A secular trend in body height has been experienced in many nations and populations, hypothesized to be the result of better living conditions. Educational level has been shown to be closely associated with body height. This study examined the changes in body height and popliteal height in a group of adult Chilean male workers by age cohort and the relationship of these with educational level. The body heights and popliteal heights of 1404 male workers from the Valparaíso and Metropolitan regions of Chile were measured in 2016. The sample was grouped by level of education (primary, secondary, technical and university) and age (21–30, 31–40 and 41–50 years). Robust ANOVA and post-hoc analyses using a one-step modified M-estimation of location were conducted based on bootstrap resampling. Both body height and popliteal height increased from the older to the younger age cohort. The largest increase was from the 41–50 to the 21–30 group, with a 1.1% increase in body height and 1.7% increase in popliteal height. When educational level was introduced into the analysis there was a marked increase in both body height and popliteal height for each cohort, but only in primary- and secondary-educated workers. Despite showing an overall increase in body height and popliteal height, younger workers with the highest levels of education showed fewer differences between them than did older workers with less education. The differences were larger in the older than in the younger cohorts. Similarly, this trend was less clear in workers with higher levels of education (technical and university), probably because of a dilution effect caused by increased access to higher education by workers in the lower income quintiles.

智利男性工人的文化程度及其与身高和腘窝高度的关系

许多国家和人群都经历了身高的长期趋势,假设是更好的生活条件的结果。教育水平已被证明与身高密切相关。本研究按年龄组检查了一组成年智利男性工人的身高和腘窝高度的变化,以及这些变化与教育水平的关系。2016 年测量了来自智利瓦尔帕莱索和大都会地区的 1404 名男性工人的身高和腘窝高度。样本按教育水平(小学、中学、技术和大学)和年龄(21-30、31-40和 41-50 岁)。基于 bootstrap 重采样,使用一步修改的 M 估计位置进行稳健的 ANOVA 和事后分析。身高和腘窝高度都从年龄较大的年龄组增加到年轻组。最大的增加是从 41-50 到 21-30 组,身高增加了 1.1%,腘窝高度增加了 1.7%。当将教育水平引入分析时,每个队列的身高和腘窝高度均显着增加,但仅限于受过小学和中学教育的工人。尽管显示出身高和腘高度的整体增加,但受教育程度最高的年轻工人与受教育程度较低的年长工人相比,他们之间的差异较小。老年人群的差异大于年轻群体。同样,这种趋势在受过高等教育(技术和大学)的工人中不太明显,
