Background

Obesity is a major concern for the Hispanic population (81% of the adult population is obese). One of the most efficacious mechanisms for weight loss and to reduce the risk of obesity-related complications is the Sleeve Gastrectomy (SG). Weight loss and improvements in metabolic outcomes are common features follow SG. What is not known is how SG impacts eating behavior. Therefore, the aim of this study is to analyze the postoperative psychometric and behavioral changes on response to food questioners before and 6 months after SG in Hispanic females (HF).

Methods

The Eating Attitude Test (EAT) and Power of Food Scale (POF) were completed before SG and 6 months after. The EAT measures symptoms characteristic of disordered eating while POF is a psychometric evaluation to measure appetite and asses the psychological impact of living in a food abundant environment.

Results

10 HF (30-48) participated in the study. The individual responded to the surveys before and after SG. Significant behavioral modifications were observed 6 months after surgery. Specifically, reductions in concerns associated with body weight, reductions in ‘guilty’ associated with eating, and healthier eating habits were noted following SG. Survey responses were correlated with brain function as obtained by Independent Component Analysis Methods.

Conclusions

Our results indicate there are benefits of SG in HF which altered their relationship with food intake, their body habitus, which was correlated with changes in resting state functional Magnetic Resonance Imaging.
