Individuals age at such differing rates that some grow older three times faster than other people of the same age, a new study has found.
US scientists who conducted the study on a group of 38-year-olds found that their biological ages ranged from 28 to 61.
Expert created 18 measures to determine how quickly a person is ageing, including tests of kidney, liver, lung and immune system function as well as assessments of metabolism, cholesterol, heart health, lung function, and the length of telomeres – protective caps on the ends of chromosomes.
The study’s 871 participants were previously enrolled in the Dunedin Study, which has documented the health of around 1,000 New Zealanders born between 1972 and 1973.
To study the pace at which participants aged, scientists measured the 18 biomarkers when the participants were 26, 32, and 38-years-old.
