“…The SAC's awareness of legislation concerning iodine deficiency documented in this report has not changed when compared to the previous survey, undergone in 2012 (42.5% versus 45%) [21]. In our survey, awareness of the legislation to deal with iodine deficiency was associated with a greater propensity to use iodized salt, thus confirming the importance and efficacy of educational intervention in schools and other institutions to improve iodine status in the population [9].…”

“…In European countries, data on the association between socioeconomic status, education, and iodine supply are more conflicting [15,16]. Moreover, as regards nationality, in a previous report by our group, on data collected between 2015 and 2016, we reported a higher receptiveness of foreign-origin SAC towards the educational intervention, when compared to Italian-origin SACs [9]. Preliminary data from the Italian National Observatory for Monitoring Iodine Prophylaxis (OSNAMI) for the years 2015-2019, on a sample of 2523 SAC (11-13 years old) residing in 7 Italian regions (Liguria, Toscana, Emilia Romagna, Marche, Umbria, Lazio, Sicilia), indicated that the UIC was now sufficient (118 ug/L), and iodized salt was used in 75% of Italian school canteens.…”

“…Between-run inaccuracy was assessed by repeatedly measuring two levels of in-house quality control material (95 and 300 μg/L), and was from 1.7% to 2.8%. At the start of each run, a standard curve was also recorded with serial dilutions of a synthetic tester [9].…”

“…Physicians from our Endocrinology Unit provide training for the medical staff at the Food Hygiene and Nutrition Services (SIAN) with the aid of several computer-based materials provided by the MIUR illustrating the main concepts behind iodine prophylaxis and the importance of a responsible use of salt. Then the SIAN staff train the schoolteachers at the designated schools, and the teachers in turn conduct educational sessions with their students, using targeted oral presentations, based on a multistep program already used in a previous survey [9].…”

Background: Fifteen years after a nationwide voluntary iodine prophylaxis program was introduced, the aims of the present study were: (a) to obtain an up-to-date assessment of dietary iodine intake in the Veneto region, Italy; and (b) to assess dietary and socioeconomic factors that might influence iodine status. Methods: Urinary iodine concentration (UIC) was obtained in 747 school students (median age 13 years; range: 11–16 years). Results: The median UIC was 111 μg/L, with 56% of samples ≥ 100 μg/L, but 26% were < 50 μg/L, more frequently females. Iodized salt was used by 82% of the students. The median UIC was higher among users of iodized salt than among non-users, 117.0 ug/L versus 90 ug/L (p = 0.01). The median UIC was higher in regular consumers of cow’s milk than in occasional consumers, 132.0 μg/L versus 96.0 μg/L (p < 0.01). A regular intake of milk and/or the use of iodized salt sufficed to reach an adequate median UIC, although satisfying only with the combined use. A trend towards higher UIC values emerged in regular consumers of cheese and yogurt. Conclusion: Iodine status has improved (median UIC 111.0 μg/L), but it is still not adequate as 26% had a UIC < 50 μg/L in the resident population of the Veneto region. A more widespread use of iodized salt but also milk and milk product consumption may have been one of the key factors in achieving this partial improvement.

“…The importance of this issue arises from the fact that it affects the health of the mother and child and increases the financial burden related to this condition worldwide [28]. With effective interventions such as iodinating the dietary salt, educating pregnant women and proper coordination between medical and health departments, this problem can be prevented [29,30]. Defining the causative chain of iodine deficiency during pregnancy and factors affecting it are necessary in order to prevent maternal iodine deficiency.…”

Background: Mild to moderate iodine deficiency in pregnant women may expose them to the increased risk of the development of goiter and thyroid disorder. There is a relationship between low maternal UIC (Urinary iodine concentration) in pregnancy and diminished placental weight and neonatal head circumference. The current study was an attempt to assess iodine nutritional status, its determinants and relationship with maternal and neonatal outcomes. Methods: In this population based cross-sectional study, which was conducted from April 2017 to September 2018, information was collected from 884 women of 20-45 years old who referred for periodic pregnancy visits. UIC was measured in random urine samples by applying a manual method which was based on the Sandell-Kolthoff technique. Information related to neonatal and maternal complications was collected from the individuals enrolled in the study through systematic follow-ups of the research team in each hospitals and the referral of trained midwives to the place of delivery and the retrieval of the case files.

Purpose Sodium is essential to life. However, its dietary excess is detrimental to the cardiovascular system, and sodium restriction is a crucial step in cardiovascular prevention. Iodine deficiency has been fought worldwide for decades, and substantial success has been achieved introducing the use of iodine-enriched salt. Nevertheless, areas of iodine deficiency persist around the world, both in developing and industrialized countries, and a major concern affecting dietary sodium reduction programs is represented by a possible iodine intake deficiency. There are substantial differences in the source of alimentary iodine among countries, such as iodized salt added, household tap water, seafood, or salt employed in packaged food. It is clear that a sodium-restricted diet can induce differences in terms of iodine intake, depending on the country considered. Moreover, iodine status has undergone relevant changes in many countries in the last years. Methods Systematic review of literature evidence about the possible effects of sodium restriction on population iodine status. Results To date, the available results are conflicting, depending on country, salt iodization policy, as well as time frame of data collection. However, to ensure an optimal iodine supply by salt fortification, without exceeding the current recommendation by World Health Organization for salt intake, seems to be an achievable goal. Conclusion A balanced approach may be obtained by an adequate iodine concentration in fortified salt and by promoting the availability of iodized salt for household consumption and food industry use. In this scenario, updated prospective studies are strongly needed.
