Abstract

Physical activity (PA) and physical function (PF) are modifiable risk factors for falls in older adults, but their ability to predict future fall incidence is unclear. The purpose of this study was to determine the predictive ability of baseline measures of PA, PF, and lower limb strength on future falls. A total of 104 participants underwent baseline assessments of PA, PF, and lower limb strength. Falls were monitored prospectively for 12 months. Eighteen participants fell at least once during the 12-month follow-up. Participants recorded almost exclusively sedentary levels of activity. PA, PF, and lower limb strength did not differ between fallers and nonfallers. Twelve participants, who reported a minor musculoskeletal injury in the past 6 months, experienced a fall. The results of this study suggest that in a cohort of highly functioning, sedentary older adults, PA does not distinguish fallers from nonfallers and that the presence of a recent musculoskeletal injury appears to be a possible risk factor for falling.

身体活动和功能的基线测量不能预测久坐老年人未来跌倒的发生率:一项前瞻性队列研究。

身体活动(PA)和身体功能(PF)是老年人跌倒的可改变的危险因素，但它们预测未来跌倒发生率的能力尚不清楚。本研究的目的是确定PA、PF和下肢力量基线测量对未来跌倒的预测能力。共有104名参与者接受了PA、PF和下肢力量的基线评估。对跌倒进行为期12个月的前瞻性监测。18名参与者在12个月的随访中至少跌倒一次。参与者几乎只记录了久坐不动的活动水平。PA, PF和下肢力量在跌倒者和非跌倒者之间没有差异。在过去的6个月里，有12名参与者报告了轻微的肌肉骨骼损伤，他们经历了跌倒。这项研究的结果表明，在一组高功能、久坐不动的老年人中，PA不能区分跌倒者和非跌倒者，并且近期肌肉骨骼损伤的存在似乎是跌倒的一个可能的危险因素。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
