众所周知，身体成分会随着年龄的增长而发生变化，但对老年人身体成分的人体测量指数变化率的正常值或这些变化的分布知之甚少。在本研究中，对 98 名老年白人男性和 122 名老年白人女性进行了为期 6 年的前瞻性随访。根据 1980 年研究开始时的年龄，将这些参与者分为 5 年组。对每个参与者计算三头肌皮褶厚度、中臂周长、中臂肌肉面积和体重除以年龄平方的单独线性回归。对于每个性别，这些指数的平均年度变化或斜率都很小。随着年龄的增长，皮下脂肪组织会减少，但压力或测量误差的影响可能会妨碍检测老年人身体成分指标的变化。
Changes in body composition are known to occur with old age, but there is limited knowledge of the normal values for rates of change in anthropometric indices of body composition or the distributions of these changes in the elderly. In the present study, 98 elderly white men and 122 elderly white women were followed prospectively for 6 years. These participants were divided into 5-year cohorts on the basis of age at the start of the study in 1980. Separate linear regressions of triceps skinfold thickness, midarm circumference, midarm muscle area, and weight divided by stature squared on age were computed for each participant. The mean annual changes or slopes for these indices were small for each sex. A loss of subcutaneous adipose tissue was indicated with age, but the effects of compression or measurement error may hamper the detection of changes in indices of body composition in the elderly.
