The School Health Action, Planning and Evaluation System (SHAPES) is a study that monitors health-related behaviours among youth in several health unit areas across Ontario. It was developed by the Population Health Research Group at the University of Waterloo.
All English Public and Catholic school boards within the jurisdiction of the Simcoe Muskoka District Health Unit were eligible to participate in the SHAPES study. Twenty-eight high schools were approached to participate and 26 agreed, for a response rate of 93%.
Data collection was conducted from September 2005 to May 2006. Classes within each grade were randomly assigned to complete either the SHAPES-Smoking Behaviours questionnaire or the SHAPES-Physical Activity questionnaire. Of the 27,175 eligible students, 20,567 completed the questionnaires, for a student response rate of 74.4%.
