Dr. Spence has expertise in the area of behavioural medicine and research methods. His research focuses on both the benefits and determinants of physical activity and how physical inactivity is related to obesity. Dr. Spence has studied the broad social determinants (e.g., SES) and population physical activity patterns. More recently, he has focused on (a) the physical environment and how it may influence physical activity choices and risk for obesity among both children and adults (e.g., urban form, location of food establishments), and (b) the effect of media (e.g., popular films) on physical activity and diet. Dr. Spence has a strong background in physical activity measurement, meta-analysis, and ecological models of behaviour and health. His work is funded by the Canadian Institutes of Health Research (CIHR), Heart & Stroke Foundation of Canada (HSFC), Social Sciences and Humanities Research Council (SSHRC), and the Alberta Heritage Foundation for Medical Research (AHFMR).
