Over 90% of the evidence used for guidelines development is based on questionnaires. In the last decade there has been a large increase in device-based cohorts that will likely inform the next generation of guidelines. Compared to questionnaires, devices such as accelerometers capture very different aspects of physical activity, posture and sleep. The symposium’s sessions will discuss the strengths and complexities encountered during the transition of future guidelines from questionnaire-based to accelerometer-measured evidence, and will highlight the instrumental role that ProPASS and other analogous consortia can play in enabling a smooth transition towards device-based and truly global physical activity, sedentary behavior, and sleep guidelines.
