都匀市凯酉乡原为低碘性地方性甲状腺肿和地方性克汀病(以下简称地甲肿和克汀病),严重流行区。1976年9月对该病区进行普查地甲肿患病率53.16%,克汀病患病率7.16%。1977年7月开始供应五万分之一加碘食盐。1984年,省、州主管部门组织考核验收,地甲肿患病率已由53.16%降至5.0%(国家标准8.0%),检查加碘一年后出生的3～5岁儿童25人,未发现典型克汀病患者,显示该地供应碘盐六年后已达到国家规定的基本控制地甲病指标。为了进一步肯定该乡加碘后有无克汀病发生,我们于1987年7月再次对该乡原克汀病发病率最高的凯酉、凯阳两个大队,供应碘盐一年以后(1978年7月后)出生的全部儿童进行检查。鉴于2岁以内婴幼儿智力、听力、语言等

Found that patients with typical cretinism, show that the supply of iodized salt six years after the country has reached the basic control of disease indicators. In order to further confirm the presence of cretinism in the township after iodine addition, we again investigated the two groups of Kaiyou and Kai Yang, which had the highest prevalence of cretinism in July 1987, one year after the supply of iodized salt (1978 All children born after July of this year are inspected.
