Kids from low-income families are more likely to be obese than wealthier children, research suggests. But the relationship is complex, and scientists are still trying to untangle the links between income and such factors as diet and exercise that contribute to obesity.
New data make those connections even more complicated. Low-income kids—from households earning less than $31,500 for a family of four—got about the same percentage of their calories from fast food as wealthier kids, according to a federal survey of more than 5,000 people, including children of all ages, from the Centers for Disease Control (CDC).
