INTRODUCTION Consumption of low iodine salt can cause different types of disorders associated with iodine deficiency. This study aims to determine iodine content in table salt consumed in Lubumbashi and iodine status of pregnant women who are the main target of iodine deficiency. METHODS aAdescriptive cross-sectional study was devoted to an iodometric iodine analysis of 739 salt samples colle...

Excessive iodine intake can cause thyroid function disorders as can be caused by iodine deficiency. There are many people residing in areas with high iodine levels in drinking-water in China. The main aim of the present study was to map the geographical distribution of drinking-water with high iodine level in China and to determine the relationship between high iodine level in drinking-water an...

According to previous studies, Turkey has generally been accepted as a moderate endemic iodine deficient country. However, it has recently been reported that there are regions in Turkey where iodine deficiency is more severe than previously known. The current study was aimed at ascertaining the goiter prevalence by thyroid volumes, iodine status and thyroid functions in school-age children livi...

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...

Objective: A significant negative association between serum thyroxine and urine perchlorate levels had been reported from NHANES 2001-2002 by Blount et al. (2006) for women age 12-85 with low iodine nutrition expressed as urine iodine (UI) less than 100 ug/l. We have reanalyzed the data using creatinine-adjusted urine iodine (UICr) as the measure of iodine nutrition and focused on women of chil...

We describe a simplified, automated method for screening urinary iodine. Digestion with strong acid is avoided by dialyzing urine and then directly analyzing iodine in the dialysate with the ceric ion-arsenious acid system. This method is particularly useful for analyzing large numbers of samples without loss in precision. Urinary iodine excretions are reported for 1224 children 1 to 6 years of...

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...

Up to 1992, most European countries used to be moderately to severely iodine deficient. The present study aimed at evaluating possible changes in the status of iodine nutrition in 12 European countries during the past few years. Thyroid volume was measured by ultrasonography in 7599 schoolchildren aged 7-15 years in one to fifteen sites in The Netherlands. Belgium, Luxemburg, France, Germany, A...

OBJECTIVES Median urinary iodine concentration (UIC) is the recommended method to evaluate iodine status in pregnancy, but several factors may challenge the interpretation of the results. We evaluated UIC in pregnant women according to (1) sampling in the hospital versus at home, (2) time of the most recent iodine supplement intake prior to sampling, and (3) members of their household.
