The relations between some hereditary and environmental factors and the variation in infant birth weight were estimated by multiple linear regression analyses on a sample of 276 Scandinavian single term pregnancies. Gestational age explained 10.9%, fetal factors (maternal and paternal birth weights and fetal sex) 7.9%, maternal factors (parity, pre-pregnancy weight and height) 5.5% and external factors (adjusted weight gain and smoking) 5.8% of the variation in infant birth weight. It is concluded that maternal and paternal birth weights are rather poor predictors of infant birth weight. Together they explain only 5.6% of the variation in infant birth weight at term.
通过对276例斯堪的纳维亚单胎足月妊娠样本进行多元线性回归分析，估算了一些遗传和环境因素与婴儿出生体重差异之间的关系。孕周解释了婴儿出生体重差异的10.9%，胎儿因素（父母的出生体重和胎儿性别）解释了7.9%，母亲因素（产次、孕前体重和身高）解释了5.5%，外部因素（校正后的体重增加和吸烟）解释了5.8%。得出的结论是，父母的出生体重对婴儿出生体重的预测能力相当差。它们共同仅解释了足月时婴儿出生体重差异的5.6%。
