Epigenetic aging

This graph illustrates the concept of epigenetic aging acceleration, which measures the discrepancy between an individual's biological age (as determined by DNA methylation patterns) and their actual chronological age.

Key Components

The Blue Line

Represents the average epigenetic aging trajectory. If an individual's data point falls precisely on this line, their biological age matches their chronological age.

Positive Epigenetic Aging Acceleration (Upper Region)

Individuals in this area have their "biological clock" ticking faster than average.

This often implies a higher risk of age-related diseases and functional decline, symbolized by the person in the wheelchair.

Negative Epigenetic Aging Acceleration (Lower Region)

Individuals here are "biologically younger" than their chronological age. This typically indicates better health outcomes and slower aging.

Understanding the Axes

• X-axis (Chronological Age): Your age in years since birth.
• Y-axis (Weighted Methylation Average): A mathematical score based on specific chemical markers on your DNA (epigenetic marks) used to estimate biological age.

In Summary

The vertical distance from the blue line indicates how much faster or slower an individual is aging compared to the general population.
