The development of novel outcomes from free-living physical behaviour and their relationship with determinants of health
By utilising the thigh inclination position captured by the activPAL activity monitor we can identify additional classes of activity, such as seated transport and lying, as well as measures of capability including sit to stand movements, which should allow us to classify a wider range of physical behaviours. By pairing this physical behaviour data with known indicators of health like BMI and VO2 max, it should be possible to investigate and identify outcomes that could act as digital biomarkers for specific diseases states, such as diabetes.
In this project we will use the accelerometer data captured by the activPAL activity monitor to investigate novel physical behaviour metrics, using the repeated observations to assess the consistency of these outcomes in the study population. We will then use the participant health and fitness characteristics that were collected as part of the iData study to test the value of these metrics as biomarkers for specific disease states and as indicators of general fitness.
• Characterise novel physical behaviour (PB) metrics using event-based activity data derived from thigh-worn accelerometer data obtained in free-living subjects
• Analyse the relationships between identified PB metrics and clinical measurements
