I think this is a great message. BMI is a poor indicator of health, and is only marginally correlated with actual quality of life.
Unfortunately, the great irony here is that all of these groups have so far failed to address the use of BMI as a defining indicator in the diagnostic criteria for Anorexia Nervosa. Individuals whose lives may be severely impacted by a serious eating disorder, yet have a normal BMI, are forced into the 'catch-all' diagnostic category of EDNOS (Eating Disorders Not Otherwise Specified). Unfortunately, many insurance companies do not recognize EDNOS as a legitimate illness, and do not provide coverage for it. Research into the category of EDNOS is scarce, due to its heterogeniety, which results from it being a 'dumping-ground' for a multitude of forms of ED.

We support these organizations' statements on BMI, but ask them to also consider the impact of BMI on the people with eating disorders, and the potential for harm that comes from including BMI to define course of treatment and future research.
