Thyroid function in Japanese adults as assessed by a general health checkup system in relation with thyroid-related antibodies and other clinical parameters.

Background: A limited number of epidemiological studies have attempted to assess thyroid function in the general population of iodine-sufficient countries. The aim of the present study was to determine the underlying thyroid diseases responsible for abnormal thyroid function detected by a general health checkup system in Japan, and to characterize the lipid metabolism in subjects found to have thyroid dysfunction.

Methods: Serum thyrotropin (TSH), free thyroxine, anti-thyroglobulin antibodies (TgAb), anti-thyroid peroxidase antibodies (TPOAb), and TSH-binding inhibitor immunoglobulins (TBII) were determined in 1818 Japanese adults (804 men and 1014 women; mean age 51.

[The 28th report on survey of the adverse reaction to radiopharmaceuticals (the 31st survey in 2005)].
