WHO Director-General Dr. Tedros Adhanom Ghebreyesus has praised The Lancet's GBD study as a great example of collaboration to improve people's health and lives. The Lancet argues that health is created from a broader prospectus that includes the quality of education, economic growth, gender equality, and migration policy. And the document also emphasizes the continuing importance of child and maternal malnutrition. We at IGN believe that ensuring optimal iodine nutrition is essential to progress.
