Indian women of reproductive age groups commonly suffer from hypothyroidism which may be due to iodine or non iodine deficiency causes. This study was undertaken with a view to ascertain the leading cause of hypothyroidism in women of reproductive age group residing in the sub-Himalayan plain areas of Darjeeling district of West Bengal. Serum TSH, T4, T3 and Urinary Iodine Excretion (UIE) level...

Four experiments involving 163 pigs were conducted to determine the effects of iodine level in a corn-soybean meal diet on body weight gain, feed required per unit gain and thyroid status. Pigs fed the basal diet (.055 ppm iodine) with no supplemental iodine had lower plasma protein-bound-iodine levels, hypertrophied thyroids and trapped a greater amount of a 5 /~c dose of radioiodine (l st I) ...

Although the number of iodine-deficient countries has been reduced by almost 50 % over the last decade, it still remains a frequently misunderstood health problem. The most devastating effects of iodine deficiency occur during fetal development and childhood, periods in which sufficient iodine delivery remains critical. Besides the determination of thyroid size, the concentration of urinary iod...

Introduction: Kerman province was one of the Iran regions with endemic goiter. Following initiation of the program of iodine deficiency control in 1989, production, distribution and consumption of iodized salt were begun. This study was done in 2001, as part of the national monitoring survey, in Kerman. Method: In this study, 1200 schoolchildren, aged 7-10 years (600 boys & 600 girls), were sel...

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...

Iodine deficiency is not only a problem in developing regions; it also affects many industrialised countries. Globally, two billion individuals have an insufficient iodine intake, and approximately 50% of continental Europe remains mildly iodine deficient. Iodine intakes in other industrialised countries, including the USA and Australia, have fallen in recent years. Iodine deficiency has reappe...

Background: Iodine intake can be measured in various ways, and each method may have advantages and disadvantages. Objective: We sought to investigate the potential associations of various measures of iodine intake with thyroid volume, prevalence of thyroid nodules, and serum thyroglobulin. We also sought to identify, if possible, groups at risk of thyroid disease because of their food choices. ...

This review describes historical iodine deficiency in the UK, gives current information on dietary sources of iodine and summarises recent evidence of iodine deficiency and its association with child neurodevelopment. Iodine is required for the production of thyroid hormones that are needed for brain development, particularly during pregnancy. Iodine deficiency is a leading cause of preventable...
