Key Takeaway
Sit-stand desks reduce workplace sedentary time by 40-60 min/day but show limited impact on full-day sedentary behavior.
Summary
This systematic review synthesized evidence on how sit-stand desks affect sedentary behavior in office workers.
Sit-stand desks consistently reduced work-based sitting time by roughly 40-60 minutes per day. However, full-day sedentary reductions were smaller or non-significant, suggesting compensatory sitting outside work hours.
While sit-stand desks effectively break up prolonged sitting during the workday, they may not be sufficient alone for reducing total daily sedentary time.
Methods
- Systematic review of controlled studies
- Objective sedentary time measurement via accelerometry
- Separate analysis of work-based vs. full-day sedentary behavior
Key Results
- Work-based sedentary time reduced by ~40-60 min/day
- Full-day reductions smaller or non-significant
- Compensatory sitting likely occurs outside work hours
Limitations
- Heterogeneity across study designs
- Short follow-up periods in most studies
- Limited long-term adherence data
