Anorexia Concerns in Pre-Teens

There are many reasons that children on the cusp of adolescence may begin to present with disordered beliefs and behaviors related to their bodies and food. In the current political, sociological, and technological climate, children and teens are more aware of world events and diet and beauty trends than ever before. Not only that, this awareness has become a key aspect of identity-building both in-person as well as over social media.

A child may begin to shift toward vegetarianism or veganism after watching a Netflix documentary. An Instagram account may lead them to question why they don’t look like an influencer. The feelings of having no control over a global pandemic may lead a child to attempt to find that control in food. These are only a few very real scenarios that make pre-teens susceptible to the development of restrictive eating behaviors and anorexia nervosa (AN).

Risk Factors

While pre-teens view themselves as being on the “cusp of adulthood” due to the physical maturation changes they are experiencing, they are very much still children mentally and psychologically. This is a huge vulnerability factor, as it makes them susceptible to sociocultural influences, advertisements, and external pressures regarding body weight, shape, size, and appearance.

As pre-teens experience the overwhelming and confusing changes that come with puberty, their insecurity increases, particularly if they view themselves as developing differently than their peers. In a phase of life where fitting in can feel so important, these changes can make pre-teens feel different and uncomfortable and sometimes leading to an eating disorder such as anorexia or bulimia.

Advertisers in the diet and beauty industry are aware of this and, in fact, often purposely target this age-group for that reason. Family beliefs regarding one’s body, appearance, food, exercise, and self-worth are also hugely impactful on pre-teens’ developing minds.


The average age of onset for anorexia used to be between 13 to 17. It is now frighteningly between the ages of 9 to 12, with children as young as seven being diagnosed [1]. Pre-teen’s bodies are in a precarious state as they experience the “grey area” of no longer being a child but not yet having transitioned physically to adolescence. This places them at particular risk for the physical and psychological ramifications of anorexic behaviors.

“Children have a lower percentage of body fat, which means they get much sicker much faster than adolescents and adults…and because their bodies and brains are still developing, the most severe cases can permanently affect their development — limiting growth potential (and) damaging vital organs (particularly the heart, kidneys, and brain) — even when the eating disorder is eventually successfully treated [1].” The necessity of preventative efforts and education for pre-teens cannot be over-emphasized, as the consequences of anorexia development in this population are severe.

Despite a child’s reason for altering their eating or exercise behaviors, it is important to keep an open and authentic dialogue with them to learn their reasoning as well as the beliefs they are developing about themselves, their bodies, and their worth. Not engaging in these discussions results in children taking cues from the world they interact with in-person and via social media, and these cues may not be appropriate, empowering, or healthy.
