为了确定没有贫血(血红蛋白,Hb>11g/dl)但有缺铁表现的婴儿可能存在着行为发育的改变,作者筛查了306例9～12个月健康婴儿的铁营养状况(其中缺铁性贫血占8.2%,贮存铁减少占16.1%),并从中选取38例(男19,女19)无早产、新生儿期无窒息、无慢性病和先天畸形,Hb≥11g/dl但有不同程度缺铁的婴儿,分为下列4组: 组1:铁充足组,10例。Hb≥11g/dl,游离红细胞内原卟啉(FEP)<30μg/dl,血清铁蛋白(SF)>12ng/ml,红细胞平均容积(MCV)≥70fl。组2:贮存铁减少组,10例,Hb≥11g/dl,FEP<30μg/dl SF<12ng/ml,MCV≥70 fl 组3:铁缺乏组,10例,Hb≥11g/dl,FEP>30μg/dl SP<12ng/ml,MCV≥70fl 组4:铁缺乏组,8例,Hb≥11g/dl,FEP>30μg/dl SF<12ng/ml,MCV<70fl
To determine the possible behavioral changes in infants with anemia but not anemia (hemoglobin, Hb> 11 g / dl), the authors scrutinized the nutritional status of iron in 306 healthy infants aged 9 to 12 years (of which iron deficiency Anemia accounted for 8.2%, iron storage reduction accounted for 16.1%), and from the selection of 38 cases (19 male and 19 female) without premature birth, no asphyxia in neonatal period, no chronic diseases and congenital malformations, Hb≥11g / dl but with varying degrees of lack Iron infants, divided into the following 4 groups: Group 1: iron sufficient group, 10 cases. Hb≥11g / dl, free erythrocyte protoporphyrin (FEP) <30μg / dl, serum ferritin (SF)> 12ng / ml and average volume of erythrocytes≥70fl. Group 2: iron reduction group, 10 cases, Hb≥11g / dl, FEP <30μg / dl SF <12ng / ml, MCV≥70 fl group 3: iron deficiency group, 10 cases, Hb≥11g / dl, FEP> 30μg / dl SP <12ng / ml, MCV≥70fl group 4: iron deficiency group, 8 cases, Hb≥11g / dl, FEP> 30μg / dl SF <
