NCT02932787

Brief Summary

The purpose of this study was to look at the effects that height-adjustable workstations on occupational sitting time and workplace productivity in office workers. Participants workplace activity (sitting, standing and walking) and productivity was measured before the installation of the height-adjustable workstations. Workplace activity and productivity were then measured four weeks after the installation of height-adjustable workstations. The results were compared to a control group who received no intervention whilst the intervention had the height-adjustable workstations.

Secondary Outcomes (2)

  • Change in Workplace Absenteeism Using the World Health Organisation Health and Work Performance Questionnaire

    Baseline (0 weeks), 4 weeks after installation of height-adjustable workstations

  • Change in Workplace Presenteeism Using the World Health Organisation Health and Work Performance Questionnaire

    Baseline (0 weeks), 4 weeks after installation of height-adjustable workstations

Study Arms (2)
