The authors studied electrolyte loss from profuse sweating in soccer-team players and evaluated the relationship between this source of iodine loss and iodine deficiency. Thirteen male soccer-team players and 100 sedentary students from the same high school were evaluated for 8 d, during which the players were training. The authors analyzed 208 sweat samples to determine losses of iodine, sodiu...

OBJECTIVE Pregnancy is accompanied by profound alterations in thyroid economy and relative iodine deficiency. The aim of this study was to evaluate urinary iodine excretion of pregnant women in cities with adequate and more than adequate iodine intake. METHODS A cross-sectional study was performed on schoolchildren and pregnant women in four cities in the Islamic Republic of Iran. Urinary iod...

BACKGROUND Iodine intake is often measured by a surrogate measure, namely urine iodine excretion as almost all ingested iodine is excreted in the urine. However, the methods for urine collection and the reporting of the results vary. These methods, and their advantages and disadvantages, are considered in this article. SUMMARY There are two main ways in which urine can be collected for iodine...

Oral iodized oil is the major alternative to iodized salt for correcting endemic iodine deficiency. This study responds to a need for better guidelines in its use. Schoolchildren, aged 6-11 yr, from a severely iodine-deficient area of Algeria received iodized poppy seed oil (Lipiodol) in a single oral dose containing 120, 240, 480, or 960 mg iodine (groups A-D) or in an im injection of 480 mg i...

Goiter prevalence and urinary iodine excretion levels were assessed in 568 schoolchildren (317 boys and 251 girls), aged 7-11 years, living in the Malatya province, a well-known endemic goiter area in Turkey. Five hundred sixty-eight children aged 7-11 years consented to thyroid gland palpation and provided a urine sample on the day of examination in April 2004. Median urinary iodine concentrat...

OBJECTIVE To investigate the incidence of iodine deficiency (ID) and its effects on mental function in children referred to the Dr. Sami Ulus Maternity and Children's Training and Research Hospital with a prospective diagnosis of attention deficit/hyperactivity disorder (ADHD). METHODS The study was conducted on 89 children referred in the period from September 2009 to June 2010 with a diagno...

In the April issue of The Journal of Nutrition, Andersson et al. (1) published a paper entitled “Global iodine status in 2011 and trends over the past decade,” in which they discuss the status of global daily iodine intake. In this paper, both in Table 1 and in the global map of Figure 5, Greece is incorrectly listed as a country at risk of iodine-induced hyperthyroidism (i.e., median urinary i...

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 ...

BACKGROUND Most surveys that assess the iodine status of populations target school-age children, whereas others may target nonpregnant women with the assumption that the iodine status of these groups is representative of other groups in the same population. OBJECTIVE To assess whether the median urinary iodine concentration (UIC) of school-age children or nonpregnant women can be used to accu...

BACKGROUND Iodine deficiency remains a public health problem in the world. It is the leading cause of preventable mental retardation and brain damage worldwide. Though 12 million school age children are at risk of developing iodine deficiency, there is a scarcity of literature showing the magnitude of iodine deficiency in Ethiopia. Therefore, this study aimed to determine the prevalence and ass...
