Very little progress has been made in reducing levels of inactivity worldwide, experts have warned.
A WHO report estimates that more than a quarter of people worldwide – 1.4 billion – are not doing enough physical exercise, a figure that has barely improved since 2001.
Inactivity raises the risk of a raft of health problems, such as heart disease, type-2 diabetes and some cancers.
High-income countries, including the UK, were among the least active.
And women were found to be more sedentary throughout the world, with the exception of two regions of Asia.
