In toddlers, which nutrition concern is commonly screened for?

• A. Vitamin K deficiency.
• B. Iron deficiency anemia due to inadequate iron intake.
• C. Vitamin C deficiency.
• D. Iron overload.

Answer: (B)

Iron status screening in toddlers focuses on iron deficiency anemia, which is a common nutritional issue in early childhood. Iron is essential for oxygen transport and brain development, and toddlers are at risk because growth is rapid while diets often shift away from iron-rich foods. High cow’s-milk consumption, limited intake of iron-rich foods, and picky eating can all contribute to not meeting iron needs. When iron deficiency develops, it can lead to fatigue, pallor, irritability, poor growth, and potential impacts on cognitive development if not addressed. Early detection allows simple, effective treatment with dietary changes and iron supplementation.

Screening typically uses a simple blood test to measure hemoglobin or hematocrit, with ferritin or other iron studies added if iron deficiency is suspected. Other nutritional deficiencies like vitamin K or vitamin C deficiency are not routinely screened in healthy toddlers, and iron overload is not a common concern in this age group.
