      The European Association for the Study of Obesity presents a new framework for the diagnosis, staging and management of obesity in adults to better align with the concept of obesity as an adiposity-based chronic disease.

      Obesity is a multifactorial, chronic, relapsing, non-communicable disease marked by an abnormal and/or excessive accumulation of body fat that presents a risk to health. It is well established that obesity acts as a gateway to a range of other non-communicable and communicable diseases1–3 .

      Despite this wide recognition of obesity as a chronic disease, the clinical recommendations that guide the diagnosis of obesity and its management have not been aligned sufficiently with the clinical processes normally adopted for other chronic diseases. In many settings, the diagnosis of obesity is still based solely on body mass index (BMI) cut-off values, and does not reflect the role of adipose tissue distribution and function in the severity of the disease1 . Moreover, the indications for using the different therapeutic approaches now available for obesity management remain mostly based on anthropometric measurements, rather than on a more complete clinical evaluation of the individual4 . This is in sharp contrast with other chronic diseases, for which clear therapeutic indications are described, targets are set, and the choice of the type and intensity of treatment is based on the probability of reaching the treatment target, with adequate and prompt treatment intensification when the target is not reached.

     To stimulate the development and implementation of clinical guidelines for obesity that are more aligned with those already in place for other chronic diseases, the European Association for the Study of Obesity (EASO) initiated and conducted a consensus process to propose a new framework for the diagnosis, staging and management of obesity in adults.

Consensus process

      We performed a modified Delphi study5,6 to identify a set of statements that can aid in the diagnosis, staging and management of obesity according to a framework that is more adherent to the concept of obesity as an adiposity-based chronic disease (ABCD)1 . A steering committee identified by the EASO, consisting of the authors of this paper, discussed and prepared an initial set of statements used for a voting process by a group of experts. Voting was performed on a five-point scale, as follows: (1) strongly disagree; (2) disagree; (3) neither agree nor disagree; (4) agree; and (5) strongly agree. In each round of voting, experts were also asked to provide comments to explain their voting score, and responses were anonymized. The steering committee evaluated the voting and comments received at each  round and generated a modified set of statements for the subsequent round of voting. Consensus was defined as ≥75% of expert agreement on a statement (score ≥4).

     The steering committee retained responsibility for the selection of experts involved in the process. Selection was based on international reputation and known expertise in obesity science and management.

     In total, 29 experts were contacted, and all agreed to participate in the present study. Most of the experts belong to the endocrinology, nutrition or internal medicine fields (72%), but the group also included five bariatric surgeons, two primary care physicians and one expert on patient advocacy. A standard conflict of interest form was completed by each participant before the start of the Delphi process. This study was performed by the EASO without any external funding, and approval by the ethics committee was not required.

      The study comprised three Delphi rounds. In the first round, 25 experts (86%) voted and commented on 30 original statements that were prepared by the steering committee. A total of 21 statements (70%) received consensus. The steering committee evaluated voting and comments and generated a second set of 28 statements submitted for a second Delphi round. In the second round, 24 experts (83%) voted and commented on the statements. A total of 24 statements (86%) received consensus. The steering committee discussed the comments received for the four non-consented statements, reconsidered the formulations of these statements, and submitted the four revised statements for the final Delphi round. In the third round, 24 experts (83%) voted and provided final comments related to the four revised statements. One of these four statements (statement 12) reached full consensus, whereas most experts approved the other three revised statements (statements 3–5), with only a few experts providing a score <3 (that is, strongly disagree or disagree). The steering committee performed a final revision and decided to approve a list of 28 statements, covering clinical diagnosis and staging of obesity, pillars of treatment, therapeutic targets, and initial level of intervention. The final list of statements and final percentages of approval by the experts is shown in Table 1. A flowchart of the diagnostic and therapeutic pathways resulting from the statements is presented in Fig. 1.

A chronic progressive disease

      The recognition of obesity as a complex chronic non-communicable disease should inform the development of evidence-based guidelines for the diagnosis and management of obesity. We anticipate that, in conjunction with other ongoing initiatives7 , this Delphi process will contribute to improving obesity management in adults living with obesity.

      Based on current clinical evidence, the diagnosis of obesity should not be based solely on the presence of an abnormal and/or excessive fat accumulation (anthropometric component). The diagnosis of obesity should instead include a careful analysis of the present and potential effects that dysfunctional and/or excessive fat accumulation may have on health (clinical component) (statement 1). This statement aligns with what has been suggested by other recent guidelines on obesity management8,9 . Moreover, this statement fully adheres to the concept that obesity should be considered a chronic progressive disease process that may transit from a relatively asymptomatic state to a phase in which abnormal and/or excessive fat accumulation is accompanied by health impairments, and finally to a life-threatening or disabling condition10.

