Thanks to the cooperation and tremendous efforts from those involved in the Ethiopian salt industry, and support from MI and its partners, salt processors in the country have made great progress in increasing the supply of adequately iodized salt in the country.

MI is taking advantage of this time-sensitive opportunity to examine the impact of switching from non-iodized to iodized salt on infant and child mental development.

We know that iodine deficiency causes mental impairment in children and that when iodine status is improved, so is mental development.

We are hoping to learn the extent to which mental development can be modified in children when they switch from consuming non-iodized salt to consuming iodized salt, which to date has not been directly estimated.

This study will provide a strong contribution to the overall evidence base for the positive impact of salt iodization, vital for advocacy messages to donors and policy makers.
