Background:

  • Iodine deficiency during pregnancy and infancy leads to severe health issues.
  • While progress has been made in the Western Hemisphere, iodine deficiency persists in some areas.
  • Fragile monitoring systems threaten the sustainability of iodine deficiency control efforts.

Purpose of the Study:

  • To recommend strategies for addressing persistent iodine deficiency.
  • To evaluate the safety and efficacy of iodine supplementation.
  • To emphasize the importance of monitoring iodine status.

Main Methods:

  • Review of existing literature on iodine deficiency and supplementation.
