Stature is an important variable in several indices of nutritional status that are applicable to elderly persons. However, stature is difficult or impossible to measure in the nonambulatory elderly person, or its value may be spurious if measured in those elderly persons with excessive spinal curvature. Simple equations are presented for estimating the stature of elderly men from a recumbent measure of knee height and for elderly women from a recumbent measure of knee height and age. The 90 per cent error bounds for these equations for an individual are about plus or minus 6.0 cm. Knee height is highly correlated with stature.
身高是适用于老年人的几个营养状况指标中的一个重要变量。然而，对于不能行走的老年人来说，测量身高很困难甚至不可能，或者在脊柱过度弯曲的老年人中测量身高，其数值可能是虚假的。本文给出了简单的公式，用于根据卧位测量的膝高来估算老年男性的身高，以及根据卧位测量的膝高和年龄来估算老年女性的身高。这些公式对于个体的90%误差范围约为正负6.0厘米。膝高与身高高度相关。
