Preventing Obesity in Military Communities-Adolescents
ObesityOverweight1 moreTo determine whether reducing loss of control eating (LOC) with Interpersonal Psychotherapy-Weight Gain (IPT-WG) will be effective for adolescent military-dependents who report such behavior. The investigators will examine whether IPT-WG influences body weight gain trajectories and prevents worsening disordered eating, psychosocial problems, and metabolic functioning among military dependents at heightened risk for adult obesity and disordered eating. This study will provide key efficacy data for a new promising obesity prevention program for youth from military families.
Binge Eating Self-help Treatment for University Students
ObesityBinge Eating DisorderBEST4US compares the effectiveness of two forms of self-help interventions that target college students, ages 18 years to 22 years, who report binge eating. The overall question is whether one or the other format will prevent excess weight gain and lead to differences in eating behaviors. The two formats are (1) "pure self-help" (receipt of a self-help program via book form or online texts) and (2) a combination of the self-help program and guidance provided by a trained peer coach over the course of 8 weekly sessions.
Food and the Brain
Binge EatingThe proposed study will examine the role of reward and emotion in women with and without a history of binge eating. It is important to understand how the brain responds to reward and emotion in binge eating in order to identify different pathways toward binge eating and provide individualized targets for treatment. This is particularly important in light of the fact that for many patients, the current treatments for binge eating are not effective.
fMRI and Ghlrein in Obesity and Binge Eating Disorder
ObesityBinge Eating DisorderBinge Eating Disorder (BED) may be associated with he development of obesity. However, the pathogenesis of BED is currently unclear, thus making the development of treatment and prevention strategies for BED difficult. Differences in the mechanisms regulating food intake may go some way to reveal potential mechanisms for BED.The purpose of this study is to investigate the responses of key gut-derived hormones that are associated with the regulation of food intake and functional brain activity to food cues using fMRI in BED patients and weight matched controls.
Inhibitory Control and Eating Disorders
Anorexia NervosaBulimia Nervosa1 moreExecutive functions are part of the high-level cognitive processes essential to the proper functioning of human cognition. They consist mainly of flexibility, updating and inhibition. Some studies have shown a correlation between executive disorders (impaired executive function) and psychiatric disorders such as obsessive-compulsive disorder or phobias. These executive disorders are related to dysfunctions of the fronto-striatal loops. In addition, other studies have investigated the link that may exist between eating disorders such as anorexia or bulimia nervosa and executive functioning. Anorexia nervosa, bulimia nervosa and binge eating disorders are eating disorders characterized by a dysfunction in food intake with restriction of food or compulsions as well as strong concerns about the body schema. Concerning the executive functioning, these studies highlight a lack of cognitive flexibility for patients with anorexia nervosa and bulimia nervosa but also dysfunctions depending on the type of pathology (anorexia nervosa or bulimia nervosa). These studies also highlight the beneficial effects of cognitive remediation on people with eating disorders. However, the investigation of the inhibitory control has not yet been specifically studied. Moreover, since eating disorders are structurally different, a comparison between several pathologies would be interesting to consider. The aim of this study is to determine if a dysfunction of inhibitory control can be highlighted in people with eating disorders. This study would also allow further researches about cognitive remediation suitable for the specific difficulties encountered in these diseases.
Interoceptive Nutritional Processing in Healthy Participants and Patients With Binge-Eating-Disorder...
Food HabitsBinge-Eating DisorderBinge-Eating-Disorder (BED) is a common eating disorder characterized by recurring episodes of uncontrollable eating. The underlying neural mechanisms are largely unknown. However, dysfunctional hormonal satiety signaling as well as dysfunctional neural processing of food cues are discussed as possible casual factors in the development and maintenance of this disorder. Additional research is needed to specify the exact contribution of these observations and how they interact with each other. Accordingly, the current study plans to investigate metabolic gut-brain signaling to better understand the underlying causes of abnormal eating behavior. To this end, 25 healthy normal weight control participants as well as 25 patients with BED will be recruited. The responsivity of the hypothalamus (i.e., the core region of homeostatic control) and its interaction with the mesocorticolimbic reward system will be assessed by applying a single-blind, randomized, crossover design of intravenous infusion of glucose or NaCl. This approach allows the study of gut-brain signaling to the hypothalamus and the reward system by controlling for sensory aspects of food intake (sight, smell, and taste). The interaction between the hypothalamus and the mesocorticolimbic reward system will be investigated using an effective connectivity analysis. FMRI with high spatial resolution and with an optimized protocol for the investigation of the hypothalamus and the mesocorticolimbic reward system will be employed. A better understanding of the underlying psychobiological mechanisms of BED is a fundamental requirement for the development of improved prevention and treatment strategies
Description and Evaluation of Eating Disorders in Elite Athletes (TCA SHN)
Eating DisordersAnorexia Nervosa2 moreAthletes in particular elite athletes have obsessional food and body concerns, in bond with a worship of the performance more and more invading, which lead to clinical and subclinical eating disorders. These eating disorders differ according to the disciplines and are difficult to diagnose in athletes because there are insufficiently described. Our aim at estimating the frequency of eating disorders in athletes and describing eating disorders by means of somatic, dietetic and psychological evaluations.
