缺碘性疾病和有关疾病在巴西被认为是一个严重的公共卫生问题,这一点在对学校儿童所作的两次全国性地方性甲状腺肿的调查中,以及许多地区地方性克汀病、聋哑症和先天性甲状腺机能低下症增加的报告中得到证明。本世纪六十年代卫生部制订了一项食盐加碘计划;然而,它没有产生应有的结果,原因在于碘化钾仅从国外进口,盐业不定期地得到碘化钾。况且,地方病区的多数食盐是未经加工和加碘的。 Iodine-related and related diseases are considered to be a serious public health problem in Brazil, in two national endemic goiter surveys of schoolchildren and in many areas of endemic cretinism, deafness and deafness Symptoms and congenital hypothyroidism increased in the report has been proved. In the 1960s, the Ministry of Health formulated a plan for salt iodization; however, it did not produce its due results because potassium iodide was imported from abroad and the salt industry received potassium iodide from time to time. Moreover, most of the salt in endemic wards is unprocessed and iodized.
