What is the most common nutritional deficiency in childhood?

• A. Iron deficiency anemia
• B. Anemia of chronic disease
• C. Vitamin A deficiency
• D. Vitamin D deficiency

Answer: (A)

Iron is essential for making hemoglobin, so when iron stores run low, the body can no longer produce enough healthy red blood cells, leading to iron deficiency anemia. In childhood, growth spurts increase iron needs, and most babies are born with stores that last only a few months depending on birth weight and gestational age. By about six months, many infants require additional dietary iron, and if intake is inadequate or absorption is limited (for example, from excessive cow’s milk), deficiency develops. This combination of high demand during growth and often insufficient intake makes iron deficiency anemia the most common nutritional deficiency in children. Clinically, it can present with fatigue, pallor, and irritability, and labs typically show low ferritin (depleted iron stores), microcytosis and hypochromia (low MCV), and a pattern of high TIBC with low transferrin saturation. Prevention and treatment focus on adequate iron intake through iron-fortified foods, appropriate supplementation for at-risk groups, and monitoring response to therapy. While other deficiencies like vitamin A or vitamin D occur, and anemia of chronic disease reflects inflammation rather than intake, iron deficiency remains the most prevalent nutritional shortfall affecting children.
