采用血红蛋白(Hb),红细胞游离原卟啉(FEP)及血清铁蛋白(SF)等多项血液学指标,对六个省区不同民族的学龄前儿童进行了缺铁性贫血患病情况的调查,同时结合膳食组成的调查,分析其与缺铁性贫血患病的关系。结果发现:铁缺乏症平均为59.1％,缺铁性贫血患病率为16.4％,年龄分布以6个月和1岁组最高,分别为28.7％及22.7％。通过膳食组成调查分析,发现不同地区小儿缺铁性贫血患病率与当地的膳食组成有密切关系。除膳食铁外,摄取动物性食品及蛋白质较高的地区,其缺铁性贫血患病率较低。
Hemoglobin (Hb), erythrocyte free protoporphyrin (FEP) and serum ferritin (SF) were used to investigate the prevalence of iron deficiency anemia in preschool children of different nationalities in six provinces and autonomous regions. At the same time, the relationship between diet and iron deficiency anemia was analyzed based on the investigation of dietary composition. The results showed that the average iron deficiency rate was 59.1%, the prevalence of iron deficiency anemia was 16.4%, and the age distribution was highest at 6 months and 1 year old group, which was 28.7% and 22.7% respectively. Through the analysis of diet composition, found that prevalence of iron deficiency anemia in children in different regions and the local diet are closely related. Except for dietary iron, the prevalence of iron deficiency anemia is lower in areas with higher intake of animal foods and protein.
