Iron deficiency is the most common nutritional disorder in the world and is a major cause of anemia associated with situations involving chronic blood loss or rapid growth such as during infancy, pregnancy and adolescence. This deficiency leads to impairment in psychomotor development, learning ability, appetite, growth and immune response. In adolescence, inadequate dietary habits are often observed and intensive physiological and psychological changes are seen that when combined can impair growth and increase the risk of developing iron deficiency or other nutritional disorders, especially during puberty. Thus, the diagnosis of iron deficiency among adolescents should always be considered so that measures can be taken to reduce the incidence of anemia, impairment of the immune system and improve school performance.
