足月窒息儿早期干预全国性协作研究,至1994年10月满1.5～2岁共102例,窒息儿随机分为干预组34例,常规育儿组30例,正常对照组38例。三组在性别、母亲文化、环境条件及体格发育方面无明显差别。1.5岁智能测查结果显示,窒息干预组精神发育指数(MDI)比常规育儿组平均高14.6分,(P值<0.0001)。窒息干预组MDI、PDI达正常对照组水平(P>0.05),而窒息常规育儿组MDI比正常对照组低9.7分(P<0.01),其中智力低下者2例(6.7％),干预组中无1例智力低下。
There were 102 cases aged from 1.5 to 2 years old as of October 1994 and 34 cases of asphyxia were randomly divided into intervention group (n = 30), conventional parenting group (n = 30) and normal control group (n = 38). There was no significant difference between the three groups in terms of gender, mother’s culture, environmental conditions and physical development. The results of 1.5-year-old intelligent test showed that the index of mental development (MDI) in asphyxiated group was 14.6 higher than the average parental group (P <0.0001). MDI and PDI in the asphyxia group were higher than those in the normal control group (P> 0.05), while those in the asphyxiated group were 9.7 (P <0.01) lower than those in the normal control group, with 2 cases (6.7% No case of mental retardation.
