儿童少年正处在生长发育突增时期,表现在形态、生理、生化和内分泌等发生一系列巨大的变化。铁需要量相对增加,但常因摄入不足、吸收不良、损失过多而导致IDA(缺铁性贫血)的发生。IDA又名营养性小细胞贫血,是儿童贫血中最常见的一种,约占儿童贫血的80％。据文献报道,世界各地儿童中贫血的患病率在30～90％,即使在经济发达的欧美国家中也不少见。因此,儿童少年的IDA仍是当前各国普遍关注的问题。
Children and adolescents are in the period of rapid growth and development, showing a series of huge changes in morphology, physiology, biochemistry and endocrine. The relative increase in iron demand, but often due to inadequate intake, malabsorption, excessive loss of IDA (iron deficiency anemia). IDA, also known as nutritional small cell anemia, is the most common form of childhood anemia, accounting for about 80% of children’s anemia.
