Physical activity and nutrition are modifiable risk factors which are significant contributors to the development of disease in both developed and developing countries. In high income countries, the effects of sedentary behaviours and over-nutrition have resulted in large increases in the prevalence of non-communicable disease (NCD). However, the changes in NCD burden is not uniform with major declines in premature cardiovascular mortality in the face of rising obesity and type 2 diabetes. In low and middle income countries, poor nutrition can contribute to childhood and maternal mortality. However, economic development in low and middle income countries has resulted in increasing obesity and NCD mortality rates.

This course provides an overview of the changing nature of disease burdens in different population settings and the role physical activity and nutrition have to play. The course will examine the contextual factors that influence the success or failure of population-based physical activity and nutrition interventions. Successful completion of the course will enable students to develop skills in critiquing interventions and policies that aim to change population risk factors, a critical competency needed to engage in public health practice.
