‘Body watch’ could determine biological age and longevity, researchers say

Researchers have developed a new “body watch” tool that calculates the biological age of people, and could even predict the risk of disability or death.

The tool, which comes from the Faculty of Medicine of the University of Washington (UW), uses eight different physical examination and the blood work of a patient to determine the results, according to a UW press release.

The tool method, officially called the Octo Health tool, is detailed in Nature Communication magazine in a May 5 publication.

Researchers see this method as more comprehensive than current health evaluations, which generally focus on individual diseases instead of general well-being, according to the first author of the report, Dr. Shabnam Salimi, a doctor-scientific and interim instructor in the Department of Anesthesiology and Pain Medicine in UW.

Using data from large longevity studies, it was found that the octo health tool predicts disability, geriatric syndrome (a group of common health conditions in older adults), short physical performance battery (a clinical tool that evaluates the function of lower extremities in older adults) and mortality with 90% precision or greater, the study reported.

“A frame -based framework offers a new way to discover biomarkers and therapies that are directed to a specific aging of organs or the entire body, instead of individual diseases,” Salimi said in the statement.

The tool focuses on the “health entropy”, which covers the amount of molecular and cellular damage that the body has suffered over time.

That has a direct impact on the function of a person’s organs and general body systems, which can be used to determine how fast they are aging, the researchers said.

“Aging is a truly analog and non -digital process.”

The tool begins by assigning a “number of body organ disease”, which varies from 1 to 14, depending on whether the patient has experienced diseases that affect the heart, lungs, brain or other specific organ systems.

“Our findings showed that organ systems age at different rates, which led us to develop a specific age metric of the body system to reflect the aging rate of each organ system and the specific body clock to represent the intrinsic biological age of each organ system,” said Salimi.

Life expectancy in humans is not likely to increase much more, the study suggests

“Extending this concept to the entire body, we define the body’s clock as a measure composed of the general intrinsic age and the age of the body as the corresponding aging rate.”

Two of the tool components, the speed body clock and the age body age, measure how biological age affects the speed of walking.

The components of the disability body clock and the age of the disability body measure the impact of aging on cognitive function and physical disability, according to liberation.

A conclusion of the investigation was that some seemingly minor conditions, such as hypertension not treated early in life, could have a significant impact on aging in later years, according to Salimi. This indicates that treating these conditions could previously slow biological aging.

Looking towards the future, researchers plan to develop a digital application that people can use to track their own biological age, track how fast they are aging and measuring the impact of changes in lifestyle.

“Whether someone is adopting a new diet, routine exercise or taking drugs aimed at longevity, you can visualize how your body, and each organ system is responding,” said Salimi.

Dr. Brett Osborn, a Florida neurosurgeon who also directs a longevity practice, did not participate in the development of the tool, but commented on his possible benefits and limitations.

“This tool distinguishes itself based on its model on the physical findings of easily accessible physical exams and standard laboratory tests, offering a potentially practical framework for clinical application,” he told News Digital.

“An application is also being developed to empower patients and potentially encourage the development of health habits that will positively affect their health, or how long they will remain functional and free of diseases.”

The doctor also praised the octum tool approach in the system based on the system instead of the specific evaluations of the disease.

Osborn said, however, that there are limitations for this type of biological watches proposed, mainly that they cannot counteract the “inherent complexity of aging.”

“Aging is not a linear or totally quantifiable process: it is influenced by innumerable genetic, molecular, environmental and psychosocial factors known and unknown,” said the doctor.

“It is a truly ‘analog’ and ‘non -digital’ process. Therefore, it should not surprise that any model has captured all its landscape.”

The UW tool does not take into account certain genetic and DNA processes that influence biological aging, Osborn said.

“Aging watches also often have fallen short when applied in various populations or by predicting individual results (useful life),” he added.

“If you save a person’s life by calling your sick health, that’s a victory.”

Instead of determining absolute biological age, Osborn suggests using these tools to track trends over time.

“For example, tools such as octo health can help evaluate an individual’s response to interventions, be it a new exercise regime, medications or lifestyle change.”

The most important thing, according to Osborn, is to use comprehensive tests and monitoring as a springboard for the formation of lifelong health habits.

“If you save a person’s life by carrying their sick health (manifested as a downward trend) to your attention, that is a victory,” he said.
