为了正确说明各可能的危险因素与儿童智力低下之间的关系,控制混杂因素的干扰,并对危险因素的定量测定值进行分析,我们用logistic回归模型对影响儿童智力低下的因素进行了多变量分析。对象和方法253名4～7岁儿童来自上海市五个区的托幼机构及散居儿童,由上海市第六人民医院发育诊断室按韦克斯勒氏学龄前儿童智能量表(WPPSI)测定智商,同时按统一调查表格进行影响智力发育因素的调查。对每一对象了解的内容,包括居住地区、母亲怀孕情况(有无孕前高血压、孕七月高血压浮肿)、儿
In order to correctly explain the relationship between possible risk factors and mental retardation in children, to control the interference of confounding factors and to analyze the quantitative determination of risk factors, we used multivariate logistic regression model to analyze the factors influencing children’s mental retardation analysis. Subjects and Methods 253 children aged 4 to 7 years old were from kindergartens and diasporas in Shanghai’s five districts and were assessed by Wechsler’s Preschool Children’s Intelligence Scale (WPPSI) by Shanghai Sixth People’s Hospital Developmental Diagnostic Laboratory IQ, at the same time according to the unified survey form to investigate the impact of mental development factors. For each object to understand the content, including the area of residence, the mother’s pregnancy (with or without pre-pregnancy high blood pressure, pregnancy-induced hypertension in edema), children
