地方性甲状腺肿是一种分布很广的世界性疾病。它不仅给患者的健康和心理状态带来一定的损害,严重时还影响生产、生活以及后代的健康。据世界卫生组织1960年调查,当时全世界地方性甲状腺肿患者约有两亿,十四年后,泛美卫生组织调查结果表明,患者还不少于两亿。因此对它的控制与预防仍是一项十分重要的工作。研究甲状腺肿流行的原因,对其流行的控制有着十分重要的意义。大量资料表明,环境因素与甲状腺肿的流行有着直接或间接的联系,故探索二者之间的关系已成了当前世界上许多学者,其中包括环境医学工作者的重要课题。地方性甲状腺肿的主要病因是由于碘摄入
Endemic goiter is a widely distributed worldwide disease. It not only brings certain damage to the health and psychological status of patients, but also affects the health of production, life and future generations in severe cases. According to a survey conducted by the World Health Organization in 1960, there were about 200 million endemic goiter patients in the world at that time. After fourteen years, the Pan-American Health Organization survey shows that there are not fewer than 200 million patients. Therefore, its control and prevention is still a very important task. The reason for studying the prevalence of goiter is of great importance to its popular control. A large number of data show that the environmental factors have a direct or indirect relationship with the prevalence of goiter. Therefore, exploring the relationship between them has become an important issue for many scholars in the world, including environmental medical workers. The main cause of endemic goiter is due to iodine intake
