目的：探讨母亲智商、婚姻状况、家庭收入和家庭环境质量对低出生体重儿认知发育的直接和间接影响。方法：采用分层回归对一个大型数据集进行二次分析，确定与低出生体重儿3岁时认知结果相关的因素。母亲智商是一个关键变量，因为它与儿童智商高度相关，因为母亲智商影响其他预测变量之间的关系模式，包括婚姻状况，收入水平和家庭环境对儿童智商的影响。分析表明，这些变量对儿童智商的影响与母亲的iQ.Conclusions：儿童早期干预计划应针对那些低出生体重儿的认知发育受损的风险最大。风险最大的儿童是那些与未婚、低智商母亲生活在一起的儿童。
Objective: To examine direct and mediated effects of maternal IQ, marital status, family income, and quality of the home environment on the cognitive development of low birthweight infants.Methods: Secondary analyses on a large dataset using hierarchical regression identified factors correlated with cognitive outcomes in children at 3 years of age who were born at low birthweight.Results: Maternal IQ was a critical variable, because it was highly correlated with child IQ and because maternal intelligence influenced patterns of relationships among other predictor variables including marital status, income level, and home environment on child IQ. Analyses revealed that effects of these variables on child IQ interacted with maternal IQ.Conclusions: Early childhood intervention programs should target those low birthweight infants most at risk for impaired cognitive development. Children at greatest risk are those living with unmarried, low IQ mothers.
