This study aimed to elucidate how excessive iodine in drinking water affects iodine nutrition and thyroid function in the elderly population.

We identified a total of 385 patients with thyroid dysfunction and 385 propensity score-matched controls with euthyroid. Water, urinary, and blood samples were collected to detect the concentrations of iodine in water and urine, as well as thyroid hormones. The median (IQR) iodine concentrations in cooking water and drinking water for the total population were 294.99 (48.99, 478.14) µg/L and 172.87 (20.87, 462.13) µg/L, respectively. Among the elderly, median (IQR) urinary iodine concentration (UIC) was 394.20 (169.47, 764.41) µg/L, and 24-h urinary iodine concentration (24-h UIE) was 523.04 (277.84, 910.76) µg/day.
