Country sees big spike in kids' weight

Too many calories, too little exercise - effects of prosperity - blamed for unhealthy trend

Experts are calling for healthier lifestyles to avoid the risks of obesity, on the heels of a report showing that millions of children in China are overweight.

More than 5.8 million children under age 5 are too heavy, accounting for 7 percent of the total population of the age group, according to a global nutrition report released by the Global Alliance for Improved Nutrition, an international organization that was launched at the United Nations in 2002 to tackle malnutrition.
