Very few studies have investigated whether spousal similarity for height is related to fertility. This study examined the relationship between mating for height and fertility after correction for spousal age, social class, education, and region.
The data used were collected as part of the British National Child Development Study and 6,535 husband-wife pairs for whom data were available on measured height, spousal age, education, social class, region, and the number of children were studied.
Fertility varied between the regions with the highest fertility in Scotland. Fertility tended to increase from more to less educated and from higher to lower social classes in both sexes. These relationships remained significant after correction for mean age. A negative association between husband's height in relation to fertility was noted as well as the negative and the quadratic term for wife's height. Both the linear as well as the quadratic effects of parental height difference were significantly related to fertility, but after removing the effects of mean age, age difference and mean height these effects disappeared. Analysis of region, mean age, social class, education, height, and differences in age, social class, education, and height together revealed that 32.4% of variation in fertility was explained but only mean age, mean social class and mean height and difference in social class remained significant.
The results did not provide any evidence that differential fertility was associated with spousal height difference after taking into account age, social class, education and region.
极少有研究调查配偶身高相似性是否与生育能力有关。本研究在对配偶年龄、社会阶层、教育程度和地区进行校正后，检验了身高择偶与生育能力之间的关系。
所用数据是作为英国国家儿童发展研究的一部分收集的，研究了6535对夫妻，这些夫妻的测量身高、配偶年龄、教育程度、社会阶层、地区和子女数量数据均可用。
不同地区的生育能力有所不同，苏格兰的生育能力最高。在两性中，生育能力往往随着教育程度从高到低以及社会阶层从高到低而增加。在校正平均年龄后，这些关系仍然显著。注意到丈夫身高与生育能力之间存在负相关，妻子身高也存在负相关和二次项。父母身高差异的线性和二次效应均与生育能力显著相关，但在去除平均年龄、年龄差异和平均身高的影响后，这些效应消失了。对地区、平均年龄、社会阶层、教育程度、身高以及年龄、社会阶层、教育程度和身高差异的综合分析表明，生育能力变异的32.4%得到了解释，但只有平均年龄、平均社会阶层和平均身高以及社会阶层差异仍然显著。
在考虑年龄、社会阶层、教育程度和地区后，结果没有提供任何证据表明生育能力差异与配偶身高差异有关。
