Selenium status of the Swiss population: assessment and change over a decade.
A monitoring study of serum selenium concentration was carried out on healthy blood donors from different regions of Switzerland. With an overall mean serum concentration of 98 microg/L (n=1847), the selenium status of the healthy adults can be assessed as adequate. The lowest measured concentration of 62 microg/L denotes that the risk of a marginal selenium deficiency in the Swiss population is small. Compared to a similar study carried out in 1993, the status improved for both genders, although the increase is higher among women. It is noteworthy that the supplementation practice has increased during this period with ca. 2% of the population taking Se-micronutrients. No correlation between the age and the serum concentration is detected, even though the age-range was enlarged in this study to 18-68 years for the women and to 19-72 years for the men. The place of residence only marginally influences the selenium concentration, which implies a certain uniformity of the dietary habits between the various regions of the country.
