关于美国人群血清硒水平的已发表文献描述了可能不代表美国人群的小样本研究。这项分析提供了第一个全国代表性的血清硒水平在美国人口的年龄组，性别，种族，贫困收入比（PIR），地理区域和城市地位。第三次全国健康与营养检查调查（NHANES III）是一项以全国人群为基础的横断面调查，包括面对面访谈和血清硒测定，在NHANES III中有血清硒值的18，597人中，平均浓度为1.58 nmol/L，中位数浓度为1.56 nmol/L。平均血清硒水平不同的年龄组，性别，种族，民族，PIR，和地理区域。由于人口统计因素，美国人群的血清硒水平略有差异。
The published literature on serum selenium levels in the US population describes studies on small samples that may not be representative of the US population. This analysis provides the first nationally representative serum selenium levels in the US population by age group, sex, race-ethnicity, poverty income ratio (PIR), geographic region, and urban status. The Third National Health and Nutrition Examination Survey (NHANES III) is a national population-based cross-sectional survey with an in-person interview and serum selenium measurements.For the 18,597 persons for whom serum selenium values were available in NHANES III, the mean concentration was 1.58 nmol/L and the median concentration was 1.56 nmol/L. Mean serum selenium levels differed by age group, sex, race-ethnicity, PIR, and geographic region. The US population has slight differences in serum selenium levels by demographic factors.
