New Obesity Definition and Clinical Obesity Prevalence for Global Metabolic Bariatric Surgery

This international, multicenter cross-sectional study found that the majority of MBS candidates met criteria for clinical obesity, while a substantial minority were classified as having preclinical obesity.
