services, justice, and education. His graduate work was in field ecology, with the CANUE data providing an opportunity to bring his interests full circle. The CANUE data represents an important source of built environment and environmental data that can be linked through small area geographies to the overall repository.
Dr. Ted McDonald is a Professor of Economics at the University of New Brunswick in Fredericton, Academic Director of the NB Research Data Centre, Director of the NB Institute for Research, Data and Training and the New Brunswick lead for the Maritime SPOR SUPPORT Unit. He holds a Ph.D. and a Master of Commerce in Economics from the University of Melbourne. Dr. McDonald’s main areas of research include health status and labour market issues of immigrants, rural residents, minority groups and other subpopulations, as well as an ongoing program of research on the socioeconomic and demographic determinants of cancer.
Dany Doiron is a research associate in the Respiratory Epidemiology and Clinical Research Unit at the Research Institute of the McGill University Health Centre (RI-MUHC) and is CANUE’s data linkage lead. Dany holds a Masters degree in Public Policy (Simon Fraser University) and PhD in Epidemiology (University of Basel). His research explores the effects of environmental exposures on health.
About the Speaker: Dr. Jeffrey Brook
Dr. Jeffrey Brook is CANUE’s Principal Investigator and Scientific Director. He is also an Assistant Professor at the University of Toronto’s Dalla Lana School of Public Health and Department of Chemical Engineering and Applied Chemistry. He has 25 years of experience as an Environment Canada scientist working at the science-policy interface. He is one of Canada’s leading experts in air quality, recognized at all levels of government and academically, including for his substantial contributions in air pollution health research. Dr. Brook has led scientific assessments to inform policy nationally and internationally, and advised multi-stakeholder groups shaping policy.
This webinar will provide an overview of the CANUE data and research opportunities made possible by linking CPTP’s individual lifestyle, genetic and behavioural data with CANUE’s environmental exposure metrics. This collaboration provides health researchers easy access to standardized urban environmental exposures, allowing them to tackle real-world problems related to exposures and the subsequent health outcomes. Ultimately, new knowledge enabled by the CANUE-CPTP partnership will help identify cost-effective actions that promote healthy childhood development and aging, reduce the burden of chronic disease, and minimize the impact of changing environments.

Examining the Shape of the Association between Low Levels of Fine Particulate Matter and Mortality across Three Cycles of the Canadian Census Health and Environment Cohort.

Ambient fine particulate air pollution with aerodynamic diameter ≤2.5 μm (PM2.5) is an important contributor to the global burden of disease. Information on the shape of the concentration-response relationship at low concentrations is critical for estimating this burden, setting air quality standards, and in benefits assessments.
We examined the concentration-response relationship between PM2.5 and nonaccidental mortality in three Canadian Census Health and Environment Cohorts (CanCHECs) based on the 1991, 1996, and 2001 census cycles linked to mobility and mortality data.
Census respondents were linked with death records through 2016, resulting in 8.5 million adults, 150 million years of follow-up, and 1.5 million deaths. Using annual mailing address, we assigned time-varying contextual variables and 3-y moving-average ambient PM2.5 at a 1×1 km spatial resolution from 1988 to 2015. We ran Cox proportional hazards models for PM2.5 adjusted for eight subject-level indicators of socioeconomic status, seven contextual covariates, ozone, nitrogen dioxide, and combined oxidative potential. We used three statistical methods to examine the shape of the concentration-response relationship between PM2.5 and nonaccidental mortality.
The mean 3-y annual average estimate of PM2.5 exposure ranged from 6.7 to 8.0 μg/m3 over the three cohorts. We estimated a hazard ratio (HR) of 1.053 [95% confidence interval (CI): 1.041, 1.065] per 10-μg/m3 change in PM2.5 after pooling the three cohort-specific hazard ratios, with some variation between cohorts (1.041 for the 1991 and 1996 cohorts and 1.084 for the 2001 cohort). We observed a supralinear association in all three cohorts. The lower bound of the 95% CIs exceeded unity for all concentrations in the 1991 cohort, for concentrations above 2 μg/m3 in the 1996 cohort, and above 5 μg/m3 in the 2001 cohort.
In a very large population-based cohort with up to 25 y of follow-up, PM2.5 was associated with nonaccidental mortality at concentrations as low as 5 μg/m3.
The journal Epidemiology recently interviewed study co-author and CANUE member Dan Crouse about exposure to fine particulate matter and diabetes in the Canadian Census Health and Environment Cohort.
