目的了解和比较农村非缺碘地区、供应碘盐和未防治IDD轻病区不同智商水平儿童精神运动功能状况。方法先用CRT-C2和CRT-RC2测试判定儿童智商,再用JPB和T分数检测确定各智商水平儿童精神运动功能。结果非缺碘地区、供应碘盐轻病区、未防治轻病区轻度智力落后儿童精神运动功能障碍率分别为25%、26.8%、41.2%,边缘智力儿童精神运动功能障碍率分别为7.9%、8%、9.5%,IQ≥80儿童精神运动功能正常;三地轻度智力落后儿童中的IQ50~59儿童精神运动功能障碍率显著高于IQ60~69儿童。结论轻度智力落后儿童精神运动功能明显低于比其智力水平高的儿童;未防治轻病区轻度智力落后儿童精神运动功能损伤率明显高于非缺碘地区和供应碘盐轻病区的轻度智力落后儿童。
Objective To understand and compare the psychomotor function of children with non-iodine-deficient areas, iodized salt supply and non-prevention and treatment of IDD in different intelligence levels. Methods The children’s IQ was determined by CRT-C2 and CRT-RC2 tests. The mental motor function of children with various IQ levels was determined by JPB and T-scores. Results In non-iodine-deficient areas, the mental retardation rate of mental retardation in children with mild mental retardation was 25%, 26.8% and 41.2% respectively in iodized salt-light endemic areas, and 7.9% in marginal intelligence children were 7.9 %, 8%, 9.5%, IQ≥80. The psychomotor dysfunction in IQ50 ~ 59 children with mental retardation was significantly higher than IQ60 ~ 69 children. Conclusion The psychomotor function of children with mild mental retardation is significantly lower than that of children with mental retardation. The rate of mental dysfunction in children with mild mental retardation who are not in prevention and treatment of mild mental retardation is significantly higher than that in non-iodine-deficient areas and iodized salt-light endemic areas Mild mental retardation children.
