43例低出生体重儿的智能发育

MENTAL DEVELOPMENT OF 43 LOW BIRTH WEIGHT INFANTS

本文对43例无围产期合并症的低出生体重儿4～10岁时,应用韦氏儿童智力量表测定智商(IQ)。智能发育落后者占23.3％,高于一般群体。早产小样儿组智能发育落后发生率显著高于足月小样儿及早产适于胎龄儿组,出生体重<2000g者,高于>2000g者;父母文化程度高者与父母文化程度低者有显著性差异;学龄儿童智能发育落后发生率高于学龄前儿童。

Forty-three LBW infants without any complication in perinatal period were devided into three groups (full-term SGA, pre-term SGA, pre-term AGA) and were followed up at age around four to ten years.The develop- mental abilities were assessed by using WISC-R. All childien aapproach- ed normal weight, height and head circumference. The incidence of men- tal retardation (23.3%) was higher than that of general human group.Pre- mature SGA group had significantly lower average IQ and higher mental retardation than the other two groups. Also the incidence of mental re- tardation at birth-weight <2000g was higher than that of ≥ 2000g. There was a remarkable. high incidence of mental retardation in school child that preschool child. Mental development was obviously related to the educational factor of their parents.
