After doing necessary examinations and recording the information, 5 cc of blood was drawn from children. The samples were sent to the chemistry college of S&B university and serum zinc levels were measured by spectrometry method of atomic absorption. The obtained information was analyzed using SPSS software and Fisher test.Results : In this research on 460 children, 232 (50.43%) were boys and 228 (49.56 %) were girls. The average age was 2.5 years. Zinc deficiency was confirmed in 89.3 % of children who had mild malnutrition and all of children who had moderate or severe malnutrition had zinc deficiency.Conclusion : This research indicated that serum zinc levels in most of children with malnutrition was less than standard , and the more severe the malnutrition, the lower the serum zinc levels will be. 100% of the girls and 85.77% of the boys had zinc deficiency.
