Eating Disorders

Everyone knows that disordered eating has a negative effect on physical health, but it can also cause other mental health problems. A prospective longitudinal study showed that disordered eating is a significant risk factor for future depression and bullying by peers.
Anorexia nervosa, bulimia nervosa, and binge-eating disorders are more common among females, but the correlation between eating disorders and bullying and depression were the same for both sexes.

Previous studies have examined bullying causing disordered eating and depressive thinking, but this study showed that they can feed each other. Both depression and disordered eating are associated with low production of serotonin. Interventions to create positive eating habits during adolescents could lower bullying prevalence by 30%. These interventions could also prevent depression.
