![]() ![]() ![]() Study results have demonstrated associations of prolonged sitting time with premature mortality (1–3) chronic diseases such as cardiovascular disease, diabetes, and cancer (4–7) metabolic syndrome (5,6) and obesity (5,7). Prolonged sitting time (as a specific instance of sedentary behavior), independent of physical activity, has emerged as a risk factor for various negative health outcomes. Our findings suggest that using a sit-stand device at work can reduce sitting time and generate other health benefits for workers. Furthermore, the removal of the device largely negated all observed improvements within 2 weeks. The Take-a-Stand Project reduced time spent sitting by 224% (66 minutes per day), reduced upper back and neck pain by 54%, and improved mood states. We estimated change scores in sitting time, health risk factors, mood states, and several office behaviors on the basis of survey responses. We used experience-sampling methods to monitor sitting behavior at work during the 7 weeks of the project. The intervention group (n = 24) received a sit-stand device during period 2 designed to fit their workstation, and the comparison group (n = 10) did not. Project implementation occurred over 7 weeks with a baseline period of 1 week (period 1), an intervention period of 4 weeks (period 2), and a postintervention period of 2 weeks (period 3). We conducted our study during March–May 2011 in Minneapolis, Minnesota, among employees with sedentary jobs. We describe a practice-based study designed to reduce prolonged sitting time and improve selected health factors among workers with sedentary jobs.
