Mein Nair Zinc Level in Children with Idiopathic Short Stature in Isfahan

Zinc deficiency may Cause growth failure and short stature . The purpose of this study is the comparison between hair zinc level in short children and a control group . This descriptive - analytical study was done on 35 short children of 4-17 years old referring to the pediatric endocrinology Center of Isfahan in 1379 . The hair Samples were prepared from occipital region and were sent to the Central laboratory of Miniatore - Neutron - Source - reactor (MNSR) and zinc concentration measured by Neutron - Activation - Analysis (NAA) Method . Zine deficiency is defined as hair zinc level <110 PPm . Mean hair zinc level in short children was 144.734.3.4 PPM and in Control group was 133.7738.85 PPm . Mean hair zinc level in short boys was 131.4247.35 PPm and in short girls was 183.1149.05 PPm (P=0.009) . Therefore , it seems that zinc deficiency isnʹt a prominent etiology of short stature , and probably other etiologic factors , genetic factors and unknown etiologies may exist which are worth evaluation .
