摘要
为了解维生素A(VA)缺乏与锌的关系,测定215例重庆市远郊区学龄儿童血清VA及95例儿童血清锌,结果发现学龄期儿童低血清VA(≤1.04μmol/L)占49％,低血清锌(<11.5μmol/L)占12％,VA和锌同时低占6％;VA缺乏组与对照组比较血清VA明显降低,血清锌无差别。结果提示本组学龄期儿童VA缺乏主要与摄入不足,体内VA贮存不足有关,与锌影响较少关系.
To study the relationship between vitamin A deficiency and lever of serum zinc,serum VA of 215 and serum zinc of 95 children of school age (CSA) in suburb of Chongqing city were investigated. The results showed low serum VA(≤l. 04μmol/L) and low serum zinc (<11.5μmol/L) in CSA were 49% and 12% respectively, both serum VA and zinc were low in 6% CSA. Compared with the control group .there was significantly de-creaed serum VA and normal serum zinc in VA deficient group. The results suggest that VA deficiency in CSA be caused by low VA diet and livel store and not related with level of serum zinc
