Biological age vs chronological age12/8/2022 ![]() ![]() Test results of most people will fall where the majority of the test results for their age fall. Biological aging refers to the study or understanding of cellular or molecular aging in the body of the person. Your biological age, however, is how old your body seems, based on several factors. It’s the years, months and days that have passed since you were born. Statistical analysys is used to establish a trend. Your chronological age is how old you are. This new way of determining age is broken into two categories. Test result values of those biomarkers are recorded. Scientists are now classifying a person’s true age based on how well they are in mind and body. ![]() DNA methylation or telomere length in samples of blood or saliva) in a large and diverse group of population. Many biomarkers decline roughly linearly with age with a slope of <1% per annum ( Jackson, 2003 ). In part, that mathematical modeling is based on the fact that a biomarker of aging typically closely correlates with chronological age, it changes as a person ages. To calculate someone's biological age, scientists use a combination of biomarkers and mathematical modeling ( Jia, 2017 ). chronologically.īiological age is a concept used to indicate how 'old' a person is compared to a population cohort and the average life expectancy in that population cohort ( Jackson, 2003 ).īiological age and biomarkers of aging are two concepts that are used together. Biological age considers where the person is on the maturation and development front, while chronological age does not. When we are talking about biological age, we are talking about how young (or old) a person is biologically, functionally vs. ![]() Instead, the term ' biological age' was introduced over 50 years ago to predict susceptibility of a person to morbidities and mortality better than chronological age does. Many visual signs such as wrinkles or grey hair are not a reliable predictor of a person's state of health and of the expected life span and health span either. However, aging happens in different people at different rates, and therefore chronological age is not the best indicator of how long a person will live and whether and when that person will experience any old age disease. Increased chronological age is closely associated with the risk of death and old age disease.Ĭhronological age means exactly what it sounds like - how many years a person was born. This study was unique in that it did not focus its aging research on older subjects. Rejoice, for your chronological age is, in fact, just a number However, your biological age can reveal a great deal about your general health and the rate at which you are aging. It affects all cells, tissues, and organs in our bodies. A groundbreaking new study confirms that people age at different rates. Aging is a complex process characterized by accumulation of damage, an increase in the vulnerability to disease, decline in the reproductive function, in physical and mental abilities. ![]()
