What Can We Do To Stop The Rise In Anorexia
While theres no easy answer, most experts agree that banning pro-anorexia sites and moving away from a culture of airbrushing celebrities and models is a step forward. We also need to look at how to address low self-esteem and academic pressure, starting with better emotional support for young people at school.
Meanwhile, teachers, GPs, friends and family need to get better at spotting the warning signs, as the research suggests that early intervention is the key to successfully combating eating disorders.
Point Prevalence Of Accurate Eds
Seventy-three articles reported ED point prevalence . Among these studies, the weighted means of point ED prevalence were 5.7% for women and 2.2% for men . The weighted means of AN point prevalence were 2.8% for women and 0.3% for men. For BN, the weighted means of point prevalence were 1.5% for women and 0.1% for men. For BED, the weighted means of point prevalence were 2.3% for women and 0.3% for men. Finally, the weighted means of point EDNOS prevalence were 10.1% for women and 0.9% for men.

Evolution And Anorexia Nervosa
One of my teachers at Children’s Hospital characterized anorexia nervosa as “a desperate disease.” On the inpatient unit where the young women were hospitalized, it was difficult to find one who would stay still. They were forbidden to exercise, but during groups would move their legs and fidget constantly to burn calories. Quite a feat, as some of them still had dangerously low blood pressure and body temperature from the self-induced starvation. Often purging and starvation were combined , and they had to be watched in the bathroom to prevent purging or claiming constipation in order to get laxatives.
My evolutionary psychiatry interest has always been in how psychiatric disorders have changed over the past 100 years of rapidly changing lifestyle and diet. Anorexia nervosa is one of those illnesses that was exceedingly rare until 50 years ago, then escalated rapidly and finally leveled off for about the past 20 years, though those who are affected encompass more children and more men now than ever before. My educated guess is that only a small percentage of us are capable of starving ourselves outright without being under lock and key, and that vulnerable population shows symptoms earlier and earlier in life as societal pressures and the obesogenic environment increases.
The authors speculate that “AN may be caused by defects in the evolutionarily conserved response to food and nutrient shortage associated with reduced calorie intake.”

New Eating Disorders On The Horizon
In the past decade, more eating disorders have been widely recognized. For example, orthorexia is an eating disorder that is still not recognized in the current version of the DSM but eating disorder therapists currently recognize this as a serious disorder that has resulted in many disordered eating patterns. This term was first coined by Dr. Steven Bratman M.D. in 1996 and has gained a large audience of followers including many professionals in the psychiatry and eating disorder world. Healthy eating is not as healthy when it becomes an overwhelming obsessive behavior creating conflicts within the inner self. Unlike individuals with anorexia nervosa who are obsessed with losing weight or preventing weight gain, individuals with orthorexia may not be obsessed with their weight but they are obsessed with healthy eating, however, both of these populations have an underlying problem with self-control.
The Dsm Adds An Eating Disorders Section
Eating disorders became a diagnosable mental health condition in 1980 when it was added to the Diagnostic and Statistical Manual of Mental Disorders . The addition of eating disorders in the DSM was a major transition in the history of eating disorders. This recognition legitimized eating disorders as a serious mental health challenge that warranted treatment and care.
Eating Disorders And Athletes
- Disordered eating can occur in any athlete, in any sport, at any time, crossing boundaries of gender, age, body size, culture, socioeconomic background, athletic calibre and ability .
- Overall, there is a higher prevalence of disordered eating and eating disorders in athletes compared to non-athletes .
- It is estimated that up to 45% of females and up to 19% of male athletes experience disordered eating and/or an eating disorder .
- Research shows that people who engage in aesthetic, gravitational and weight-class sports such asweight-lifting, boxing, horse racing, rowing, gymnastics, swimming, figure skating and danceare at higher risk of disordered eating and/or an eating disorder .
Th And 13th Centuries: Self
A prime example of cultural shifts is found in the earliest recordings of disordered eating: religious starvation. During the 12th and 13th centuries, self-starvation was considered an act of piety and great faith. Disregarding ones basic need for sustenance was the ultimate statement of devout commitment to God.
The secondary consequence of this behavior was the glorification of the starvation process. This attracted people who searched for martyrdom or wanted to express their intense devotion to God.

Dr Pierre Janet Noted Bulimic Behaviors In Patients
When bulimia behaviors were observed in patients of Dr. Pierre Janet, the spectrum of eating disorders expanded. Eating disorders were starting to be observed in a new light. Rather than being strictly tied to a medical model, these newly observed behaviors shed light on other possible explanations.
What Is An Eating Disorder
Eating disorders include anorexia nervosa, a form of self-starvation bulimia nervosa, in which individuals engage in repetitive cycles of binge-eating alternating with self-induced vomiting or starvation binge-eating disorder , which resembles bulimia but without compensatory behaviors to avoid weight gain avoidant restrictive food intake disorder in which people may have lack of interest in food, avoid certain textures or types of foods, or have fears and anxieties about consequences of eating unrelated to shape or weight concerns and other specified feeding and eating disorders . Eating disorders can occur in any age group, gender, ethnic or racial group.
Anorexia nervosa and bulimia are psychiatric illnesses that center on food and its consumption and are usually characterized by:
- Excessive preoccupation with food and dissatisfaction with ones body shape or weight
- A compulsion to engage in extreme eating habits and unhealthy methods of weight control such as: o Fasting or binge-eating o Chewing and spitting or regurgitating food o Excessive laxative, diuretic, or diet pill abuse.
These unhealthy behaviors and preoccupations can develop into a consuming passion and come to interfere with physical, psychological and social well-being.

