摘要
[目的 ]了解和比较未供应碘盐与供应碘盐 IDD轻病区同期出生儿童的智商、亚临床损伤程度及儿童人群的亚克汀病患病率。 [方法 ]采用 CRT- C2 测验判定儿童智商 ,JPB、测听仪、X射线片、身高及体重判定儿童精神运动和听力障碍、骨龄和体格发育落后情况 ,按我国卫生行业标准诊断亚克汀病。 [结果 ]未供应碘盐轻病区儿童人群智商均值为96 .8,轻度智力落后率 7.5 % ;供应碘盐轻病区为 10 0 .9、3.5 %。未供碘盐病区各智力水平儿童的精神运动和听力障碍率、骨龄和体格发育落后率均较供碘盐病区高。轻度智力落后儿童的亚临床损伤率 ,未供碘盐区为 6 0 .1% ,供碘区为4 0 .2 % ;定量计算儿童亚克汀病患病率 ,未供碘盐区为 4 .5 % ,供碘区为 1.4 %。 [结论 ]IDD轻病区供应碘盐后出生的轻度智力落后儿童亚临床损伤率及儿童人群亚克汀病患病率 ,均显著低于未供应碘盐轻病区 ,食用碘盐是预防子代亚临床损伤的有效措施。
To compare the intelligence level, degree of sub clinical impact, the rates of sub cretinism in children born in the same period between non iodine salt supplying and supplying areas To examine IQ of children by CRT C 2, determine the psychomotor retardation, bone age and physical development by JPB, audition, X ray photographs, body height and weight Sub cretinism was diagnosed by national occupational health criteria The mean IQ was 96 8 and the rate of mild mental retardation was 7 5% in children from non supplying areas and the mean IQ was 100 9 and the rate was 3 5% from iodine supplying areas The rate of mental retardation, psychomotor retardation, hearing disorder,development delay of bone age and physical health in non iodine supplying areas were higher than the supplying areas The rate of sub clinical impact was 60 1% and 40 2% respectively for the two areas The rate of sub cretinism was 4 5% and 1 4% respectively for the two areas [Conclusion] The mental retardation,the rate of sub clinical impact and sub cretinism in iodine supplying areas are lower than that in non iodine supplying areas The intake of iodine salt is an effective method for preventing sub clinical impact on children
