Remote work (ie, teleworking) may adversely affect physical activity (PA) among workers, but no strategies have been effectively implemented to address this issue. We aimed to test whether a multicomponent intervention program could promote the PA of remote workers.
This study was an 8-week pilot open-label randomized controlled trial. Fifty-one participants (19 women) aged 23-58 years were recruited via an information technology company in Tokyo, Japan, and randomly assigned to the control (n = 26) or intervention (n = 25) group. The intervention group was provided a multicomponent intervention that comprised individual (lecture, print material, goal setting, feedback, and posters), sociocultural (supportive atmosphere and team building), and organizational (encouraging message from an executive) strategies. The control group only received posters. The primary outcome was an 8-week change in objectively measured moderate-to-vigorous PA (MVPA). The secondary outcomes were changes in light PA, moderate PA, vigorous PA, steps, and sedentary time. We also conducted subdomain analyses divided into working and nonworking days.
No significant difference was observed in MVPA changes between the 2 groups. However, the intervention group showed significant improvement in light PA by +14.0 min/d (95% CI, 1.7-26.2). Subdomain analyses also showed no significant differences in MVPA changes between the 2 groups. However, MVPA in the intervention group significantly increased by +9.4 min/d (95% CI, 2.5-16.2) on working days.
The present multicomponent intervention was feasible for remote workers, although some revisions are necessary to enhance the effect size.
远程工作（即，远程办公）可能会对工人的身体活动（PA）产生不利影响，但尚未采取有效的策略来解决这一问题。我们旨在测试多组分干预方案是否可以促进远程工作者的 PA。
这是一项为期 8 周的试点开放性随机对照试验。51 名参与者（19 名女性）年龄在 23-58 岁之间，是通过日本东京的一家信息技术公司招募的，并随机分为对照组（n=26）或干预组（n=25）。干预组接受了包括个体（讲座、印刷材料、设定目标、反馈和海报）、社会文化（支持性氛围和团队建设）和组织（来自高管的鼓励信息）策略在内的多组分干预措施。对照组仅收到海报。主要结局是客观测量的中等至剧烈 PA（MVPA）的 8 周变化。次要结局是轻 PA、中 PA、剧烈 PA、步数和久坐时间的变化。我们还进行了子域分析，分为工作日和非工作日。
两组之间 MVPA 变化无显著差异。然而，干预组在轻 PA 方面显著改善，增加了 14.0 分钟/天（95%CI，1.7-26.2）。子域分析还显示，两组之间 MVPA 变化无显著差异。然而，干预组在工作日的 MVPA 显著增加了 9.4 分钟/天（95%CI，2.5-16.2）。
本研究中的多组分干预措施对远程工作者是可行的，尽管需要进行一些修订以提高效果大小。
