Exploring how iodine nutrition affects thyroid diseases in the elderly
Study on the Relationship Between Iodine Nutrition and Thyroid Diseases in the Elderly
Tianjin Medical University · NCT05716191
This study looks at how iodine levels in food and drink affect thyroid health in older adults in China to see if too little or too much iodine is linked to thyroid problems.

What this trial studies
This observational study investigates the relationship between iodine nutrition and thyroid diseases among the elderly population in China. It involves a cross-sectional survey that collects data from adults living in areas with varying iodine levels, assessing thyroid function and iodine intake through blood tests, urinary samples, and dietary questionnaires. The study aims to clarify the prevalence of thyroid diseases in relation to iodine nutrition and to understand the impact of both iodine deficiency and excess on thyroid health. Additionally, it compares thyroid health between different age groups to provide insights into iodine's role in elderly health.
Who should consider this trial
Good fit: Ideal candidates for this study are elderly adults who have lived in the same area for at least five years and do not have specific dietary restrictions or genetic diseases.
Not a fit: Patients with family genetic diseases, special dietary habits, or those taking iodine-containing medications may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved guidelines for iodine intake in the elderly, potentially reducing the prevalence of thyroid diseases.
How similar studies have performed: While there have been studies on iodine and thyroid health, this specific approach focusing on the elderly population and varying iodine levels is relatively novel.
