Working from home during the COVID-19 pandemic has affected many workers' daily life and possibly their physical activity behavior. We studied the longitudinal association of working from home during the pandemic with physical activity and sedentary behavior.
Longitudinal data from 17 questionnaire rounds of the Lifelines COVID-19 cohort (March 2020-February 2021) were used. In total, 33 325 workers were included. In every round, participants reported their current work situation: location, home, or hybrid (working on location and from home). Physical activity levels and sedentary behavior before and during the pandemic were asked. Logistic generalized estimating equations adjusted for demographic/work/health covariates were used to study the association of work situation with physical activity and sedentary behavior.
Home workers were less likely to meet the recommended ≥150 minutes/week of moderate-to-vigorous-intensity activity during the pandemic than location workers [odds ratio (OR) 0.93, 95% confidence interval (CI) 0.90-0.96] and more likely to be less physically active than before the pandemic (OR 1.09, 95% CI 1.04-1.14). Furthermore, compared to location workers, home and hybrid workers were more likely to be more sedentary (sitting ≥8 hours/day) on workdays during than before the pandemic (OR 1.51, 95% CI 1.39-1.64/1.36-1.68, respectively).
Compared to location workers, home workers (and to a lesser extent hybrid workers) were more often physically inactive and sedentary during than before the COVID-19 pandemic. As a substantial part of the working population may continue to work (partly) from home after the pandemic, workers should be supported to increase activity and reduce sitting while working from home.
新冠疫情期间居家办公影响了许多劳动者的日常生活，可能还改变了他们的身体活动行为。我们研究了疫情期间居家办公与身体活动和久坐行为之间的纵向关联。
本研究使用 Lifelines COVID-19 队列的 17 轮问卷数据（2020 年 3 月至 2021 年 2 月）。共纳入 33325 名劳动者。在每一轮调查中，参与者均报告其当前工作情况：地点、居家或混合（现场工作和居家办公）。询问他们在疫情前后的身体活动水平和久坐行为。使用调整了人口统计学/工作/健康相关协变量的逻辑广义估计方程来研究工作情况与身体活动和久坐行为之间的关联。
与现场工作者相比，居家工作者在疫情期间更不可能达到每周至少 150 分钟中高强度身体活动的推荐量[比值比（OR）0.93，95%置信区间（CI）0.90-0.96]，且与疫情前相比，其身体活动量更少（OR 1.09，95% CI 1.04-1.14）。此外，与现场工作者相比，居家工作者和混合工作者在工作日期间更可能久坐（每天≥8 小时），无论是在疫情期间还是之前（OR 1.51，95% CI 1.39-1.64/1.36-1.68）。
与现场工作者相比，居家工作者（居家和混合工作者程度较轻）在疫情期间比疫情前更不活跃和久坐。由于相当一部分劳动人口可能在疫情后继续（部分）居家办公，因此应支持劳动者在居家办公时增加活动量并减少久坐时间。
