Gambian women are iodine sufficient despite low use of iodized salt

(Source: http://groundworkhealth.org/wp-content/uploads/2019/03/GNMS2018-Final-Report_190325.pdf)
A new national survey shows that women in The Gambia have optimal iodine intakes despite poor coverage with adequately iodized salt. Pregnant women are mildly iodine deficient except in households with iodized salt.

86% of the global population using iodized salt

(Progress report submitted to the 72nd World Health Assembly, 20–28 May 2019)
Progress in the elimination of iodine deficiency disorders has been tracked since the early 1990s.

Global Scorecard: 30 years of iodine status monitoring

Tracking progress through regular, nationally-representative iodine status surveys has become a cornerstone of the global effort against IDD.

Global Scorecard 2019

Based on the most recent available median urinary iodine concentration (UIC) data from 194 WHO Member States plus Liechtenstein and Palestine. Countries in which the most recent available survey is older than 15 years (i.e., conducted prior to 2004), are marked with an asterisk (*).

Monitoring optimal salt iodization levels in Latin America

(Gabriela Brenta, Lorena Montserrat Mosso Gomez, Maria del Carmen Silva Croome, Helton Estrela Ramos)
IDD elimination programs across Latin America demonstrates the effectiveness of mandatory salt iodization in eliminating IDD in SAC. It also reinforces the importance of achieving equity in high coverage with adequately iodized salt.

Thyroglobulin: a sensitive predictor of infant iodine status

(Excerpted from: Farebrother J et al. Thyroid. 2019 Feb 1;29(2):268-77.)
This study confirms that the use of Tg as a biomarker of iodine intake can be extended to 6- to 24-month-old weaning infants as the association between UIC and Tg concentration follows the same U-shaped pattern as in other population groups. However, its use as a predictor of thyroid dysfunction remains to be assessed.

Integrating salt reduction and salt iodization in Oman

(Dr. Izzeldin S. Hussein, Dr. Samia Al Ghannami)
Policies for salt iodization and the reduction of salt consumption to less than 5 g/day are compatible, cost-effective and of great benefit to public health. However, optimal impact of each requires (a) full implementation of universal salt iodization as recommended by IGN/WHO/UNICEF, particularly as more and more countries are going through nutrition transition, (b) effective implementation of salt reduction policies, including regulation of salt levels in processed foods, and (c) increasing iodine levels in salt as salt intakes decrease, based on an agreed scale.

Indigenous adults in northern Australia are mildly iodine deficient

(Excerpted from: Singh GR et al. Medical Journal of Australia. 2019 Feb;210(3):121-5.)
A cross-sectional study found that the median urinary iodine concentrations of young people in the Top End of the Northern Territory increased following the introduction of mandatory fortification of bread in Australia. However, median levels for some groups, particularly pregnant women and women of child-bearing age, remain in the mildly deficient range.
