采用学龄前韦氏儿童智力量表对武汉市某区幼儿园１２８名学龄前儿童进行智力测验，并对个人及家庭情况进行调查。结果显示：儿童智商与年龄、父母文化程度、职业、被动吸烟、经济收入有关。总智商与儿童性别无关。经多元逐步回归分析，父亲文化程度、被动吸烟与儿童智力有明显相关。提示：提高全民文化、经济水平、控制儿童被动吸烟，对儿童智力开发起着重要作用。 The preschool Webster Intelligence Scale was used to conduct intelligence tests on 128 preschool children in a kindergarten in a certain district in Wuhan. The personal and family circumstances were investigated. The results showed that children’s IQ was related to age, parental education level, occupation, passive smoking, and economic income. Total IQ has nothing to do with children’s gender. After multiple stepwise regression analysis, father’s educational level, passive smoking and children’s intelligence are obviously related. Hint: Improving the culture and economy of all the people and controlling children’s passive smoking play an important role in children’s intellectual development.
