Endemic goitre--iodine deficiency disorders.

Area of Science:

• Endocrinology
• Public Health
• Nutritional Science

Background:

• Endemic goitre, defined as thyroid enlargement in over 10% of a population, is primarily caused by iodine deficiency.
• Iodine deficiency disorders (IDD) encompass a range of health problems including goitre, cretinism, hypothyroidism, and impaired mental and physical development.
• Globally, over 800 million people are at risk of IDD, with over 190 million affected, including millions with cretinism and developmental defects.

Purpose of the Study:

• To highlight the global health impact of iodine deficiency disorders (IDD).
• To emphasize the effectiveness of iodine supplementation as a preventive measure.
• To discuss challenges in the implementation of IDD prevention programs.

Main Methods:

• Review of epidemiological data on the prevalence of goitre and IDD.
• Assessment of the public health consequences of iodine deficiency.
• Analysis of strategies for iodine supplementation and their implementation challenges.

Main Results:

• Iodine deficiency is the leading cause of endemic goitre and associated developmental disorders worldwide.
• Iodine deficiency disorders (IDD) affect hundreds of millions globally, causing significant morbidity and developmental impairments.
• Iodine supplementation, particularly through iodized salt, is a highly effective and feasible method for IDD elimination.

Conclusions:

• Iodine deficiency disorders (IDD) represent a major global public health challenge that is preventable.
• Effective prevention and elimination of IDD are achievable through widespread iodine supplementation programs.
• Overcoming logistical and political hurdles is crucial for the successful implementation of IDD prevention strategies worldwide.
