The most obvious sign of vitamin D deficiency in children is?

• A. Dry skin
• B. Rickets
• C. Scurvy
• D. Anemia

Answer: (B)

Rickets, the obvious sign in children, comes from vitamin D deficiency that impairs bone mineralization during growth. Vitamin D helps the gut absorb calcium and phosphate, which are essential for bones to harden properly. When this process is disrupted, growing bones become soft and weak and show recognizable changes such as bowed legs, delayed growth, widening of the wrists and ankles, and sometimes a beaded rib margin (rachitic rosary) or frontal bossing. These skeletal features are far more specific to vitamin D deficiency in kids than other common concerns like dry skin, scurvy, or anemia, which have different causes and presentations.
