Selenium is one of the essential trace elements which is more notified in children in recent years. Reliable age-specific reference values for selenium in children in Iran are not clear and are important for the identification of selenium deficiency and some other researches that is the aim of this study.
Serum samples of 216 healthy children were analyzed by using hydride generation and flame atomic absorption spectroscopy to measured selenium level.
The mean and standard deviation of serum selenium level in children 0-16 years old (mean: 39.83 months) was 72.14+/-16.80 microg/l. There was significant difference in serum selenium concentration between two sexes which was 76.78+/-15.24 microg/l and 69.56+/-17.09 microg/l in girls and boys respectively (P value=0.002). There was also a positive correlation between higher selenium serum concentration and age in both sexes.
Essential trace element's normal ranges are fundamental data which could use in many studies. Serum selenium concentration in healthy Iranian children that found in this study is very close to serum concentration of European children. Our findings may reveal nutritional culture's similarity.
硒是近年来在儿童中更受关注的必需微量元素之一。伊朗儿童硒的可靠年龄特异性参考值尚不清楚，而这对于识别硒缺乏及其他一些研究很重要，这也是本研究的目的。
采用氢化物发生-火焰原子吸收光谱法对216名健康儿童的血清样本进行分析，以测定硒水平。
0至16岁儿童（平均年龄：39.83个月）血清硒水平的平均值及标准差为72.14±16.80微克/升。两性之间血清硒浓度存在显著差异，女孩和男孩的血清硒浓度分别为76.78±15.24微克/升和69.56±17.09微克/升（P值=0.002）。两性中血清硒浓度较高者与年龄之间也存在正相关。
必需微量元素的正常范围是可用于许多研究的基础数据。本研究中发现的健康伊朗儿童的血清硒浓度与欧洲儿童的血清浓度非常接近。我们的研究结果可能揭示了营养文化的相似性。
