This course examines the field of population health sciences. Starting with a review of the concepts of Geoffrey Rose, students will examine foundational theories and methods used in population health studies. Through course assignments and discussion, students will critically appraise these concepts, as well as the various factors that shape population health and the fundamentals of prevention science at both the individual and population level. This course will also focus on the constitutive importance of health equity in theories of population health sciences. This will enable equitable health promotion and governance, and identifying contextual factors that influence health equity deliberations in contemporary approaches to public health practice. Students will further explore the future of this discipline and the importance of what Keyes & Galea describe as humility in population health sciences.
