The World Health Organization says excessive weight, obesity, aging and population growth drove a nearly fourfold increase in worldwide cases of diabetes over the last quarter-century, affecting 422 million people in 2014.
The U.N. health agency is calling for stepped-up measures to reduce risk factors for diabetes and improve treatment and care.
On Wednesday, WHO Director-General Margaret Chan said: "We need to rethink our daily lives: to eat healthily, be physically active and avoid excessive weight gain."
U.S. & World
WHO reported that 8.5 percent of the world population had diabetes two years ago, up from 108 million, or 4.7 percent, in 1980.
The Geneva-based agency blamed the growing consumption of food and beverages high in sugar. Diabetes grew around the world, but increased most in Africa, the Middle East and Asia.
