1989年以来,四川省部分原非碘缺乏病区相继报告发生甲状腺肿流行,截至写稿止已有20余县报告流行。7—14岁学生肿大率22.2—78.87%,成人尿碘28.55—48.02μg/g·cr。据1982年调查资料,这些地区的水碘含量虽然都很低(<5μg/L),但病情构不成病区。从1982年至今,大多数地区的温饱已基本解决,生活水平有明显提高,但膳食构成并无明显变化,尤其是海带等含碘食品的食入量前后变化不大。经大量深入细致的调查我们发现,
Since 1989, part of the original non-iodine deficiency wards in Sichuan Province have been reported to have goiter epidemics, as of writing has been reported in more than 20 counties. 7-14 years old students swollen rate 22.2-78.87%, adult urine iodine 28.55-48.02μg / g · cr. According to the 1982 survey, although the water iodine content in these areas is very low (<5μg / L), the condition is not a disease. Since 1982, the majority of areas have basically solved the problem of food and clothing, living standards have improved significantly, but the diet did not change significantly. In particular, iodized foods such as kelp did not change much before and after their consumption. After a large number of thorough and detailed investigation, we found that,
