PURPOSE
The COVID-19 lockdown interrupted normal daily activities, which may have led to an increase in sedentary behavior (Castelnuovo et al., 2020). The aim of this study was to investigate the effect of the COVID-19 pandemic on the level of physical activity among Swiss office workers.
METHODS
Office workers from two Swiss organizations, aged 18-65 years, were included. Baseline data from January 2020 before the COVID-19 pandemic became effective in Switzerland were compared with follow-up data during the lockdown phase in April 2020. Levels of physical activity were assessed using the International Physical Activity Questionnaire. Paired sample -tests or Wilcoxon signed-rank test were performed for statistical analysis.
RESULTS
Data from 76 participants were analyzed. Fifty-four participants were female (71.1%). The mean age was 42.7 years (range from 21.8 to 62.7) at baseline. About 75% of the participants met the recommendations on minimal physical activity, both before the COVID-19 pandemic and during the lockdown. Weak statistical evidence for a decline in total physical activity in metabolic equivalent of task minutes per week (MET min/week) was found (estimate = -292, 95% CI from - ∞ to 74, -value = 0.09), with no evidence for a decrease in the three types of activity: walking (estimate = -189, 95% CI from - ∞ to 100, -value = 0.28), moderate-intensity activity (estimate = -200, 95% CI from - ∞ to 30, -value = 0.22) and vigorous-intensity activity (estimate = 80, 95% CI from - ∞ to 460, -value = 0.74). Across the three categories "high," "moderate," and "low" physical activity, 17% of the participants became less active during the lockdown while 29% became more active.
CONCLUSION
The COVID-19 pandemic did not result in a reduction in total physical activity levels among a sample of Swiss office workers during the first weeks of lockdown. Improved work-life balance and working times may have contributed to this finding.

目的
新冠疫情封锁措施打乱了正常的日常活动，这可能导致久坐行为增加（卡斯泰尔诺沃等人，2020年）。本研究的目的是调查新冠疫情对瑞士上班族身体活动水平的影响。
方法
纳入了来自瑞士两个组织、年龄在18 - 65岁的上班族。将2020年1月新冠疫情在瑞士生效前的基线数据与2020年4月封锁阶段的随访数据进行比较。使用国际身体活动问卷评估身体活动水平。采用配对样本t检验或威尔科克森符号秩检验进行统计分析。
结果
分析了76名参与者的数据。54名参与者为女性（71.1%）。基线时的平均年龄为42.7岁（范围为21.8至62.7岁）。在新冠疫情之前和封锁期间，约75%的参与者达到了最低身体活动建议标准。发现每周代谢当量任务分钟数（MET min/周）的总身体活动有微弱的统计学证据表明下降（估计值 = -292，95%置信区间为 - ∞至74，P值 = 0.09），但没有证据表明三种活动类型减少：步行（估计值 = -189，95%置信区间为 - ∞至100，P值 = 0.28）、中等强度活动（估计值 = -200，95%置信区间为 - ∞至30，P值 = 0.22）和高强度活动（估计值 = 80，95%置信区间为 - ∞至460，P值 = 0.74）。在“高”、“中”、“低”身体活动的三个类别中，17%的参与者在封锁期间活动减少，而29%的参与者活动增加。
结论
在封锁的头几周，新冠疫情并未导致瑞士上班族样本的总身体活动水平下降。工作与生活平衡及工作时间的改善可能促成了这一结果。
