目的 :了解婴儿早期发育状况 ,早期发现异常。方法 :采用“0— 6岁儿童智力发育筛查测验”(DST)对486名出生 3— 6月婴儿进行测试。结果 :婴儿发育异常检出率 1 0 3% ,可疑异常检出率 10 49% ;不同出生体重婴儿发育水平有差异 ,低出生体重与正常出生体重婴儿比较 ,发育商 (DQ)和智力指数 (MI)均低。结论 :对婴儿进行早期发育筛查能及时发现发育偏离 ;动态观察发育异常和可疑小儿 ,早期诊断 ,及时采取针对性的干预极为重要 ;同时也提示低出生体重是影响小儿发育的重要原因。 Objective: To understand the early development of infants, early detection of abnormalities. METHODS: A total of 486 infants from 3-6 months of age were tested using the Childhood Developmental Intelligence Screening Test (DST). Results: The detection rate of infants’ developmental abnormalities was 103% and the detection rate of suspicious abnormalities was 10 49%. The developmental levels of infants born at different birth weights were different. The birth weight (DQ) and intelligence index MI) are low. Conclusion: Early developmental screening of infants can detect developmental deviations in time. Dynamic observation of dysplasia and suspicious infants is very important in early diagnosis and timely intervention. It also suggests that low birth weight is an important factor affecting the development of infants.
