A global platform to harmonize and share thigh-worn accelerometer data: Towards the next generation of sedentary behaviour, physical activity, and sleep guidelines


While it is well known that participating in moderate-to-vigorous physical activity is key in the prevention and treatment of non-communicable diseases, we know very little about the health properties of light intensity physical activity, sedentary behaviour, and sleep which collectively account for over 95% of the 24-hour daily cycle. In order to address this knowledge gap we need studies with accurate estimates of physical activity, sedentary time, and sleep. Currently, several large epidemiological studies worldwide are collecting such high-quality accelerometer (activity monitor) data.

Recently, a consortium of studies that have used thigh-worn accelerometers to measure posture and physical activity was established: the Prospective Physical Activity, Sitting, and Sleep (Pro PASS) consortium. In this project we will develop a state-of-the-art platform in which data from the studies in Pro PASS can be harmonized and shared with the scientific community for future pooled analyses on physical activity, sedentary time, sleep and health. For the first time, we will be able to examine prospective associations between light intensity activity, sedentary time, sleep and health using high-quality data from renowned population-based studies worldwide. Funding will be used to organise a two-day workshop in June 2019 in Maastricht with the WUN partners and Pro Pass consortium members.

It is becoming increasingly recognised that data sharing and large scale pooled analyses are the next generation of evidence that can answer complex scientific problems in uniquely powerful ways.This WUN RDF project will make unique contributions to future global guidelines for physical activity, sedentary behaviour and sleep and thereby aligns with the WUN Public Health Global Challenge to reduce the burden of non-communicable diseases.
