Analysis of Physical Activity Data from Over 700,000 Worldwide Users Reveals Physical Activity Inequality

Mobilize Center faculty member Jure Leskovec and colleagues published a paper in Nature this week where they analyzed physical activity data from over 700,000 users of a smartphone fitness app. Their analysis shows that the disparity of physical activity distribution within a country, what they refer to as “activity inequality,” is a better predictor of obesity levels within a country than average activity levels. In other words, the greater the activity inequality or activity disparity is in a country, the higher the prevalence of obesity. They also identify associations between a city’s walkability and activity inequality. Visit to access findings from the study, including data and code. Read more.
