Abstract: Objective To examine the effects of children's nutrition condition of zinc (Zn) and iron(Fe) on status of immunization indicators.Methods A total of 1 023 students of 1-6 grades were investigated about their general state of health,5 days diet and 1 month food frequency,recurrent respiratory tract infection (RRTI) status and 262 children's immune indicators were determined after informing the consent to their parents.Results The average intakes of Zn,Fe were 60%-80% of the recommended nutrient intake (RNI) and the rates of adequate intake(AI) were 20%-30%.The intake of Fe was adequate,but only 9.9% of the Fe was from heme-iron.The results of immunization indicators detects showed that the percentages of CD3⁺ cells,the ratio of CD4⁺/CD8⁺,IgA,and IgM were all below the reference value among the students.The incidence of RRTI was 12.6 %.The CD4⁺,CD4⁺/CD8⁺,IgA and IgM were at the normal level for the students with the Zn intake level of ≥80% OF RNI or the Fe intake level of ≥200% OF AI.Conclusion The intakes of Zn and hme-iron were lower for the most of the students.The studetns immune levels are normal when their Zn intake ≥80% of RNI or their Fe intake ≥200% of AI.