In the DSM-III , Eating Disorders debuted as a diagnostic category under the rubric of disorders of infancy, childhood, or adolescence. Bulimianot yet called bulimia nervosamade its first appearance in this edition. The other eating disorders included in DSM-III were anorexia nervosa, pica, rumination disorder, and atypical eating disorder.
With the publication of the DSM-IV in 1994, bulimia nervosa appeared in its current form, with the required feature of shape and weight concerns. Binge eating disorder was also mentioned for the first time. At this point, BED was still not known as an independent disorder but included in an appendix as a proposed diagnosis for future study.
In this edition, Anorexia Nervosa and Bulimia Nervosa were moved out of the disorders of infancy, childhood, or adolescence and became their ownEating Disorderswhile the other disorders remained in the category Feeding and Eating Disorders of Infancy or Early Childhood.
Binge eating disorder finally made an appearance as an independent diagnosis in the DSM-5 in 2013. The categories of Eating Disorders and Feeding and Eating Disorders of Infancy or Early Childhood were reunited in the new umbrella category, Feeding and Eating Disorders. The DSM-5 also included avoidant restrictive food intake disorder , for the first time. It replaced Feeding Disorder of Infancy or Early Childhood.
Eating Disorders Development Timeline
As we look back at the history of eating disorders timeline, we can see how our understanding of the condition has evolved. Like any disorder, the root causes are examined based on the most recent knowledge available.
As a result, the understanding of eating disorders has shifted throughout history as our body of knowledge has grown. Even with our current level of knowledge, more information is being gathered about eating disorders, which helps inform future studies and treatment options.

How Eating Disorder Research And Treatment Have Evolved
In this century alone, the awareness of anorexia, bulimia and binge eating disorder has increased substantially. Eating disorder treatment now encompasses a holistic model that addresses multiple approaches: medical, psychological, nutritional, and more.Today, Eating Recovery Center converts their treatment model in Adult Programs to Acceptance and Commitment Therapy in addition to established principles of medical stabilization and nutritional rehabilitation. Using skills from Cognitive Behavioral Therapy and Dialectical Behavior Therapy therapeutically, ACT provides the theoretical framework to understand what processes help people get well.ERC also focuses on caregivers and support system as the agents of change and healing through their commitment to a variety of family treatment methods .Additionally, the stigma associated with body size, as well as mental health disorders, shows promise of decreasing, thanks in larger part to the tireless work of several campaigns, such as Love Your Tree, Say it Brave and Health At Every Size. These initiatives empower individuals and their families to seek help if they experience eating disorders. More people are learning that not only do these disorders have a name, but long-lasting recovery is also possible.
Existing Evolutionary Psychological Hypotheses For Eating Disorders
There are six existing evolutionary hypotheses for the ultimate causation of eating disorders. The leading evolutionary hypothesis for BN and BED is the thrifty genotype hypothesis. It suggests that binge eating is a psychological adaptation which arose because extra energy stores were protective in the evolutionary history of our species: they helped to avoid malnutrition, helped survival during famines and regulated reproduction . In an extension of this hypothesis, the dual intervention point model posits that the body has upper and lower set points for the level of body adiposity if these are exceeded, physiological feedback mechanisms are triggered . The minimum set point for adiposity is needed to avoid starvation, while the maximum set point is determined by risk of predation. As the risk of predation has declined, genes coding for higher maximum set point have become more common, and fewer people reduce caloric intake to prevent weight gain .
Eating disorders are often socially contagious in friendship groups and may spread in the school environment . For example, if ones friends have a low BMI due to eating disorder, one might perceive ones own body to be relatively large, leading to higher body dissatisfaction and a higher probability of developing eating disorders. This sociodevelopmental etiology of eating disorders is supported by findings that in schools with greater proportions of underweight girls, other girls are more likely to try to lose body weight .

What Are Eating Disorders
Eating disorders are behavioral conditions characterized by severe and persistent disturbance in eating behaviors and associated distressing thoughts and emotions. They can be very serious conditions affecting physical, psychological and social function. Types of eating disorders include anorexia nervosa, bulimia nervosa, binge eating disorder, avoidant restrictive food intake disorder, other specified feeding and eating disorder, pica and rumination disorder.
Taken together, eating disorders affect up to 5% of the population, most often develop in adolescence and young adulthood. Several, especially anorexia nervosa and bulimia nervosa are more common in women, but they can all occur at any age and affect any gender. Eating disorders are often associated with preoccupations with food, weight or shape or with anxiety about eating or the consequences of eating certain foods. Behaviors associated with eating disorders including restrictive eating or avoidance of certain foods, binge eating, purging by vomiting or laxative misuse or compulsive exercise. These behaviors can become driven in ways that appear similar to an addiction.

