Impact of a low-cost standing desk on reducing workplace sitting (StandUP UBC): A randomised controlled trial

Sit-stand desks can reduce occupational sitting time, however, their cost can limit scalability. The purpose of this study was to evaluate the impact of a low-cost standing desk on objectively-measured occupational sitting and prolonged sitting bouts over 3- and 6-months. Secondary outcomes included self-report work engagement and occupational fatigue. Forty-eight office employees (91.7% female, M_age = 39.8 ± 10.1) were randomized to receive a low-cost standing desk or to a control group. At 3-months, the intervention group sat 0.7 h (42min) less at work compared to the control group; F(1, 45) = 5.90, partial η² = 0.12, p = .019. The effect was small, yet comparable to findings from studies using costlier alternatives. However, these reductions were not maintained at 6-months. No changes in prolonged sitting bouts or secondary outcomes were found. There is some potential for low-cost standing desk converters as a scalable workplace health intervention.
