Age-related statural loss has been recorded but incompletely assessed in modern populations. In this study, data collected on stature during annual bone mineral assessments are analyzed for 1,024 Caucasian individuals from southern Arizona. Continued stabilization in reported maximum heights is seen in this population. With advancing age there is a gradual decrease in height apparently beginning in the mid-40s. Thereafter, there is a relatively rapid decrease in measured height. This contrasts to the much slower rates predicted from earlier populations (Trotter and Gleser: American Journal of Physical Anthropology 9:311-324, 1951). The rate of stature loss is associated with diminution of bone mineral density as well as with maximum height. Since there are suggestions of a secular trend toward greater reductions in bone mineral density, this study suggests there may be a secular trend toward an increase in statural loss with age.
与年龄相关的身高降低在现代人群中已有记录，但评估并不完整。在本研究中，对来自亚利桑那州南部的1024名白种人的年度骨矿物质评估期间收集的身高数据进行了分析。该人群报告的最高身高持续稳定。随着年龄增长，身高明显从40多岁开始逐渐下降。此后，测量身高相对快速下降。这与早期人群预测的慢得多的下降速度形成对比（特罗特和格莱泽：《美国体质人类学杂志》9：311 - 324，1951）。身高降低的速率与骨矿物质密度的降低以及最高身高相关。由于有迹象表明骨矿物质密度有更大程度降低的长期趋势，本研究表明可能存在随着年龄增长身高降低增加的长期趋势。
