More than one-third of children and teens are overweight or obese, resulting in an uptick in the sales and manufacture of larger goods, from school desks to plus-sized children's clothing lines. Gary Foster, director of Temple's Center for Obesity Research and Education, said it's unfortunate that childhood obesity is having such a noticeable impact, but schools do have an obligation to accommodate students of all sizes, large or small. "There's no gain to punishing children for their size. They're already stigmatized," Foster said. "Kids want to belong. They don’t want to be different."
