Russian researchers have provided a new method of determining human biological age.
An average healthy individual has the same biological age and chronological age.
However, with age, these two indicators are likely to become mismatched, due to environmental factors, bad habits, manifestations of hereditary diseases and other factors.
To date, there has been no established method of predicting biological age. The new study is based on a combination of carotid ultrasound and tonometry data.
Using machine learning, a model was developed capable of determining the biological age of healthy men and women with a mean absolute error of 6.9 and 5.9 years, respectively.
The test set also included subjects with hypertension and Type 2 diabetes, whose biological age turned out to be, on average, three years greater than their actual age.
The group behind the research, published in the journal Aging, was lead by the Engelhardt Institute of Molecular Biology.
