The role of schools of public health: learning from history, looking to the future.

There is a broad consensus on the need for high-quality public health education and research to tackle the world's many public health challenges. Public health education and research are delivered by a variety of institutions operating very different models, which collectively can be called schools of public health. Given the importance of education and research to public health systems, it is surprising how little research has been done to assess the role of schools of public health in contributing to population health. In particular, it is notable there has been very little research on the strengths and weaknesses of the different models of schools of public health that have evolved over the last 100 years. Thus, a historical perspective is crucial. To date most historical work has focused on US schools of public health. Although the evidence is patchy, a global overview of the history of schools of public health identifies three important themes: capacity building, multidisciplinarity and balancing teaching and research. Newer challenges and opportunities include addressing the impact of climate change and developments in e-learning. Schools of public health have the potential to make a central contribution to progress in public health practice in the twenty-first century.
