A new US study published on Monday, to better understand the mechanisms of aging in humans . What to allow medicine one day delay? Explanations.
The first signs of aging can be detected in the mid-twenties, according to a US study published Monday. The researchers, who published their findings in the journal Proceedings of the National Academy of Sciences , studied the metabolism of a group of 954 people born in New Zealand in 1972 and 1973.
They studied their kidneys, liver, lungs, teeth, blood vessels, metabolism and immune system at the age of 26, 32 and 38 years. With 18 different data to measure the state of health and aging, the researchers stopped a “biological age” for each participant, at the age of 38 years. At this age, some were in a state of aging of a person below 30 years, others for nearly 60 years.
Those who are aging faster start 26 years
In addressing those who are aging quickly, they found signs of aging and damage from the age of 26 years, namely the youngest age at which the data was collected for this study. These people, the researchers said, have a biological aging of three years in a year, when most participants in the study age, as expected, a biological year by year or less.
Those whose body the most rapidly aging also had “the worst results in tests generally subject to the people over 60 years, as tests of balance, coordination and problem solving,” it said in this study.
Slow Aging?
These findings “give us hope that medicine might be able to slow aging and offer people more active years,” said Terrie Moffitt, lead author of the study, professor of psychology and neuroscience at Duke University. The authors also believe that this kind of study paves the way for a better understanding of aging from the younger years, when still time to act to prevent certain diseases.
Previous research had put demonstrated that the genetic aspect entered into account only 20% in aging. The main causes being the behavior in terms of health and the environment.
