INTRODUCTION In order to address population-level mild iodine deficiency in Australia, a mandatory iodine fortification programme of salt used in bread was introduced in late 2009. METHODS A before-after study was conducted to assess changes in median urinary iodine concentration (MUIC) measurements, according to supplement use, in convenience samples of pregnant women attending a public antenatal clinic in a regional area of New South Wales, Australia in 2008 (n=139), 2011 (n=147) and 2012 (n=114). Knowledge and practices related to iodine nutrition were investigated in 2012, using self-administered questionnaires. RESULTS The mild iodine deficiency confirmed pre-fortification (MUIC (IQR)=87.5 (62-123.5; n=110)) has steadily improved to 145.5 μg/L (91-252) in 2011 (n=106) and 166 (97-237) in 2012 (n=95) (sufficiency ≥ 150 μg/L). However, only women taking supplements containing iodine had MUIC indicative of sufficiency in both years surveyed post fortification (2011: 178 μg/L vs. 109 μg/L, P<0.001; 2012: 202 μg/L vs. 124 μg/L, P<0.05). Despite bread being the vehicle for iodine fortification, dairy foods remained major contributors to total iodine intake (58%). Overall knowledge regarding health implications of iodine deficiency was poor. CONCLUSIONS Iodine status of women has improved since the introduction of mandatory iodine fortification; however supplementation is indicated during pregnancy.

Dietary Iodine Intake of the Australian Population after Introduction of a Mandatory Iodine Fortification Programme

To address mild iodine deficiency in Australia, a mandatory fortification program of iodised salt in bread was implemented in 2009. This study aimed to determine factors associated with achieving an adequate dietary iodine intake in the Australian population post-fortification, and to assess whether bread consumption patterns affect iodine intake in high-risk groups. Using nationally representa...

OBJECTIVE To identify a level of iodine supplementation to recommend for pregnant and breastfeeding women in Australia. DESIGN, SETTING AND PARTICIPANTS Dietary modelling indicated that mandatory fortification of bread with iodine by replacing salt with iodised salt would still leave a gap in iodine intakes in pregnant and breastfeeding women in Australia. Iodine shortfall was estimated by tw...
