About 3 percent of U.S. adolescents are affected by an eating disorder, but most do not receive treatment for their specific eating condition, according to an  National Institute of Mental Health (NIMH)-funded study published online ahead of print March 7, 2011, in the Archives of General Psychiatry.

Researchers analyzed data from the National Comorbidity Study-Adolescent Supplement , a nationally representative, face-to-face survey of more than 10,000 teens ages 13 to 18. Previously published results found that about 20 percent of youth are affected by a severe mental disorder, and a substantial proportion of these youth do not receive mental health care. In this new study, the authors tracked the prevalence of eating disorders and the proportion of those youth who received treatment for these disorders.

According to the data, 0.3 percent of youth have been affected by anorexia (fear of getting fat that causes you not to eat), 0.9 percent by bulimia (bouts of overeating followed by purging), and 1.6 percent by binge-eating disorder(out of control eating). The researchers also tracked the rate of some forms of eating disorders not otherwise specified (ED-NOS), a catch-all category of symptoms that do not meet full criteria for specific disorders but still impact a person’s life. ED-NOS is the most common eating disorder diagnosis. Overall, another 0.8 percent had subthreshold anorexia, and another 2.5 percent had symptoms of subthreshold binge-eating disorder.

In addition, Hispanics reported the highest rates of bulimia, while Whites reported the highest rates of anorexia.   The majority who had an eating disorder also met criteria for at least one other psychiatric disorder such as depression. Each eating disorder was associated with higher levels of suicidal thinking compared to those without an eating disorder.

The prevalence of these disorders and their association with coexisting disorders, role impairment, and suicidal thinking suggest that eating disorders represent a major public health concern. In addition, the significant rates of subthreshold eating conditions support the notion that eating disorders tend to exist along a spectrum and may be better recognized by doctors if they included a broader range of symptoms. In addition, the findings clearly underscore the need for better access to treatment specifically for eating disorders.

You may have seen the cover article on our Spring Newsletter titled “Spotlight on Obesity: Is it just your weight?”  This article focuses not only on the epidemic of obesity in the U.S. but also on the serious health conditions that may result from obesity.  Although obesity is on the rise, however, eating disorders such as anorexia and bulimia still continue to be a problem, especially in women.  According to the National Alliance for the Mentally Ill (2003) 90 percent of individuals with eating disorders are women between the ages of 12 and 25.  Eating disorders are closely correlated with depression, substance abuse, and anxiety disorders, so it is important to diagnose and treat early.

The most common disorders are anorexia nervosa, bulimia nervosa, and binge-eating.  You may already be familiar with these disorders, but they are listed below along with some the complications that may arise.

Anorexia nervosa is a disorder categorized by obsession with weight and food causing individuals to starve themselves or to exercise excessively in order to maintain a weight typically far below the normal weight range for their height and age.  Complications of anorexia include, heart problems, anemia, permanent bone loss, malnourishment, absent menstruation and death.

Bulimia nervosa is categorized by periods of binge eating followed by vomiting or excessive exercise to get rid of extra calories or weight.  Individuals with bulimia are similarly obsessed with weight and food.  Both disorders are closely tied to self-image and thus may be difficult to treat.  Complications of bulimia include heart problems, digestive problems, tooth decay, absent menstruation and death.

Binge-eating disorder is still not considered a psychiatric condition, but may be treated similarly to bulimia and anorexia.  Binge-eaters tend to consume unusually large amounts of food on a consistent basis.  This disorder may lead to obesity and complications associate with obesity such as high blood pressure, diabetes, and heart disease.  In addition binge-eating disorder can cause psychological problems such as depression and suicidal thoughts.

Although the term eating disorder usually means one of the three disorders listed above, the term disordered eating is used to describe a variety of eating abnormalities that do not necessarily fall into, or are not severe enough to be categorized as one of the typical eating disorders.  Disordered eating may not be as serious in terms of complications, but it may lead to more serious eating disorders if left untreated or unaddressed.  According to a survey conducted by Self Magazine and the University of North Carolina, as many as 65% of American women between 25 and 45 exhibit disordered eating behaviors.  Women should not be afraid to seek help for issues they may have with eating, even if they do not think it is a severe eating disorder.  As peers, we should be supportive of women who are suffering from these diseases, and help them to overcome their issues.
