To the Editor: Rahman and colleagues suggest that iodine deficiency in Victoria increased between 2001 and 2006, based on the findings of thyroid-stimulating hormone (TSH) levels in neonates at routine newborn screening.1 Indeed, their data as presented suggest a doubling of the percentage of mothers with iodine deficiency to over 9% during that period. This could be correct. Certainly, as they state, there is much evidence to suggest that there is mild iodine deficiency in Australia. However, there are caveats about the data they report which are not mentioned.
