BACKGROUND With population aging, a key question is whether new cohorts of older people are in better health than previous ones. This study aimed to compare the physical and cognitive performance of community-dwelling older adults assessed at similar age in 2005, 2010, and 2015. METHODS This repeated cross-sectional analysis used data from the Lausanne cohort 65+, a three random sample population-based study. Performance of participants aged 66-71 years in 2005 (N=1309), 2010 (N=1253) and 2015 (N=1328) was compared using a battery of six physical and four cognitive tests. Analyses included tests for trend across samples and multivariable linear regression models. RESULTS Adjusted performance in all four timed physical tests (gait speed, Timed Up-and-Go, five times chair stand, and Moberg Picking-Up) improved across samples from 2005 to 2015, by +12.7% (95% CI +10.5%; +14.9%) to +20.4% (95% CI +17.7%; +23.0%) in females, and by +10.6% (95% CI +8.7%; +12.4%) to +16.7% (95% CI +13.4%; +20.0%) in males. In contrast, grip strength and balance did not improve across samples. Adjusted cognitive performance showed no change in the Trail Making Test, but worsened significantly across samples for the Mini-Mental State Examination, verbal fluency, and the clock drawing test in both females (1.9% (95% CI 2.7%; 1.1%) to 6.7% (95% CI 8.9%; 4.6%)) and males (2.5% (95% CI 3.4%; 1.6%) to 8.0% (95% CI 11.1%; 4.9%)). CONCLUSIONS Over the last decade, performance of adults aged 66-71 years improved significantly in timed physical tests but worsened in most cognitive measures among later-born samples.

瑞士社区老年人的身体和认知表现趋势。

背景技术随着人口老龄化,一个关键的问题是新的老年人群是否比以前的人群更健康。这项研究旨在比较在2005、2010和2015年以相似年龄进行评估的社区居住老年人的身体和认知表现。方法这项重复的横断面分析使用了洛桑队列65+(三个随机样本人群)基础研究。使用一系列六项物理测试和四项认知测试,比较了2005年(N = 1309),2010(N = 1253)和2015(N = 1328)66-71岁的参与者的表现。分析包括样本间趋势的检验和多变量线性回归模型。结果从2005年到2015年,所有四个定时物理测试(步态速度,定时向上移动,五次椅子站立和Moberg拾起)的调整后性能均得到了改善,女性增加+ 12.7%(95%CI + 10.5%; + 14.9%)至+ 20.4%(95%CI + 17.7%; + 23.0%),以及+ 10.6%(95%CI + 8.7%; +12.4) %)至男性的16.7%(95%CI + 13.4%; + 20.0%)。相反,样品的抓地力和平衡性没有改善。调整后的认知能力在追踪测试中没有显示变化,但是在两例女性的小心理状态测验,口语流利度和钟表测试中,样本之间的差异显着恶化(1.9%(95%CI 2.7%; 1.1%)至6.7%(95%CI 8.9%; 4.6%))和男性(2.5%(95%CI 3.4%; 1.6%)至8.0%(95%CI 11.1%; 4.9%))。结论在过去的十年中,定时进行的体格检查显着改善了66-71岁成年人的表现,但在较晚的样本中,大多数认知措施的表现都较差。男性为+ 12.4%)至+ 16.7%(95%CI + 13.4%; + 20.0%)。相反,样品之间的握力和平衡性没有改善。调整后的认知能力在追踪测试中没有显示变化,但是在两例女性的小心理状态测验,口语流利度和钟表测试中,样本之间的差异显着恶化(1.9%(95%CI 2.7%; 1.1%)至6.7%(95%CI 8.9%; 4.6%))和男性(2.5%(95%CI 3.4%; 1.6%)至8.0%(95%CI 11.1%; 4.9%))。结论在过去的十年中,定时进行的体格检查显着改善了66-71岁成年人的表现,但在较晚的样本中,大多数认知措施的表现都较差。男性为+ 12.4%)至+ 16.7%(95%CI + 13.4%; + 20.0%)。相反,样品之间的握力和平衡性没有改善。调整后的认知能力在追踪测试中没有显示变化,但是在两例女性的小心理状态测验,口语流利度和钟表测试中,样本之间的差异显着恶化(1.9%(95%CI 2.7%; 1.1%)至6.7%(95%CI 8.9%; 4.6%))和男性(2.5%(95%CI 3.4%; 1.6%)至8.0%(95%CI 11.1%; 4.9%))。结论在过去的十年中,定时进行的体格检查显着改善了66-71岁成年人的表现,但在较晚的样本中,大多数认知措施的表现都较差。但在两例女性的小精神状态检查,口语流利度和钟表测试中,样本之间的情况明显恶化(1.9%(95%CI 2.7%; 1.1%)至6.7%(95%CI 8.9%; 4.6%) )和男性(2.5%(95%CI CI%; 1.6%)至8.0%(95%CI 11.1%; 4.9%))。结论在过去的十年中,定时进行的体格检查显着改善了66-71岁成年人的表现,但在较晚的样本中,大多数认知措施的表现都较差。但在两例女性的小精神状态检查,口语流利度和钟表测试中,样本之间的情况明显恶化(1.9%(95%CI 2.7%; 1.1%)至6.7%(95%CI 8.9%; 4.6%) )和男性(2.5%(95%CI CI%; 1.6%)至8.0%(95%CI 11.1%; 4.9%))。结论在过去的十年中,定时进行的体格检查显着改善了66-71岁成年人的表现,但在较晚的样本中,大多数认知措施的表现都较差。
