Which nutritional deficiency is most commonly found in adolescence?

Correct option is A

Sol. Iron deficiency anemia is the most prevalent nutritional deficiency among adolescents. During adolescence, rapid growth increases the body's demand for iron. Inadequate iron intake during this critical period can lead to anemia, characterized by fatigue, weakness, and impaired cognitive function. Adolescent girls are particularly at risk due to menstrual blood loss.
Explanation of each option:
· (a) Iron Deficiency Anemia – Correct answer. Iron deficiency anemia is the most common nutritional deficiency in adolescents, leading to reduced oxygen transport in the blood and symptoms like fatigue and decreased immunity. ​
· (b) Hypothyroidism – Incorrect. Hypothyroidism is a condition resulting from insufficient thyroid hormone production, not a nutritional deficiency, though it can be influenced by iodine deficiency.​
· (c) Calcium Deficiency – Incorrect. While calcium deficiency can occur during adolescence and affect bone development, it is less common than iron deficiency anemia. ​
· (d) Zinc Deficiency – Incorrect. Zinc deficiency can impair growth and immune function in adolescents but is not as prevalent as iron deficiency anemia.
