The COVID-19 pandemic has triggered national recommendations encouraging people to work from home (WFH), but the possible impact of WFH on physical behaviors is unknown. This study aimed to determine the extent to which the 24-h allocation of time to different physical behaviors changes between days working at the office (WAO) and days WFH in office workers during the pandemic.
Data were collected on 27 office workers with full-time employment at a Swedish municipal division during the COVID-19 outbreak in May-July 2020. A thigh-worn accelerometer (Axivity) was used to assess physical behavior (sedentary, stand, move) during seven consecutive days. A diary was used to identify periods of work, leisure and sleep. 24-h compositions of sedentary, standing and moving behaviors during work and non-work time were examined using Compositional data analysis (CoDA), and differences between days WAO and days WFH were determined using repeated measures ANOVA.
Days WFH were associated with more time spent sleeping relative to awake, and the effect size was large (F = 7.4; p = 0.01; η = 0.22). The increase (34 min) in sleep time during WFH occurred at the expense of a reduction in work and leisure time by 26 min and 7 min, respectively. Sedentary, standing and moving behaviors did not change markedly during days WFH compared to days WAO.
Days working from home during the COVID-19 pandemic in Sweden were associated with longer duration of sleep than days working at the office. This behavioral change may be beneficial to health.
COVID-19 大流行促使各国提出建议，鼓励人们居家办公，但居家办公对身体活动的潜在影响尚不清楚。本研究旨在确定在 COVID-19 大流行期间，上班族在办公室工作（WAO）日和居家办公（WFH）日之间，24 小时内不同身体活动的分配时间发生变化的程度。
2020 年 5 月至 7 月 COVID-19 爆发期间，我们对瑞典市政部门的 27 名全职上班族进行了数据收集。使用大腿佩戴的加速度计（Axivity）评估连续 7 天的身体活动（久坐、站立、移动）。使用日记记录工作、休闲和睡眠的时间。使用组合数据分析（CoDA）检查工作和非工作时间内久坐、站立和移动行为的 24 小时组成，并使用重复测量方差分析确定 WAO 日和 WFH 日之间的差异。
WFH 日与清醒状态相比，睡眠时间更长，效应量较大（F=7.4；p=0.01；η=0.22）。WFH 期间睡眠时间增加（34 分钟），而工作时间和休闲时间分别减少了 26 分钟和 7 分钟。WFH 日与 WAO 日相比，久坐、站立和移动行为没有明显变化。
瑞典 COVID-19 大流行期间居家办公日比在办公室工作日的睡眠时间更长。这种行为变化可能对健康有益。
