The Prospective Physical Activity, Sitting and Sleep consortium (ProPASS)
ProPASS is an international research collaboration platform focused on cohorts using thigh and wrist-worn accelerometry devices (“wearables”). ProPASS’ main scientific aim is to explore the effects of multi-dimensional 24-hour physical activity, posture, and sleep patterns on a wide range of health outcomes. The objectives of the consortium are:
to establish a pooled data resource on physical activity, posture allocation, sleep, and health outcomes
to develop methods for processing, harmonising, and pooling wearables data
to support new international studies to collect wearables data, enabling prospective harmonisation
To expand the evidence base of 24-hour physical activity, posture, and sleep to under-represented countries, including LMICs
The ultimate goal of the ProPASS consortium as a data resource is to promote collaborative individual participant, and prospective meta-analyses on physical activity, posture, and sleep.
At inception in 2017, ProPASS employed a focus on thigh-worn wearables. The tremendous progress in wearables measurement and signal processing standards has provided the opportunity to expand to studies of wrist-worn wearables. In mid-2023, ProPASS initiated the expansion to wrist wearables studies which includes a rigorous program of methodological work on harmonising thigh and wrist captured data.
