DEVELOPMENT & EVALUATION OF PHYSICAL FUNCTION MEASURES

功能的流行病学，特别是在老年人中， 最古老的老人在很大程度上是未经研究的，特别是与 老年人的代表性样本。 NHANES III调查 它致力于对老年人进行抽样调查， 这是一个独特的学习机会。 物理 功能可以通过多种方式进行测量：从自我报告 观察实际日常活动的功能。 以允许 老年人群功能的有效测量， 各种技术的可靠性，通过扩展连续体， 对观察到的身体表现进行筛选功能测试 需要建立。 该提案将制定扩大这一范围的文书， 人口研究的方便样本的老年人生活在 在农村和城市地区的社区，并做一年的后续行动， 最后一个 样本的重点是那些65岁及以上的人 并且还将包括许多75岁以上的受试者。 将确定这些措施的统计特性， 将功能与各种护理结果相关的假设将 评估。

The epidemiology of function, especially among the elderly and the oldest old is largely unstudied, particularly with representative samples of the elderly. The NHANES III survey with its commitment to sampling the elderly and to following the cohort, represents a unique opportunity for study. Physical function can be measured in a variety of ways: from self-report to observe functioning of actual daily activities. To permit efficient measurement of function in the elderly population, reliability of various techniques by expanding the continuum from a screening functional test to observed physical performance needs to be established. This proposal will develop instruments expanding this range for population studies in convenient samples of elderly living in the community in rural and urban areas and to do a one-year followup of the group. The emphasis of the sample is on those 65 and older and will also include a number of subjects over 75 years of age. The statistical properties of such measures will be established and hypotheses relating function to various care outcomes will be evaluated.
