Key result
Chronic standing desk use for more than 4 hours per day did not significantly affect carotid-femoral pulse wave velocity compared to seated desk use (6.9 vs 6.6 m/s, P = .47).
Why the study?
Acute standing lowers pulse wave velocity, but the chronic effects of standing desk use on arterial stiffness remain unknown.
Does chronic standing desk use improve arterial stiffness in adults compared to seated desk use?
Cross-Sectional (n=48)
No
Does chronic standing desk use improve arterial stiffness in adults compared to seated desk use?
Absolute Event Rate: 6.9% vs 6.6%
p-value: p=.47
Chronic standing desk use for more than 50% of a workday does not significantly improve arterial stiffness compared to seated desk use.
Chronic standing desk use did not reduce arterial stiffness; leaves open whether it improves cardiovascular outcomes in sedentary adults.
BACKGROUND: Sedentary activity and sitting for at least 10 hours per day can increase the risk for cardiovascular disease by more than 60%. Use of standing desks may decrease sedentary time and improve cardiovascular health. Acute standing lowers pulse wave velocity (PWV), but chronic effects remain unknown. The purpose of this study was to determine the effect of chronic standing desk use on arterial stiffness versus seated controls. METHODS: A total of 48 adults participated in this study. Twenty-four participants qualified as seated desk users (age 41 [10] y, body mass index 25 [4] kg/m2) and 24 as standing desk users (age 45 [12] y, body mass index 25 [5] kg/m2). Arterial stiffness was assessed as PWV within the aorta, arm, and leg. RESULTS: Carotid-femoral PWV (cfPWV) was not different between seated (6.6 [1.3] m/s) and standing (6.9 [1.3] m/s) groups (P = .47). Similarly, there were no differences in arm or leg PWV between groups (P = .13 and P = .66, respectively). A secondary analysis of traditional factors of age and aerobic fitness revealed significant differences in cfPWV in seated and standing desk participants. Age also significantly influenced cfPWV across conditions. CONCLUSIONS: Standing for >50% of a workday did not affect PWV. Consistent with previous research, fitness and age are important modulators of arterial stiffness.

Greenlund et al. (2019) conducted a cross-sectional in Healthy adult office workers (n=48). Chronic standing desk use vs. Chronic seated desk use was evaluated on Carotid-femoral pulse wave velocity (cfPWV) (p=.47). Chronic standing desk use for more than 4 hours per day did not significantly affect carotid-femoral pulse wave velocity compared to seated desk use (6.9 vs 6.6 m/s, P = .47).
