[Epidemiologic foundation for population studies of program MZ-XVII]

Area of Science:

• Endocrinology
• Epidemiology
• Public Health

Context:

• The Chernobyl accident led to widespread radioiodine contamination, necessitating studies on thyroid health.
• Understanding the epidemiology of thyroid disorders in Poland is crucial for public health.
• Dietary iodine deficiency varies across Poland, impacting thyroid function.

Purpose:

• To establish the epidemiological foundation for population studies on thyroid disorders in Poland.
• To evaluate radioiodine dose accumulation in thyroids across different Polish regions and age groups.
• To assess dietary iodine intake and identify research capabilities for population-based thyroid studies.

Summary:

• Pilot studies identified four regions for comprehensive population research, focusing on individuals exposed to radioiodine during the Chernobyl accident.
• A random sampling strategy from voting lists will select participants (children and adults) for unified medical and laboratory examinations.
• Serum thyroid hormones (TSH, T4, T3) and autoantibodies will be analyzed using standardized kits and a unified computerized data evaluation system.
• Separate investigations will examine newborns exposed to radioiodine and individuals with pre-existing thyroid conditions receiving potassium iodide prophylaxis.

Impact:

• Provides a framework for large-scale epidemiological studies on thyroid disorders in Poland.
• Informs public health strategies regarding radioiodine exposure and iodine deficiency.
• Contributes to understanding the long-term effects of radioiodine and the efficacy of potassium iodide prophylaxis.
