摘要
目的 :评价农村不同程度碘缺乏病区学龄儿童轻度智力落后及亚临床损伤流行程度。方法 :用中国联合型瑞文测检图册 (CRT- RC2 )和农村儿童智商常模 (CRT- C2 )测验判定儿童智商 ,用天津医学院精神运动成套测验 (JPB)、测听仪、拍 X线片、标准度衡器具 ,判定学龄儿童精神运动、听力障碍者和骨龄、体格发育落后者。结果 :重、中、轻病区出生儿童的人群轻度智力落后率分别为 2 .34%、 4 .5 5 %、 0 .99%,亚临床损伤率分别为 2 9.30 %、 30 .32 %、 1 7.4 3%;重、中病区儿童轻度智力落后率和亚临床损伤率较轻病区为重。结论 :居民食用的碘盐合格率低、孕妇摄碘不足 ,可能是儿童轻度智力落后及亚临床损伤的原因。
Objective:To evaluate the children's mild intelligent retarded rates and endemic subclinical cretinism in iodine deficiency disorders regions.Methods:Intelligence quotient (IQ) was measured by Raven Progressive Matrix(CRT-C 2). Psychomotor, hearing and somatic retardators were detected by Jin Yi Psychomotor Test Battery (JPB),hearing measure, X-ray and standard physical measurer.Results:The mild intelligent retarded rates were 2.34%, 4.52%, and 0.99%, respectively in the severe, the moderate and the mild regions. The subclinical injury rates were 29.30%,30.32%,17.43% respectively in the severe, the moderate and the mild regions. The intelligent retarded rates or the subclinical injury rates of the severe or moderate region were significantly higher than those of the mild region.Conclusions:Low qualified iodized salt rates at household level, especially deficient iodine intake in pregnant women, may lead to the fact that mild intelligent retarded and endemic subclinical injury children are still born in iodine deficiency disorders regions.
