我省属沿海地区,过去一直认为海盐充足,海产品丰富,未见有关地方性克汀病(简称克汀病)及地方性甲状腺肿(简称地甲病)的报导。1977年对粤北山区的乐昌县大源乡三个村的普查,结果地甲病患病率50. 5%,克汀病患病率1. 16%,环境明显缺碘(水碘0. 78ug/l)。碘缺乏病(iodinc deficiency disorders IDD)可造成不同程度的脑发育落后,已被国内外许多学者所承认和证实,食用碘盐是防治 IDD 的有效方法。我省对碘盐防治地甲病的效果,特别是对儿童智力,体格发育的影响,未有系统的观察和报道。我们于1987年6月对 My province is a coastal area, the past has always believed that sea salt sufficient, rich seafood, no local cretinism (referred to as cretinism) and endemic goiter (referred to as toremia) reported. In 1977, a survey of three villages in Dayuan Township of Lechang County in mountainous areas of northern Guangdong resulted in a prevalence of 50.5% of cases of a disease, a prevalence of 1.16% of cretinism, and an apparent iodine deficiency (water iodine 0 78ug / l). Iodine deficiency disorders (IDDs) can cause varying degrees of brain development and fallback. They have been acknowledged and confirmed by many scholars both at home and abroad. Eating iodized salt is an effective way to prevent and treat IDD. In our province, the effect of iodized salt prevention and treatment on amebiasis in our province is not systematically observed or reported, especially on the mental and physical development of children. We did it in June 1987
