BC CLEAR Projects 2015-2016 (funding start dates) > Investigating Air Pollution as a Risk Factor for Autism: A Population-Based Analysis for BC posted on 7:31 PM, July 6, 2016
Project leader: Meghan Winters This project examined the impact of air quality in BC with the development of autism or autism spectrum disorder (ASD). This project was a population-based analysis of children diagnosed with ASD in the public health system in BC from 2004–2014, to calculate air pollutants NO2, SO2, PM2.5, and CO exposure estimates of mothers, and to test the associations between air pollutant exposure during fetal development with the development of autism. Project researchers conducted a spatial analysis of autism diagnoses overlaid with air pollution data to identify spatial patterns, observe trends over time, and visualize the association between air pollution levels and autism cases. The mean residential exposure estimates was used to calculate the odds for the development of ASD associated with NO2, SO2, PM2.5, and CO exposure during prenatal development. Lastly, the project produced interactive maps of the spatiotemporal distributions of air pollutants and autism diagnoses from 2000–2014 for Metro Vancouver.
