Diagnosis of Binge Eating Disorder
Binge Eating Disorder is characterized by recurrent episodes of binge eating, occurring at least once a week for three months. Such an episode involves excessive consumption of food, significantly larger than what other people would eat in a similar time frame. These episodes involve a lack of control over one’s eating, manifesting as either the inability to stop eating or a feeling of dissociation during the episode. The loss of control may not be complete, as more significant distractions may stop the individual from eating. However, the type of food that is consumed is not important, as binge eating implies consuming large quantities of food rather than a specific nutrient.
The Binge Eating Disorder is diagnosed when binge eating causes significant distress and is associated with at least three of the following behaviors:
- Eating much faster than normal
- Eating until feeling uncomfortably full
- Eating large amounts of food without feeling physically hungry
- Eating alone due to embarrassment
- Feeling disgusted, depressed, or guilty afterward
However, a study necessitated the need for additional diagnostic criteria for Binge Eating Disorder. The study suggests cognitive features, such as dysfunctional attitudes regarding eating, weight, and shape, dietary restraints, and behavioral and cognitive components as additional diagnostic criteria. This is founded on the basis of current diagnostic criteria focusing too much on behavioral aspects, rather than considering cognitive aspects as well.
Associated Features that Support the Diagnosis
Although Binge Eating is linked to overweight and obese individuals since they are most likely to seek treatment, it can also be diagnosed in individuals of normal weight. However, Binge Eating Disorder is different from obesity, as most obese individuals do not frequently binge eat. In comparison to obese individuals without Binge Eating Disorder who have similar body weights, those with the disorder consume more calories in controlled eating behavior studies. They also experience greater functional impairment, reduced quality of life, increased subjective distress, and higher rates of psychiatric comorbidities.
Prevalence od Binge Eating Disorder
In the United States, the twelve-month prevalence of Binge Eating Disorder among adults aged 18 and older is 1.6% for females and 0.8% for males. The gender disparity in Binge Eating Disorder is less pronounced than in bulimia nervosa.
A study from 2021 exploring the epidemiology of binge eating states that 1.5% of women and 0.3% of men worldwide are affected by the disorder, while lifetime prevalence rates range from 0.6% to 1.8% for women and 0.3% to 0.7% for men. The study also states that many adults suffering from Binge Eating Disorder have long-term symptoms, yet less than half are diagnosed in healthcare settings. Binge Eating Disorder frequently co-occurs with obesity, type 2 diabetes, and hypertension. Up to 23% of individuals with binge-eating disorder have attempted suicide, and 94% report lifetime mental health issues.
Furthermore, an article from 2013 compares the prevalence of Binge Eating Disorder and bulimia nervosa in the World Mental Health Surveys. The study involved 24,124 respondents from 14 countries, revealing that the lifetime prevalence of binge-eating disorder is consistently higher than that of bulimia nervosa. The median lifetime prevalence of Binge Eating Disorder is 1.4%, compared to 0.8% for bulimia nervosa. Crucially, the analysis also points out that fewer than half of those with Binge Eating Disorder receive treatment.
Development and Course
The development of Binge Eating Disorder remains poorly understood. Children can exhibit both binge eating and loss-of-control eating without consuming excessive amounts of food, which are linked to increased body fat, weight gain, and psychological issues.
Binge eating is particularly common among adolescents and college students, and loss-of-control eating, or episodic binge eating might, serve as early indicators of potential eating disorders for some individuals. However, some studies, such as one published in 1998, indicate that various adverse childhood experiences, including sexual and physical abuse, parental depression, and repeated negative comments about weight and shape, are associated with Binge Eating Disorder. When compared to general psychiatric controls, the study observed that individuals with Binge Eating Disorder reported higher exposure to childhood obesity and critical comments about their appearance.
Furthermore, a study published in 2006 analyzed how stress responses contributed toBinge Eating Disorder. It suggests that stress-induced cortisol may drive overeating and abdominal obesity, a phenomenon observed in both animal models and humans. The study also suggests that future research should integrate behavioral and physiological models to better understand stress-induced eating since previous studies have not considered cortisol levels as a vital factor in Binge Eating Disorder.
Studies indicate that remission rates for Binge Eating Disorder are higher than for bulimia nervosa or anorexia nervosa. Despite this, Binge Eating Disordertends to be persistent, with a severity and duration similar to that of bulimia nervosa. It is uncommon for individuals with Binge Eating Disorder to transition to other eating disorders.
