Observational study.
To assess the relationship between individual self-reports and measurements of physical condition in early old age.
The use of self-reported questions assessing physical limitations remains questionable in large epidemiological studies. We aimed to test whether there is an accurate relationship between objective measures of physical capabilities and answers given to questions asked of general early old age populations.
20,335 subjects (45 to 69 years old) performed two gait speed tests at usual and at rapid speeds, and a hand grip strength test. They also completed an interview which included questions about general and specific limitations on their ability to walk one kilometer, climb stairs, and carry 5 kg over a distance of 10 meters. The questions were coded by the patients on a 4-point scale according to the severity of the limitation. Analyses were performed using description of distributions and related tests were carried out.
A fair association was found between individual self-reports and measurements of physical state: limitations on walking one kilometer and climbing stairs were more closely related to rapid than to usual gait speed and to carrying a 5 kg load. For general limitations, the strength of these associations was weaker than the other scores. The association between hand grip strength and the reported score for carrying a mass was better than that for gait speed tests.
Such simple self-assessment questions on physical performance might be useful tools for evaluating functional limitations across a large early old age population in epidemiological research.
观察性研究。
评估个体自我报告与老年早期身体状况测量之间的关系。
在大型流行病学研究中，使用评估身体限制的自我报告问题仍然存在疑问。我们旨在测试客观测量的身体能力与对一般老年早期人群提出的问题的答案之间是否存在准确的关系。
20335 名受试者（45 至 69 岁）以通常速度和快速速度进行了两次步态速度测试，以及一项握力测试。他们还完成了一项访谈，其中包括有关步行一公里、爬楼梯和携带 5 公斤重物 10 米距离的一般和特定能力限制的问题。患者根据限制的严重程度在 4 分制上对问题进行编码。使用分布描述和相关测试进行了分析。
个体自我报告与身体状况测量之间存在公平的关联：步行一公里和爬楼梯的限制与快速步态速度比通常步态速度更密切相关，与携带 5 公斤重物的关系也更密切。对于一般限制，这些关联的强度比其他评分弱。握力与携带重物的报告评分之间的关联优于步态速度测试。
这种简单的身体表现自我评估问题可能是在流行病学研究中评估大量老年早期人群功能限制的有用工具。
