The World Health Organization (WHO) Collaborating Centre for Physical Activity, Nutrition and Obesity was established under the auspices of WHO's head office in Geneva to influence policy and public health work on chronic disease prevention globally.

In particular, the centre focuses on physical activity promotion, public health nutrition, obesity prevention and diabetes prevention, and will work in developed and developing countries, as chronic disease is prevalent in most countries across the globe.

The centre is a collaboration between the University of Sydney’s  Prevention Research Collaboration and Boden Initiative with the Charles Perkins Centre.
