OBJECTIVE A survey related to iodine deficiency in the Republic of Srpska was first conducted in 1999 and resulted in the adoption of regulations concerning the quality of salt for human consumption. In order to reassess iodine status, we conducted the Republic of Srpska Iodine Deficiency Survey in 2006. DESIGN The survey was conducted in a sample of 1,200 schoolchildren using parameters reco...

The iodine intake level in a population is determined in cross-sectional studies. Urinary iodine varies considerably and the reliability of studies of iodine nutrition and the number of samples needed is unsettled. We performed a longitudinal study of sixteen healthy men living in an area of mild to moderate iodine deficiency. Iodine and creatinine concentrations were measured in spot urine sam...

BACKGROUND AND OBJECTIVES Iodine nutritional status in pregnant women is important for neuronal development of the fetus, and may vary depending on the geographic area. Thyroid function and urinary iodine excretion were therefore assessed in pregnant women from three different provinces of a large Spanish autonomous community. PATIENTS AND METHODS A descriptive study was conducted in the thre...

AIMS To evaluate the variability of 24-hour urinary iodine (UI) excretion intra- and interindividually on three days of a week in healthy subjects, living in southern Brazil, and the correlation among the urinary excretion of iodine and sodium. METHODS Cross-sectional study, including 47 volunteers: 18 individuals with one, 15 individuals with two and 14 individuals with three 24-hour urine s...

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 ...

BACKGROUND For some endocrine and nutritional biomarkers, for example, cortisol and vitamin B(12), significant associations between 24-hour renal analyte excretion and the respective 24-hour urine volume (U-Vol) have been reported. Therefore, our objective was to investigate whether 24-hour U-Vol (a marker of fluid intake) is also a relevant influencing factor of absolute daily iodine excretion...

As intra-thyroidal iodine stores should be maximised before conception to facilitate the increased thyroid hormone production during pregnancy, women who are planning to become pregnant should ideally consume 150 μg iodine/d (US RDA). As few UK data exist for this population group, a cross-sectional study was carried out at the University of Surrey to assess the iodine intake and status of wome...

In 2000, India revoked the ban on production and sale of non-iodised salt. We conducted a study in the north 24 Parganas district in the state of West Bengal to assess the prevalence of goitre, status of urinary iodine excretion (UIE) level and to estimate iodine content of salts at the household level. We surveyed 363 school children aged eight to ten years selected using a multistage cluster ...

Urinary iodine excretion is a good marker of the dietary intake of iodine and is the index for evaluating the degree of iodine deficiency, correction and toxicity. Previous studies on urinary iodine excretion measured in school children in Saki showed that iodine deficiency was still endemic. The current iodine status in the area has not been evaluated, thus this study. Random urinary iodine wa...

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...
