Iodine deficiency disorders (IDD) are related to the degree of iodine deficiency. In European countries, characterized by mild to moderate iodine deficiency, neurological deficits or minor neuropsychological impairments have been described. Urinary iodine excretion (UIE) ranged from 30 to 170 mcg/L, 141 millions of people were at risk of IDD, 97 millions were affected by goiter and 0.9 millions...
OBJECTIVES Hypothyroidism in utero leading to mental retardation is highly prevalent and recurrent in developing countries where iodine deficiency and thiocyanate overload are combined. So, to explore and identify human population's risks for developing iodine deficiency disorders and their endemicity in Western Cameroon, with the aim to prevent this deficiency and to fight again it, urinary io...
OBJECTIVE To estimate worldwide iodine nutrition and monitor country progress towards sustained elimination of iodine deficiency disorders. METHODS Cross-sectional data on urinary iodine (UI) and total goitre prevalence (TGP) in school-age children from 1993-2003 compiled in the WHO Global Database on Iodine Deficiency were analysed. The median UI was used to classify countries according to t...
Iodine, as a component of the thyroid hormones, is crucial for brain development and is therefore especially important during pregnancy when the brain is developing most rapidly. While randomised controlled trials of pregnant women in regions of severe iodine deficiency have shown that prenatal iodine deficiency causes impaired cognition, less is known of the effects in regions of mild deficien...
This editorial reviews the impact of iodine deficiency (1) on thyroid function in pregnant women and neonates and (2) on the neurointellectual development of infants and children. All degrees of iodine deficiency (mild: iodine intake of 50-99 microg/day, moderate: 20-49 microg/day, and severe: <20 microg/day) affect thyroid function of the mother and the neonate as well as the mental developmen...
BACKGROUND Pregnancy is associated with parallel increase in both iodine, and thyroid hormone requirements suggesting that, there may be the need for additional iodine intake during this period to prevent potential iodine insufficiency. Medically, an excess or reduced intake of this micronutrient has negative effects on the individual's health. This study aimed at identifying the pattern of iod...
Background & Objective: Iodine deficiency was a public health problem in Iran before iodine supplementation. In order to evaluate the iodine status of school aged children in Zanjan, this survey was conducted in the frame work of national monitoring survey in 2001 to find the prevalence of goiter and urinary iodine level. Materials & Methods: 1200 schoolchildren, aged 7-10 years, were selected ...
Objective(s): Particularly in developing countries, selenium and/or iodine deficiencies are encountered and use of pesticides in agriculture are not well-controlled. Fenvalerate is a pyrethroid insectide used in agriculture and has applications against a wide range of pests. This study was designed to evaluate the effects of fenvalerate on hepatic and cerebral xenobiotic metabolizing enzyme act...
This article reviews the available data on the study of iodine deficiency disorders in Hong Kong and to discuss the approach towards preventing such disorders in Hong Kong. The importance of iodine and iodine deficiency disorders is described, and the available data on the dietary iodine intake and urinary iodine concentration in different populations of Hong Kong are summarised and discussed. ...
