Abstract

Objective: The study objective was to empirically identify subgroups of patients with obesity and investigate their association with postoperative weight change. Methods: A longitudinal analysis of 2,458 adults in the Longitudinal Assessment of Bariatric Surgery (LABS) study was used. Baseline data were used to identify subgroups. The outcome was 3-year weight change after bariatric surgery. Results: We identified four classes (subtypes) of obesity, which could be characterized as diabetes with low rates of high-density lipoprotein (Class 1), disordered eating (Class 2), mixed (Class 3), and extreme obesity with early onset (Class 4). Approximately 98% of participants in Class 1 had diabetes compared with < 40% in the other classes. There were high rates of binge eating in Class 2, and more than 92% of those in this class reported eating when not hungry. Class 4 was characterized by a higher BMI at baseline. Adults in Class 4 lost an average of 25.0% (males) and 30.3% (females) of their baseline weight over 3 years. In contrast with participants in Class 1, those in Classes 2 and 3 had significantly larger 3-year weight losses than their peers in Class 4. Conclusions: Obesity is a heterogeneous disease. Bariatric surgery may be most beneficial for adults with disordered eating.
