When we talk about age, we generally refer to chronological age, that is, the one we know based on our date of birth. However, a person’s age encompasses much more than the years lived.
Biological age is a measure that reflects the health status and functioning of a person’s biological systems. In many cases, it is more accurate than chronological age when it comes to predicting the pace of aging, since individuals with the same chronological age can show significant differences in their health.
There are various factors and biomarkers that correlate with aging, making biological age a relevant piece of information for understanding the true aging state of our body.
Our influence on biological age can be both positive and negative. A healthy lifestyle can maintain or even reduce our biological age, while unhealthy habits can increase it. Some of the factors that influence biological age include:The methylation of our genes is a mechanism of epigenetic regulation that can activate or silence genes without altering the DNA sequence. This mechanism is a key biomarker of biological age, as it regulates the expression of genes essential for cell maintenance and repair.
As we age, changes in gene methylation can contribute to the loss of cellular functionality, the development of age-related diseases, and, overall, the deterioration of the body.
The AgingMETRIX test is a biological clock that analyzes the epigenetic methylation patterns of the ELOVL2 gene, which has been associated with chronological age across different populations, cell types, and tissues. The data obtained from the analysis allow for the calculation of biological age.
