Although iodine prevents goiter, enlarged thyroid glands continue to be detected in subjects, especially children, in spite of adequate iodine ingestion. Iodine may cause goiter in susceptible individuals by inhibiting the organic binding of iodine as is seen in adult asthmatics, neonates born of iodine ingesting mothers and in subjects residing along the littoral of Japan. Myxedema, especially...

OBJECTIVE Mild iodine deficiency was first documented in Campania in the 1990s. We assessed the urinary iodine nutritional status of schoolchildren in Campania before the introduction of legislation for salt iodization and compared the findings with previous results to evaluate to what extent "silent" iodine prophylaxis, which accompanies socioeconomic advances, affects iodine status. METHODS...

The thyroid gland is dependent on dietary iodine for the production of thyroid hormones, normal iodine requirement being about 150-200 microg/day. Long-term deficiency in iodine intake is associated with the development of goiter. When the prevalence of goiter in a population rises above 5-10%, the problem is considered endemic. Greece is a country with a recent history of moderate iodine defic...

Iodine is an essential component of the hormones produced by the thyroid gland. Thyroid hormones, and therefore iodine, are essential for mammalian life. Iodine deficiency is a major public health problem; globally, it is estimated that two billion individuals have an insufficient iodine intake. Although goiter is the most visible sequelae of iodine deficiency, the major impact of hypothyroidis...

To the Editor: Normal thyroid function in fetuses and breast-fed infants, which is dependent on sufficient maternal dietary intake of iodine, is crucial for normal neurocognitive development.1 Children of mothers with severe iodine deficiency may have cretinism. Iodine deficiency affects more than 2.2 billion persons (38% of the world’s population) and is the leading cause of preventable mental...

AIM Objective of this study was to investigate the effect of different levels of iodine supplementation on iodine content of eggs in laying hens. MATERIALS AND METHODS In the experiment, 135 laying hens (White Leghorn) of 55 weeks age were randomly distributed to 5 dietary treatments; each group contained 27 laying hens distributed in three replicates of 9 birds each. Diet T1 was control basa...

Pregnant women are prone to iodine deficiency due to the increased need for iodine during gestation. Progress has recently occurred in establishing serum thyroglobulin (Tg) as an iodine status biomarker, but there is no accepted reference range for iodine sufficiency during pregnancy. An observational study was conducted in 164 pregnant women. At week 16 of gestation urinary iodine concentratio...

In the April issue of The Journal of Nutrition, Andersson et al. (1) published a paper entitled “Global iodine status in 2011 and trends over the past decade,” in which they discuss the status of global daily iodine intake. In this paper, both in Table 1 and in the global map of Figure 5, Greece is incorrectly listed as a country at risk of iodine-induced hyperthyroidism (i.e., median urinary i...

The use of urinary iodine as an indicator of iodine status relies in part on the accuracy of the analytical measurement of iodine in urine. Likewise, the use of dietary iodine intake as an indicator of iodine status relies in part on the accuracy of the analytical measurement of iodine in dietary sources, including foods and dietary supplements. Similarly, the use of specific serum biomarkers o...

Original Article Aims & Objectives : To evaluate distribution of iodine through edible salts and bioavailability of iodine in sub-Himalayan Tarai region of Eastern Uttar Pradesh. Methods & Design: The study has been conducted in all 14 Community development (CD) Blocks in the studied region. To measure the iodine content of salt and water samples ,a total of 490 edible salt samples and 112 drin...
