Abstract:

Calcium deficiency is common in children of different ages, which can primarily be due to insufficient intake of calcium with food, a high need for calcium due to a rapid increase in bone mass, as well as a violation of congenital or acquired mineral metabolism and the development of secondary hypocalcemia. Calcium is an element that is important for the growth and healthy development of a child. Its deficiency causes various diseases in the child's body, with early detection and elimination of calcium deficiency being important in shaping a healthy society.
