Methods A cross-sectional survey was conducted in the general population aged 15-69 years. A questionnaire regarding general and personal characteristics and relevant information was administered. Ultrasonography of the thyroid was performed, and serum triiodothyronine（T3）, tetraiodothyronine（T4）, serum thyroid stimulating hormone（TSH）, free triiodothyronine（FT3）, free tetraiodothyronine（FT4）, thyroglobulin antibody（Tg Ab）, thyroid peroxidase antibody（TPOAb）, and TSH receptor antibody（TRAb） levels were measured for each individual subject. Results The prevalence rates of TNs in the whole population, females and males were 27.76%, 34.04%, and 21.60%, respectively. The prevalence of multiple nodules increased with age, whereas the prevalence peaks differed between males and females. The median UICs in the whole population and females with non-TNs were higher than those of subjects with TNs（P=0.0035, P=0.0068）. The median UICs in subjects with a single TN were higher than those in subjects with multiple TNs（P=0.0164, P=0.0127）. The result showed a U-shaped curve relationship between UIC and prevalence of TNs. The prevalence of TNs was the lowest when the UIC was 140-400 μg/L. Conclusion The prevalence of TNs was nearly 30% and increased with age. The relationship between UIC and prevalence of TNs is U-shaped, with an increase in risk when the UIC was 〈140 μg/L and 〉400 μg/L. Very low or high UIC levels need attention and correction.展开更多
