Abstract：

Iron is an important element that maintains the normal operation of the body. It not only participates in various physiological reactions as a component of various enzymes, but also is an indispensable component in the synthesis of hemoglobin (Hb) and myoglobin, which transport oxygen. About two-thirds of the iron in the body is stored in the Hb of red blood cells, with a small amount present in myoglobin in muscle tissue and enzymes required for various metabolic reactions. The remaining amount is mostly in the form of ferritin as a mobilized iron reserve. When dietary iron intake is limited and the stored iron in the body is insufficient or depleted, iron deficiency occurs. Iron deficiency can be further divided into three stages based on their severity, namely iron deficiency (ID), iron deficiency erythropoiesis (IDE), and iron deficiency anemia (IDA). This study aims to explore the prevalence, diagnosis and differentiation, influencing factors, and preventive interventions of iron deficiency.
