Randomized Controlled Trial Multicenter Study
Effects of a Multi-Component Workplace Intervention Program with Environmental Changes on Physical Activity among Japanese White-Collar Employees: a Cluster-Randomized Controlled Trial.
This study aimed to investigate effects of a flexible multi-component workplace intervention program for improving physical activity among Japanese white-collar employees in a cluster randomized controlled trial design. ⋯ This trial showed a significant and positive effect of the intervention program on physical activity. The program is unique because of its flexibility and feasibility. However, small worksites might receive less benefit from the program, indicating a need for further support and/or new technologies.
