Chronic Standing Desk Use and Arterial Stiffness

Area of Science:

• Cardiovascular Health
• Occupational Health
• Biomedical Engineering

Background:

• Prolonged sedentary behavior (≥10 hours/day) elevates cardiovascular disease risk by over 60%.
• Standing desks offer a potential intervention to reduce sedentary time and enhance cardiovascular well-being.
• While acute standing reduces pulse wave velocity (PWV), the long-term impact of chronic standing desk use on arterial stiffness is not well understood.

Purpose of the Study:

• To investigate the chronic effects of standing desk usage on arterial stiffness.
• To compare arterial stiffness in individuals using standing desks versus traditional seated desks.

Main Methods:

• A study involving 48 adults, divided into seated (n=24) and standing (n=24) desk user groups.
• Arterial stiffness was quantified using pulse wave velocity (PWV) measurements in the aorta, arm, and leg.
• Participants' age and aerobic fitness levels were assessed as potential confounding factors.

Main Results:

• No significant differences in carotid-femoral PWV (cfPWV) were observed between the standing desk group (6.9 m/s) and the seated desk group (6.6 m/s).
• Arm and leg PWV also showed no significant differences between the two groups.
• Secondary analysis indicated that age and aerobic fitness significantly modulated cfPWV in both seated and standing desk users.

Conclusions:

• Chronic standing desk use, even for more than 50% of the workday, did not alter arterial stiffness (PWV).
• Consistent with existing literature, age and aerobic fitness remain critical determinants of arterial stiffness.
• Future research may explore other physiological markers or longer-term interventions.
