Low iodine intake during pregnancy may cause thyroid dysfunction in pregnant women and their newborn. In the present study, iodine status among a nation-wide representative sample of Belgian pregnant women in the first and third trimester of pregnancy was determined, and determinants of iodine status were assessed 1 year after the introduction of bread fortified with iodised salt. The women wer...
BACKGROUND/OBJECTIVES Despite successes recorded in combating iodine deficiency, more than 2 billion people are still at risk of iodine deficiency disorders. Rural landlocked and mountainous areas of developing countries are the hardest hit, hence the need to explore and advance novel strategies such as biofortification. SUBJECTS/METHODS We evaluated adoption, purchase, and consumption of iod...
OBJECTIVE To assess iodine status and goitre prevalence in a sample of schoolchildren in Melbourne. DESIGN Cross-sectional study of urinary iodine excretion and presence of goitre in a sample of schoolchildren from Years 5-12 attending two urban schools. PARTICIPANTS 607 children aged 11-18 years consented to thyroid gland palpation and 577 provided a urine sample on the day of examination ...
Endemic iodine deficiency in sheep is a well-recognised problem but the importance of sub-clinical iodine deficiency is difficult to assess. However, since the thyroid hormones regulate a.wide variety of physiological processes (Underwood 1977), there is the potential for iodine or thyroid activity to be a limiting factor in animal Production. For example, iodine or thyroid hormone supplementat...
It has been proposed that neonatal thyroid-stimulating hormone (TSH) concentrations are a good indicator of iodine deficiency in the population. A frequency of neonatal TSH concentrations above 5 mU/L below 3% has been proposed as the threshold indicating iodine sufficiency. The objective of the present study was to evaluate feasibility and usefulness of nation-wide neonatal TSH concentration s...
The main objective of this study was to assess the iodine nutritional status among school children (6-12 yrs) of Sundarban delta in North 24-Parganas district of West Bengal in eastern India. A total of 2050 children were clinically examined for goiter and 240 urine samples were analyzed for iodine and thiocyanate respectively; iodine content in 48 water samples and 210 salt samples were also m...
BACKGROUND Many industrialized countries struggle to maintain adequate iodine intake because of changes in dietary habits and the food supply. In Switzerland, because of declining iodine intakes in children and pregnant women, the iodine concentration in table salt was increased from 15 to 20 mg/kg. OBJECTIVE We evaluated Swiss iodine nutrition after the 1999 increase in the salt iodine conce...
OBJECTIVE Although goitre and cretinism were brought under control in Kyrgyzstan during the 1960s by centrally directed iodized salt supplies, iodine-deficiency disorders (IDD) had made a comeback when the USSR broke up in 1991. Upon independence, Kyrgyzstan started developing its own salt processing industry and by 2001 the Government enacted a law on IDD elimination, mandating universal salt ...
OBJECTIVE To assess the status of iodine deficiency in Pondicherry by finding out the urinary excretion of iodine and the prevalence of goiter among school children. METHODS 315 children between the age group of 9-13 yr from 30 schools in Pondicherry were examined for the presence of goiter and their urine samples were subjected to biochemical analysis to find out the urinary iodine levels (U...
