Researchers are also zeroing in on genes and environmental factors associated with eating disorders. Striegel-Moore found similar rates of extreme behaviors (like vomiting) in more-affluent blacks and whites, suggesting that higher social status–and the pressure to be thin that comes along with it–could lead to more problems. Overall, eating disorders are rare among all races and ethnicities, but obesity is out of control. We need to be on the lookout for both.
