不可否认，随着年龄的增长，身体的组成会发生变化，这些变化会带来过多的生理后果，影响功能水平以及当前和随后的健康（Rosenberg，1989年; Heymsfield等人，1995年）。健康和功能是老龄化过程中相互关联的状态（Nagi，1976年），它们之间的过渡以及疾病和残疾受到老龄化过程中身体组成变化的影响。健康、患病和营养不良的老年男女身体成分变化的表现形式和一致性各不相同。这种变化影响了我们对估计、测量、指数和身体成分变化的解释，这些变化与老年人的健康和功能水平有关。当今的老年人是二十世纪健康和营养改善的首批受益者，这一事实进一步影响了这些关系。本文综述了当今老年人身体成分水平和变化与健康和功能的关系。如果身体成分在老年发生变化，这些变化是从什么水平发生的？这些变化发生的时间或年龄是什么？现有的身体成分参考数据对当今老年人的适用程度如何？
There are undeniable changes in the body's composition with old age, and these changes can bring about a plethora of physiological consequences affecting levels of function, and current and subsequent health (Rosenberg, 1989; Heymsfield et al. 1995). Health and function are interrelated states within the ageing process (Nagi, 1976), and transitions amongst them and disease and disability are affected by alterations in the body's composition through the ageing process. The expression and uniformity of changes in body composition vary among healthy, sick and malnourished elderly men and women. This variation affects our interpretation of estimates, measures, indices, and changes in body composition as related to levels of health and function in the elderly. These relationships are further affected by the fact that the elderly of today are some of the first recipients of the improvements in health and nutrition that have occurred during the twentieth century. The present paper reviews some of the issues relating levels of and changes in body composition with health and function among today's elderly. If body composition changes in old age, from what levels are the changes occurring? What is the timing or age at onset of the changes and how appropriate are existing body composition reference data for elderly people today?
