Background: Iodine is required throughout pregnancy for thyroid hormone production, which is essential for fetal brain development. Studies of iodine status in pregnant women from the United Kingdom (UK) have focused on early gestation (,16 wk). Data on the effect of advancing gestation on urinary iodine excretion are conflicting, with suggestions of both an increase and a

OBJECTIVE To assess iodine nutrition and thyroid function in Mexican childbearing age women. METHODS 101 childbearing age women (21.7 ± 3.5 years) randomly selected from the university student population participated in this cross-sectional study. TSH, thyroid hormones, anti-thyroid antibodies, thyroid volume, iodine intake, and urinary iodine concentration (UIC) were assessed. The knowledge ...

BACKGROUND Iodine is an essential micronutrient for normal human growth and development. It is estimated that more than 1.6 billion people live in iodine-deficient environments, yet there are still some countries and areas where the prevalence of iodine-deficiency disorders is unknown. OBJECTIVE To establish the prevalence of iodine-deficiency disorders in the Zanzibar Islands, a community as...

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...

BACKGROUND Urinary iodine is a good biochemical marker for control of iodine deficiency disorders. Our aim was to develop and validate a simple, rapid, and quantitative method based on the Sandell-Kolthoff reaction, incorporating both the reaction and the digestion process into a microplate format. METHODS Using a specially designed sealing cassette to prevent loss of vapor and cross-contamin...

␮g/L). We also analyzed an aliquot of each of the three samples for 13 consecutive days (a total of 39 samples); 38 of the 39 (97.5%) were placed correctly, and the 39th was placed in the category immediately above the correct category. We diluted a urine sample containing 6.3 ␮mol/L mmol/L added to a sample containing 1.15 ␮mol/L (146 ␮g/L) iodine did not change the iodine concentration measur...

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...

INTRODUCTION Iodine deficiency disorder (IDD) is one of the preventable major public health problems in India. It has been always thought that goitre was only found in the Himalayan goitre belt. Recent surveys outside the conventional goitre belt have identified foci of iodine deficiency in other parts of India. AIM 1) To assess the prevalence of goitre among school-going children in the age ...

OBJECTIVES We estimated iodine status of Korean population by determining the concentration of spot urinary iodine (UI) with a reliable method based on the Sandell-Kolthoff reaction. MATERIALS AND METHODS A total of 540 urine samples from apparently healthy subjects were collected, and UI, urinary sodium (UNa), and urinary creatinine (UCr) were determined from those samples and analyzed with ...
