目的 根据中华儿科杂志小于胎龄儿 (SGA)的临床分型对 43例 SGA进行临床分型并观察其智能发育情况。方法 应用 Bayley婴儿发育量表对不同临床分型的SGA婴儿的智能发育进行评价。结果 匀称型 SGA其两种临床分型方法的符合率达到72 .0 9% ,而体重、头围和身高均在该胎龄值的第 10百分位以下婴儿仅占 32 .5 6 % ,其精神发育指数 (MDI)和心理运动发育指数 (PDI)均较低。匀称型 SGA的 MDI和 PDI高于非匀称型。结论 对目前 SGA的临床分型方法尚需商榷
Objective According to the clinical classification of small gestational age children (SGA) in the China Pediatrics Journal, 43 cases of SGA were typed and the intelligence development was observed. Methods The Bayley infant development scale was used to evaluate the intelligence development of different clinical types of SGA infants. Results The symmetry SGA had a coincidence rate of 72.9% for both clinical classification methods, while the body weight, head circumference and height were only 32.56% of infants below the 10th percentile of gestational age, The mental development index (MDI) and psychological motor development index (PDI) were low. The symmetric SGA has higher MDI and PDI than the non-uniform type. Conclusions The clinical classification of SGA is still open to question
