Your step count could reveal hidden health risks

This study follows 700 people with chronic diseases like arthritis, diabetes, or heart disease for 4 years. Participants wear a small movement sensor for 5 days, three times a year, to track their physical activity and sedentary time. Researchers want to see if a person's unique movement pattern—called a 'digital signature'—can predict whether they will develop additional chronic conditions. The goal is to find early warning signs so doctors can intervene sooner.
