The IUHPE collaborates with the World Health Organization (WHO) and the CDC on how to best implement the WHO Global Strategy on Diet, Physical Activity & Health, as well as the broader agenda of developing public health action for physical activity and preventing non-communicable diseases. Non-governmental organisations (NGO), like the IUHPE and its collaborating networks, can play a central role in supporting physical activity promotion, addressing the challenges to promote physical activity and overcome barriers to action in countries and regions at varying levels of economic development.
