Abstract: Iodine deficiency has been shown to have high prevalence in Iran despite sufficient iodine supplementation. Zinc deficiency may also contribute to the pathogenesis of endemic goiter. The aim of this study was to compare serum zinc level in Iranian school children with and without goiter. A cross-sectional study was performed among urban children aged 8–12 years in city of Kerman, Iran. A multistage proportional to size cluster sampling method was used to screen 5500 subjects out of 29,787 students. After the screening phase, serum and urine specimens of randomly selected 165 students were evaluated for serum zinc levels and urinary iodine excretion and compared in goiterous and non-goiterous children. Serum zinc level was 149.5±29.4μg/l in goiterous children and 141.2±52μg/l in non-goiterous children but no significant difference was found between the groups (p =0.37). But urinary iodine excretion was significantly (p <0.001) lower in goiterous children (207.5μg/l in goiterous children and 262.5μg/l in non-goiterous children). This study showed that serum zinc level in goiterous and non-goiterus children is not different and zinc deficiency is not a risk factor for endemic goiter in this population.
