Abstract

Introduction: The COVID-19 pandemic lockdowns have reduced physical activity (PA) among home-dwelling older adults. The main aim of this study was to investigate how real-life PA in home-dwelling older adults changed over a year with gradual eases in COVID-19 restrictions.

Methods: Community-dwelling older adults (≥65 years) were recruited from local exercise groups aimed at preventing functional decline and falls. All participants had been involved in the exercise groups before the pandemic but had been without the offer for 6 months prior to inclusion because of COVID-19 restrictions. Sensor-based PA was measured using Axivity accelerometers worn on the lower back and right thigh for seven consecutive days at baseline (autumn 2020), 6 (spring 2021) and 12 (autumn 2021) months. PA activities were classified using the HAR70+ machine learning model, validated on older adults.

Results: Ninety-one older adults (78 ± 6.4 years, 88% female) were included. At baseline, 9% used walking aids and 26.5% reported a fall in the previous year. Daily time spent upright did not change, while time spent walking decreased by 8.19 min from baseline to 12 months (p < 0.048). Walking bouts of >10 min decreased with 0.5 bouts per day (p < 0.001), and the longest walking bout showed a nonsignificant decrease of 17.7 min (p = 0.056). This shows a change toward a more sedentary activity pattern over the year despite a gradual ease of the restrictions.

Conclusion: In a relatively well functioning group of older adults, PA did not increase with gradual ease in COVID-19 restrictions.

随着挪威COVID-19限制措施的变化，居住在社区的老年人在一年内的实际身体活动

导言：2019冠状病毒病大流行导致居家老年人的身体活动减少。本研究的主要目的是调查随着COVID-19限制的逐渐放松，居家老年人现实生活中的PA在一年内是如何变化的。方法：从当地运动组招募社区居住的老年人（≥65岁），旨在预防功能下降和跌倒。所有参与者在大流行之前都参加了锻炼组，但由于COVID-19的限制，在纳入前6个月没有参加锻炼组。在基线（2020年秋季）、6个月（2021年春季）和12个月（2021年秋季）连续7天，使用佩戴在下背部和右大腿上的Axivity加速度计测量基于传感器的PA。使用HAR70+机器学习模型对PA活动进行分类，并在老年人中进行验证。结果：纳入91例老年人（78±6.4岁），其中女性88%。在基线时，9%的人使用助行器，26.5%的人报告在前一年跌倒。从基线到12个月，每天直立行走的时间没有变化，而步行的时间减少了8.19分钟（p < 0.048）。每天步行0.5次（p < 0.001），最长步行次数减少17.7分钟（p = 0.056）。这表明，尽管限制逐渐放松，但在过去的一年里，人们越来越倾向于久坐不动。结论：在功能相对良好的老年人组中，PA没有随着COVID-19限制的逐渐放松而增加。

期刊介绍： In view of the ever-increasing fraction of elderly people, understanding the mechanisms of aging and age-related diseases has become a matter of urgent necessity. ''Gerontology'', the oldest journal in the field, responds to this need by drawing topical contributions from multiple disciplines to support the fundamental goals of extending active life and enhancing its quality. The range of papers is classified into four sections. In the Clinical Section, the aetiology, pathogenesis, prevention and treatment of agerelated diseases are discussed from a gerontological rather than a geriatric viewpoint. The Experimental Section contains up-to-date contributions from basic gerontological research. Papers dealing with behavioural development and related topics are placed in the Behavioural Science Section. Basic aspects of regeneration in different experimental biological systems as well as in the context of medical applications are dealt with in a special section that also contains information on technological advances for the elderly. Providing a primary source of high-quality papers covering all aspects of aging in humans and animals, ''Gerontology'' serves as an ideal information tool for all readers interested in the topic of aging from a broad perspective.
