OBJECTIVE Mild iodine deficiency was first documented in Campania in the 1990s. We assessed the urinary iodine nutritional status of schoolchildren in Campania before the introduction of legislation for salt iodization and compared the findings with previous results to evaluate to what extent "silent" iodine prophylaxis, which accompanies socioeconomic advances, affects iodine status. METHODS...

BACKGROUND Iodine content in table salt was adjusted from 30-50 mg/kg to 21-39 mg/kg from March of 2012 in Henan Province, China. The vulnerable population may be at risk of iodine deficiency. OBJECTIVES To determine whether the iodine intake was sufficient in vulnerable populations and to investigate what factors may be associated with iodine status in these vulnerable populations in Henan P...

The use of urinary iodine as an indicator of iodine status relies in part on the accuracy of the analytical measurement of iodine in urine. Likewise, the use of dietary iodine intake as an indicator of iodine status relies in part on the accuracy of the analytical measurement of iodine in dietary sources, including foods and dietary supplements. Similarly, the use of specific serum biomarkers o...

As intra-thyroidal iodine stores should be maximised before conception to facilitate the increased thyroid hormone production during pregnancy, women who are planning to become pregnant should ideally consume 150 μg iodine/d (US RDA). As few UK data exist for this population group, a cross-sectional study was carried out at the University of Surrey to assess the iodine intake and status of wome...

21 Iodine is a key component of the thyroid hormones which are crucial for brain development. 22 Pregnant women are vulnerable to iodine deficiency because their requirement for iodine is 23 higher than that of non-pregnant adults. Data on the iodine status of UK pregnant women are 24 sparse and there are no such data in the South East. One hundred pregnant women were recruited 25 to a cross-se...

BACKGROUND Dietary iodine intake is required for the production of thyroid hormone. Consequences of iodine deficiency include goiter, intellectual impairments, growth retardation, neonatal hypothyroidism, and increased pregnancy loss and infant mortality. SUMMARY In 1990, the United Nations World Summit for Children established the goal of eliminating iodine deficiency worldwide. Considerable...

OBJECTIVE To review methods for evaluating iodine deficiency in pregnant women and young infants and to discuss factors to be considered in the interpretation of their results. DESIGN Review of the literature regarding the various methods available for assessing iodine status. SETTING Population surveys and research studies. SUBJECTS Pregnant women and young infants. RESULTS Several fac...

21 As intra-thyroidal iodine stores should be maximised before conception to facilitate the increased 22 thyroid-hormone production of pregnancy, women who may become pregnant should ideally consume 23 150 µg iodine/day [US Recommended Dietary Allowance (RDA)]. As few UK data exist in this 24 population group, our aim was to assess iodine intake and status in women of childbearing age in a 25 c...

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 ± ...

Iodine deficiency re-emerged in New Zealand in the 1990s, prompting the mandatory fortification of bread with iodised salt from 2009. This study aimed to determine the iodine status of New Zealand children when the fortification of bread was well established. A cross-sectional survey of children aged 8-10 years was conducted in the cities of Auckland and Christchurch, New Zealand, from March to...
