Abstract text Introduction Excessive sitting time is a risk factor for cardiovascular disease and premature mortality independent of physical inactivity. Workplace interventions that reduce sitting time without interfering with work-related performance can inform work practices and organisational policy for occupational health. This study evaluated the feasibility and use of a sit-stand workstation for reducing workplace sitting time. Methods 26 of 47 eligible asymptomatic employees from one University in the North West of England were randomly allocated to an intervention group that received a sit-stand workstation (WorkFit-A, Ergotron Ltd) for 8 weeks. Time spent sitting, standing and walking during work hours was assessed at weeks 0, 4 and 8 via ecological momentary assessment diaries. Feasibility was assessed at 8 weeks via questionnaire. Repeated measures ANOVA assessed changes in sitting, standing and walking time over 8 weeks. Results At baseline, sitting time occupied 81% (mean 382.5 SD (56.7) min/d) of the working day. Compared to baseline, sitting time was lower at week 4 (295.0 (93.4) min/d, p=0.001) and week 8 (319.7 (101.0) min/d, p=0.066). Feasibility data suggest participants found the workstations easy and comfortable to use in front of colleagues. The workstation interfered with daily work-related tasks for 28% of participants. 66% of participants would use the workstation at work if offered to them by their employer. Discussion The sit-stand workstations trialled in this study reduced workplace sitting time by ~60 min/d after 8 weeks. Though feasible to use, the workstation interfered with work-related tasks for a minority of workers. Trials are warranted to determine the longer-term acceptance of sit-stand workstations and effect on work-related performance. Such trials should evaluate any associated benefits for physical, mental and social health, as well as additional organisation performance indicators such as cost-effectiveness. Contact
