目的:调查沿海地区学龄前儿童铁减少(ID)、缺铁性贫血(IDA)及铁缺乏症(ID+IDA)患病率。方法:采用分层抽样的方法,以城市、农村为调查点,随机抽取1382例学龄前儿童为调查对象,检测末梢血血红蛋白浓度、锌原卟林、血清铁蛋白等指标。结果:学龄前儿童ID、IDA、铁缺乏症(ID+IDA)患病率分别为25.8%、4.9%、32.9%。农村学龄前儿童ID、IDA患病率为21.8%、6.9%、IDA者Hb(102.4±6.9)g/L,城市学龄前儿童ID、IDA患病率为29.6%、2.1%、IDA者Hb(105.8±4.1)g/L。城市学龄前儿童ID患病率显著高于农村(P<0.05),农村学龄前儿童IDA患病率明显高于城市,且血红蛋白浓度低于城市(P<0.05),城市学龄前儿童铁缺乏症患病率为30.7%,农村学龄前儿童铁缺乏症患病率为35.0%,农村与城市无显著差别(P>0.05)。结论:学龄前儿童铁缺乏症是沿海地区普遍存在的问题,城市以隐性缺铁多见,缺铁程度较轻;农村缺铁程度重,贫血为突出表现。
PURPOSE: To investigate the prevalence of iron deficiency (ID), iron deficiency anemia (IDA) and iron deficiency (ID + IDA) in preschool children in coastal areas. Methods: By stratified sampling method, taking urban and rural areas as survey points, 1382 preschool children were randomly selected as the investigation object to detect the indexes of peripheral blood hemoglobin, zinc protoporphyrin and serum ferritin. Results: The prevalence rates of ID, IDA and iron deficiency (ID + IDA) in preschool children were 25.8%, 4.9% and 32.9% respectively. The prevalence of IDA in rural areas was 21.8% and 6.9% for IDA patients, 102.4 ± 6.9 g / L for IDA patients, 29.6% for urban preschool children and 2.1% for IDA patients 105.8 ± 4.1) g / L. The prevalence of ID in urban preschool children was significantly higher than that in rural areas (P <0.05). The prevalence of IDA in rural preschool children was significantly higher than that in urban areas, and the hemoglobin concentration was lower than that in urban areas (P <0.05) The prevalence was 30.7%. The prevalence of iron deficiency in rural preschool children was 35.0%. There was no significant difference between rural and urban (P> 0.05). CONCLUSION: Iron deficiency in preschool children is a common problem in coastal areas. In cities, recessive iron deficiency is more common and iron deficiency is less. Rural iron deficiency and anemia are prominent manifestations.
