United States: Centenarians, people who live to be 100 or older than that, were once considered or thought to be extremely rare, but today they are the fastest-growing age group globally. Since the 1970s, their numbers have roughly like almost doubled every ten years of gap, and the trend shows no signs of slowing down.
As medical advancements and healthier lifestyles continue to improve, more people are living longer, making centenarians a more common part of the population than ever before.
As early as when human began to exist, questions on how long they will live, or how long they are expected to live a healthy life for have been of interest. Lycurgus and Solon wrote about old age, and so did Plato and Aristotle, more than two thousand three hundred years ago.
But it is not always easy to chase the knowledge about the mysteries of this longevity, though.
As reported by the Science alert, it encompasses understanding the system of genes and life events and the way they are connected with each other at different stages of a person’s life.
Now a study done in GeroScience this year has revealed some of the biomarker familiar to participants, such cholesterol and glucose levels in 90 plus persons.
Scientists have long focused on nonagenarians and centenarians out of hope that they could discover the secrets of longevity and healthy aging.
To date, available research on centenarians is usually local in scale, and often limited to specific sub-sample, such as community or institutionalised centenarians only.
Huge dataset
Our study is the largest to date to directly contrast biomarker profiles over the whole life span or post-mortem between IPLP and their counterparts in the shorter-lived population.
We distinguished two groups: centenarians and controls and looked at the biomarker composites of both and the relationship between the biomarker composites and the likelihood of becoming a member of this ‘club’.
In our study we used information from 44 000 Swedes who underwent health examination at the age of 64-99 – they were a subsection of the so-called Amoris cohort.
These participants were then followed through Swedish register data for 35 maximum years. Among these people 1,224 (2.7%) of them achieve the status of centenarian and died. A preponderance of the participants (85%) were females for this analysis the sample was taken from a larger database of participants aged a hundred years and above.
These included twelve serum-derived biomarkers representing inflammation, metabolism, liver-kidney functions, malnutrition, and anemia.
