High Water Iodine Concentrations Are Associated With the Prevalence of Subclinical Hypothyroidism, Thyroid Nodules, and Goiter Among Pregnant Women in Shandong, China.

Background: Both iodine deficiency and iodine excess can harm the thyroid glands during pregnancy. In areas without iodine fortification, the relationship between the water iodine concentration (WIC) and thyroid disease in pregnant women requires further investigation.

Objectives: The aim of this study was to evaluate the relationship between WICs and the prevalence of thyroid disease in pregnant women residing in areas with high WICs without access to iodized salt.

[Trends of a burden on atherosclerotic cardiovascular disease and its related risk factors in China, 1990 to 2019].

To quantitatively analyze the effects of population aging and other risk factors on the burden of atherosclerosis cardiovascular disease (ASCVD) in China from 1990 to 2019. Disability adjusted life years (DALY) and age-standardized rates obtained from the Global Burden of Disease Study 2019 (GBD2019) were used to describe the temporal trend of a burden on ASCVD. And a decomposition method established by Gupta was applied to quantify the burden related to population growth, aging, age-specific prevalence, and the severity of the disease.

Thyroglobulin can be a functional biomarker of iodine deficiency, thyroid nodules, and goiter in Chinese pregnant women.

Background And Objectives: Thyroglobulin (Tg) is considered a sensitive indicator of iodine status for children and adults, but its usefulness for pregnant women is unknown. The aim of this study was attempting to explore the relationship between Tg and iodine status and the association between elevated Tg and thyroid diseases.

Methods And Study Design: A total of 2163 pregnant women were recruited in this study.

Excessive iodine intake is associated with formation of thyroid nodules in pregnant Chinese women.

In recent decades, the prevalence of thyroid nodules (TNs) has steadily increased in pregnant women. Therefore, this study aimed to investigate associations between TNs and iodine intake in pregnant women. From March 2016 to May 2017, serum and spot urine samples, as well as demographic data and medical history, were collected from 2353 pregnant women.
