世界上最常见的营养缺乏是铁缺乏，而儿童则是一种高危人群。有人提出血清运铁蛋白受体（ＴｆＲ）浓度可准确表明成人铁消耗的程度，但对于儿童的ＴｆＲ却知之甚少。芬兰最近开展了一项旨在证明ＴｆＲ能描述儿童和成人铁状况的研究。观察对象按年龄分为３组：１岁健康婴儿（男
The world’s most common nutritional deficit is iron deficiency, while children are a high-risk population. It has been suggested that the serum transferrin receptor (TfR) concentration accurately indicates the extent of iron consumption in adults, but little is known about the TfR in children. Finland recently conducted a study to demonstrate that TfR can characterize the condition of children and adults. Subjects were divided into three groups by age: 1-year-old healthy infants (male
