Iodised salt programs and iodine status in the Eastern Mediterranean

What it found

Adding iodine to salt has greatly improved iodine levels across the Eastern Mediterranean region.

Several countries have now nearly wiped out disorders caused by too little iodine.

What they found

Studies in people

More salt has iodine

Countries in the Eastern Mediterranean have made strong progress in adding enough iodine to the salt people eat.

Fewer iodine disorders

Several nations in the region, including Qatar, Kuwait, Bahrain, Jordan, Oman and Iran, have either eliminated or nearly eliminated health problems linked to low iodine.

Other findings

Tracking iodine levels

Careful monitoring helps governments measure how big the iodine problem is and see if adding iodine to salt is working for the population.

What the authors conclude

  • They advise governments to take active steps to make iodised salt rules mandatory through teamwork across different sectors.
  • They say countries need to carefully check their populations' iodine nutrition levels.
  • They recommend that national programs for adding iodine to salt and for cutting down salt intake must work together.

How it was done

The World Health Organization asked all nations to add iodine to salt starting in 1991 because low iodine is a leading preventable cause of brain damage. The authors wanted to check how well countries in this region were doing at fixing that problem.

They looked at national reports on iodine levels in school children aged 6 to 12 years from countries in the Eastern Mediterranean. These reports are gathered every 3 years to track progress over time.

What it can’t tell you

  • We summarised it from the abstract only.
  • This is a review of regional progress rather than a controlled trial. It cannot prove that iodised salt alone caused the improvements seen in each country.
