Combining Wearables With Blood Proteins Sharpens Biological Age Tests

Key Insight

This research suggests that combining wearable data with blood biomarkers may give a clearer picture of biological aging.


Researchers built a new biological age model that combines blood protein data with wearable device readings. It predicted mortality risk better than either tool alone and cut prediction error by 21%. The model also flagged common drugs like GLP-1 agonists and ACE inhibitors as linked to a younger biological age in specific organ systems.
