早产、窒息和低出生体重对小儿智能发育影响的研究

Study of relationship between children's mental development and their history of preterm, asphyxia and LBW.

采用ＤＤＳＴ、Ｇｅｓｃ１１ 两种智测方法对头位经产道分娩的１１６ 名０３ 岁小儿进行了回顾性研究。结果：（１）ＤＤＳＴ法的结果４ 组间具有差异（ Ｐ＜０－０５）；进一步检验发现早产组与对照组的智能发育差异无显著性（Ｐ＞０－０５），而窒息组、低体重组与对照组的差异有显著性（０－０１ ＜ Ｐ＜０－０５）；（２）Ｇｅｓｅｌｌ 测试４ 组内小儿的智能发育呈显著差异（Ｐ＜ ０－０５） ；而早产组、窒息组及低体重组与对照组进一步分析得Ｐ值依次小于０－０５、０－０１ 和０－０１；（３）各病例组内的统计学处理发现：早产、窒息和体重的程度不同，其对小儿的智能发育的影响亦不同（Ｐ值分别为０－０１ ＜ Ｐ＜ ０－０５ 和Ｐ＜０－０１）。结论：早产、窒息及低体重仅在一定条件下才能起消极作用。

This present paper aims at determinming the possible action of preterm, asphyxia and LBW(low birth weight) to mental development by means of both DDST(Denver Development Screening Test) and Gesell Intellingence Test.116 vaginally born children with head presentation were divided into four groups at random:(1)preterm group(n-32);(2)asphyxia grou(n=25);(3)LBW group(n=29);(4)control group (n=30).The results showed that the three case groups, thether by DDST or Gesell method, were significantly rearded compared with the control group(pvalue less than 0.05).However through further investigation, the author found that not all of the children were developmentally retarded. The research suggested that only on cretain circumstances did the above three factors influence negatively upon the children's mental reported before. And this needs further study to confirm.
