Accelerometer Study

Accelerometer Study

In SHARE Wave 8, data on physical activity were collected by using accelerometers. A subsample of the panel respondents were asked to wear the device (Axivity AX3) for eight consecutive days (day and night) on their upper thigh.

The SHARE accelerometer study was conducted in ten countries: Belgium, Czech Republic, Denmark, France, Germany, Italy, Poland, Slovenia, Spain, Sweden.

A detailed description of the study is available in the SHARE Wave 8 Methodology Volume.

Raw accelerometer data is processed with ActiPASS and GGIR and resulting measures are available in the Wave 8 gv_accelerometer modules. Variables based on ActiPASS provide information on postures and activities, e.g. sitting, lying, standing, walking, as well as intensity categories, i.e. sedentary, light, moderate, and vigorous activity. Activities detected by ActiPASS are available as 1-seconds intervals. Provided metrics based on GGIR include vector magnitude (ENMO), intensity gradient, and LXMX measures. Additional datasets with information on acceleration on epoch level (5 seconds) for each participant are available.

Raw sensor data is available upon request.
