【摘要】 在采用碘盐防治措施的碘缺乏病区,对397名6岁以下儿童作DDST测定,结果表明:DDST结果正常者占85.1％,异常和可疑者占7.8％,不合作者占7.1％。对DDST结果异常和可疑的31名儿童进一步作Gese11测定,智力发育商低于正常者29名,占93.4％,DDST假阳性比例占6.6％,说明DDST信度较强。DDST与Gese11智力发育测定法两者的测试能区相近,结合使用,可以很快在婴幼儿群体中对智力发育落后者做出定性定量诊断,建议在碘缺乏病防治研究中推广这一方法。更多还原

【Abstract】 We used DDST to test children in IDD area where iodinated salt has already applied. The results show : (1)Normal children of DDST results are 85. 1% ,abnormal and undecided are 7. 8%,the non-cooperative are 7. 1%. (2)Using Gesell to further test 31 children whose DDST results are abnormal and undecided,29(93. 4%) children’s Development Quotient are lower than normal;the falsely positive rate of DDST results is 6. 6%. This proved high reliability of DDST. (3)The testing zones of DDST are close to Gesell. If using these two methods in combination, we can make a rapid diagnosis of intelletual retardation in quantity and quality in colony of children easily. So we suggest to popularize these methods in IDD control and research.更多还原
