Abstract: 【Objective】 To understand the correlation of trace elements and physical development of infants and young children and the risk factors causing malnutrition,intervention measures to ensure the normal development of the infantile. 【Methods】 868 cases of 0 to 2-year-old infants were randomly selected,a comparative study of six kinds of trace elements in the test results of the blood zinc,copper,calcium,iron,magnesium,aluminum and physical development of the measurement results. 【Results】 zinc,iron,calcium deficiency and high blood lead in children with growth retardation were higher than normal infant,and the risk rate are 4.04,3.20,2.61,3.00 times than that of normal children (P<0.05).Zinc,iron,calcium deficiency and high blood lead in children with low body weight were higher than normal infants,and the risk rate are 2.49,4.52,2.46,1.63 times than that of the normal children (P<0.05).Zinc,iron,calcium deficiency and high blood lead in children with malnutrition were higher than normal infants,and the risk rate are 5.02,3.67,2.29,3.82 times than that of normal children (P<0.05).(P<0.05). 【Conclusion】 The physical development of infants and young children are closely associated with the trace elements levels such as zinc,iron,calcium and lead.

摘要： 【目的】 了解婴幼儿微量元素与体格发育的相关性和造成营养不良的危险因素,为制定干预措施提供依据。 【方法】 抽取868例0~2岁婴幼儿血锌、铜、钙、铁、镁、铅检测结果与体格发育测量结果进行比较研究。 【结果】 锌、铁、钙缺乏症和高血铅症患儿生长迟缓的发生率均高于正常婴幼儿,发病风险分别为正常儿童的4.04、3.20、2.61、3.00倍(P均<0.05)。锌、铁、钙缺乏症和铅中毒症患儿低体重的发生率均高于正常婴幼儿,发病风险分别为正常儿童的2.49、4.52、2.46、1.63倍(P均<0.05)。锌、铁、钙缺乏症和铅中毒症患儿营养不良的发生率均高于正常婴幼儿,发病风险分别为正常婴幼儿的5.02、3.67、2.29、3.82倍(P均<0.05)。 【结论】 婴幼儿体格发育与微量元素锌、铁、钙、铅水平有密切相关。
