Prolonged sitting at the workplace coupled with a sedentary lifestyle is an equation for increased risk of cardiovascular disease. The use of sit-stand workstations (STS) not only decreases the amount of time that is spent sitting at the workplace, but previous research has found meaningful improvements in blood lipid profiles following workstation interventions. PURPOSE: The purpose of this study was to observe changes in blood lipid profiles over a six-month time frame between a group that utilized STS and a non-workstation group. METHODS: Faculty and staff from the University of Central Oklahoma were recruited via e-mail. Participants were randomly assigned to a treatment (TG) or control group (CG). Participants in the TG were given a workstation following baseline testing and expected to stand approximately 2 hours per day at their desk. Blood glucose (BG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and Total Cholesterol (TC), were measured by a lipid analyzer at baseline and six months. Participants were required to fast for at least 12 hours prior to completing a blood lipid profile. Researchers used a lancet to collect 5 μL of blood for analysis. A repeated-measures ANOVA was utilized to analyze differences between and within groups. RESULTS: The BG of both groups significantly (p = .00) decreased from baseline testing (CG = 91.29±2.40 mg/dL-1 to 86.071±2.36 mg/dL-1; TG = 97.39±2.12 mg/dL-1 to 90.11±2.08 mg/dL-1). The HDL and LDL did not significantly change between or within the two groups. The TC was also found to have no significant difference, but a meaningful improvement was observed between the two groups with the TG decreasing in TC from 189.82±7.48 mg/dL-1 to 185.06±7.64 mg/dL-1 (d=.13), and the CG increasing in TC from 177.36±8.24 mg/dL-1 to 181.29±8.42 mg/dL-1 (d=.18). CONCLUSION: This study found that a six-month intervention using a STS significantly decreases BG in both the TG and CG from baseline. Also, meaningful improvements were observed in TC in the TG.
