An Analysis of “Sit-Stand Workstations” The “Sit–Stand Workstations: A Pilot Intervention to Reduce Office Sitting Time” study want to observe the effect of a novel tool on activity levels and overall health of office workers. The novel tool utilized was the “ErgoTron WorkFit-S Single LD Sit-Stand Workstation” (ErgoTron), which is a machine that transforms any type of work surface into one that is height adjustable, allowing for easy transitions between sitting and standing. The hypothesis was that the introduction of the ErgoTron would reduce the number of hours per day an office worker spent sitting down and positively impact the health of the experimental participants, particularly cholesterol, blood sugar levels, and weight. Study Design The study was a prospective, two-arm quasi-experimental study that aimed assessing the efficacy of a novel intervention, to reduce sedentary habits at work between February and June 2011. Methods Participants were recruited from 4 sites, with the experimental group (n=18) recruited from 1 site and the control group (n=14) recruited from 3 separate sites in order to minimize contamination of the control group. Inclusion criteria included: office workers between the ages of 20 and 65 years old who used a nonadjustable workstation. Exclusion criteria included: nonambulatory, pregnant at the time of the initial assessment, working less than part-time, and planning to relocate during the study period. 102 employees were contacted (24 for the experimental group and 78 for the control group) and 22 were subsequently enrolled and completed their baseline assessment, which consisted of a 10-hour fasting blood panel (blood lipids and glucose), height, weight, percent body fat, and a qualitative interview about fatigue, eyestrain, self-rate job performance, headaches, digestion, sleep problems, musculoskeletal health,
