The association of working from home (WFH) with physical activity (PA) and sedentary behavior (SB) has been explored; however, this association during periods without stringent measures to combat coronavirus disease 2019 is undercharacterized. Particularly, few studies have evaluated the potential effect modification on its associations. Therefore, this study aimed to investigate the associations of WFH frequency with accelerometer-measured PA and SB, along with its effect modifiers, among Japanese white-collar workers during the later pandemic period.
A cross-sectional study involving 1133 white-collar workers residing in the Tokyo metropolitan area was conducted between April 2022 and March 2023. WFH frequency was evaluated through a self-report questionnaire, while SB and PA during weekdays were measured using a triaxial accelerometer. Linear regression models adjusting for potential confounders were used to examine the association of WFH frequency with PA and SB.
Regardless of activity intensity, individuals who worked at home, even for 1 to 2 days per week, demonstrated lower levels of PA and higher levels of SB as compared with those who did not (P < .05). For example, difference between never and ≥5 days per week WFH was approximately 70 minutes/day for total PA and about 4000 steps/day for step counts. Associations between WFH and decreased PA were more pronounced in workers who were older, female, less educated, in sales and service work, nonregular staff, and precontemplating changes in exercise and eating habits.
We report that WFH was associated with decreased PA and increased SB in Japanese white-collar workers with pronounced associated in several subgroups.
已经探讨了在家工作（WFH）与身体活动（PA）和久坐行为（SB）之间的关联；然而，在没有严格措施对抗 2019 年冠状病毒病的时期，这种关联尚未得到充分描述。特别是，很少有研究评估其关联的潜在效应修饰。因此，本研究旨在调查在大流行后期，WFH 频率与日本白领工人的加速度计测量的 PA 和 SB 之间的关联，以及其效应修饰因素。
在 2022 年 4 月至 2023 年 3 月期间，进行了一项涉及东京大都市区的 1133 名白领工人的横断面研究。WFH 频率通过自我报告问卷进行评估，而工作日的 SB 和 PA 则使用三轴加速度计进行测量。使用调整潜在混杂因素的线性回归模型来检验 WFH 频率与 PA 和 SB 的关联。
无论活动强度如何，与不 WFH 的人相比，每周在家工作 1 至 2 天的人 PA 水平较低，SB 水平较高（P <.05）。例如，从不 WFH 与每周至少 5 天 WFH 之间的差异大约为每天 70 分钟的总 PA 和每天大约 4000 步的计步数。WFH 与 PA 减少之间的关联在年龄较大、女性、受教育程度较低、从事销售和服务工作、非正规员工以及考虑改变锻炼和饮食习惯的工人中更为明显。
我们报告称，WFH 与日本白领工人的 PA 减少和 SB 增加有关，在几个亚组中存在明显关联。
