Since 1992, the Australian Centre for Control of Iodine Deficiency Disorders (ACCIDD) has performed surveys of Urinary Iodine Excretion (UIE) levels in Australia. It was initially found in 1992 the UIE levels in the Australian population were above 200g/L – a sufficient Iodine level according to the World Health Organisation standards. However, a noticeable trend has been observed in recent years. Median UIE levels were found to be < 100g/L in studies from Victoria, New South Wales and Tasmania, with pregnant women found to have an UIE well below 100g/L. These studies indicated half of these women in NSW, Victoria and Tasmania are Iodine deficient.
The National Iodine Study, conducted in February 2006, has found overall children in mainland Australia are borderline Iodine deficient. A national median UIE level was found to be 104g/L. On a state basis, NSW and Victorian children are mildly Iodine deficient, with median UIE levels of 89g/L and 73.5 g/L, respectively. South Australian children are borderline Iodine deficient, with a median UIE level of 101 g/L. Both Queensland and Western Australia children are Iodine sufficient, with median UIE levels of 136.5 g/L and 142.5 g/L, respectively. It was found about half (46.3%) of all the students tested in mainland Australia had UIE levels in the range of mild (36.7%) to moderate (9.6%) Iodine deficiency. Victoria and New South Wales had the highest percentage of children in the range 20 – 49 g/L (18.8% and 13.6%, respectively).
