The obesity rate of children from poor families is nearly twice as high as that of children from rich families, according to statistics from a Chinese health department. According to government data released in December 2012, more than 24.3 percent of 11-year-olds from poor families were overweight, compared with 13.7 percent of children from affluent families. As a result, experts believe that the poorer the family, the more likely children are to be overweight.
Poor families eat a lot of cheap but high-calorie food best supports the above conclusion.
