Background: Although selenium is one of the nutrients that has an important role in the metabolism of thyroid hormones, it has been investigated in rare studies. This study aimed to evaluate role of selenium deficiency in children and adolescents with acquired hypothyroidism. Methods: This case and control study was conducted on 60 acquired hypothyroidism and 60 healthy children who had been referred to the pediatrics endocrine clinic in Shiraz, Iran, from November 2018 to April 2019. Some information such as age, gender, weight, height, duration of disease, and level of plasma selenium were recorded. Plasma selenium level was measured by atomic absorption spectrophotometer. Data were analyzed using SPSS software 21.0. Results: The mean of selenium level in the case and control groups were 93.77 ± 24.90 μg/dl and 85.96 ± 25.20 μg/dl, respectively. There was no significant difference between the two groups in the mean levels of selenium. Independent t-test showed no significant difference in the mean levels of selenium in male and female samples in the case group, but this difference was significant in the control group. Conclusion: Selenium deficiency may not have significant role as a cause of acquired hypothyroidism in pediatric and adolescent age group, in south of Iran. Thus, it does not seem necessary to routinely check the level of selenium for patients with thyroid dysfunction.
