Bodenhorn等人(2017)引发了相当大的争议,他们认为,在工业化期间,美国和英国的军事样本中观察到的成人身材下降是对样本中不可观察物的选择的虚构。虽然随后的论文对这种偏见的程度提出了质疑(Komlos和A 'Hearn 2019; Zimran 2019),但人们对历史人体测量数据集中的选择偏见再次感到担忧。因此,本文将Bodenhorn等人关于不可观察的选择偏差的讨论扩展到儿童成长的来源,特别关注可能扭曲成长年龄模式的偏差。了解儿童生长模式的变化是非常重要的,因为这些变化是成人身高长期增长的基础,并与今天在发展中国家观察到的儿童发育迟缓有关。然而,在包含儿童和青少年身高和体重的历史数据集中,有重要的未观察到的选择来源。这篇文章特别强调了偏见的三个常见来源:(1)19世纪末和20世纪初对儿童进入中学的积极选择;(2)入伍年龄门槛造成的年龄轮廓扭曲了身高;(3)改变制度生态,决定儿童被送到哪些机构。对这些偏见的解释从两个方面调整了文献:19世纪青春期发育突增的证据比以前承认的要弱;一些关于儿童成长变化的长期分析过于偏颇,无法提供信息,尤其是对日本。
Bodenhorn et al. (2017) have sparked considerable controversy by arguing that the fall in adult stature observed in military samples in the United States and Britain during industrialization was a figment of selection on unobservables in the samples. While subsequent papers have questioned the extent of the bias (Komlos and A’Hearn 2019; Zimran 2019), there is renewed concern about selection bias in historical anthropometric datasets. Therefore, this article extends Bodenhorn et al.’s discussion of selection bias on unobservables to sources of children’s growth, specifically focusing on biases that could distort the age pattern of growth. Understanding how the growth pattern of children has changed is important because these changes underpinned the secular increase in adult stature and are related to child stunting observed in developing countries today. However, there are significant sources of unobserved selection in historical datasets containing children’s and adolescents’ height and weight. This article highlights, among others, three common sources of bias: (1) positive selection of children into secondary school in the late nineteenth and early twentieth centuries; (2) distorted height by age profiles created by age thresholds for enlistment in the military; and (3) changing institutional ecology that determines to which institutions children are sent. Accounting for these biases adjusts the literature in two ways: evidence of a strong pubertal growth spurt in the nineteenth century is weaker than formerly acknowledged and some long-run analyses of changes in children’s growth are too biased to be informative, especially for Japan.
