Abstract
Background and Objective: With regard to high prevalence of attention deficit hyperactivity disorder (ADHD) and its being significantly affected by nutritional factors, we aimed to determine the relationship between zinc serum level and ADHD.
Material and Methods: This ex-post- facto (causal comparative research) design study was conducted on 60 children, selected via convenience sampling. Thirty of them were ADHD children diagnosed by a psychiatrist using DSM IV checklist, as a case group, and the rest were healthy ones located in control group. Having their family informed consent, their Zinc level was measured via Colorimetric method.
Results: The results show that Zinc serum level of ADHD children are lower than that of healthy ones. Using t- test, it was indicated that the difference is not significant. Besides, the result of Pearson correlation coefficient showed that there is no significant relation between Zinc and ADHD.
Conclusion: given that the zinc level was lower in ADHD children, the difference was not significant. Therefore, we recommend conducting further research with a larger sample size.

Abstract
background:
Bivalent minerals have an important role as cofactors which play vital roles in various metabolic pathways in the body. Zinc (Zn) has catalytic, structural, and regulatory roles. Severe Zn deficiency may cause the abnormal synthesis of nucleic acids, and proteins, impaired cellular growth, excessive cell death, and excess lipid peroxidation of the cellular membrane that is associated with shortening the RBC lifespan.
Purpose:
The aim of this study was to examine the associations between Zn status and the erythrocyte indices.
Methods and materials:
A number of 563 individuals (72.8% female) were included in this study. The level of serum Zn was measured by photometric method and blood index values were measured by using a cell counter.
Results:
The average serum Zn level is 102.8± 17.6 mg/dl. Serum Zn level is directly related with RBC (R=0.119, PV=0.005) and MCHC (R=0.086, PV=0.041) but it is inversely related with MCV (R=-0.097, PV=0.021). These results also determined that serum Zn level, as well as the levels of RBC, Hb, HCT, and MCHC, were significantly higher in men (Sig<0.01) but the level of MCV among women was higher (Sig<0.01). Moreover, in individuals with <30 serum Zn level, MCHC (Sig<0.01), and RBC (Sig<0.05) were higher whereas Hb (Sig<0.05), HCT, MCV, and MCH (Sig<0.01) were higher at >30.
Conclusion:
According to the positive relationship between Zn level and RBC, Zn deficiency affects the number of RBCs.
