Iodine is an essential nutrient for human growth and development. The thyroid gland is dependent upon iodine for production of thyroid hormone. It is a common perception that iodine deficiency is not a major public health concern in mainland Australia, with sporadic studies carried out about a decade ago showing average urinary iodine excretion levels of around 200 microg/day. Recent evidence, ...

BACKGROUND Widespread subclinical iodine insufficiency has recently been reported in Europe, based on urinary iodine using World Health Organization/Food and Agriculture Organization criteria, in particular among young women. Although urinary iodine concentration (UIC) is a useful measurement of the iodine status in a population, it does not provide an insight into the habitual iodine intake of...

Iodine is a key component of the thyroid hormones which are crucial for brain development. Adequate intake of iodine in pregnancy is important as in utero deficiency may have lifelong consequences for the offspring. Data on the iodine status of UK pregnant women are sparse, and there are no such data for pregnant women in the South East of the UK. A total of 100 pregnant women were recruited to...

BACKGROUND Infants are very sensitive to iodine deficiency. Breastfed infants are dependent on maternal iodine intake. The aim of this study was to evaluate the relationship between maternal iodine status during lactation and infant weight and length. METHODS A cross-sectional survey was conducted to investigate maternal iodine status and infant anthropometric measures in Henan Province, Chin...

After the intravenous administration of Il'1labeled L-diiodotyrosine (DIT), an increasing fraction of the labeled iodine of the serum becomes inorganic iodide as the DIT undergoes deiodination. Most of the labeled iodine which appears in the urine is inorganic iodide (1). If one makes an estimate of the renal clearance of inorganic iodide, based on the concentrations of labeled inorganic iodide...

The study was to determine the iodine status of preschool children in Rivers State, Nigeria. A cross-sectional design and an experimental were employed study. population comprised all State. multistage sampling procedure used draw a sample size 330 children. Early morning casual urine samples collected from pupils for analysis urinary concentration (UIC) using sensitive colorimetric method Sand...

To decrease total body iodine is a key point in preparation for radioiodine study and therapy. We introduced a stringent self-managed low iodine diet (LID) and compared the outcome to that of the conventional restricted iodine diet (RID) for outpatients. We measured urine iodine to creatinine ratios (I/Cr) in patients prepared with RID for one week, LID for one week, or LID for two weeks. Mean ...

Iodine deficiency is the most common preventable cause of brain damage with more than 2 billion people from 130 countries at risk. The global problem of iodine deficiency has been redefined by a readily transmitted population concept, with an easy acronym - the concept of the iodine deficiency disorders (IDD) - referring to all the effects of iodine deficiency in a population, that can be total...

Determination of iodine in biological material presents technical problems because of the large amounts of organic material present and because the concentration of iodine is often low. Many workers have used a chloric acid-digestion procedure (1), but this is tedious, and Richmond (2) found it less satisfactory for accurate measurement of fecal iodine than for determining iodine in serum or ur...
