Abstract

Objective To know about the status of vitamin A deficiency of 4 to 6-year-old children in Dongguan city, and the effects of vitamin A on count and classification of leukocyte. Methods A sampling survey was used to selected healthy children aged 4~6 in this study, and full blood differential counts were determined by blood routine examination,vitamin A concentration were tested by High Performance Liquid Chromatography(HPLC). Results The percentage of vitamin A deficiency was 34.97%(539/1 687). The count of eosinophils, basophils and mononuclear cells of boys was higher than thase of girls. The number of monocytes and lymphocytes decreased with age. The count of lymphocyte in vitamin A deficiency group was less than that of vitamin A normal group in 4-year-old and 6-year-old children. While the count of neutrophils was higher in the vitamin A deficiency group than that of the vitamin A normal group in 5-year-old children. Conclusion The situation of vitamin A deficiency in preschool children in Dongguan city is still serious, and the vitamin A deficiency can affect the count of lymphocyte and neutrophils.
