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

ABSTRACT 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.
