Big Data Used to Reveal Health Trends: NIH Human Movement Study

Using a larger dataset than any previous human movement study, a team led by Scott L. Delp, Ph.D., James H. Clark Professor of Bioengineering and Director of the Mobilize Center at Stanford University, analyzed 68 million days of minute-by-minute step motion recordings from over 717,000 smartphone users of the Azumio Argus app from 111 countries. The study focused on 46 countries with at least 1,000 users. Delp explained that the new study provides user data taken in their free-living environments rather than self-reporting survey methods, and introduces a new frontier for health science data collection.
