Eating behavior and physical activity behavior are under the control of certain cognitive patterns. 6600 adults and 4400 children/adolescents (8–18 years) were tested with the Obesity Diagnostics and Evaluation System (AD-EVA). Potentially significant gender differences will be detailed for the entire juvenile cohort, the subgroup of obese children/adolescents as compared to the adult cohort in this article. Among all the subscales tested, obese girls primarily showed significantly higher values of (preclinical) eating disorders than boys. These data are relevant for both prevention and health promotion. No significant differences were found in regard to sports motivation. This warrants facilitation of physical activity for both genders. Further, a male predilection for “Snacks” and “High-fat food” that could be found in the total representative study group, could not be verified in the subgroup of obese girls and boys, thus suggesting a similarily unhealthy eating behavior in both genders of juvenility. © 2016, The Author(s).

Background: Interdisciplinary state-of-the-art interventions to treat obesity demand equally interdisciplinary outcome assessments. The Bariatric Evaluation Score for Children (BAREV-C) was developed to reliably and comprehensively assess the outcomes of non-surgical and surgical obesity treatment in children and adolescents. Methods: BAREV-C assesses medical, psychological, nutritional, and data of physical fitness data. The body mass index standard deviation score and waist measurement were selected to describe anthropometry. Serum triglycerides, high-density lipoprotein (HDL) cholesterol, blood pressure, and plasma glucose tolerance were selected as parameters of the metabolic syndrome. Relevant interdisciplinary variables were tested using the interdisciplinary Adiposity Evaluation kit, which assesses cognitive steering variables of eating and exercise behaviour as well as psychological comorbidities, exercise motivation, nutritional preferences, and quality of life associated with obesity. Physical fitness was assessed by means of the Physical fitness test battery. The values for the BAREV-C were determined in several steps and in all relevant disciplines pre and post intervention. Results: The BAREV-C facilitated the identification and quantification of significant changes of interdisciplinary variables associated with obesity for groups and individuals (tables of critical differences) as well. The degree of success or failure of an intervention can be quantified for each of the disciplines. Conclusions: The BAREV-C is the first comprehensive outcome instrument for pre-post-intervention evaluation of obese individual children as well as groups. It can be applied for intervention studies and can provide the clinician with a differentiated overview in daily practice. © 2013, Walter de Gruyter, Berlin/Boston. Source

Objective Despite alarming prevalence rates, surprisingly little is known about neural mechanisms underlying eating behavior in juveniles with obesity. To simulate reactivity to modern food environments, event-related potentials (ERP) to appetizing food images (relative to control images) were recorded in adolescents with obesity and healthy adolescents. Methods Thirty-four adolescents with obesity (patients) and 24 matched healthy control adolescents watched and rated standardized food and object images during ERP recording. Personality (impulsivity) and eating styles (trait craving and dietary restraint) were assessed as potential moderators. Results Food relative to object images triggered larger early (P100) and late (P300) ERPs. More impulsive individuals had considerably larger food-specific P100 amplitudes in both groups. Controls with higher restraint scores showed reduced food-specific P300 amplitudes and subjective palatability ratings whereas patients with higher restraint scores showed increased P300 and palatability ratings. Conclusions This first ERP study in adolescents with obesity and controls revealed impulsivity as a general risk factor in the current obesogenic environment by increasing food-cue salience. Dietary restraint showed paradoxical effects in patients, making them more vulnerable to visual food-cues. Salutogenic therapeutic approaches that deemphasize strict dietary restraint and foster healthy food choice might reduce such paradoxical effects. © 2015 The Obesity Society. Source

Background: Bariatric surgery is the most effective treatment to reduce weight permanently which is essential to avoid, to improve or even to cure life-threatening comorbidities. Little is known about changes of the psychological etiology and risk factors. Methods: The present study concentrated on psychological variables which are considered to cause or promote obesity. The changes of symptoms were measured by the AD-EVA test inventory. A total of 60 patients (24 male/36 female, age 18-71 years) were tested prior to gastric bypass or gastric banding (body mass index BMI M=44.95, SD=6.91) and postoperatively (BMI M=33.92, SD=7.23). Results: Following surgery the variables addiction (t=11.15, p<0.01) and binge eating disorder (t=2.13, p<0.05) showed significant changes across all patients and therefore confirmed a positive effect but restrained eating and bulimia remained unmodified after surgery. There were significant differences between the two bariatric methods (p<0.01). Discussion: A precise interdisciplinary evaluation is a prerequisite for deciding between gastric banding and the bypass technique as well as to define the need for preoperative and postoperative psychotherapy. © 2011 Springer-Verlag.

There is controversy about role of craving and addiction in obesity. We have shown that obese adults fulfill the minimum three criteria of ICD 10 for the diagnosis »addiction«, that they do not differ significantly from either other substance addicts, that BMI groups differ significantly in »addiction to abnormal food intake« and that addiction is a strong predictor of weight loss after surgical and behavioral interventions. Here we attempt to replicate this in children with the help of seven studies. In four cross sectional studies (n = 4428, 2480 resp. 1886, studies 1, 5 and 6), we surveyed 10-16-year old pupils from a representative selection of Austrian schools. We interviewed 160 morbidly obese young patients and their parents (age 10-16), who wanted to participate in therapy trainings sessions (study 7). In two longitudinal studies we evaluated 10-14 year old participants (n = 50, study 2 and n = 67, studies 3 and 4) of interdisciplinary obesity group training. We used the child version of the »Questionnaire on addiction to overeating« (3). Children too fulfill the minimum three criteria of ICD 10 for the diagnosis »addiction«, percentiles differ significantly in »addiction to abnormal food intake«, addiction is a strong predictor of weight regain and weight loss, distinction can be made between addiction to overeating and eating disorders and the subjective burden of feeling addicted is stronger than the burden of being obese. These results prove the relevance of food craving/addiction in childhood. Contemporary studies in neuroscience support these results. Source
