“…Previous studies in New Zealand, the United Kingdom, and Australia have also found that pregnant and lactating women have little knowledge about iodine [20,23,25]. In line with these studies, participants had difficulties identifying the most important dietary iodine sources.…”

“…In these studies, women had difficulties identifying important dietary sources of iodine as well as adverse health outcomes related to iodine deficiency. For instance, only half of the participants in cross-sectional studies among pregnant women in Australia correctly identified seafood as a good source of iodine and more than half of the participants could not identify any adverse health problem related to iodine deficiency [20,25]. Women’s age and educational level may influence their knowledge about iodine [23].…”

Background: Lack of knowledge about iodine may be a risk factor for iodine deficiency in pregnant and lactating women. The aim of this study was to assess knowledge about iodine and predictors of iodine knowledge scores among pregnant and lactating women. The study also examined whether iodine knowledge scores were associated with iodine status. Methods: A cross-sectional study was performed on 804 pregnant women and 175 lactating women from 18 to 44 years of age in 2016 in the Oslo area, Norway. Knowledge about iodine was collected through a self-administered, paper-based questionnaire. Iodine concentrations in urine and breast milk were measured using an inductively coupled plasma mass spectrometer (ICPMS). Results: 74% of the pregnant women and 55% of the lactating women achieved none to low iodine knowledge scores. Higher educated pregnant women and those who had received information about iodine had significantly higher knowledge scores. In lactating women, increased age was associated with higher knowledge scores. Knowledge scores were not associated with participants’ iodine status. Conclusion: This study revealed a lack of knowledge about the importance of iodine in pregnant and lactating women, as well as about the most important dietary sources. Public education initiatives are required to increase the awareness about iodine in these population groups.

“…To the best of our knowledge, no published studies have assessed adherence to the PFS recommendation in a national sample of Australian women or the adherence to the more recent NHMRC recommendation regarding IS. There is only one Australian study, of 200 women in Victoria, that has examined adherence to the NHMRC's IS recommendation during pregnancy, 13 with other studies in NSW assessing use of iodine‐containing supplements during pregnancy but not adherence to the recommendation 14–16 . National data is also lacking with regards to pregnant women's knowledge of supplement recommendations and associations between knowledge and adherence.…”

Objective: To determine pregnant women's knowledge of and adherence to the recommendations for periconceptional folic acid supplementation (PFS) and iodine supplementation (IS). Secondary objectives include determining predictors of adherence, and identifying influential nutrition information sources. Methods:A cross-sectional online survey was completed by 857 pregnant women, including a national cohort (n=455) recruited using an online panel provider and a South Australian cohort (n=402) recruited from a public maternity hospital.Results: Adherence to PFS and IS recommendations was 27% and 23%, respectively. Planning pregnancy and awareness of the correct timing of recommendations were predictors of adherence for both recommendations. Not consuming any alcohol during pregnancy and living in metropolitan areas also predicted adherence to the IS recommendation. Awareness of the recommendation was greater for folic acid (more than 90%) than iodine (56-69%). Knowledge of the importance of folic acid and iodine was greater than knowledge regarding the recommended dose and timing of supplementation. Main healthcare providers were considered the most influential nutrition information sources. Conclusions and implications:Knowledge of and adherence to supplement recommendations for preconception and pregnancy needs improvement. While main healthcare providers may play an important role, further research is needed to explore strategies for increasing adoption of recommendations.

“…This means that up to 40% of women were still not taking recommended iodine supplements, which the authors suggested might be due to women not being informed about the need for supplementation by their antenatal care providers, despite there being written advice on supplements provided in public health facilities across NSW. More recent studies have confirmed these poor rates of supplementation, as well as finding that only 18.5% of pregnant women believed they needed a supplement [44] and only 26% of family doctors reported discussing iodine supplementation with their pregnant patients [45]. For this reason, we strongly recommend further education of antenatal clinicians regarding the importance of iodine supplementation.…”

Adequate iodine nutrition is necessary during pregnancy and breastfeeding for proper neurodevelopment in offspring. Iodine deficiency is common in developed nations and persists despite various public health interventions. This review examines the effect of mandatory iodine fortification of food on iodine status in pregnant women in Australia. Although iodine status has improved, additional supplementation is still required to achieve adequate iodine levels in pregnant and breastfeeding women.
