Background - Iodine deficiency is known to be one of the most common, yet preventable cause of mental impairment in the world. With increasing concerns over iodine insufficiency in the UK, there is renewed interest in the status of women of childbearing age. Previously, the UK populations’ iodine intakes were believed to be replete, however, recent studies have raised concerns once more. Methods – Ten women of childbearing age completed a cross sectional survey and 3-day diet diary to identify their knowledge of iodine, intake and iodine rich foods within their diets. Results – A greater number of women studying nutrition related degrees understood the role of iodine in the body, compared with women of a non-nutrition based degree. Iodine intake of participants did not increase in relation to an increase in overall knowledge, however nutrition students did have a better knowledge score than non-nutrition students. Ninety percent of participants had iodine intake below daily recommended values. However, the mean overall iodine intake of participants studying a nutrition degree was higher than those studying a non-nutrition degree. Examination of food diaries, demonstrated that dairy products were the main contributor to iodine in the diet. Conclusion - Overall knowledge score, was negatively correlated to an increased intake of iodine, however, nutrition students mean knowledge score and iodine intake was higher and therefore suggests that the course type may have an impact on iodine intake. On the other hand, nutrition students may in fact have a greater interest and a more conscientious approach to a balanced, healthy diet and thus increased iodine intake. Additionally, in both groups the main iodine source within the participants’ diets was dairy products and in particular cows’ milk. In conclusion this research supports recent studies that the UK is iodine deficient, however presents conflicting results as to whether knowledge can have an effect on intake. Additionally, it highlights the risk of iodine deficiency and supports the idea that it is an important public health issue in the UK and that work should continue into appropriate supplementation.
