【摘要】 目的探讨精神发育迟滞患儿的智力障碍程度及其相关因素。方法在对185例参加计划生育精神医学鉴定的精神发育迟滞患儿开展临床调查的基础上,以智商为因变量,以年龄、热性惊厥史、窒息史、胎次、生产过程、孕期用药史、CT检查结果、脑电图检查结果、中枢神经系统疾病史为自变量进行多元逐步回归分析,探讨各因素对精神发育迟滞患儿智商的影响。结果185例精神发育迟滞患儿中,轻度精神发育迟滞49例,中度120例,重度16例。韦氏儿童智力量表(C-WISC)测评显示患儿智商为28～69,平均(47.6±11.6)。对智商影响有意义的因素依次为脑电图检查结果、中枢神经系统疾病史及窒息史。结论脑电图检查结果、中枢神经系统疾病及窒息史与儿童智商相关,必须重视孕期、围生期保健及避免中枢神经系统疾病的发生。更多还原

【Abstract】 Objective To investigate the dysnoesia in mental retardation(MR) children and its related factors.Methods A multiple stepwise regression analysis was performed on IQ (dependent variable),and on age,history of febrile convulsion and asphyxia,parity,production precess,history of drug use during pregnancy,CT and EEG findings,central nervous system disease history(independent variable),to explore the impacts of various factors on IQ in 185 MR children.Results Mild MR was found in 49,moderate in 120 and severe in 16.Wechsler intelligence scale for Children(C-WISC) showed that the IQ of these children were 28～69,averaging (47.6±11.6).The factors having meaningful impact on IQ were EEG findings,the history of central nervous system disease and asphyxia.Conclusion EEG findings,history of central nervous system diseases and asphyxia are associated with children′s IQ.Attention must be paid to health care during pregnancy and perinatal period to avoid central nervous system diseases.更多还原
