The mission of the Physical Activity and Epidemiology Laboratory at Queen’s University is to improve the health of Canadians through research, increasing public awareness, and advocacy around issues related to physical activity and obesity.


  • Conducting empirical research on the effects of physical activity, sedentary behaviour, and obesity on morbidity and mortality
  • Surveillance of population trends in physical activity, sedentary behaviour, obesity, and other chronic disease risk factors
  • Quantifying the impact of physical activity, sedentary behaviour, and obesity on population health and the health care system
  • Studying the upstream determinants of physical activity and sedentary behaviour
  • Synthesizing, evaluating and disseminating the existing evidence of the health consequences of physical inactivity, excessive sedentary behaviour, and obesity in the form of scientific reviews and commissioned documents to inform both public health practice and policies aimed at improving the health of the population
  • Training highly qualified graduate students and postdoctoral fellows in the area of physical activity and obesity epidemiology to expand the research capacity in this area in Canada
