目的：探讨亚临床状态维生素A（VA）缺乏与小儿反复呼吸道感染的关系。方法：采用高效液相色谱测定了253例学龄前儿童的血清VA含量，其中129例为复感患儿，124例为健康儿童，分别比较了两组儿童各年龄组的血清VA含量。结果：复感患儿的血清VA含量各年龄组均低于健康儿童（P＜0．01～0．05）；复感患儿中亚临床状态VA缺乏有39例（30．2％），健康儿童中有9例（7．3％），前者的亚临床状态VA缺乏的发生率明显高于后者（P＜0．005）。结论：亚临床状态VA缺乏与反复呼吸道感染有密切关联。
Objective: To investigate the relationship between subclinical vitamin A (VA) deficiency and recurrent respiratory tract infections in children. Methods: Serum VA levels of 253 pre-school children were determined by high performance liquid chromatography. Among them, 129 were children with complex symptoms and 124 were healthy children. Serum VA levels were compared between two groups of children in each age group. Results: The serum VA level in children with sepsis was lower in all age groups than in healthy children (P <0.01 ~ 0.05). There were 39 (30.2%) VA patients with seizures in Central Asia, Nine of the healthy children (7.3%) had a significantly lower incidence of subclinical VA deficiency (P <0.005). Conclusion: VA deficiency in subclinical state is closely related to recurrent respiratory tract infection.
