The adolescent and teenage years are a time of growth and transformation, physically, mentally and biologically. In moving towards adulthood, young people begin to discover who they are. Independent of parents, they begin to establish friendships and go through puberty. There are obvious physical changes associated with adolescence and puberty. But a large amount of internal change also occurs. Adolescent eating disorder statistics show 2.7% of teens in the U.S. between 13 and 18 years old have an eating disorder. For many teenagers, entering into puberty can be a time wrought with intense emotions, confusion, and stress. This period of change is what makes teens susceptible to developing eating disorders.

Adolescent eating disorders (such as anorexia, bulimia, binge eating disorder, and compulsive overeating) are concerns every parent hopes to avoid. Yet, because so many young people struggle with eating disorders, it is important to know the facts.

  1. 4% of adolescents and teens, ages 13 to 18, suffer from an anorexia, bulimia, or binge eating disorder.

Anorexia is a serious, life-threatening eating disorder affecting many teenagers. Those who suffer from anorexia go to extreme lengths to control their food intake. Or, worse, they avoid eating altogether. Additionally, those with anorexia also have a distorted body image. They still feel “fat,” regardless of how thin they become.

Teenagers with bulimia typically binge (periods of uncontrollable overeating) and purge (self-induce vomiting). Inducing vomiting is the most common compensatory behavior. But there are others, such as laxatives or excessive exercise.

Binge-eating disorder is characterized by excessive eating. Many teens who suffer from binge-eating disorder describe feeling like they have no control over their behavior. They also experience intense guilt and shame following a binge.

  1. 50% of teens with anorexia will develop bulimia or binge-eating disorder

Anorexia is an eating disorder marked by significantly restricting caloric intake due to intense fear of weight gain. Teens with anorexia engage in some level of self-starvation. This extreme dietary restriction often leads to another eating disorder, such as bulimia or binge-eating disorder. Long periods of malnutrition take a toll on the body’s systems and organs. This, along with experiencing hunger cues and pains, can eventually lead a teen to “giving in” to the desire for food. And like the extreme nature of the restricting, once a teenager begins to eat again, it can be extreme as well (such as binging).

  1. 90% of teens with anorexia are female

Anorexia most commonly emerges in the adolescent and teenage years. This eating disorder develops from a number of factors including, for some, the onset of dieting, converge. While dieting does not cause anorexia, the reduction in calories dieting entails often triggers the disorder. Especially in those who are genetically predisposed to it.

  1. The average amount spent on eating disorder research per affected individual is .93¢

In comparison, $44 per affected individual is spent on autism research. Schizophrenia research spends $81 per affected individual. Lastly, $88 is spent on Alzheimer’s disease research per affected individual.

  1. Young women with anorexia are 12 times more likely to die than women the same age who do not have anorexia.

Anorexia nervosa is the third most common chronic illness among adolescent and teenage girls. Anorexia also has the highest mortality rate of any psychiatric disorder.

  1. 50% of teenage girls and 30% of teenage boys use unhealthy weight control behaviors.

Some of these behaviors include skipping meals, fasting, smoking cigarettes, purging (throwing up), taking laxatives, over-exercising, taking diet pills, hiding food, and drinking highly caffeinated energy drinks.

  1. 50% of teens with an eating disorder also suffer from depression

Depression may lead to eating disorders in teenagers, but in many cases, the eating disorder itself is what triggers depression.  Malnourishment causes physiological changes in the brain that can affect emotion regulation and mood.

  1. 69% of females (ages 10 to 18) state that photographs of models and celebrities in the media motivated their “ideal” body shape.

The rate at which teens are becoming aware of their body shape and size is getting younger and younger, and media plays a big part in this. Many teenagers site media as being on of the biggest influencers when it comes to body image (how one perceives his or her body when looking in the mirror).  In the United States, media and overall popular culture strongly idealize thinness, and adolescents and teens are amongst the population most strongly influenced, especially with the popularity of social media. Unfortunately, the substantial influence the media plays in teenagers lives leads many (even teens with a normal body weight), are still susceptible to viewing themselves as “overweight” or “fat”. The importance placed on thinness in the media can create a desire to achieve the impossible in terms of body shape and size, and can obviously become a trigger to dieting and weight loss.

  1. By age 17, 89% of girls have dieted

In this day and age, being concerned with weight and body size is incredibly common, especially amongst adolescent and teenaged girls.  Adolescence is when bodies begin to change, and there is an increased awareness of media and peer pressures.  Couple this with a lack of knowledge around nutrition, and many teenage girls are engaging in some very risky dietary behaviors as a way to cope with body dissatisfaction.  Although all teenage girls are susceptible, there are certain risk factors that make some more likely to use dangerous diets including:

  • Family factors – low family connectedness, absent or neglectful parents, or dieting amongst parents can all contribute to increasing a teenage girl’s risk of engaging in dieting behavior.
  • Environmental factors – poor school involvement, bullying/teasing by peers (especially around weight-related issues), or participation in a sport that is weight-focused will likely make a teen more prone to using diets.
  • Individual factors – being female alone increasing one’s inclination towards dieting. Other individual factors include low self-esteem, early puberty, being overweight or obese, or practicing vegetarianism.
  1. How many teen boys actually have eating disorders? Boys make up approximately 10 to 15% of the adolescent and teenage population with eating disorders, but are much less likely to seek treatment due to the gender stereotypes surrounding the disorders.

Many people believe that an eating disorder is a “female” problem.  And while more common in girls and women, eating disorders do affect males as well.  Because there is far more discussion about teenage girls and eating disorders, many teen boys are reluctant to discuss their symptoms or admit they have a problem.  For some, there may be fear of appearing less masculine, or being judged by friends and peers.  This unfortunately prevents many male teenagers from getting the help they need.

While it is possible for any boy to develop an eating disorder throughout his adolescent and teenage years, there are certain factors that increase one’s likelihood including:

  • Involvement in certain athletic activities – such as bodybuilding, wrestling, swimming, and gymnastics all increase a teenage boy’s chances of developing an eating disorder. This is because these are sports where weight control can influence performance, and coaches often encourage maintaining a certain weight range.
  • Sexual orientation – homosexual males or males questioning their sexual identity are at an increased risk of struggling with an eating disorder.
  • Being overweight – teenage boys who are currently overweight, or were overweight as children are more prone to eating disorders. This is especially true if a bullying and/or teasing is involved.
  • Parental dieting – parents model behaviors to their children, whether they intend to or not. Thus, teenage boys who see one or both parents using restrictive diets to lose weight may begin to practice similar behavior.
