目的:探讨儿童保健门诊0～2岁婴幼儿体内血液中钙及微量元素锌、铁等含量,并对其结果进行分析。方法:应用日本生产的日立7170A对783例0～2岁儿保门诊婴幼儿进行静脉血(股静脉、肘静脉)中的钙、锌、铁含量检测并进行分析。结果:0～3月组、3～6月组婴儿锌、铁值含量接近;6～12月龄婴儿0值变化较大,可能与喂养方法、营养状况有关;12～24月龄幼儿组血锌值接近标准值,血钙值仍较标准值低。12～24月龄幼儿发生缺钙率在同龄者中约为34.5%,男女童间钙、锌、铁的含量差异无统计学意义。结论:提示婴幼儿各年龄组(以“月”为单位)不同,微量元素的含量不同,各年龄段婴幼儿饮食结构不同,摄入的微量元素也不同,建议细分到月龄制定参考值。
Objective: To explore the contents of calcium and trace elements such as zinc and iron in infants and young children aged 0 ~ 2 years old in child health clinic and analyze the results. Methods: Hitachi 7170A manufactured in Japan was used to detect and analyze the contents of calcium, zinc and iron in 783 infants and young children aged 0 ~ 2 years old. Results: The contents of zinc and iron in infants from March to June in 0 ~ 3 month group were close to each other. The 0 value of infants in 6 ~ 12 months old varied greatly, which may be related to the feeding method and nutritional status. The blood of 12 ~ 24 months old group The zinc value is close to the standard value, and the blood calcium value is still lower than the standard value. The calcium deficiency rate of children aged 12-24 months was about 34.5% in the same age group, and there was no significant difference in the contents of calcium, zinc and iron between boys and girls. Conclusion: It is suggested that the infants and young children have different levels of trace elements in different age groups ( “month ”). The dietary structure of infants and young children in different age groups is different, and the intake of trace elements is also different. Reference.
