OBJECTIVE To study the effect of salt reduction on iodine status and to determine whether iodine consumption was still adequate after salt reduction in a population where universal salt iodisation is mandatory. DESIGN A substudy of a cluster randomised controlled trial, with schools randomly assigned to either the intervention or the control group. SETTING 28 primary schools in Changzhi, no...

PURPOSE Even mild iodine deficiency may negatively affect cognitive performance, especially at a young age. Our aim was to investigate iodine status in very young children and to assess the importance of iodized salt in processed foods of which the use has decreased during the last years in Germany. METHODS Twenty-four hours urinary iodine excretion (UIE) as a marker of iodine intake was meas...

Thyroid cancer (TC) is the most common endocrine malignancy and in most countries, incidence rates are increasing. Although differences in population iodine intake are a determinant of benign thyroid disorders, the role of iodine intake in TC remains uncertain. We review the evidence linking iodine intake and TC from animal studies, ecological studies of iodine intake and differentiated and und...

BACKGROUND A common recommendation for the treatment of hypertension is dietary salt intake restriction. However, dietary salt is one of the major sources of iodine. This study evaluated the association between dietary salt restriction and iodine deficiency among adults in the United States. METHODS Multiple regression models, which controlled for confounders, were used to evaluate the associ...

Iodine deficiency early in life impairs cognition and growth, but iodine status is also a key determinant of thyroid disorders in adults. Severe iodine deficiency causes goitre and hypothyroidism because, despite an increase in thyroid activity to maximise iodine uptake and recycling in this setting, iodine concentrations are still too low to enable production of thyroid hormone. In mild-to-mod...

BACKGROUND Iron and iodine deficiencies affect more than 30% of the world's population. Typical Indian diets contain adequate amounts of iron, but the bioavailability is poor. This serious limiting factor is caused by low intake of meat products rich in heme iron and intake of phytates in staple foods in the Indian diet, which inhibits iron absorption. OBJECTIVE To test the stability of doubl...

Iodine is required for the production of thyroid hormones, which are essential for normal brain development, and the fetus, newborn, and young child are particularly vulnerable to iodine deficiency. The iodine requirement increases during pregnancy and recommended intakes are in the range of 220-250 microg/day. Monitoring iodine status during pregnancy is a challenge. New recommendations from W...

This review discusses the current status and challenges in development of novel iodine capture adsorbents, focusing on adsorption mechanisms evaluation methods.

BACKGROUND Iodine deficiency has been identified as a significant public health problem in Iran. The main strategy for controlling iodine deficiency was nationwide salt iodination. Over 10 years after starting this program, goiter is still endemic in school children. Iron deficiency may have interfered with the iodine intervention program. The objective of the present study was to evaluate the ...

BACKGROUND Iodine deficiency in infancy can impair neurocognitive development, but there are few available indicators of iodine intake during this critical period. In many countries, access to newborns in maternity clinics in the first few days after birth is high. If spot urine samples could be collected, reference data for urinary iodine concentration (UIC) would be useful to evaluate their i...
