ALSPAC includes Actigraph accelerometer data for approximately 5.5K and 3.2K participants at age 11 and 14 respectively. To date the data recorded by the accelerometer has been used to generate only a small number of phenotypes – moderate to vigorous physical activity (MVPA) and average counts per minute (CPM), a measure of total activity. There is much potential to extract other useful patterns from this data that may be 1) risk factors for 2) causally affected by or 3) causally affect, other phenotypes.

We will seek to identify common patterns in the accelerometer data and then investigate their relationship with other factors.
