Research question(s):
The aim of the study 1 will be to examine the associations between total physical activity volume, intensity, and type with cardio-metabolic outcomes.
The aim of study 2 will be to examine the associations between compositions of movement behaviors (physical activity, sedentary behavior and sleep) and cardio-metabolic outcomes.

Abstract:
Physical activity improves health. However to date, all observational studies have relied on self-reported or count based cut-point methods to measure the health effects of physical activity, sedentary behaviour, and sleep. These methods are susceptible to high rates of misclassification and recall error. In the ProPASS (Prospective Physical Activity, Sitting, and Sleep) consortium, all physical activity, sedentary behaviour and sleep measures will be harmonized with standardized methods using thigh-worn accelerometry data. The
application of pattern recognition techniques using thigh-worn accelerometry data will allow for sedentary behaviour and all dimensions of physical activity- frequency, intensity, and duration- and activity type to be measured continuously and more accurately. This will provide more precise estimations of the relationships between habitual physical activity, sedentary behaviour, and sleep with cardio-metabolic outcomes.
