Abstract: Objective To study the correlation between the in takes of vitam in A,C,E and the immunization indicators among childeren.Methods The five days diet and one month food in take frequency of 293 primary school children were investigated.Plasm a vitamin,T-lymphocyte subsets and serum IL-2,IgG,IgM,IgA,complement C₃ were determined in 262 of the children.Results The children's in takes of vitam in A,C,E have a positive correlation with plasma levels of vitamins.The average intakes of vitam in A,C were lower than recommended in take(RNI)with inadequate rates of 52.62% and 35.59%.The rates of deficiency and marginal deficiency for vitam in A were 11.1% and 29.0%;that of for vitam in C were 15.3% and 21.4%.Although the vitam in E intakes in children was high,there were still 9.92% of the children with the plasma level lower than the normal range.The percen tages of CD₃⁺ cells,the ratio of CD₄⁺ /CD₈⁺,as well as IL-2,IgA were below the reference value.The rates of lowere level CD₃⁺,CD₄⁺,CD₄⁺ /CD₈⁺,IL 22,as well as IgG,IgA,C₃ than the refernce value were 29.141%,54.96%,22.14%,37.79%,17.18%,22.25% and 5.73%,respectively.The CD₈⁺,IgM levels higherthan the reference value were observed in 23.66% and 12.60% of the children.The childrenπs intakes of vitam in A had positive relations with IL-2,CD₄⁺,IgG,CD₄⁺ /CD₈⁺,and negative relation with IgM.The in takes of vitam in C had positive correlation with CD₃⁺ CD₄⁺ /CD₈⁺,IgA,negative relation with IgM.The in takes vitam in E had positive relations with IL-2,CD₄⁺,and IgG.Conclusion The children's in takes of vitam in A,C are inadequate.The in takes of vitam in A,C,E have corre lations with levels on immune function.
