【摘要】 选择未进行人工补碘的轻病区、中等病区和非缺碘地区的８～１０岁、智商正常、无甲状腺肿儿童为研究对象，通过检测游离Ｔ４、甲状腺球蛋白、甲状腺ＴＳＨ受体抗体、谷光甘肽过氧化物酶、过氧化氢酶、超氧化物歧化酶、脂质过氧化物酶８项生化指标及精神运动机能测验，与非缺碘地区结果比较，发现中等病区有５项，轻病区只有一项与对照组存在显著差异，而精神运动机能检测显示，其结果与碘营养水平呈正相关，三组间有显著差异。认为在缺碘地区，即使是智商正常，无甲状腺肿的人也可以出现不同程度的机体抗氧化能力改变，而且存在明显的精神运动机能发育不全，提示在缺碘地区应开展全民补碘，提高人群碘营养水平。更多还原

【Abstract】 e selected 8-10 years old children as subjects who were of normal IQ and no goiter from mild(mild group),moderate iodine deficiency area(moderate group) and noniodine deficiency area(control group) where iodine intervention was not implemented.The psychomotor test and 8 biochemical detection including FT4,Tg,TSH,TRAB,GPx,CAT,SOD,LPO were conducted.Compared with control group there were statistically significant differences in 5 items of biochemical detection in moderate group and in 1 item in mild group.The result of psychomotor function test showed statistically significant difference among 3 groups,which was positively correlative with the level of iodine nutrition.We concluded that the subjects who were in normal IQ,no goiter,and lived in iodine deficiency area without iodine intervention might appear change of capacity of antioxidation to a certain extent and not full development in psychomotor function.The result suggested that iodine intervention should be carried on in all iodine deficiency area in order to raise iodinenutritional levels in populations.更多还原