Culture and Gender-Related Diagnostic Issues
Culture
It is generally accepted that Binge Eating Disorder is prevalent at similar rates across various industrialized nations, such as the United States, Canada, numerous European countries, Australia, and New Zealand. Within the United States, the prevalence of binge-eating disorder appears to be similar among non-Latino whites, Latinos, Asians, and African Americans. However, some studies, such as a study from 2001, observe that cultural beliefs and attitudes play a significant role in the development of eating disorders.
It highlights that these disorders are more prevalent in various cultural groups, including non-Western societies, than previously recognized. The study indicates that cultural changes, such as adopting Western values, increase vulnerability to eating disorders. This can occur over time within a society or when an individual immigrates to a new culture. The study also calls for culturally competent approaches to treatment and prevention, stressing the importance of understanding and integrating cultural influences in clinical care.
Gender
A study from 1997 compared gender differences in Binge Eating Disorder. According to the study, women reported higher tendencies to eat in response to negative emotions, particularly anxiety, anger, frustration, and depression. However, although women were more likely to develop Binge Eating Disorder, men and women who do suffer from the condition did not differ significantly in eating disturbances, shape and weight concerns, interpersonal problems, or self-esteem.
Interestingly, another study from 1999 explored Binge Eating Disorder specifically among the female population in Austria. The study found that women with Binge Eating Disorder were more likely to have dieted within the past year and exhibited restrained eating behavior compared to those without binge eating issues, hinting that these may pose potential triggers for Binge Eating Disorder as well.
Possible Causes
Bulimia Nervosa: Both Binge Eating Disorder and bulimia nervosa involve recurrent binge eating. However, binge-eating disorder lacks the compensatory behaviors (e.g., purging, excessive exercise) seen in bulimia nervosa. Unlike bulimia nervosa, individuals with Binge Eating Disorder do not engage in sustained dietary restriction but may frequently attempt dieting. Treatment response is generally better for binge-eating disorder.
Obesity: Binge Eating Disorder is linked to overweight and obesity but differs in key aspects. Individuals with the disorder show higher concerns about body weight and shape and have higher rates of psychiatric comorbidities compared to those with obesity alone. Effective long-term psychological treatments exist for binge-eating disorder, unlike obesity.
Bipolar and Depressive Disorders: Increased appetite and weight gain are symptoms of major depressive episodes and atypical features in depressive and bipolar disorders. Binge eating can occur in these contexts, and if the full criteria for both disorders are met, both diagnoses should be given.
Borderline Personality Disorder: Binge eating is included in the impulsive behavior criterion for borderline personality disorder. If criteria for both disorders are met, both diagnoses should be assigned.
The Efficacy of Cognitive-Behavioral Therapy (CBT) in Binge-Eating Disorder
CBT is a well-established and empirically supported treatment for Binge Eating Disorder, focusing on altering dysfunctional eating patterns and thinking errors related to food, body image, and self-worth.
A study from 2011 for example, compared the effectiveness of CBT and Behavioral Weight Loss (BWL) in the treatment of Binge Eating Disorder. The study found that CBT was superior in reducing binge-eating frequency up to 12 months post-treatment, with remission rates of 51% for CBT compared to 36% for BWL. However, BWL produced greater short-term weight loss during treatment. Combining these to therapies, however, did not enhance the outcome when compared to each treatment individually.
Furthermore, a study published in 2012 advocates for CBT as the first line of treatment for Binge Eating Disorder, as it provided significant improvements in eating behaviors and psychological functioning. CBT treatment consisted of educating patients about binge eating, identifying problematic eating patterns, cognitive restructuring, and relapse prevention and through this approach produced remission rates of 40% to 60% and maintained treatment effects for up to 2 years post-treatment.
Another study from 2012 examined the effectiveness of CBT and medication for Binge Eating Disorder. According to the study, CBT is shown to be a beneficial treatment, particularly for patients with lower self-esteem, higher negative affect, and significant overvaluation of shape and weight. These patients exhibited more significant reductions in eating disorder psychopathology and depression levels. Crucially, the study highlighted the importance of tailored treatments based on individual patient characteristics. Most research thus underscores the efficacy of CBT as a highly effective treatment for Binge Eating Disorder, offering significant and sustained improvements in eating behaviors and psychological well-being, particularly when tailored to individual patient needs.
