A reduction in sedentary behavior has been associated with improvements in metabolic health. Because a disproportionate number of working hours for office-based employees are spent engaged in sedentary behavior, an increase in workplace activity is substantiated. PURPOSE: The purpose of this study was to determine if the use of a sit-to-stand workstation (STS) effected blood lipid profiles following a 12-month intervention. METHODS: Participants of the study included volunteer faculty and staff of the University of Central Oklahoma who were randomly assigned to a control group (CG) or an intervention group (IG). A STS was provided to the IG with participants being instructed to stand at least 2 hours every work day. Blood lipid profiles were used to measure high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), total cholesterol (TC), and blood glucose (BG) at baseline, 6, and 12-months of the intervention. The data was analyzed using a repeated-measures ANOVA. RESULTS: No significant differences were found between groups (p\u3e.05). Small, non-significant improvements occurred for the IG in HDL and LDL over time and a significant change in BG across all groups took place over time (F2,23=8.05, p=.00). Descriptive and inferential statistics can be found in Table 1. One outlier was removed from analysis. CONCLUSION: Significant differences did not occur between STS participants and those using a typical workstation; however, some benefits may be gained from breaking up bouts of sedentary behavior. Future research may examine the effects of longer standing time to ascertain the efficacy of the STS
