目的：调查学龄前、后儿童血清铁蛋白（ＳＦ）含量状况，以便能诊断早期缺铁性贫血，使其及早得以治疗，从而促进儿童的正常发育。方法：采用放射免疫分析技术（ＲＩＡ），将１６３例学龄前、后（包括幼儿园和小学１－５年级学生）儿童按所处环境分为市区组和郊县组进行血清ＳＦ测定。结果：调查发现市区组儿童血清ＳＦ含量明显低于郊县组儿童（低１３．６６％）；在１６３例中有１９例血清Ｔ值＜１４ｎｇ／ｍｌ（占１１．６６％），且市区组中有１１例ＳＦ值＜１２ｎｇ／ｍｌ，而其它贫血指标均正常的隐性贫血患儿（占６．７５％）。不同年龄血清ＳＦ含量无明显差异（Ｐ＞０．０５）。另外，有１０％的儿童血缘基本正常，但其ＳＦ值均＜１２ｎｇ／ｍｌ，经服用铁剂后１个月复查，血清ＳＦ值均＞１４ ｎｇ／ｍｌ。结论：调查学龄前、后儿童血清ＳＦ含量状况，对早期诊断缺铁性贫血或隐性贫血及观察服用铁剂治疗效果，进而促进儿童的正常发育是很有必要的。
Objective: To investigate the status of serum ferritin (SF) in pre-and post-preschool children in order to diagnose early iron-deficiency anemia and to treat it early so as to promote the normal development of children. Methods: 163 cases of pre-and post-preschool children (including kindergarten and pupils in grade 1 to grade 5) were divided into urban district group and suburban county according to their environment to perform serum SF determination by radioimmunoassay (RIA). Results: The survey found that serum SF level in urban children was significantly lower than that in suburban children (13.66%); in 163 cases, 19 cases had serum T values <14ng / ml (11.66%), Eleven patients with a SF value of <12 ng / ml in the regional group, while other children with anemia with normal anemia (6.75%). There was no significant difference in serum SF content between different ages (P> 0.05). In addition, 10% of children with basic blood normal, but the SF value of <12ng / ml, 1 month after taking iron review, serum SF values were> 14ng / ml. Conclusion: It is necessary to investigate the status of serum SF in preschool children and post children in early diagnosis of iron deficiency anemia or latent anemia and iron treatment.
