We studied sixty-three children of severe motor and intellectual disabilities syndrome aged between 3 and 5 years, who live in Okinawa. Severe motor and intellectual disabilities syndrome were defined as those who belong to classes 1 approximately 4 of Ohshima's classification (incapable of walking with IQs not more than 35). The prevalence rate was about 1.12/1,000 live births. Forty-four% of the total children belonged to class 1 of Ohshima's classification (bedridden and IQs less than 20). The factors were: congenital 31.7%, perinatal 38.1%, postnatal 14.3%, and unknown 15.9%. The perinatal factor was still relatively high as compared with the others.
我们研究了63名年龄在3至5岁之间、居住在冲绳的患有严重运动和智力残疾综合征的儿童。严重运动和智力残疾综合征被定义为属于大岛分类中1至4级的儿童（无法行走且智商不超过35）。患病率约为每1000例活产中有1.12例。在所有儿童中，44%属于大岛分类的1级（卧床不起且智商低于20）。病因如下：先天性因素占31.7%，围产期因素占38.1%，产后因素占14.3%，不明因素占15.9%。与其他因素相比，围产期因素仍然相对较高。
