Chernobyl 20th Anniversary: Adequate iodine could have helped to spare many children from thyroid cancer

On the 20th anniversary of the Chernobyl nuclear plant disaster, it is important to remember that the number of children who subsequently developed thyroid cancer from radiation exposure could have been significantly lower if they had been consuming iodized salt in their daily diet at the time of the accident. Considering the increasing use of nuclear power worldwide, this is another good reason to ensure adequate iodine intake for all children ...

The re-emergence of iodine deficiency in Australia

(Mu Li and Creswell Eastman)
A national study confirms the existence of inadequate iodine intake in the Australian population, prompting calls for the urgent implementation of mandatory iodization ofall edible salt. In 1992, the Australian Centre for Control of Iodine Deficiency Disorders (ACCIDD) reported median urinary iodine (UI) levels in the Australian population were >200µg/L, consistent with iodine sufficiency. However, in recent years several studies from Victoria, New South Wales, and Tasmania have found median UI levels <100 µg/L. In surveys of pregnant women, median UIs have also been found to be well below 100 µg/L. Concerned by these data, ACCIDD conducted a national survey in 2003-2004 to document the population iodine nutritional status of schoolchildren in Australia ...

Iodine nutrition in the U.S.

(Elizabeth Pearce)
Although iodine intakes have decreased by 50% since the early 1970s, the U.S. remains iodine sufficient. Endemic goiter was eliminated in the U.S.following the initiation of salt iodization in the 1920s. The first U.S. National Health and Nutrition Examination Survey (NHANES I), conducted from 1971-1974, reported a median urinary iodine (UI) for the U.S population of 320 µg/L, reflecting adequate to excessive dietary iodine intake.By the time of NHANES III in 1988-1994, however, the median urinary iodine had fallen to 145 µg/L. The reasons for this decrease in U.S. dietary iodine intake are not clear, although some possible explanations are discussed below. Fears that this trend would continue have prompted further monitoring, but the most recent NHANES survey, conducted from 2001-2002, found that the median UI has stabilized at 168 µg/L ...

Elimination of IDD in Togo

(Théophile Ntambwe Kibambe)
Recent data suggest Togo has eliminated of IDD as a public health problem in the year 2005. A national screening in 1986 reported a goiter prevalence of 18.4% in the general population of Togo,indicating mild-to-moderate IDD nationwide. However, several regions suffered from moderate and severe goiter, especially in the Savannah regions, Plateau and Kara. The fight against IDD began with the administration of Lugol solution (potassiumiodide) to goitrous subjects in 1986-89. This was followed by distribution of Lipiodol capsules to vulnerable groups in severely endemic regionsfrom 1990-1995. In 1995, a nationwide multiple indicator study (MICSI) found only 1% of household salt was iodized ...

Progress against IDD in Belarus

(S. Sivuha and A. Lyashkevich)
The Government Program for Iodine Deficiency Prevention in Belarus was suspended in the early 1990s after the break-up of the Soviet Union. The output of iodized salt produced by Belarusian companies at that time could satisfy <14% of the country’s needs, and salt quality was generally poor. A comprehensive survey of iodine deficiency was conducted in 1997-1999 including twelve thousand children and adolescents with the support of WHO ...
