Iodine deficiency in UK schoolgirls.

摘要

In a cross-sectional survey of UK schoolgirls aged 14-15 years, Mark Vanderpump and colleagues1 found a median urinary iodine concentration (UIC) of 80-1 ug/L A value less than 100 u.g/L indicates iodine deficiency in that group or population with the severity of the iodine deficiency being determined by three categories of UIC (ie, 50-99 u.g/Lfor mild, 20-49 |ig/L for moderate, and <20 mu.g/Lfor severe); the use of the word "group" is a key point.
