Tracking Your 'Biological Age' Over Time May Predict Death Risk Better Than a Single Snapshot

Moderate Evidence·GeroScience·Apr 2026

In over 90,000 Dutch adults followed for nearly 14 years, people whose biological age ran ahead of their calendar age had a higher risk of dying. More importantly, among 25,000 people measured twice, those whose biological age sped up over time faced even greater risk. People stuck in a pattern of accelerated aging had a 39% higher mortality risk compared to those aging at a normal pace. The results suggest that checking biological age once might not be enough.

Key Insight

This study suggests monitoring biological age over time could be more informative than a one-time measurement.
