Iodine Intake and Excretion of the Patients with Thyroid Disease

갑상선질환 환자의 요오드섭취량과 배설량

Dietary iodine intake and urinary iodide excretion were meassured from 110 patients with various thyroid hormone diseses(hypothyroidism, hyperthyroidism, simple goiter and thyroid adenoma) and 67 normal control subjects. Iodine intake was assessed on the 24-hour recall dietary data using the compiled lists of food iodine values developed from various countries. Urinary iodide concentrations of drink water samples were measured with the iodide-selective electrode. The average iodine intake of the thyroid patients was 411$\mu\textrm{g}$, which was 87% higher(p<0.05) than that of the control subjects(220$\mu\textrm{g}$). Patients with hyperthyroidism and hypothyroidism or simple goiter excreted the most(0.6442ppm) amount of iodide respectively in the urine, with the control subject in the middle(0.5229ppm). Iodide concentrations of the drinking water samples were found to be in the range of 0.0015ppm to 0.0214ppm, which seemed to vary depending on the kind(underground water vs public water) and the location.
