This study aimed to describe the level of physical activity and its relation to fatigue and frailty during the COVID-19 pandemic in community-dwelling older adults aged 80 years and over. Three hundred and ninety-one older adults (aged 86.5 ± 3.00) completed a survey including physical activity, the Mobility Tiredness scale, and the FRAIL scale. Linear regression analysis was conducted to assess whether the variables age, sex, and physical activity (independent factors) were significantly related to fatigue and frailty. Respectively, 30.5% and 24.7% of the participants reported a decrease in walking and in energy-intensive activities; 25.4% reported increased sedentary behavior. A lower level of physical activity was associated with higher levels of fatigue and increased frailty risk (p < .05), independently from psychological symptoms. These results are important because participants with lower levels of physical activity and more sedentary behavior are more likely to feel fatigued and have higher risk to be frail.
本研究旨在描述80岁及以上社区居住老年人在新冠疫情期间的身体活动水平及其与疲劳和虚弱的关系。391名老年人（年龄86.5±3.00岁）完成了一项调查，内容包括身体活动、活动疲劳量表和虚弱量表。进行线性回归分析以评估年龄、性别和身体活动（独立因素）这些变量是否与疲劳和虚弱显著相关。分别有30.5%和24.7%的参与者报告步行和高强度活动减少；25.4%的参与者报告久坐行为增加。身体活动水平较低与较高的疲劳水平和增加的虚弱风险相关（p<0.05），且独立于心理症状。这些结果很重要，因为身体活动水平较低且久坐行为较多的参与者更容易感到疲劳，且有更高的虚弱风险。
