在新冠肺炎大流行期间，在家工作的人大大增加了，人们担心这会改变身体行为。在本研究中，11名巴西上班族(5名女性，6名男性；平均年龄39.3[9.6]岁)在新冠肺炎(2019年9月)之前连续5天佩戴两个固定在上背部和右大腿上的三轴加速度计，包括周末(2019年9月)，并在新冠肺炎期间(2020年7月)在家工作时再次佩戴。我们测定了五种行为所用的时间：久坐、站立、轻度体力活动(LPA)、中等强度活动(MVPA)和卧床时间。使用成分数据分析处理有关这些行为的数据，并使用重复测量Manova比较感染COVID19前和感染COVID19期间观察到的行为。在-COVID19期间的工作日，参与者有667分钟久坐、176分钟站立、74 LPA、51 MVPA和472次卧床；对应的COVID前时间分别为689分钟、180分钟、81分钟、72分钟和418分钟。试验证实，COVID19前的卧床时间较少(对数比−为0.12[95%CI−0.19；−0.08])，而MVPA时间较长(对数比为0.35，[95%CI 0.08；0.70])。周末期间的行为只有轻微的变化。虽然规模较小，但这项研究是第一次报告在新冠肺炎大流行之前和期间对同一受试者在工作日和周末进行的客观测量的身体行为。
Work from home has increased greatly during the COVID-19 pandemic, and concerns have been raised that this would change physical behaviours. In the present study, 11 Brazilian office workers (five women, six men; mean [SD] age 39.3 [9.6] years) wore two triaxial accelerometers fixed on the upper back and right thigh continuously for five days, including a weekend, before COVID-19 (September 2019), and again while working at home during COVID-19 (July 2020). We determined time used in five behaviours: sedentary, standing, light physical activity (LPA), moderate-to-vigorous activity (MVPA), and time-in-bed. Data on these behaviours were processed using Compositional Data Analysis, and behaviours observed pre-COVID19 and during-COVID19 were compared using repeated-measures MANOVA. On workdays during-COVID19, participants spent 667 min sedentary, 176 standing, 74 LPA, 51 MVPA and 472 time-in-bed; corresponding numbers pre-COVID were 689, 180, 81, 72 and 418 min. Tests confirmed that less time was spent in bed pre-COVID19 (log-ratio −0.12 [95% CI −0.19; −0.08]) and more time in MVPA (log-ratio 0.35, [95% CI 0.08; 0.70]). Behaviours during the weekend changed only marginally. While small, this study is the first to report objectively measured physical behaviours during workdays as well as weekends in the same subjects before and during the COVID-19 pandemic.
