BACKGROUND Iodine intake is often measured by a surrogate measure, namely urine iodine excretion as almost all ingested iodine is excreted in the urine. However, the methods for urine collection and the reporting of the results vary. These methods, and their advantages and disadvantages, are considered in this article. SUMMARY There are two main ways in which urine can be collected for iodine...

Goiter prevalence and urinary iodine excretion levels were assessed in 568 schoolchildren (317 boys and 251 girls), aged 7-11 years, living in the Malatya province, a well-known endemic goiter area in Turkey. Five hundred sixty-eight children aged 7-11 years consented to thyroid gland palpation and provided a urine sample on the day of examination in April 2004. Median urinary iodine concentrat...

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...

OBJECTIVE To assess iodine status and goitre prevalence in a sample of schoolchildren in Melbourne. DESIGN Cross-sectional study of urinary iodine excretion and presence of goitre in a sample of schoolchildren from Years 5-12 attending two urban schools. PARTICIPANTS 607 children aged 11-18 years consented to thyroid gland palpation and 577 provided a urine sample on the day of examination ...

Sufficient data relating urinary iodine excretion in children to other iodine deficiency indicators are lacking in Egypt. We assayed urinary iodine concentration and serum levels of thyroid stimulating hormone (TSH), thyroglobulin, free triiodothyronine (T3) and free tetraiodothyronine in 99 school-aged Egyptian children. Goitre was found in 25 children. Median urinary iodine concentration was ...

  Iodine deficiency remains a major health problem in the world, including some parts of Iran. It has been recognized that there is usually a close and inverse relationship between iodine in the soil and water and presence of endemic goiter. Calcium has been suggested as one of goitrogens, though the definite role, extent and mechanism particularly in human have not been studied. Serum protein-...

In order to assess the Japanese dietary iodine intake, we examined the urinary iodine excretion of those on an ordinary Japanese diet chosen at random and observed whether the thyroid function might affect the amounts of urinary iodine excretion. The subjects consisted of cases of untreated hypothyroidism and chronic thyroiditis (CT) and euthyroid controls who were healthy people or had non-thy...

21 Iodine is a key component of the thyroid hormones which are crucial for brain development. 22 Pregnant women are vulnerable to iodine deficiency because their requirement for iodine is 23 higher than that of non-pregnant adults. Data on the iodine status of UK pregnant women are 24 sparse and there are no such data in the South East. One hundred pregnant women were recruited 25 to a cross-se...

BACKGROUND AND OBJECTIVE: Congenital hypothyroidism due to iodine deficiency is the most common cause of preventable mental retardation in the world. The lowest level of iodine deficiency during pregnancy could result in disorders such as miscarriage, premature delivery, intrauterine fetal death, low birth IQ, mental retardation, hearing difficulty and speech impediments. This study aimed to ev...

The association between iodine deficiency and poor mental and psychomotor development is known. However, most studies were undertaken in areas of very low iodine intake. We investigated whether a similar association is found in schoolchildren from southern Europe with a median urinary iodine output of 90 microg/liter. Urinary iodine levels were measured in 1221 children who also completed a que...
