Promoting Standing and Light Intensity Physical Activity in Office Workers

Sitting for large proportions of the day has become a major health concern. Emerging evidence associated prolonged sitting not only with musculoskeletal discomfort, but also increased mortality and morbidity as well as diabetes type II and obesity risk. Office workers are exposed to high levels of sedentary behaviours during work and leisure time. Regularly breaking up prolonged sedentary bouts, engaging in at least 2h of standing/light intensity physical activity and meeting the guidelines for moderate intensity physical activity has been shown to attenuate the deleterious effects of prolonged sitting. This research project aims to develop an evidence- and theory-based intervention to promote standing and light intensity physical activity in office workers and evaluate whether existing theoretical frameworks are sufficient to guide the intervention development process.
