小儿智力低下症严重危害小儿健康成长,并给家庭、社会带来负担,过去对此症重视不够。从1958年起,国内部分地区进行了调查,其发病率为1.03‰～3.8％。1979年在上海召开的儿童智能发育协作组会议,将智能障碍初步原因的分析,定为近期科研项目之一。现将我院1973～1979年住院的124例小儿智力低下症报告如下。 Children with mental retardation seriously endanger the healthy growth of children and bring a burden to families and society. In the past, this disease was not given enough attention. From 1958 onwards, some parts of China conducted a survey, the incidence rate of 1.03 ‰ ~ 3.8%. In 1979, the meeting of cooperative development group of children’s intelligence in Shanghai held the analysis of the initial causes of mental retardation as one of recent scientific research projects. Now in our hospital from 1973 to 1979, 124 cases of pediatric mental retardation reported below.
