由于随着年龄的增长而发生的生理和认知变化，准确测量老年人的身体活动（PA）是一项独特的挑战。本研究的主要目的是系统地审查PA的措施，他们的使用和适当性与老年人。次要目的是确定老年人PA措施之间的协议水平。通过电子数据库识别文献。如果研究在老年人（> 65岁）中检查了至少2项PA测量（间接和/或直接）之间的相关性和/或一致性，则研究合格。36项研究符合合格标准。研究中PA的间接和直接测量在解决关键维度（即，频率、强度、时间、类型）。间接和直接测量之间的平均相关性为中度（r=0.38）。间接测量与其他间接测量之间的相关性较弱（r=0.29），而直接测量与其他直接测量之间的相关性较高（真实的世界：r= 0.84;控制设置：r=0.92）。协议是最强的直接PA措施与其他直接措施在真实的世界和实验室设置。虽然关于其他巴勒斯坦权力机构措施之间的平均差异的一致性有明显的趋势（即，直接与间接、间接与间接）之间的差异，只有有限数量的研究报告了可比单位。尽管缺乏一个明确的趋势之间的协议PA措施在老年人，研究结果强调了有效，准确和可靠的测量的重要性。为了推进这一领域，研究人员需要以更标准化的方式评估老年人的PA（即，结果的一致报告，对临界点和时期长度的共识，使用适当的验证工具）。在此之前，研究人员在选择适合其研究问题的PA测量方法以及比较各种研究中的PA水平时应谨慎。
Due to physiological and cognitive changes that occur with aging, accurate physical activity (PA) measurement in older adults represents a unique challenge. The primary purpose of this study was to systematically review measures of PA and their use and appropriateness with older adults. A secondary aim was to determine the level of agreement between PA measures in older adults. Literature was identified through electronic databases. Studies were eligible if they examined the correlation and/or agreement between at least 2 measures, either indirect and/or direct, of PA in older adults (> 65 years of age). Thirty-six studies met eligibility criteria. The indirect and direct measures of PA across the studies differed widely in their ability to address the key dimensions (i.e., frequency, intensity, time, type) of PA in older adults. The average correlation between indirect and direct measures was moderate (r=0.38). The correlation between indirect and other indirect measures (r=0.29) was weak, while correlations between direct measures with other direct measures were high (real world: r= 0.84; controlled settings: r=0.92). Agreement was strongest between direct PA measures with other direct measures in both real world and laboratory settings. While a clear trend regarding the agreement for mean differences between other PA measures (i.e., direct with indirect, indirect with indirect) did not emerge, there were only a limited number of studies that reported comparable units. Despite the lack of a clear trend regarding the agreement between PA measures in older adults, the findings underscore the importance of valid, accurate and reliable measurement. To advance this field, researchers will need to approach the assessment of PA in older adults in a more standardized way (i.e., consistent reporting of results, consensus over cut-points and epoch lengths, using appropriate validation tools). Until then researchers should be cautious when choosing measures for PA that are appropriate for their research questions and when comparing PA levels across various studies.
