BACKGROUND An epidemiologic survey showed in 1992 iodine deficiency and endemic goiter in schoolchildren from the Basque Country. OBJECTIVES (1) To determine the percentage of homes of schoolchildren where iodized salt (IS) is used; (2) to assess iodine nutrition status in schoolchildren and to compare the data collected to those available from previous epidemiological studies. DESIGN AND M...

OBJECTIVE To investigate the effect of selenium supplementation on the selenium status and selenoenzyme, especially the activity and mRNA expression of type 1 deiodinase (D1) in mice with excessive iodine (EI) intake and to explore the mechanism of selenium intervention on iodine-induced abnormities. METHODS Weanling female BALB/c mice were given tap water or 3 mg/L of iodine or supplemented ...

Iodine deficiency disorders (IDD) still represent a major public health problem, with almost 30% of the world population being exposed to the consequences of nutritional iodine deficiency (ID). In Italy, despite a sustained policy of iodine prophylaxis, more than 10% of people is still affected with goiter, and a presumably higher rate of subjects may suffer from minor cognitive deficits due to...

BACKGROUND The antioxidant function of iodine and iodine deficiency as a risk factor of preeclampsia have been previously reported. AIM To analyze the association between iodine deficiency, oxidative stress and antioxidant status with hypertensive disease of pregnancy (HPD). METHOD Fifty-seven pregnant women were recruited in the last trimester of pregnancy; 20 were diagnosed with hypertens...

Measurement of iodine status is one of those things that can seem simple until you get into the details. The recent paper by Andersen et al. in the British Journal of Nutrition provides some important new insights into, and an opportunity to reflect on, some fundamental considerations. Iodine is an essential nutrient through its role in thyroid hormones, and must be obtained from the diet in su...

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...

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...

OBJECTIVE The potential effects of four interventions to improve iodine intakes of six New Zealand population groups are assessed. DESIGN A model was developed to estimate iodine intake when (i) bread is manufactured with or without iodized salt, (ii) recommended foods are consumed to augment iodine intake, (iii) iodine supplementation as recommended for pregnant women is taken and (iv) the l...

BACKGROUND To measure the iodine nutritional status of island adults in Zhoushan, China. METHODS A comparison study was carried out in eight villages. These were selected from iodized salt and non-iodized salt districts of Zhoushan island by random sampling. The Mann-Whitney test was used to compare the urinary iodine concentration and dietary iodine intake between the two districts. RESULT...

BACKGROUND Insufficient iodine in children's diets is of concern because thyroid hormones are needed for normal growth and development, particularly of the brain. This study aimed to carry out a comprehensive assessment of the iodine status of New Zealand schoolchildren using a range of biochemical indices suitable for populations (i.e. urinary iodine concentration) and individuals (i.e. thyroi...
