Acute Effect of Height-Adjustable Workstations on Blood Glucose Levels in Women with Impaired Fasting Glucose Levels While Working: A Pilot Study

Objective: This study aimed to examine the effect on continuously monitored blood glucose (BG) among participants with impaired fasting glucose (IFG) who used a height-adjustable desk while working. Methods: The study was a repeated-measures pilot study in overweight or obese women who had IFG (BG >100 mg·dL⁻¹) and a sedentary job. BG was monitored with continuous glucose monitoring devices during two 1-wk periods at work: 1 wk in the seated position and 1 wk using alternate bouts of sitting and standing (by adjusting their desks) throughout the workday. Results: Ten women completed the study. Sedentary time significantly predicted BG independently of diet and overall physical activity (P = 0.02). Dietary carbohydrates, protein, and fat were significant predictors of BG (P < 0.001). Conclusions: Sedentary time is a strong predictor of increased BG in women with IFG and a sedentary job.