Eating Disorders On The Rise
A Capitol Hill briefing calls attention to eating disorders.

Mindi Rold, an anorexia survivor, began dieting when she was 8. “Losing weight was an obsession,” she said.
For years, her family searched for help. Their insurance company refused any treatment except hospitalization, and she spent more than 12 years in and out of hospitals. “I believed I deserved to be punished and didn’t deserve food. The hospitals never worked at these underlying problems.”
After years of failed treatment, an attempted suicide and a “lost childhood,” Rold began her road to recovery in 1993 in a 12-step, inpatient program, she said. Today, at 27, she suffers from osteoporosis, fibromyalgia, stunted growth and has only a 20 percent chance of conceiving children.
Rold told her story at a July Capitol Hill briefing on eating disorders co-sponsored by the Eating Disorders Coalition for Research, Policy and Action and the Congressional Children’s Caucus.
“This is a serious mental illness that has physiological consequences,” said psychologist and coalition executive director Jeanine Cogan, PhD. “The important message is people are dying–eating disorders kill. The other important message is that there is help. There are people who survive.”
“We shouldn’t have any more lives lost, no more suffering,” she said. “It’s time to wake up America about eating disorders.”
The Eating Disorders Coalition has identified several policy priorities, such as:

How Do You Know Its An Eating Disorder
Eating disorders are more common than you might guess. National surveys estimate that 20 million women and 10 million men in America will have an eating disorder at some point in their lives. The behaviors associated with eating disorders vary.
The three most common ones are:
- Anorexia: A condition characterized by weight loss and a distorted body image, in which the person has a fear of gaining weight. People with anorexia dramatically restrict the calories and types of foods they consume, may exercise compulsively and, in some cases, purge by vomiting or use laxatives.
- Bulimia: A cycle of binging on food and compensating with such behaviors as self-induced vomiting. When a person is having a bulimic episode, they feel unable to control the amount of food they are eating.
- Binge-eating disorder: This is similar to bulimia in that it involves episodes of uncontrolled eating, but it does not involve purging. Binge-eating disorder is the most common eating disorder and the one doctors know the least about at this point.
Some people dismiss the significance of their behaviors and may not even be fully aware that they have a problem that requires treatment, Lydecker says.
The study was based on the 2012-13 National Epidemiologic Survey on Alcohol and Related Conditions, which included responses from people who met standard criteria for lifetime eating disorders and who answered questions regarding whether theyd sought help.
Key Processes That Maintain Eating Disorders
According to cognitive behavior theory, a distinctive self-evaluation scheme , i.e., the overvaluation of shape, weight, eating and their control is of central importance in maintaining eating disorders.
Indeed, the other clinical features seen in these disorders seem to derive directly from this core psychopathology. These include extreme weight-control behaviors , various forms of body checking and avoidance, feeling fat, and preoccupation with eating, weight, and shape. These features of eating disorders are in fact expressions of the individuals belief that controlling their weight, shape and eating is of extreme importance in their self-evaluation.
The one behavior that is not a direct expression of the overvaluation of shape, weight, eating and their control is the binge-eating episode. This behavior is present in a large subgroup of people with eating disorders, and it derives indirectly from this overvaluation through the following mechanisms:
1. Severe undereating. The overvaluation of shape, weight, eating and their control can lead an individual to undereat. Doing so produces several changes of the neuroendocrine signals which control food intake, messaging hunger over satiety/satiation.
3. Events and associated mood changes. People tend to maintain binge-eating episodes through three main mechanisms:

Avoiding Treatment For Eating Disorders Can Lead To Other Problems
Treatment can be critical for a multitude of reasons, one being that eating disorders have one of the highest mortality rates of any mental health illness. They can eventually lead to such serious physical complications as cancer, diabetes, and organ failure, if not treated. They are associated significantly with suicide attempts, adds Ivezaj.
Michael Lerner, MD, a Yale Medicine otolaryngologist, says cases that go untreated can lead to symptoms usually associated with such conditions as acid reflux. When the larynx or throat is continually exposed to acid and pepsin from the stomach, the result can be chronic inflammationand in the worst cases, eventual precancerous changes, he says.
In severe cases, frequent and vigorous retching or vomiting can lead to stricture of the esophagus, which can result in dysphagia , Dr. Lerner says. People with these conditions might find that they feel the urge to clear their throats frequently or notice a foreign body sensation in their throat. So, otherwise common symptoms such as voice change and throat sensitivity, which are typically attributed to allergies or acid reflux, could, in fact, also be due to an eating disorder, he says.
