Assessment of the association of ​​high-iodine​​ exposure in drinking water, iodine intake, and thyroid function in 3-14-year-old children.

ABSTRACT: Drinking water with a high iodine content is one of the sources of iodine intake, And excessive iodine intake can affect thyroid function. This study aims to investigate the effects of long-term exposure to iodine-rich groundwater on iodine intake And thyroid function in children. We recruited a total of 3,216 children aged 3-14 years on multiple occasions from 2013 to 2023 from counties with high groundwater iodine concentrations in Shandong Province, China. We collected drinking water samples to measure water iodine concentration (WIC), spot urine samples And 24-hour (24-h) urine samples to examine the iodine status. We measured the thyroid volume and collected fasting blood and dried blood spot samples to examine the thyroid function. The median WIC of children's drinking water was 183
