This paper presents the results of a multidisciplinary expert workshop to identify current knowledge and more importantly current gaps in knowledge on the epidemiological and biopsychosocial determinants of obesity and its optimal treatment approaches.

Childhood obesity is a global medical and public health threat with high prevalence rates leading to numerous health problems and comorbidities (1). While in many countries there is a plateauing in the rise of obesity rates (2, 3), a continuous rise in the rate of extreme obesity can still be noted (4). This is of special concern as extreme obesity is an intractable disease (5) associated with multiple comorbidities (6, 7).

In line with the current Endocrine Society guidelines (2), the authors recommend lifestyle intervention as the primary therapy, even though most studies showed limited or no success for most adolescents with extreme obesity (8). Concerning pharmacotherapy and weight-reducing devices, the authors point out the limited data in the pediatric population especially concerning long-term safety and efficacy. Even for bariatric surgery, which has been studied in well-designed studies in this population and is by far most effective treatment with an average weight loss of 30% (9, 10), very-long-term data are still scarce. In addition, although responses to most weight loss interventions are overall small, they vary widely between individuals.

Therefore the authors call for a standardization of measures of obesity and treatment outcomes to make (intervention) studies more comparable. This starts with the establishment of valid and accepted BMI metrics. The authors also promote the “Accumulating Data to Optimally Predict Obesity Treatment” (ADOPT) project (11) which aims to create common processes and measures for obesity research. So far, identified determinants of body weight explain only a small proportion of variations in weight status. Therefore, the authors conclude that it is necessary to develop an integrated model to allow the identification of different biopsychosocial phenotypes that predict treatment responses and will provide the basis for patient-tailored novel treatments.

In summary, this article provides an excellent lecture for clinical researchers in childhood obesity, guiding toward precision medicine approaches to treat severe obesity in adolescents. The article also defines area for future research and encourages the development of comparable and reproducible data in this challenging field of medicine.
