Efforts to reduce healthcare inequalities amongst the Canadian population is hampered and complicated by the uneven distribution of environmental stressors, negatively altering cardiovascular incidences. As traffic increases along with urban development and population growth, so does the exposure levels of noise and air pollution, which can affect cardiovascular health. The purpose of the work seeks to understand the effects of multiple exposures on cardiovascular disease (CVD), while considering preventative actions already implemented by the multiple levels of government, as cardiovascular illness is projected to increase in future years along with healthcare costs. The study has taken data from the Canadian Community Health Survey (CCHS), Environment Canada, Toronto Public Health, and the City of Toronto’s Wellbeing open source catalogue to conduct a binary logistic regression. CCHS participants have been assessed for environmental exposures at the geographic level of postal codes for nitrogen dioxide (NO2), fine particulate matter, total environmental noise and traffic noise, and distance to and density of greenspace. The intent of the data analysis seeks to understand how social stressors at the neighbourhood level can affect the influence of environmental stressors experienced by individuals. The study will be used as a reference to assist the broader projects for the Canadian Urban Environmental Health Research Consortium (CANUE), ultimately hoping to address healthcare inequality concerns that many are still challenged with.
