Four methods are recommended for assessment of iodine nutrition: urinary iodine concentration, the goitre rate, and blood concentrations of thyroid stimulating hormone and thyroglobulin. These indicators are complementary, in that urinary iodine is a sensitive indicator of recent iodine intake (days) and thyroglobulin shows an intermediate response (weeks to months), whereas changes in the goit...

The present study was undertaken to evaluate the iodine status of Nepalese school age children by measuring urinary iodine excretion (UIE). A population based cross-sectional study was conducted during November-December 2006 among 1,094 school age children. Spot urine samples were collected from all children and UIE was measured during February to March 2007 by an ammonium persulfate digestion ...

Methods: In a cross-sectional study, 150 pregnant women were selected by census method based on the inclusion criteria. The participants' status of iodine was measure...

This chapter provides an overview of the disorders caused by iodine deficiency. Extensively referenced, it includes data on dietary sources of iodine, goitrogens, the effects of iodine deficiency throughout the lifecycle, the pathophysiology of iodine deficiency, as well as strategies for control and monitoring of the iodine deficiency disorders, such as iodized salt and iodized oil. It emphasi...

OBJECTIVES To evaluate the difference of iodine nutritional status between rural and urban residents under the universal salt iodisation policy. SETTING A multistage cluster sampling technique was employed in the present cross-sectional study. In total, 3300 rural and 3300 urban households were selected where the investigation was conducted. PARTICIPANTS A total of 8553 rural and 8909 urban...

Iodine deficiency during the first two years of life may cause irreversible brain damage and mental retardation. The aim of the present study was to investigate, for the first time, the effect of iodine fortified milk on the iodine status of lactating mothers and their infants. In this multicenter randomized controlled trial, 84 lactating mother-infant pairs from health care centers were random...

OBJECTIVE To investigate iodine status and fish consumption of schoolchildren living in the Red Sea and White Nile regions of Sudan. DESIGN Cross-sectional study to determine urinary iodine concentration, visible goitre rate, iodine content of salt and fish consumption. SETTING Port Sudan (Red Sea) and Jabal Awliya (White Nile), Sudan. SUBJECTS Two hundred eighty (n 280) children aged 6-1...

BACKGROUND Monitoring iodine status during pregnancy is essential to prevent iodine-related disorders. The objectives of this study are to estimate iodine intake and excretion, to assess their association and to evaluate the compliance of the recommendations in a multicentre cohort of pregnant women. METHODS Cross-sectional data on maternal iodine nutritional status, compiled between weeks 8 ...

Background: Iodine deficiency and its related disorder such as goiter are endemic in Lorestan province. Following initiation of iodine deficiency control program in 1989, production, distribution and consumption of iodinated salt were begun. This survey was conducted in the framework of national monitoring survey in 2001 to find out the prevalence of goiter and urinary iodine level in order to ...
