确定六项身体性能指标的年龄和性别特定参考值，即握力、单腿站立、通常和最大步速下的步态速度和步长，并调查日本社区老年人在这些指标上的年龄和性别差异。我们对2002年至2011年间收集的六项队列研究的数据进行了汇总分析，这些研究是东京都老年学研究所-老龄化纵向跨学科研究的一部分。汇总分析包括来自4683名65岁或以上的非残疾社区居民的横断面数据（2168名男性，2515名女性；平均年龄：男性74.0岁，女性73.9岁）。男性未加权简单平均（标准差）握力、单腿站立、通常步态速度、通常步态步长、最大步态速度和最大步态步长分别为31.7 (6.7)kg、39.3 (23.0)s、1.29 (0.25)m/s、67.7 (10.0)cm、1.94 (0.38)m/s和82.3 (11.6)cm，女性分别为20.4 (5.0)kg、36.8 (23.4)s、1.25 (0.27)m/s、60.8 (10.0)cm、1.73 (0.36)m/s和69.7 (10.8)cm。随着年龄的增长，所有体能指标均呈现显著的下降趋势（趋势均P<0.001）。我们还根据五分位数构建了年龄和性别特定的评估标准。随着年龄的增长，握力的性别差异显著降低（年龄和性别交互作用P<0.001）。相比之下，除最大步长外，其他所有指标的性别差异均显著增加（相互作用均P<0.05）。我们的汇总分析得出了包括年龄和性别的参考价值和评估标准，用于非残疾、社区居住的日本老年人的主要身体表现测量。与年龄相关的身体机能下降的特征在性别之间存在差异。
To determine age- and sex-specific reference values for six physical performance measures, i.e. hand-grip strength, one-legged stance, and gait speed and step length at both usual and maximum paces, and to investigate age and sex differences in these measures among community-dwelling older Japanese adults. We conducted a pooled analysis of data from six cohort studies collected between 2002 and 2011 as part of the Tokyo Metropolitan Institute of Gerontology-Longitudinal Interdisciplinary Study on Aging. The pooled analysis included cross-sectional data from 4683 nondisabled, community-dwelling adults aged 65 years or older (2168 men, 2515 women; mean age: 74.0 years in men and 73.9 years in women). Unweighted simple mean (standard deviation) hand-grip strength, one-legged stance, usual gait speed, usual gait step length, maximum gait speed, and maximum gait step length were 31.7 (6.7) kg, 39.3 (23.0) s, 1.29 (0.25) m/s, 67.7 (10.0) cm, 1.94 (0.38) m/s, and 82.3 (11.6) cm, respectively, in men and 20.4 (5.0) kg, 36.8 (23.4) s, 1.25 (0.27) m/s, 60.8 (10.0) cm, 1.73 (0.36) m/s, and 69.7 (10.8) cm, respectively, in women. All physical performance measures showed significant decreasing trends with advancing age in both sexes (all P<0.001 for trend). We also constructed age- and sex-specific appraisal standards according to quintiles. With increasing age, the sex difference in hand-grip strength decreased significantly (P<0.001 for age and sex interaction). In contrast, sex differences significantly increased in all other measures (all P<0.05 for interactions) except step length at maximum pace. Our pooled analysis yielded inclusive age- and sex-specific reference values and appraisal standards for major physical performance measures in nondisabled, community-dwelling, older Japanese adults. The characteristics of age-related decline in physical performance measures differed between sexes.
