人体甲状腺功能与其自身的碘营养状况有密切关系.甲状腺分泌甲状腺激素,其分泌量增加或减少均可导致甲状腺功能失调,出现甲状腺疾病.甲状腺功能血清学指标TT3、TT4、FT3、FT4、TSH能综合反映人体的甲状腺功能状况.研究表明:1)海口市被调查居民甲状腺功能正常者居多,在甲状腺功能异常者中,甲亢人数多于甲减人数.2)女性比男性更容易患甲亢.3)36-45岁年龄组中甲亢和甲减人数均较多.4)海口地区的碘营养水平为轻度缺碘.
Human thyroid function is closely related to the nutritional status of iodine. The thyroid disease will appear if the thyriod functions is out of balance due to thyroxine increases or reduction, which is secreted by thyriod. Serology indicators T3, T4, FT3, FT4, TSH of thyroid function can comprehensively reflect the status of the body's thyroid function. The major research conclusion can be described as follows: 1) In the residents who were surveyed in Haikou, most people have the normal thyroid function, and in the thyroid function abnormalities, the number of hyperthyroidism is more than the number of hypothyroidism. 2) Women are more likely susceptible to hyperthyroidism than men. 3) Both the number of hyperthyroidism and hypothyroidism have larger proportion in 36--45 age-groups. 4)In Haikou, the iodine nutritional status is mild iodine deficiency.
