This course focuses on the central role of physical activity in combination with other lifestyle choices including nutrition, substance use, sexual practices, the use of health care services, and so on in determining health. The inter-relationships among lifestyle choices and between them and the most common major health disorders are explored, with consideration of the social context in which these choices are made. In addition to physical activity, sedentarism and fitness, topics covered include: nutrition; immunity and infectious disease; substance use and abuse; cardiovascular diseases; cancer; mental health and disorders; sleep; trauma; environmental health and health care/self-care practices. The course will use students’ lifestyles on and off campus as examples of ways in which physical activity and other determinants of health are affected by personal choices; this includes consideration of the many formal and informal opportunities for physical activity that exist on campus.
