自 2 0世纪 70年代以来 ,我国各地逐步食用加碘食盐后 ,西藏地区的缺碘状况也得到了改善。地方性甲状腺肿的发病率明显减少 ,但实际情况并不完全明确。因此 ,我们于 2 0 0 0年 ,2 0 0 1年在西藏山南地区进行了甲状腺触诊 ,B型超声检查、甲状腺功能及尿中碘的测定。根据实地考察测定结果 ,明确了山南地区甲状腺疾病的发病情况及补碘现状 ,为今后的防治工作提供参考依据。 Since the 1970s, the iodine deficiency in Tibet has also been improved after the gradual consumption of iodized table salt in various parts of China. The incidence of endemic goiter decreased significantly, but the actual situation is not entirely clear. Therefore, we conducted thyroid palpation, type B ultrasound examination, thyroid function and urinary iodine determination in 2000 in Shannan, Tibet, by 2001. According to field survey results, the incidence of thyroid disease in Shannan area and the status of iodine supplementation were clarified to provide reference for future prevention and treatment work.
