Gender based disparities in thyroid dysfunction among the elderly: elevated prevalence in women

Area of Science:

• Endocrinology
• Gerontology
• Public Health

Background:

• Thyroid dysfunction is a growing concern in aging populations.
• Understanding gender-specific risks is crucial for targeted health interventions.
• Iodine nutrition plays a key role in thyroid health.

Purpose of the Study:

• To investigate gender differences in thyroid dysfunction among the elderly.
• To assess the relationship between iodine levels and thyroid health in older adults.
• To identify specific thyroid conditions with higher prevalence in elderly women.

Main Methods:

• Cross-sectional study involving 3397 elderly individuals in China.
• Collection of urine and blood samples for analysis.
• Thyroid ultrasonography to measure thyroid volume and assess thyroid function and iodine status.

Main Results:

• Women had significantly higher prevalence of thyroid nodules, goiter, positive thyroid antibodies, and thyroid dysfunction than men.
• Increased iodine nutrition levels correlated with a higher prevalence of thyroid dysfunction in both genders.
• Elderly women faced significantly higher odds of thyroid nodules, goiter, positive thyroid antibodies, and thyroid dysfunction.

Conclusions:

• Significant sexual dimorphism exists in elderly thyroid health.
• Women consistently experience a greater risk of thyroid dysfunction, nodules, and autoimmunity.
• These gender disparities are evident irrespective of iodine nutrition levels.
