We studied the thyroid dysfunction occurrence in the adult people who went through health examinations in Kutchan Kosei General Hospital between April 2, 2007 and March 31, 2008.Enrolled in this study were 1,647 adult men and 1,104 adult women. However, 17 men and 51 women were excluded from the study because they had histories of thyroid diseases.Serum FT3 and FT4 values were lower in women than in men. Likewise, serum TSH values for women were higher than those for men.Hypothyroidism (low serum FT3 and FT4 levels) occurred more frequently in women than in men. More women than men showed serum TSH values over 49.1μU/ml.
