What if you let them stand? A two-year follow up on sit stand desk

Objective Excessive sitting-time is linked to adverse health outcomes, with sit-stand desk (SSD) emerging as effective workplace interventions. However, evidence on long-term impacts is scarce. This study evaluates the effects of SSD on physical behaviors after 18 and 24-months. Methods Ten office workers were analyzed: 5 after 18-months (G-18 m) and 5 after 24-months (G-24 m) of SSD usage. Physical behaviors - sitting, standing, stepping, and sit-to-stand transitions - were objectively measured using activPAL pre- and post-SSD implementation. Results Significant reductions in workplace sitting-time were observed: G-18 m (-78.32 min, p = 0.019) and G-24 m (-84.36 min, p < 0.001). Both groups increased standing and stepping during work hours. No changes occurred during leisure-time (p > 0.05). Conclusion SSD use was associated with sustained reductions in workplace sitting-time over 24-months, suggesting a potential role in long-term health promotion. These findings support SSD adoption and emphasize the need for larger-scale studies.
