Pre- and Postbariatric Subtypes and Their Predictive Value for Health-Related Outcomes Measured 3 Years After Surgery.

Background: Although bariatric surgery is the most effective treatment for severe obesity, a subgroup of patients shows insufficient postbariatric outcomes. Differences may at least in part result from heterogeneous patient profiles regarding reactive and regulative temperament, emotion dysregulation, and disinhibited eating. This study aims to subtype patients based on these aspects before and 2 years after bariatric surgery and tests the predictive value of identified subtypes for health-related outcomes 3 years after surgery.

Identifying prebariatric subtypes based on temperament traits, emotion dysregulation, and disinhibited eating: A latent profile analysis.

Objective: The efficacy of bariatric surgery has been proven; however, a subset of patients fails to achieve expected long-term weight loss postoperatively. As differences in surgery outcome may be influenced by heterogeneous psychological profiles in prebariatric patients, previous subtyping models differentiated patients based on temperament traits. The objective of this study was to expand these models by additionally considering emotion dysregulation and disinhibited eating behaviors for subtyping, as these factors were associated with maladaptive eating behaviors and poor postbariatric weight loss outcome.

Weight bias internalization, emotion dysregulation, and non-normative eating behaviors in prebariatric patients.

Objective: Weight bias internalization (WBI) is associated with eating disorder psychopathology and non-normative eating behaviors among individuals with overweight and obesity, but has rarely been investigated in prebariatric patients. Based on findings demonstrating a relationship between emotion dysregulation and eating behavior, this study sought to investigate the association between WBI and eating disorder psychopathology as well as non-normative eating behaviors (i.e.

Nonnormative eating behavior and psychopathology in prebariatric patients with binge-eating disorder and night eating syndrome.

Background: Binge-eating disorder (BED) as a distinct eating disorder category and night eating syndrome (NES) as a form of Other Specified Feeding or Eating Disorders were recently included in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This study sought to investigate the prevalence of BED and NES and associations with various forms of nonnormative eating behavior and psychopathology in prebariatric patients. Within a consecutive multicenter registry study, patients in 6 bariatric surgery centers in Germany were recruited.

Influences of general self-efficacy and weight bias internalization on physical activity in bariatric surgery candidates.

Background: Physical activity (PA) seems to be important for long-term weight loss after bariatric surgery; however, studies provide evidence for insufficient PA levels in bariatric patients. Research found self-efficacy to be associated with PA and weight bias internalization, for which an influence on mental and physical health has been shown in recent studies. The purpose of the present study was to investigate the influence of general self-efficacy on PA, mediated by weight bias internalization.

Patient expectations of bariatric surgery are gender specific--a prospective, multicenter cohort study.

Background: The effect of bariatric surgery on weight loss and improvement of co-morbidities is no longer doubted. However, little attention has been given to the treatment goals from the patient's point of view (patient expectations). The objective of this study was to examine patients' expectations of bariatric surgery and identify gender differences.

Status of bariatric surgery in Germany--results of the nationwide survey on bariatric surgery 2005-2007.

Background: Most studies on bariatric surgery outcomes are performed as clinical trials or reflect the clinical experience in single centers. The status of bariatric surgery in Germany has been examined with the cooperation of clinics and hospitals at the Institute of Quality Assurance in Surgery at the Ottovon-Guericke University of Magdeburg (Germany) since January 1, 2005.

Methods: In this prospective multicenter observational study, the data obtained for all primary bariatric procedures, including all repeated operations, performed on consecutive patients with morbid obesity at participating hospitals from 2005 to 2007 were prospectively collected using an internet online data registry.
