“…A study in regional NSW found that only those women who were taking prenatal supplements containing iodine had MUICs indicating sufficiency (150 μg/L) post fortification [41]. The same result was found by a study looking at a sample of pregnant women in South Australia [42].…”

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.

“…Despite being rich in iodine, fish and seafood contributed only minimally to total iodine intake due to low reported consumption, as has been reported by other studies [23,34]. Previous studies in pregnant Australian women identified that dairy foods were a major contributor to total iodine intake (57%–62%), followed by bread and cereals (19%–21%) with minor contributions from fish and seafood (3%–8%) [14,23]. …”

“…Despite the mandatory iodine fortification policy, high-risk groups with increased requirements, including pregnant and lactating women, may still not be adequately protected [11]. Dietary studies report an increased iodine intake in pregnant women since the implementation of fortification [12,13,14]. But these studies were not conducted in nationally representative samples of the population.…”

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 representative data of repeated 24-h dietary recalls from the 2011–2012 Australian National Nutrition and Physical Activity Survey, dietary iodine intakes and food group contributions were compared by age, socioeconomic status (SES), and geographical remoteness (N = 7735). The association between fortified bread intake and adequacy of iodine intake (meeting age and sex-specific Estimated Average Requirements) was investigated using logistic regression models in women of childbearing age 14–50 years (n = 3496) and children aged 2–18 years (n = 1772). The effect of SES on bread consumption was further investigated in a sub group of children aged 5–9 years (n = 488). Main sources of iodine intake at the time of the survey were cereal and cereal products, followed by milk products and dishes. Differences in iodine intake and dietary iodine habits according to age, SES and location were found (p < 0.001) for women of child-bearing age. Fortified bread consumption at ≥100 g/day was associated with five times greater odds of achieving an adequate iodine intake (OR 5.0, 95% CI 4.96–5.13; p < 0.001) compared to lower bread consumption in women and 12 times in children (OR 12.34, 95% CI 1.71–89.26; p < 0.001). Disparities in dietary iodine intake exist within sectors of the Australian population, even after mandatory fortification of a staple food. On-going monitoring and surveillance of iodine status is required.

“…In Australia and New Zealand, nutrition education is not required to be taught as part of midwifery degrees [11], and the nutrition education needs of midwives is under researched [12]. Furthermore, recent Australian research indicates that pregnant women have poor knowledge, at least for some areas of nutrition, and that women perceive advice provided by their healthcare providers, either written or verbal, to be insufficient [13,14]. This limits women's ability to plan an optimal diet to meet their needs during pregnancy.…”

A healthy diet during pregnancy is essential for normal growth and development of the foetus. Pregnant women may obtain nutrition information from a number of sources but evidence regarding the adequacy and extent of this information is sparse. A systematic literature review was conducted to identify sources of nutrition information accessed by pregnant women, their perceived needs for nutrition education, the perceptions of healthcare providers about nutrition education in pregnancy, and to assess the effectiveness of public health programs that aim to improve nutritional practices. The Scopus data base was searched during January, 2013 and in February 2014 to access both qualitative and quantitative studies published between 2002 and 2014 which focused on healthy pregnant women and their healthcare providers in developed countries. Articles were excluded if they focused on the needs of women with medical conditions, including obesity, gestational diabetes or malnutrition. Of 506 articles identified by the search terms, 25 articles were deemed to be eligible for inclusion. Generally, women were not receiving adequate nutrition education during pregnancy. Although healthcare practitioners perceived nutrition education to be important, barriers to providing education to clients included lack of time, lack of resources and lack of relevant training. Further well designed studies are needed to identify the most effective nutrition education strategies to improve nutrition knowledge and dietary behaviours for women during antenatal care.
