摘要

Background To assess the selenium status of a group of schoolchildren from the Region of Madrid, Spain. Methods Study subjects comprised 483 children (216 boys and 267 girls) aged between 8 and 13?years. Selenium intake was determined using a 3-day food record. The foods consumed were transformed into energy and nutrients, and the selenium intake was compared with that recommended. Serum selenium levels were also recorded. Results Mean (SD) selenium intake [91.0?(25.2)?μg?day?1] was above the recommended level in 99.4% of subjects; the main dietary sources were cereals, meats, fish and milk products. The serum selenium concentration [mean (SD) 71.1?(14.4)?μg?L?1], however, was <60?μg?L?1 in 13.9% of subjects, and <45?μg?L?1 in 5.6%. The serum selenium concentration correlated with the selenium intake (r?=?0.169; P?
