Background: Goiter is thyroid enlargement, which is the most common visible symptom of iodine deficiency. Some studies have shown iodine deficiency in water, soil, and food in many places worldwide.We aimed to determine the prevalence of goiter and the association between urine iodine levels in children with severity and prevalence of goiter in mountainous villages of Kashan city (center of Ira...

the aim of this study was to evaluate total iodine, triiodothyronine (t3) and thyroxine (t4) status in the blood serum of holstein cows on six farms in central iran. total iodine, t3 and t4 concentrations were measured in 90 blood serum samples (15 per farm). mean concentrations of total iodine (38.80 ± 1.52 µg/l) and t3 (1.57 ± 0.10 nmol/l) were lower but the mean concentration of t4 (45.60 ± ...

Pregnant women and infants are exceptionally vulnerable to iodine deficiency. The aims of the present study were to estimate iodine intake, to investigate sources of iodine, to identify predictors of low or suboptimal iodine intake (defined as intakes below 100 μg/day and 150 μg/day) in a large population of pregnant Norwegian women and to evaluate iodine status in a sub-population. Iodine inta...

Norway has been considered iodine replete for decades; however, recent studies indicate reemergence of inadequate iodine status in different population groups. We assessed iodine status in pregnant women based on urinary iodine concentration (UIC), urinary iodine excretion (UIE), and iodine intake from food and supplements. In 804 pregnant women, 24-h iodine intakes from iodine-rich foods and i...

BACKGROUND In spite of the salt iodization, iodine deficiency disorders (IDD) have not been sustainably eliminated in China. There are coastal areas with low iodized salt coverage rates (iodine nutrition is inadequate) and other areas with excessive amounts of iodine in the drinking water. OBJECTIVE This study aimed to clarify the association of iodine deficiencies resulting from a low covera...

OBJECTIVE The aim of this review is to explore information available regarding iodine secretion in milk, both mothers and infants iodine nutrition during breastfeeding and to make recommendations for appropriate iodine supplementation during lactation. DESIGN MEDLINE was queried for studies between 1960 and 2007 that included lactation and breastfeeding with iodine and iodine deficiency. Stud...

BACKGROUND Dairy products account for approximately 60% of the iodine intake in the Norwegian population. The iodine concentration in cow's milk varies considerably, depending on feeding practices, season, and amount of iodine and rapeseed products in cow fodder. The variation in iodine in milk affects the risk of iodine deficiency or excess in the population. OBJECTIVE The first goal of this...

source of faecal iodine is endogenous thyroid hormone, a fraction of which is excreted into the bile (Myant, 1956). Further evidence for an endogenous origin of faecal iodine is obtained from balance studies in patients with abnormal thyroid function (Harrison et al., 1965a). Patients with thyrotoxicosis excrete significantly more iodine in the faeces than normal, ranging from 21 to 72 ,tg/ day...

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...

The relat~ion of iodine to thyroid metabolism has rcccived a large amount of study, but the supply of iodine in food materials had been given no systematic attention until taken up by Forbes.’ What influence its tot,al absence in the diet might have on the development of an animal is problematic, but there has not been a lack of opinion t!hat such an absence or low supply in the foods from cert...
