Physical activity insights from mobile phone and accelerometer data

Physical activity insights from mobile phone and accelerometer data

This is a talk I gave at the "Overcoming Barriers to Movement and Physical Activity Seminar", organised by the Movement and Physical Activity Network at the University of Leeds.

I argue that we need good data in order to devise solutions for overcoming barriers. I cite work from two recent papers, one which utilises accelerometer data and one which used mobile phone app data.

The citations for the papers discussed in the talk:

  2. Overcoming Barriers to Movement and Physical Activity • We need

    data • How do patterns vary? • Can we better target interventions?
  3. Accelerometers • Traditional study design • Short term data collection

    • Only good for acceleration based measurement • Often detailed demographics
  4. Mobile phone based apps • Longer term collection • Greater

    equity • Multiple activity types • Secondary data • Missing context

  15. The demographics of activity • Female users walk significantly fewer

    steps than males • Male users record both a higher average number of activities a day and a higher average number of different activities whilst using the app • Female users recorded longer duration activities on average than the male users. • Users living in more affluent areas had a higher average daily step count and recorded more diverse activity types • However, they record significantly fewer minutes of activity than the users living in less affluent areas
  16. None
  17. Overcoming Barriers to Movement and Physical Activity • We need

    data • How do patterns vary? • Can we better target interventions? • 23% of adults globally are not sufficiently active • 34% of men and 42% of women in the United Kingdom (UK) not active enough for good health • one in six UK deaths can be attributed to physical inactivity
