为探讨学龄儿童铁营养状况,我们选择位于天津市内营养状况中等的某小学进行普查,以 Hb、Hct、FEP、SF 为指标参照全国标准将缺铁儿童分为 ID、IDE、IDA 三期,304名7～13岁儿童中总缺铁89名(29.3%),ID 组44名(14.5%),IDE 35名(11.5%),IDA10名(3.3%),正常铁营养儿童计215名。正常组,总缺铁各组各指标水平比较可见缺铁组 Hb、Hct、SF 有显著下降的趋势,FEP、FEP/Hb 逐渐增高的趋势。89名缺铁患儿缺铁病因调查表明,这些儿童大多具有不良饮食习惯。突出的是不吃早餐,零食甜食较多,偏食严重。本文建议应重视学龄儿童铁营养状况,宣传普及学龄儿童保健知识,保征足够营养,纠正不良饮食习惯,提倡吃饭定时定量,不吃零食及确实搞好小学校加餐是预防和治疗学龄儿童铁缺乏症的重要步骤。
In order to explore the status of iron nutrition in school-age children, we selected a primary school with medium nutritional status in Tianjin to conduct census. According to the national standards, Hb, Hct, FEP and SF were used to divide iron deficiency children into ID, IDE and IDA. There were 89 (29.3%) of the total 304 iron deficiency in children aged 7-13 years, 44 (14.5%) in the ID group, 35 (IDE) 11.5%, IDA 10 (3.3%) and 215 normal children with iron nutrition. In the normal group and total iron deficiency group, the levels of Hb, Hct, SF in the iron deficiency group showed a significant decrease, while the FEP and FEP / Hb increased gradually in the iron deficiency group. An investigation of the cause of iron deficiency in 89 children with iron deficiency showed that most of these children had poor dietary habits. Prominent is not eating breakfast, snacks and more sweet, partial eclipse serious. This article suggests that we should pay attention to the status of iron nutrition in school-age children, propagandize the health knowledge of school-age children, protect adequate nutrition, correct bad eating habits, promote regular meals, do not eat snacks and do primary school meals to prevent and treat school-age children’s iron deficiency Important step of the disease.
