Plasma selenium (Se) concentration and erythrocyte glutathione peroxidase activity (GPx) were assessed in a population of healthy preschool children two to five years old, residing in the city of Paris. In the 118 subjects, mean (+/- SD) plasma Se concentration was 62.10 +/- 13.96 micrograms/L, and mean GPx activity was 23.58 +/- 8.52 U/g Hb. Mean plasma Se of male children was significantly (p = 0.001) higher (12%) than levels of girls. Plasma selenium levels were not correlated with erythrocyte GPx activity. Children from Mediterranean origin had a slightly lower erythrocyte GPx activity (p < 0.05) than children from other regions. Mean plasma Se concentration of this group corresponded to the lower limit of intervals, which characterizes geographical regions of intermediate selenium concentrations.
对居住在巴黎市的2至5岁健康学龄前儿童群体进行了血浆硒（Se）浓度和红细胞谷胱甘肽过氧化物酶活性（GPx）评估。在118名受试者中，血浆硒浓度平均（±标准差）为62.10±13.96微克/升，平均GPx活性为23.58±8.52 U/g Hb。男童的平均血浆硒水平显著（p = 0.001）高于女童（高12%）。血浆硒水平与红细胞GPx活性无相关性。来自地中海地区的儿童红细胞GPx活性略低于其他地区的儿童（p < 0.05）。该组的平均血浆硒浓度对应于中间硒浓度地理区域特征的区间下限。
