全民食盐加碘后甲状腺疾病谱的变化

碘是人体合成甲状腺激素所必需的微量元素,它的缺乏或不足会导致甲状腺功能低下,造成智能和体能发育障碍。为了解决碘缺乏病的公共卫生问题,我国实行了全民食盐加碘,现今又引发了长期食用碘盐安全性的争议。目前普遍认同碘摄入过量会导致甲状腺疾病增加,甲状腺疾病谱发生变化。盲目补碘和过度补碘都是错误的,希望随着国内外对甲状腺疾病与碘盐确切关系研究的日渐深入,不断完善食盐加碘的策略。

Changes of Thyroid Disease Spectrum after Universal Salt Iodization

Iodine is the human body essential trace element which can synthesize thyroid hormone,its lack or deficiency can lead to thyroid low function and cause intelligent and physical developmental disorders.In order to solve the public health problem——iodine deficiency disorder,China has carried out the universal salt iodization which has sparked a controversy of the security of long-term edible iodized salt nowadays.Currently,it is generally believed that excessive intake of iodine may lead to increased thyroid disease and change thyroid disease spectrum.Suppling iodine blindly and excessive iodine supplementation is wrong.Hope that,with the study on the exact relationship between thyroid disease and iodized salt at home and abroad deepened day by day,the salt iodization strategy will improves constantly.
