The serum selenium levels in 367 healthy adult (25-64 yr) Central Bohemia residents, 176 men and 191 women, were determined using atomic absorption spectrometry. An extremely wide range of values was found in the whole population sample (< 20-296 micrograms/L) as well as in each sex or age category studied. The mean selenium concentration and 95% confidence interval calculated after logarithmic transformation of the data were 74 micrograms/L (71-77) for the whole population sample, 72 micrograms/L (67-76) for men, and 76 micrograms/L (72-81) for women. About 10% of the residents exhibited serum selenium level below 45 micrograms/L. There was no significant correlation between serum selenium and sex, age, or smoking status of participants. However, the lowest average level was found in the group of heavy smoking women: 66 micrograms/L. The selenium status of the Central Bohemia population seems to be below European average. Groups of residents having a very low nutritional selenium intake may be expected to occur in this population.
采用原子吸收光谱法测定了367名（年龄在25 - 64岁之间）中波希米亚健康成年人（176名男性和191名女性）的血清硒水平。在整个人口样本（<20 - 296微克/升）以及所研究的每个性别或年龄组中都发现了极广泛的数值范围。对数据进行对数转换后计算出的整个人口样本的平均硒浓度和95%置信区间为74微克/升（71 - 77），男性为72微克/升（67 - 76），女性为76微克/升（72 - 81）。约10%的居民血清硒水平低于45微克/升。参与者的血清硒与性别、年龄或吸烟状况之间无显著相关性。然而，重度吸烟女性组的平均水平最低：66微克/升。中波希米亚人群的硒状况似乎低于欧洲平均水平。预计该人群中可能会出现营养性硒摄入量极低的居民群体。
