OBJECTIVE To determine the prevalence of iodine deficiency in primary school children in an Australian urban population. DESIGN AND SETTING A cross-sectional survey of school children aged 5-13 years attending a public school on the Central Coast of New South Wales in November 2000. PARTICIPANTS 324 (70%) of the 465 children enrolled in the school (180 boys; 144 girls). MAIN OUTCOME MEASU...

The major fallout of radionuclides from the nuclear power station accident at Chernobyl on 26 April, 1986, occurred in regions of Ukraine and Belarus that are believed to be moderately deficient in dietary iodine. On 17 November, 2000, in conjunction with the Ukraine-Belarus-USA study of developing thyroid disease in a cohort of individuals exposed as children, a workshop was held to review wha...

Iodine deficiency (ID) is associated with increased prevalence of goiter, increased risk for neurodevelopmental disorders, and is the world’s leading cause of intellectual deficits. Iodine nutritional status of a population is assessed by measurements of urinary iodine concentrations which are also used to define, indicate, survey and monitor iodine deficiency and consequently its treatment. Se...

The World Health Organization (WHO) estimates that worldwide 2 billion people, including 285 million school-age children, still have iodine deficiency despite major national and international efforts to increase iodine intake, primarily through the voluntary or mandatory iodization of salt. Iodine deficiency has substantial effects on growth and development and is the most common cause of preve...

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 Iodine deficiency is severe public health problem in Ethiopia. Although urinary iodine excretion level (UIE) is a better indicator for IDD the goitre rate is commonly used to mark the public health significance. The range of ill effect of IDD is however beyond goitre in Ethiopia. In this study the prevalence of goitre and its association with reproductive failure, and the knowledge o...

BACKGROUND Iodine deficiency is the most common cause of preventable mental impairment worldwide. It is defined by WHO as mild if the population median urinary iodine excretion is 50-99 μg/L, moderate if 20-49 μg/L, and severe if less than 20 μg/L. No contemporary data are available for the UK, which has no programme of food or salt iodination. We aimed to assess the current iodine status of th...

in the fall of 1991, the incidence of goiter was determined in i07x male and female school children in kermanshah city. the study was considered from two view points i.e., clinical examinations and measurements of levels of iodine excreted in urine, and was performed in three age groups: 7-11 years of age, 12-15 years of age and 16-18 years of age. clinical examination showed 16.5% occurrence o...

Thyroid disorders are common worldwide.1 In Africa, dietary iodine deficiency is the major determinant of thyroid pathology, resulting in a spectrum of iodine deficiency disorders, including goitres, hypothyroidism and mental retardation.2 Of these, mental retardation poses the most severe threat to socioeconomic wellbeing; thus, its prevention has been the focus of current global efforts towar...

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...
