Iron deficiency anemia: Causes and incidence
(Professional Guide to Diseases (Eighth Edition))

Iron deficiency anemia may result from:

❑ inadequate dietary intake of iron (less than 1 to 2 mg/day), such as in prolonged unsupplemented breast-feeding or bottle-feeding of infants or during periods of stress such as rapid growth in children and adolescents

❑ iron malabsorption, such as in chronic diarrhea, partial or total gastrectomy, chronic diverticulosis, and malabsorption syndromes, such as celiac disease and pernicious anemia

❑ blood loss secondary to drug-induced GI bleeding (from anticoagulants, aspirin, and steroids) or due to heavy menses, hemorrhage from trauma, GI ulcers, esophageal varices, or cancer

❑ pregnancy, which diverts maternal iron to the fetus for erythropoiesis

❑ intravascular hemolysis-induced hemoglobinuria or paroxysmal nocturnal hemoglobinuria

❑ mechanical erythrocyte trauma caused by a prosthetic heart valve or vena cava filters.

A common disease worldwide, iron deficiency anemia affects 10% to 30% of the adult population of the United States. It occurs most commonly in premenopausal women, infants (particularly premature or low-birth-weight neonates), children, and adolescents (especially girls). Persons who are at increased risk for iron deficiency include those of low socioeconomic status who don’t get a well-balanced diet that includes iron-rich foods.

About prevalence and incidence statistics:

The term 'prevalence' of Anemia, Iron-Deficiency usually refers to the estimated population of people who are managing Anemia, Iron-Deficiency at any given time. The term 'incidence' of Anemia, Iron-Deficiency refers to the annual diagnosis rate, or the number of new cases of Anemia, Iron-Deficiency diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
