Sit-stand workstations: a pilot intervention to reduce office sitting time.

Area of Science:

• Occupational Health
• Ergonomics
• Preventive Medicine

Background:

• Prolonged sitting time is a significant health risk for office-based employees.
• Sedentary behavior in the workplace contributes to various adverse health outcomes.
• Interventions to reduce sitting time are needed to mitigate these risks.

Purpose of the Study:

• To evaluate the effectiveness of a sit-stand workstation intervention in reducing sitting time among office workers.
• To assess the impact of reduced sitting time on health biomarkers.
• To determine the acceptability and preference for using sit-stand workstations.

Main Methods:

• A quasi-experimental pilot study design was employed.
• Participants included office workers (Intervention n=18, Comparison n=14) aged 20-65 in Brisbane, Australia.
• The intervention involved the installation of sit-stand workstations, with data collected using activity monitors and biochemical assays.

Main Results:

• The intervention group significantly reduced workplace sitting time by 143 minutes/day and overall waking time sitting by 97 minutes/day at 1-week, with effects maintained at 3 months.
• This reduction in sitting was primarily replaced by increased standing time.
• A significant increase in high-density lipoprotein (HDL) cholesterol was observed in the intervention group compared to the control group.

Conclusions:

• Sit-stand workstations can substantially decrease sitting time for office workers, both at the workplace and throughout the day.
• This intervention offers a practical solution for mitigating the health risks associated with prolonged occupational sitting.
• The study highlights the importance of objective measurements and comparison groups in evaluating workplace health interventions.
