In the past few years, the State of Colorado and the American Medical Association reviewed the use of BMI, (Body Mass Index, or perhaps it should be known as Barely Medically Important) as a tool to measure health.
The Colorado legislature implemented a new law.
The AMA adopted a new policy on how BMI should be used as a measure in medicine.
Both instances represent a more thorough understanding of health, eating disorders and medical and mental health issues. And they are both good starts. But as in all things, there are issues.
American Medical Association
In June 2023, the AMA adopted a new policy clarifying the role of BMI as a measure of medicine. Aspects of the policy can be found here:
https://www.ama-assn.org/delivering-care/public-health/ama-use-bmi-alone-imperfect-clinical-measure#
In short, the policy states, “Under the newly adopted policy, the AMA recognizes issues with using BMI as a measurement due to its historical harm, its use for racist exclusion, and because BMI is based primarily on data collected from previous generations of non-Hispanic white populations. Due to significant limitations associated with the widespread use of BMI in clinical settings, the AMA suggests that it be used in conjunction with other valid measures of risk such as, but not limited to, measurements of visceral fat, body adiposity index, body composition, relative fat mass, waist circumference and genetic/metabolic factors. The policy noted that BMI is significantly correlated with the amount of fat mass in the general population but loses predictability when applied on the individual level.”
The AMA also modified existing policy on eating disorders calling on the AMA to:
Encourage training of all school-based physicians, counselors, coaches, trainers, teachers and nurses to recognize abnormal eating behaviors, dieting and weight-restrictive behaviors in children and adolescents and to offer education and appropriate referral of adolescents and their families for evidence-based and culturally informed interventional counseling, and;
Consulting with appropriate, culturally informed educational and counseling materials pertaining to abnormal eating behaviors, dieting and weight-restrictive behaviors.
Interesting and somewhat forward-thinking policies which have been debated for quite some time in the eating disorder community.
The Colorado Law
According to data sourced from the Center for Disease Control, Colorado ranks as the second healthiest state in the United States. Its high ranking is attributed to its active lifestyle culture, abundant outdoor recreational opportunities, and a strong focus on healthy eating. It is also known for having a number of tree hugging, Birkenstock wearing, pot smoking, hippie libruls. [I kind of respect that last aspect.]
With its liberal politics and lifestyle and focus on health, it should come as no surprise that Colorado politicians wanted to do away with the much criticized BMI as an indicator of health. And so, the Colorado legislature passed a bill which greatly limited the use of BMI
This bill can be found here:
If you can work your way through this bill and then reach a place of partial understanding, there is much to embrace. And much which provides confusion.
On the one hand, the some of the substance of the bill states, “… SHALL NOT UTILIZE THE BODY MASS INDEX, IDEAL BODY WEIGHT, OR ANY OTHER STANDARD REQUIRING AN ACHIEVED WEIGHT WHEN DETERMINING MEDICAL NECESSITY OR THE APPROPRIATE LEVEL OF CARE FOR AN INDIVIDUAL DIAGNOSED WITH AN EATING DISORDER, INCLUDING BUT NOT LIMITED TO BULIMIA NERVOSA, ATYPICAL ANOREXIA NERVOSA, BINGE-EATING DISORDER, AVOIDANT RESTRICTIVE FOOD INTAKE DISORDER, AND OTHER SPECIFIED FEEDING AND EATING DISORDERS AS DEFINED IN THE MOST RECENT EDITION OF THE DIAGNOSTIC AND STATISTICAL MANUAL OF MENTAL DISORDERS.
But then, the next part of the bill states, “SUBSECTION (1)(a) OF THIS SECTION DOES NOT APPLY WHEN DETERMINING MEDICAL NECESSITY OR THE APPROPRIATE LEVEL OF CARE FOR AN INDIVIDUAL DIAGNOSED WITH ANOREXIA NERVOSA, RESTRICTING SUBTYPE, OR BINGE-EATING/PURGING SUBTYPE; HOWEVER, BODY MASS INDEX, IDEAL BODY WEIGHT, OR ANY OTHER STANDARD REQUIRING AN ACHIEVED BODY WEIGHT MUST NOT BE THE DETERMINING FACTOR WHEN ASSESSING MEDICAL NECESSITY OR THE APPROPRIATE LEVEL OF CARE FOR AN INDIVIDUAL DIAGNOSED WITH ANOREXIA NERVOSA, RESTRICTING SUBTYPE, OR BINGE-EATING/PURGING SUBTYPE.”
Ok, so I am a reasonably intelligent human being. But, what in the blue hell does the language of the bill mean? On the one hand, BMI, ideal body weight or any other standard requiring an achieved weight can only be applied to anorexia nervosa – restricting subtype and binge-eating/purging subtype so long as they are not the determining factor? Well, that doesn’t seem too vague, confusing and subject to interpretation!
It would also appear as if the bill, albeit well intentioned is having adverse effects. Dr. Elizabeth Wassenaar, the Regional Medical Director for the Mountain and West regions at Eating Recovery Center and Pathlight Mood & Anxiety Center was interviewed by an NBC news local affiliate. This interview can be found here:
In the interview, Dr. Wassenaar stated:
“On face value, I 100% agree with this legislation,” Wassenaar said. “I absolutely want to see every person who needs eating disorder treatment be able to access it. And I never want to see someone be discriminated against because of the size of their body, especially when it comes to receiving care for their eating disorder.”
“Unfortunately, what we are seeing is that patients who are in small bodies who are malnourished are actually being excluded from care or being asked to step down before they are ready because we can’t consider their degree of malnutrition as a part of their degree of severity of illness.”
“And the reality is when you have a statute that makes this sort of determination, then it takes the decision out of the hands of the medical providers who are taking care of people with these patients.”
Indeed.
Which brings up the seminal question …
The Question
With BMI being an incredibly troubling issue regarding its use (or non-use) with eating disorders, why hasn’t a definitive policy or statement been released from experts in the eating disorder community? A unified, collaborative statement so strong, so authoritative, that legislatures, organizations and health insurance providers alike adopt it as THE definitive word on BMI.
After all, the research, study and treatment of eating disorders are the raison d’être for our experts’ existence.
Shouldn’t the continued existence of BMI, or the genesis of its demise lie with the recognized experts in the eating disorder community? Those who study it and either use it or decry it as a diagnostic tool.
Envision if you will, some of the most renowned experts worldwide in the field of eating disorders coming together to brainstorm, to share research and ideas. And then issuing a comprehensive study supported by all of the eating disorder organizations and treatment entities. Including representatives from the health insurance industry.
If ever a time existed for this wisdom, this type of collaboration, this coming together as one, that time is now.
And so, the last question is … who is going to step to the plate and turn this into a reality?
