Study on the Mechanism of Eating Disorder
Anorexia NervosaBulimia NervosaEating disorders (EDs) are severe chronic psychiatric disorders with a not fully understood etiopathogenesis. Previous studies have revealed some biological mechanisms of EDs. However, the etiology and maintenance mechanism of EDs, especially the neuro-mechanisms is still unknown. To explore the pathogenic mechanism and treatment biomarkers of EDs, we design this study. the multidimensional data including the clinicopathological features, neuroimaging data (functional and structural magnetic resonance imaging), electroencephalogram and inflammatory cytokines will be used to investigate the biomarkers for diagnosis and treatment effectiveness.
A Multi-Site Study of MDMA-Assisted Psychotherapy for Eating Disorders
Anorexia Nervosa Restricting TypeBinge-Eating DisorderThis Phase 2, open-label, multi-site study will explore the safety and feasibility of 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy and adjunctive caregiver involvement in the treatment of 18 participants with eating disorders. The study will enroll 12 participants with anorexia nervosa restricting-type (AN-R) and six participants with binge eating disorder (BED). A supportive caregiver, such as a parent or partner, for each participant will also be recruited to participate in the study and receive non-drug psychotherapy support. The study will consist of Preparatory Sessions, Experimental Sessions of MDMA-assisted psychotherapy, as well as Individual and Dyadic Integrative Sessions. A flexible dose of MDMA will be given during Experimental Sessions, ranging from 80 to 120 mg with a supplemental half-dose of 40 or 60 mg 1.5 to 2 hours later, respectively, unless contraindicated. The primary outcome measure is the change in Eating Disorder Examination (EDE) results from Baseline to Visit 16 (Study Termination).
Decision Making, Daily Experiences, and Brain Activity in Young Adult Women
Binge-Eating DisorderThe investigators are doing a study of women with and without binge-eating disorder to learn more about what happens when people engage in everyday decision-making activities. The investigators are interested in learning more about brain activity during everyday decision-making and how everyday decision-making relates to a variety of daily experiences. Examples of everyday decisions include deciding which product to buy, deciding what to eat for a snack, and deciding how to spend free time.
Web-based Guided Self-help CBT-E vs Online G-CBT-E for Binge Eating Behavior
Feeding and Eating DisordersEating disorders with binge eating as the core feature include bulimia nervosa (BN) and binge eating disorder (BED). In recent years, the prevalence rate has increased rapidly, mostly among women, accompanied by emotional problems, physiological complications and increased risks of obesity and depression, which bring great pain to patients. Enhanced Cognitive Behavioral therapy (CBT-E) for eating disorders is an evidence-based and effective first-line psychotherapy for BN and BED. CBT-E is implemented in various forms. In addition to face-to-face therapy, online group CBT-E and guided self-help CBT-E can significantly reduce binge eating in BN and BED patients. However, there are no relevant clinical studies in China. Since 2008, the applicant has carried out CBT treatment and research on eating disorders, translated and published the self-help book "Overcoming Overeating", and accumulated rich clinical research experience. This study intends to establish a set of CBT-E self-help therapy courses suitable for Chinese binge eating patients, and conduct a randomized controlled study of web-based guided self-help CBT-E and online group CBT-E to compare the effectiveness of the treatment modalities in the treatment of binge eating and the feasibility of online guided self-help CBT-E and online group CBT-E in the treatment of binge eating.
Project THINK: Trajectories of Health, Ingestive Behaviors, and Neurocognition in Kids
Pediatric ObesityBinge-Eating DisorderOverweight/obesity and loss of control eating (characterized by the sense that one cannot control what or how much one is eating) are prevalent among children and adolescents, and both are associated with serious medical and psychosocial health complications. Although our recently published data suggest that youth with these conditions may have relative deficits in neurocognitive functioning, particularly working memory, understanding of how these processes and their neural correlates are related to change and stability in eating and weight-related outcomes over time is limited, thereby impeding development of targeted, optimally timed interventions. The present study aims to assess prospective associations between general and food-specific executive functioning and underlying neural substrates, and eating and weight outcomes among children at varying levels of risk overweight/obesity and eating disorders, which will help guide research efforts towards the development of effective prevention and intervention strategies.
Identifying Risk Factors That Predict Onset of Anorexia Nervosa and Bulimia Nervosa
Eating DisordersAcross the United States, thousands of children and adolescents suffer from eating disorders. Among young women alone, an estimated 2 to 4 percent are dealing with anorexia nervosa. Anorexia nervosa also has the highest mortality rate of any psychiatric disorder and produces a six-fold increased risk for death. Unfortunately, study shows that current treatments are only successful with 25 percent of patients and no eating disorder prevention program has been found to reduce future onset of anorexia nervosa. The goal of this study is to conduct a highly innovative pilot study that will identify risk factors that predict future onset of anorexia nervosa and investigate how the risk processes for anorexia nervosa are different from the risk processes for bulimia nervosa. The proposed pilot study will: Compare 30 healthy adolescent girls at high risk for anorexia nervosa to 30 healthy adolescent girls at high risk for bulimia nervosa, and 30 healthy adolescent girls at low risk for eating disorder in an effort to document risk processes that are present in early adolescence before anorexia nervosa typically emerges. Test whether elevations in the hypothesized risk factors predict future onset of anorexia nervosa over a four-year follow-up.
Improving Appetite Self-Regulation in African American Adults With Type 2 Diabetes
Type 2 DiabetesBinge EatingThe purpose of this 6-month randomized clinical trial is to examine the feasibility of recruitment, attendance, retention, program adherence, and satisfaction of a digital application designed, Centering Appetite to improve glucose scores (HbA1c) and binge eating in African American adults with type 2 diabetes. Intervention participants will receive type 2 diabetes education and web-based lessons on appetite self-regulation. Participants will also receive a Fitbit to monitor daily physical activity. The investigators will follow up with participants at six months.
Treating Binge Eating and Obesity Digitally in Black Women
Binge EatingBinge-Eating Disorder2 moreMore than 30% of Black women with obesity binge eat. Binge eating may increase the risk for the development of metabolic syndrome and binge-eating-disorder (BED), which is associated with severe obesity. Though several effective treatments for binge eating exist, Black women have not fared well. Not only has their inclusion in treatment trials been limited, but when participating, they are more likely to drop out, and/or lose less weight, compared to their White counterparts. Furthermore, treatment for binge eating is often not available in primary care and community-based settings places where Black women are more likely to receive treatment for their eating and weight-related concerns. Currently, there is scant intervention research to treat binge eating in Black women. With the highest rates of obesity (57%) nationally, Black women are in need of culturally-relevant treatments for binge eating and weight gain prevention. Given the established relationship between frequent binge eating and subsequent weight gain, addressing binge eating among Black women with obesity is imperative.
