This paper focuses on the nature of the physical growth-behavioral development association in well-nourished as compared with undernourished populations. Multiple regression analyses were calculated to determine the magnitude of IQ variance accounted for by physical growth variables and socioeconomic status indicators in a group of 3- to 6-year-old children from Cambridge, Massachusetts. The prevalence of malnutrition within this sample was negligible. Weight-for-height percentile was the only physical growth measure that explained a significant portion of the IQ variance. This finding contrasts with what is found in undernourished populations where height is generally the most potent explanatory variable of mental test score variance. In undernourished populations height is a reflection of nutritional history; in well-nourished populations weight-for-height is an indicator of physiological maturation.
本文重点关注营养良好人群与营养不良人群中身体生长与行为发展之间关联的本质。对马萨诸塞州剑桥市一组3至6岁儿童进行了多元回归分析，以确定身体生长变量和社会经济地位指标所解释的智商差异程度。该样本中营养不良的发生率可忽略不计。身高体重百分位数是唯一能解释相当一部分智商差异的身体生长指标。这一发现与营养不良人群中的情况形成对比，在营养不良人群中，身高通常是心理测试分数差异的最有力解释变量。在营养不良人群中，身高反映营养史；在营养良好人群中，身高体重是生理成熟的指标。
