Passive smartphone monitoring of people’s walking activity can be used to construct population-level models of health and mortality risk, according to a new study publishing October 20 in the open access journal PLOS Digital Health by Bruce Schatz of University of Illinois at Urbana-Champaign, U.S., and colleagues.
Previous studies have used measures of physical fitness, including walk tests and self-reported walk pace, to predict individual mortality risk. These metrics focus on quality rather than quantity of movement; measuring an individual’s gait speed has become a standard practice for certain clinical settings, for example. The rise of passive smartphone activity monitoring opens the possibility for population-level analyses using similar metrics.
In the new study, researchers studied 100,000 participants in the U.K....
