随机抽取了江西宜丰县μg/L地甲病和地克病高发区车上乡(地甲现患率为44.10‰,地克病现患率为 6.40‰,水碘含量为 3.1μg/L)3～7岁儿童108人和低发区的新庄乡(地甲为32.00‰,地克病为0.00‰,水碘含量为6.7μg/L)同龄者115人的智能情况,并进行了对比研究。结果表明,车上乡儿童智商(IQ)平均值为92.78±12.99,极显著地低于新庄乡儿童的IQ均值(其IQ为99.42±13.25),t=3.777,p<0.005。两地智能中下～低下者占其所在组全部儿童的百分比分别为41.67％和20.00％,亦极显著地不同(x~2=15.55,p<0.01),说明高发区缺碘对儿童智能有相当的影响。此外,还发现两地被测儿童的身高、体重及粗动作能力均低于国内外同龄者的一般水平,并就其原因进行了初步讨论。
Jiangxi Yifeng County, g / L toxoplasmosis and high incidence of gram grams of disease on the car Township (A to prevalence rate of 44.10 ‰, Dick’s prevalence was 6.40 ‰, water iodine content of 3.1μg / L) 3 ~ 108 children aged 7 years and 115 people in Xinzhuang Township (32.00 ‰ of Achilles’ heel, Dick’s disease 0.00 ‰, water iodine 6.7μg / L) in the low incidence area and compared them with each other. The results showed that the average IQ of Chenshangxiang was 92.78 ± 12.99, significantly lower than that of Xinzhuang township children (IQ = 99.42 ± 13.25), t = 3.777, p <0.005. The percentage of smart middle-lower-lower people in both regions accounted for 41.67% and 20.00% of all the children in the same group, which were also significantly different (x ~ 2 = 15.55, p <0.01) A considerable impact. In addition, the children’s height, weight and rough ability were also found to be lower than those of their peers at home and abroad. The reasons for this were also discussed.
