目的:分析儿童血清维生素A水平,并为控制维生素A缺乏提供研究依据。方法:以2013年至2016年进行体检的684例儿童作为研究对象,根据儿童的年龄将其分为婴儿组(1岁以下)94例、幼儿组(1~3岁)102例、学龄前儿童组(4~6岁)189例、学龄儿童组(7~9岁)164例以及青春期组(10~14岁)135例。分别对其维生素A水平进行检测。结果:不同年龄儿童的维生素A水平之间的差异较小,不具有统计学意义。随着儿童年龄的增长,出现维生素A缺乏的概率也会相应降低,但是不能忽视维生素A边缘缺乏的情况。结论:维生素A缺乏的情况仍然较为常见,且出现维生素A缺乏的情况与很多因素有关,要想改善维生素A缺乏的情况就要根据实际情况,适当增加维生素A含量较高的食物或者药物从而达到提升儿童维生素A水平的目的。
Objective: To analyze the level of serum vitamin A in children and provide the basis for the control of vitamin A deficiency. Methods: A total of 684 children from 2013 to 2016 were divided into infants (under 1 year old), 94 infants (aged 1 to 3 years), 102 infants (1 to 3 years old), preschool children There were 189 cases in group (4-6 years old), 164 cases in school-age children (7-9 years old) and 135 cases in adolescent group (10-14 years old). Their vitamin A levels were tested. Results: There was no significant difference in vitamin A levels between children of different ages. As children grow older, there is a corresponding reduction in the risk of vitamin A deficiency, but the lack of vitamin A margins can not be overlooked. Conclusion: The situation of vitamin A deficiency is still more common, and the situation of vitamin A deficiency is related to many factors. If we want to improve the deficiency of vitamin A, we should appropriately increase the foods or drugs with higher vitamin A content according to the actual situation The purpose of raising children’s vitamin A level.
