New study finds iodine deficiency in UK pregnant women

A new study, published in Nutrients, has found that pregnant women from three UK cities (London, Leeds and Manchester) were classified as iodine deficient. The study included measures of iodine status from 541 pregnant women from 2004-2008. The median urinary iodine concentration was between 116 and 139 mcg/L, which is below
the WHO cut-off for sufficiency of 150 mcg/L.