Abdominal fat accumulation

      An important novelty of our framework regards the anthropometric component of the diagnosis. The basis for this change is the recognition that BMI alone is insufficient as a diagnostic criterion, and that body fat distribution has a substantial effect on health. More specifically, the accumulation of abdominal fat is associated with an increased risk of developing cardiometabolic complications and is a stronger determinant of disease development than BMI, even in individuals with a BMI level below the standard cut-off values for obesity diagnosis11. This is reflected by two important statements. First, we make explicit that abdominal (visceral) fat accumulation is an important risk factor for health deterioration, also in people with low BMI and still free of overt clinical manifestations (statement 3). Second, the new framework includes people with lower BMI (≥25–30kg/m2 ) but increased abdominal fat accumulation and the presence of any medical, functional or psychological impairments of complications in the definition of obesity, hence reducing the risk of undertreatment in this particular group of patients in comparison to the current BMI-based definition of obesity (statement 4). The choice of introducing waist-to-height ratio, instead of waist circumference, in the diagnostic process is due to its superiority as a cardiometabolic disease risk marker12.

Diagnostics and staging

      The clinical component of the diagnosis should include a systematic evaluation of medical, functional and psychological (such as mental health and eating behavior pathology) impairments in any person with obesity, as also suggested in other guidelines8,9 . A detailed description of the clinical aspects and methodologies that need to be included in this systemic clinical evaluation was beyond the scope of this exercise. For the medical evaluation (statement 9), several documents are available to provide guidance4,8 . For the functional and psychological evaluation, examination may be performed using an array of methods, ranging from easy-to-perform tests that are applicable in the primary care setting to more sophisticated tests, which may be reserved for specialized centers (statements 10 and 13). Considering the emerging problem of obesity in older individuals, statement 11 was included to emphasize the importance of performing a diagnostic assessment (muscle strength, performance and body composition) for sarcopenic obesity13. Finally, considering the strong association between obesity and several types of cancer, a statement calling for regular screening for obesity-related cancers in any person with obesity was included (statement 12).

      Clinical staging processes are frequently used to evaluate and describe an individual’s health status and the progression of chronic diseases. Clinical staging usually expresses the severity of a disease in a simplified, condensed and standardized way. This has prognostic implications, and it may guide or mandate therapeutic interventions. In our Delphi process, the experts agreed on the importance of staging obesity as a chronic, relapsing disease, according to the severity of its clinical manifestations and complications (statement 14), as proposed by previous guidelines9 .

Obesity management

      Considering the pillars of treatment of people with obesity (statements 15–21), our recommendations substantially adhere to current available guidelines4,8,9 . Behavioral modifications, including nutritional therapy, physical activity, stress reduction and sleep improvement, were agreed as main cornerstones of obesity management, with the possible addition of psychological therapy, obesity medications and metabolic or bariatric (surgical and endoscopic) procedures. For the latter two options, the steering committee discussed the fact that current guidelines are based on clinical evidence derived from clinical trials, in which inclusion criteria were mostly based on anthropometric cut-off values rather than on a complete clinical evaluation4,8,9,14. In current practice, the strict application of these evidence-based criteria precludes the use of obesity medications or metabolic/bariatric procedures in patients with a substantial burden of obesity disease, but low BMI values. Therefore, members of the steering committee proposed, and experts subsequently agreed (79%), that, in particular, the use of obesity medications should be considered in patients with BMI ≥ 25 kg/m2 and a waist-to-height ratio > 0.5 and the presence of medical, functional or psychological impairments or complications, independently from current BMI cut-off values (statement 18). This statement may also be seen as a call to pharmacological companies and regulatory authorities to use inclusion criteria that are more adherent to the clinical staging of obesity and less to traditional BMI cut-offs when designing future clinical trials with obesity medications15.

      Full agreement among the experts was reached for the statement that the management of obesity should move beyond weight loss alone, and should include the prevention, resolution or improvement of obesity-related complications, a better quality of life and mental wellbeing, and improvement of physical and social functioning and fitness (statement 22). This statement will move obesity management closer to the management of other non-communicable chronic diseases, in which the goal is not represented by short-term intermediate outcomes, but by long-term health benefits. Defining long-term personalized therapeutic goals should inform the discussion with the patients from the beginning of the treatment, considering the stage and severity of the disease, the available therapeutic options and possible concomitant side effects and risks, patient preferences, individual drivers of obesity and possible barriers to treatment (statements 23 and 24). Emphasis on the need for a long-term or life-long comprehensive treatment plan rather than short-term body weight reduction is warranted.

      The concept of obesity as a chronic disease and the discussion of therapeutic targets should also inform the choice of the initial level of intervention and eventual intensification of therapy (statements 26–28), avoiding the same repetitive and futile cycles of intervention that are not effective enough to achieve patient benefit, and preventing therapeutic inertia16.

      This Delphi process represents the current vision of the EASO on the diagnosis, staging and management of obesity as a complex, relapsing, non-communicable chronic disease in adults. We anticipate that the recommendations outlined in this paper, in conjunction with other ongoing international initiatives7 , will contribute to improved obesity management strategies that are more consistent with treatment algorithms already applied for other non-communicable chronic diseases. Moreover, this framework may aid scientific advancements and the development of new clinical practice guidelines.
