Iodine deficiency is the most common preventable cause of brain damage. WHO estimates that some 2.2 billion people are at risk from iodine deficiency in 130 countries. A programme of universal salt iodization was established in 1994 with the aim of eliminating the problem by 2000. This paper reports progress in this field, with particular reference to the primarily scientific role of the Intern...

the aim of this study was to evaluate total iodine, triiodothyronine (t3) and thyroxine (t4) status in the blood serum of holstein cows on six farms in central iran. total iodine, t3 and t4 concentrations were measured in 90 blood serum samples (15 per farm). mean concentrations of total iodine (38.80 ± 1.52 µg/l) and t3 (1.57 ± 0.10 nmol/l) were lower but the mean concentration of t4 (45.60 ± ...

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...

Maternal hypothyroidism and hypothyroxenemia due to iodine deficiency have been shown to affect development of the newborn negatively. Maternal iodine supplementation may therefore improve cognitive performance of the offspring, even in areas of mild-to-moderate iodine deficiency (ID). Several iodine supplementation studies have been performed in mildly ID pregnant women in Europe. These studie...

1201 To the Editor: One cannot deny the importance of goiter assessment in estimating the magnitude of iodine deficiency worldwide in previous decades. While a number of relatively rare pathologic disorders can result in an enlarged thyroid, when the prevalence of goiter is common in a population (.5%), this has most often been the result of inadequate iodine in the diet. A recent article and e...

BACKGROUND Evidence showed that the occurrence of iodine deficiency endemic areas has been found in every provinces of Thailand. Thus, a new pilot programme for elimination of iodine deficiency endemic areas at the community level was designed in 2008 by integrating the concept of Sufficient Economic life style with the iodine biofortification of nutrients for community consumption. METHODS A...

Iodine deficiency is considered to be one of the most common nutrition disorders in the world and the world's greatest single cause of preventable brain damage. Despite a worldwide application of successful iodine supplementation programs over the last four decades, iodine deficiency remains a major public health problem throughout the world. All European countries except Iceland have experienc...

Studies were performed to assess the role of combined selenium and iodine deficiency in the etiology of endemic myxedematous cretinism in a population in Zaire. One effect of selenium deficiency may be to lower glutathione peroxidase activity in the thyroid gland, thus allowing hydrogen peroxide produced during thyroid hormone synthesis to be cytotoxic. In selenium-and-iodine-deficient humans, ...

BACKGROUND The New Zealand population has both marginal selenium status and mild iodine deficiency. Adequate intakes of iodine and selenium are required for optimal thyroid function. OBJECTIVE The aim of the study was to determine whether low selenium and iodine status compromises thyroid function in an older New Zealand population. DESIGN We investigated the effects of selenium and iodine ...
