缺铁性贫血(IDA)是小儿最常见的营养缺乏病之一。由于参与机体代谢的许多酶为含铁酶或铁需要酶,故缺铁时可因多种酶活性降低而导致机体多种代谢紊乱,影响多个器官的功能,如智能,消化吸收功能,肌肉运动功能,免疫功能等。因此,大力开展IDA的防治研究,降低发病率,是保证小儿健康发育 Iron deficiency anemia (IDA) is one of the most common nutritional deficiencies in children. Due to the many enzymes involved in the metabolism of the body iron-containing enzymes or iron need enzymes, iron deficiency can be due to a variety of enzyme activity and lead to a variety of metabolic disorders, affecting multiple organ functions, such as intelligence, digestion and absorption, muscle Sports function, immune function and so on. Therefore, to vigorously carry out prevention and treatment of IDA study to reduce the incidence is to ensure the healthy development of children
