Iodine requirements in pregnancy and infancy

A WHO Technical Consultation has produced new guidelines on iodine requirements and monitoring in these vulnerable age groups. The Consultation, which met in Geneva, Switzerland in 2005, reached a general consensus on several important issues ...

Convincing food producers in Moldova to use iodized salt: a study tour in Switzerland

(Alexandra Eriksson, Arnold Timmer, Lilia Turcan)
According to WHO criteria, Moldova is currently mildly iodine deficient. The first epidemiological survey carried out in children between 1996 and 1998 found high levels of iodine deficiency, with a median urinary iodine level of 78 µg/L and goiter prevalence rates ranging from 27% in the south of the country to 41% in the central zone.The government of Moldova is committed to the World Fit for Children goal forthe sustainable elimination of IDD through USI. A national decree man-dates the iodization of all table and animal salt without including salt used for processed foods. Eventhough the governmental decree requires all table salt to be iodized, the enforcement of this regulation remains problematic ...

Assessment of iodine status using dried blood spot thyroglobulin

Dried blood spot thyroglobulin may be a valuable new indicator of iodine nutrition in children. Despite significant global progress against the iodine-deficiency disorders (IDD), one in three school-age children remain iodine-deficient. Iodine deficiency is the single most important preventable cause of mental retardation worldwide. Three measures – urinary iodine (UI), goiter rate, and serum thyrotropin (TSH) – are recommended for assessment of iodine nutrition inpopulations, but each has limitations ...

Ethiopia remains severely iodine deficient

With a population of 70 million suffering from drought, flooding and armed conflict, only 28% of Ethiopian households have access to iodized salt. One third of the population of Ethiopia survive on less than 1 USD a day. Children in particular arehighly affected by malnutrition. Forty per cent of children are severely and moderately underweight, 52 per cent are stunted and 11 per cent are wasted. Malnutrition is the underlying cause for more than 50 per cent of deaths of children underfive years of age. Currently, only 28% of households have access toiodized salt ...

2007 Unicef report suggests global progress against iodinedeficiency is slowing

In the 2007 report,“The State of theWorld’s Children 2007:Women and Children: The Double Dividend of Gender Equality”, Unicef provides current global figures on the percentage of households with access toiodized salt. As shown in the Table 1, global progress toward universal saltiodization, which was rapid during the 1990’s, has slowed over the pastdecade ...

The Kazakhastan salt iodization program: a remarkable public health success

On December 16, 2006, a front-page story in the New York Times (later reprinted in the Times of India and other major newspapers worldwide) by Donald McNeil Jr. entitled “On the Brink: In Raising the World’s I.Q., the Secret’s in the Salt” described the success of Kazakhstan’s iodized salt campaign. The story and photographs are excerpted below ...

Sentinel screening of iodine status in western Cameroonfinds excess iodine intake

(D.N. Lantum, E.L. Monyuytaa, and J.N. Bonglaisin)
Iodine deficiency in western Cameroon was first observed in1973-74. Endemic IDD was later described in this district by Lantumand collaborators in 1991. After this, universal salt iodization (USI) was introduced into Cameroon as a corrective intervention. In 2002, in astudy by the Ministry of Health, a median UI of 190 µg/L was reported. Because Bamoungoum in western Cameroon is one of the 20 Sentinel Zones for monitoring the effectiveness of the national USI program, ICCIDD carried out an impact evaluation there in 2006 ...

Two Kiwanians travel to Siberia to test the effect of iodine on animal productivity

The Republic of Tuva, population about 350,000, belongs to the Russian Federation. It lies next to Mongolia at the geographic center of Asia, and mountain ranges isolateit from the rest of Siberia. It has long been affected by severe IDD ...

New cretins discovered in southern Xinjiang, China

(Chen Zu-Pei)
Prof Chen Zu-Pei was surprised tofind several young cretins during arecent field study in July 2006 in Akesu Prefecture of Southern Xinjiang. He identified 16 cretins aged less than 15 years, with the youngest being 3 years old. Responding to his report of severe iodine deficiency in this region, the Chinese Ministry of Health immediately sent a team to confirm the findings and expand the investigation to three counties located in Akesuand Hetian Prefectures ...
