EOSS: Time To Drop Stage 0?

Readers will be well aware of the Edmonton Obesity Staging System (EOSS), which classifies the severity of obesity on a five-point ordinal scale based on presence of medical, mental, and/or functional health issues related to excess weight.

By design, EOSS considers Stage 0 in individuals, who meet the BMI criteria for obesity but do not have any apparent health issues.

However, given the recent change in definition of obesity expressed in the newly released Canadian Adult Obesity Clinical Practice Guidelines, obesity is defined as, “the presence of excess or abnormal body fat that impairs health”, BMI should no longer be used as the defining characteristic of obesity.

Thus, one would not consider someone who has no health impairments, irrespective of BMI, to have obesity.

As a result, the EOSS stage 0 no longer makes sense, as this individual, by definition, would no longer meet the key criterion for obesity, namely an impairment in health (perhaps one may consider the term “pre-obesity” in this context?).

This also means that it is now time to abandon the term “healthy obesity” – either you have obesity, meaning you have a health impairment attributable to excess body fat, or you simply do not have obesity!

In practice, you need to be able to list exactly what weight-related health impairments a given person has before labelling them as having obesity.

If you cannot specifically list the health impairments (at least possibly) attributable to excess body fat, then that individuals, irrespective of BMI, does no longer meets the diagnostic criteria for obesity.

This seismic change in how we apply the term “obesity” to a clinical diagnosis will take time to implement and be adopted. No doubt, many will long back for simpler times, where you could just step on a scale, plug the numbers into a BMI calculator, and make a diagnosis based on tables or charts.

It will be interesting to see how long it will take for this new definition to be widely adopted in policy and practice.

From Blog Posts To Guidelines

Yesterday saw the release of the long-awaited Canadian Adult Obesity Clinical Practice Guidelines.

Getting to these guidelines was a long journey, that started well before the decision, about three years ago, to begin the daunting task of assembling the steering committee, the chapter authors, the literature review, the crafting of recommendations, the rating of recommendations, preparing the publication and the actual launch.

Looking back, I realise that many of the so-called “novel” concepts included in the guidelines, stem back to topics and ideas about obesity, its nature, its causes, and management that I have thought about and discussed on this blog almost a decade ago.

To illustrate this thought process, I have provided links to some of my previous posts on topics which have now found their way into the guidelines.

They certainly make for some interesting reading:

October 2007: Why I Don’t Like BMI

March 2008: Obesity Classification: Time to Move Beyond BMI?

April 2008: Recognising Barriers Key to Obesity Management?

August 2008: Obesity is a Sign, Overeating is a Symptom

February 2009: Edmonton Obesity Staging System

October 2009: Do Mental Health Problems Predict Obesity?

Novermber 2009: The M & Ms of Obesity Assessment

August 2011: Weight Loss is Not a Goal

September 2011: The 5 As Approach To Obesity Counseling

It is indeed humbling to realise just how many of these ideas, first discussed in these decade-old blog posts, are now reflected in the new CPGs.

The Canadian Obesity Guidelines Are Here – Time To Join The Conversation!

As of this morning, the 2020 Canadian Clinical Practice Guidelines for Obesity Management in Adults are out on the CMAJ and Obesity Canada websites, respectively.

These guidelines present a departure from previous guidelines on a number of important issues.

For one, Obesity is clearly defined as “a prevalent, complex, progressive and relapsing chronic disease, characterized by abnormal or excessive body fat (adiposity), that impairs health.”

Although BMI and waist circumference can still be used for populations surveillance and screening purposes, the ultimate diagnosis should be based on the impact that adiposity has on health and not some arbitrary anthropometric cutoffs.

Other topics that receive strong consideration include the role of weight bias in clinical practice, a departure from solely weight-centric outcome with a focus on health and wellbeing, learning from the body positivity movement, recognising the importance of root causes including psychosocial factors and mental health, and much more.

Given that there will be many questions and issues around many of these topics, especially with regard to implementation in practice, Obesity Canada is also launching an online information and discussion platform OC-Connect-Pro, where health professionals can connect and share information, tap into tools and education about the guidelines.

Early Registration For Obesity Guideline Webinars Now Open

We are now just one day from the long-anticipated release of the 2020 Canadian Obesity Clinical Practice Guidelines in the Canadian Medical Association Journal (CMAJ) and on the Obesity Canada website.

But, registration for a first series of six webinars, starting Aug 11, by some of the leading chapter authors is already open. This interactive webinar series is offered through a partnership between Obesity Canada and the University of Alberta’s Office of Lifelong Learning.

For a nominal fee of just $50 (Canadian) for all six webinars (i.e. less than $10 per webinar), participants will be able to:

  1. Provide obesity chronic disease management in a planned, proactive manner
  2. Support patients to understand how their root causes, comorbidities and personal context are related to their obesity management
  3. List, review and select therapeutic approaches (behavioural, medical, surgical) to help patients develop personalized plans to manage their obesity as a chronic disease.

Speakers include Drs. Sean Wharton (Toronto), Sara Kirk (Halifax), Michael Vallis (Halifax), Sue Pedersen (Calgary), Rita Hendersen (Calgary), and myself.

The 2020 Canadian Obesity Guidelines for Adults are Coming!

Finally, after about three years of hard work by a panel of over 60 authors (not to mention the incredible staff at Obesity Canada), the 2020 Canadian Clinical Practice Guidelines for Obesity Management in Adults will be released in the Canadian Medical Association Journal next week (Aug 4).

This monumental undertaking, that began with extensive literature searches (identifying over 550,000 potentially relevant articles), which was systematically whittled down to about 80 GRADEd recommendations, represents a state-of-the-art evidence and practice informed overview of managing obesity as a complex progressive chronic disease.

Without divulging too much, I can share that the guidelines will cover a broad range of topics from re-defining obesity, to the importance of recognizing weight bias in obesity medicine, to taking a patient-centred approach, where the focus is on improving health and well-being rather than just changing numbers on the scale.

Importantly these guidelines are perhaps unique in the field of obesity, as they include analyses of both quantitative and qualitative research, the latter having often being largely ignored by previous guidelines. In addition, there was ample involvement and representation of the patient voice in the discussion of findings and wording of recommendations.

Targeted at primary care practitioners, the guidelines outline what we know about obesity management but also outlines the often extensive and important gaps in our knowledge.

So please stay tuned, as more information becomes available over the next few days and weeks.
