by According to a report published in PLOS Digital Healtha studythe passive monitoring of people’s walking activities by smartphones can be used toConstructPopulation-level models of health and mortality risk. In the new study, researchers studied 100,000 UK Biobank national cohort participants who wore activity monitors with motion sensors for a week. While wrist sensors are not worn the same way as smartphone sensors, their motion sensors can both be used to extract information about walking intensity from short walks — a walking test in everyday life. Using only 6 minutes of steady walking per day collected by sensors, combined with traditional demographic characteristics, the team successfully validated a predictive model of mortality risk.
