对88例婴幼儿(其中70例主要为母乳喂养)体内叶酸、维生素 B_(12)、铁的含量及其与营养性贫血、喂养方式、辅食添加及乳母的饮食结构的关系进行了初步探讨,结果发现:(1)本文88例≤2岁小儿贫血患病率高达85.22%(75/88),其中与叶酸缺乏及铁缺乏有关的营养性贫血占72%(54/75)。(2)营养性贫血的发病高峰期为出生后7～12个月。(3)营养供给不足是造成婴幼儿营养性贫血发病率高的原因。而造成营养供给不足的原因主要是缺乏科学育儿及营养知识。
The content of folic acid, vitamin B 12 and iron in 88 infants and young children (70 of them are mainly breastfeeding) were studied. The relationship between the content of folic acid and iron, nutritional anemia, feeding mode, dietary supplement, The results showed that: (1) The prevalence of anemia in 88 cases ≤2 years old was 85.22% (75/88), 72% (54/75) were associated with folic acid deficiency and iron deficiency. (2) The peak incidence of nutritional anemia is 7 to 12 months after birth. (3) lack of nutrition is the cause of high incidence of nutritional anemia in infants and young children. The main reason for the lack of nutrition supply is the lack of scientific childcare and nutrition knowledge.
