1.1 Wind Turbine Health Studies: Epidemiological study and GIS analysis
As previously reported, the RETH survey was sent to 5000 homes across eight Ontario communities with wind generation facilities (the counties of Bruce, Dufferin, Elgin, Essex, Frontenac, Huron, Norfolk, and Chatham-Kent) in January, 2013. Homes within 5km of the selected wind farms received a survey and, later, an invitation to participate in the same survey online if they had yet to participate. The survey included sections focussing on health, sleep, environmental stressors, housing and community, and perceptions of wind. Analysis and publication of survey data is still ongoing. Results from the sleep and health sections are now available and are being prepared for submission to peer-reviewed journals. Results from other sections of the survey (perceptions, environmental stressors, health) have beenpresented at conferences and preliminary results are discussed here.
Sleep and Health
Results from the survey could suggest that there is a possible association between various health outcomes and how far someone lives from an industrial wind turbine. A cross-sectional study involving eight Ontario communities that contain greater than ten industrial wind turbines were selected for study. The ‘Quality of Life and Renewable Energy Technologies Study’ survey was sent to 4,876 residences near industrial wind turbines in these eight communities. Descriptive analyses were performed and multiple regression models were run to investigate the effect of the main independent variable of interest (distance to nearest industrial wind turbine) on the various outcome variables. Descriptive statistics, including means and standard deviations were performed on a number of dependent and independent variables including age, sex, time in home, number of industrial wind turbines within 2,000 meters and sleep and health outcomes.Read article
