OBJECTIVES: Remote work (ie, teleworking) may adversely affect physical activity (PA) among workers, while no strategies have been effectively implemented to curb this issue. We aimed to test whether a multi-component intervention program could promote the PA of remote workers. METHODS: This study was an 8-week pilot open-label randomized controlled trial. Fifty-one participants (19 women) aged 23 to 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 multi-component intervention that comprised individual (lecture, print material, goal setting, feedback, and posters), socio-cultural (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 sub-domain analyses divided into working and non-working days. RESULTS: No significant difference was observed in MVPA changes between the two groups. However, the intervention group showed significant improvement in light PA by plus 14.0 min/day (95% confidence interval (CI) 1.7 to 26.2). Sub-domain analyses also showed no significant differences in MVPA changes between the two groups. However, MVPA in the intervention group significantly increased by plus 9.4 min/day (95% CI 2.5 to 16.2) in working days. CONCLUSION: The present multi-component intervention was feasible for remote workers, while some revisions are necessary to enhance the effect size. TRIAL REGISTRATION: This study was registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN000046638).
