Introduction: Universal dietary salt iodization (UDSI) was implemented in Niger in 1996. However, since 2000 there was a slowdown in progress against iodine deficiency. Objective: The objective was to assess iodine nutritional status of infants and their lactating mothers living in Dosso, the state capital of a severe iodine deficiency region in Niger. Methods: The study was centered on 238 ful...

source of faecal iodine is endogenous thyroid hormone, a fraction of which is excreted into the bile (Myant, 1956). Further evidence for an endogenous origin of faecal iodine is obtained from balance studies in patients with abnormal thyroid function (Harrison et al., 1965a). Patients with thyrotoxicosis excrete significantly more iodine in the faeces than normal, ranging from 21 to 72 ,tg/ day...

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 ...

Iodine is an essential element to humans and animals. It is a constituent of the thyroid hormones and its deficiency causes goitre and may increase the risk for intellectual deficiency in affected populations. Iodine deficiency disorders represent a significant public health problem in 118 countries worldwide (Vitti et al., 2001). Among them, thirty-two European countries were still affected by...

SUMMARY Different degrees of neurological and psychological problems are observed in endemic goiter inhabitants. To determine the effect of iodine deficiency on IQ, we checked the IQ and size of the thyroid of 194 students of an endemic goiter area and compared with that of 224 students of a non-endemic goiter area in Kohkiloyeh & Boyer Ahmad province. The average IQ of students in endemic goi...

Salt iodine content in Switzerland was raised from 7.5 to 15 mg per kg in 1980, and since then dietary iodine intake has been considered to be sufficient, even though a slight decrease due to imported food has recently been reported. The aim of this study was to establish normal values for thyroid volumes of school children who can be assumed to have had a sufficient iodine intake all their lif...

In past decades, researchers in various countries have studied the consequences of iodine deficiency on the mental and physical development of children and adults. Iodine deficiency proved to have disastrous consequences on cognitive and psychomotor development for a limited group (i.e., DeLong 1989). These are the so-called cretins, who make up more than 10% of the population in some areas. Th...

Iodine prophylaxis in Poland started in 1997 and is based on mandatory iodzation of household salt with 20-40 mg KI/ 1 kg, supplementation of bottle fed infants with iodized formulas with 10,0 microg KI/100 ml, and a voluntary supplementation of pregnant and breast feeding women with additional 100-150 microg of iodine/ day. Last evaluation of efficacy of the iodine prophylaxis performed in 200...

INTRODUCTION In order to address population-level mild iodine deficiency in Australia, a mandatory iodine fortification programme of salt used in bread was introduced in late 2009. METHODS A before-after study was conducted to assess changes in median urinary iodine concentration (MUIC) measurements, according to supplement use, in convenience samples of pregnant women attending a public ante...

Before 1987, iodine deficiency was not considered an issue of major importance in the countries of the Eastern Mediterranean Region (EMR). Progress began with a systematic national study of goitre and other iodine deficiency disorders (IDD) in the Islamic Republic of Iran in 1983. Following a major review of the prevalence of IDD in member states, Guidelines for national programmes for the cont...
