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...

The Philippines is one of the countries where adequate iodine status has been achieved. However, iodine deficiency still remains an important public health problem in this country. In this study, we evaluated iodine nutrition status and investigated an awareness status of iodine deficiency targeting high school students of Tuguegarao, Philippines. A total of 260 students provided samples for ur...

OBJECTIVE The objective of this study is to evaluate the link between excess iodine intake as evidenced by increased urinary iodine excretion (UIE) and autoimmune thyroiditis in children and to assess the correlation between UIE and thyroid microsomal antibody (thyroid peroxidase [TPO]) titers in children. MATERIALS AND METHODS All children with goiter between age group 6 and 12 years, were s...

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...

In 2013, the World Health Organization (WHO) called for joint surveillance of population salt and iodine intakes using urinary analysis. 24-h urine collection is considered the gold standard for salt intake assessment, but there is an emerging consensus that casual urine sampling can provide comparable information for population-level surveillance. Our review covers the use of the urinary sodiu...

OBJECTIVES The present work was undertaken to evaluate the prevalence of goiter, state of iodine nutrition of the population, distribution of iodine through edible salt, bioavailability of iodine, consumption of common goitrogenic food that generally interfere with iodine nutrition in Naugarh sub-division of Siddharthnagar district in Uttar Pradesh, India. SETTING Five areas were selected fro...

We carried out a case-control study is to investigate the relationship between iodine deficiency and stomach cancer. We compared the ratio of urinary iodine to urinary creatinine in 100 patients diagnosed with stomach cancer and 84 people in a control group. Mean urinary iodine levels were lower in the patients with stomach cancer, 61.9 microg/g creatinine, compared to 101.7 microg/g creatinine...

This study was conducted in 2006 to assess the current iodine nutriure of the population in Haryana by assessing the urinary iodine excretion levels amongst the school age children between 6-12 years. Altogether 3,019 urine samples were collected from all the 19 districts in Haryana. The urinary iodine was analyzed by using wet digestion method. Less than 1 % of children had urinary iodine excr...
