Abstract

The use of body mass index (BMI) in the elderly is limited by the measurement of height which is often unreliable. Armspan approximates to height at maturity. It may, therefore, be an alternative to height in calculating BMI. We studied the relationship between height and armspan in 101 elderly men and women. A comparison of BMI by height and armspan was made. The correlation between height and armspan was 0.93. Armspan could be estimated by doubling halfspan (recumbent). The mean difference between BMI by height and armspan was 1.79 (SD 1.11) kg/M2. We concluded that armspan is a reliable and practical estimate of height in the non-ambulant elderly. There is a case for the use of armspan instead of height in the determination of BMI in the elderly.

摘要

老年人身体质量指数（BMI）的应用因身高测量往往不可靠而受到限制。臂展在成年时接近身高。因此，在计算BMI时，臂展可能是身高的替代指标。我们研究了101名老年男性和女性身高与臂展之间的关系。对根据身高和臂展计算的BMI进行了比较。身高与臂展的相关性为0.93。臂展可以通过半臂展（卧位）加倍来估算。根据身高和臂展计算的BMI的平均差异为1.79（标准差1.11）kg/m²。我们得出结论，对于不能行走的老年人，臂展是身高的可靠且实用的估算指标。在确定老年人的BMI时，有理由使用臂展而非身高。
