Scientists Identify Biomarkers, Common Among People , Over 100 Years Old.br ScientAlert reports that centenarians have become br the world's fastest-growing demographic group, br nearly doubling every ten years since 1970.br A recent study published in GeroScience has identified br some common biomarkers in people over the age br of 90, including glucose and cholesterol levels.br The study was the largest ever comparing br biomarker profiles throughout the lives of br long-lived people and shorter-lived people. .br The research reportedly included data on br 44,000 people in Sweden who underwent health br assessments between the ages of 64 and 99. .br Out of these 44,000 individuals, br 1,224 lived to be 100 years old, br accounting for 2.7 of the overall group.br The vast majority of the centenarians br were female, accounting for 85.br The results found twelve blood-based biomarkers br associated with inflammation, metabolism, liver br and kidney function, malnutrition and anaemia.br The team found that having lower levels of glucose, br creatinine and uric acid from the sixties onward br greatly increased the chances of living over 100 years. .br ScienceAlert reports that the differences br between some biomarkers were rather small, br while others showed a more substantial impact. .
