A study by Washington University in St. Louis focused on analyzing the biological age of 148,724 individuals.
They used a set of blood biomarkers and found that people born after 1965 were 17 percent more likely to experience accelerated aging compared to those born between 1950 and 1954.
For the researchers, biological age reflects the physiological state of the body, influenced by factors such as diet, physical activity, and environmental stress.
The study also identified nine blood markers that are correlates of biological age: albumin, creatinine, glucose, C-reactive protein, and the percentage of lymphocytes, the Mean Corpuscular Volume (MCV).
