Although weight issues plague Americans as gravely as anywhere on the planet, obesity also has become a global woe, increasing sharply over the last three decades in 195 countries and afflicting an estimated 604 million adults and 108 million children—roughly 10 percent of the world’s population.
No nation on earth, even with the terrible toll that obesity takes in economic and health terms, has found a way to get its people skinnier and healthier: Weight woes are blowing up in disparate places like Saudi Arabia, Algeria, Egypt, Burkina Faso, Mali, and Guinea-Bissau, international researchers have reported in the New England Journal of Medicine. Obesity is now a major concern, too, for the people of China, Turkey, Venezuela, and Bhutan.
Public health experts worry about the skyrocketing numbers of overweight people around the planet because evidence shows obesity to be a major factor in heart disease, diabetes, cancer, and other debilitating conditions. These afflictions, combined with weight issues—including among those considered to be too heavy but not necessarily obese—contributed to four million deaths in 2015 alone, said the experts, participating as part of the Global Burden of Disease initiative.
